Title: Show your Multimeter!
Post by: Professor Fudge on September 03, 2010, 06:04:08 pm
Here are a bunch of the multimeters I have had throughout my life.
(http://lh5.ggpht.com/_AAE2EfIR57M/TIEz-IhL-ZI/AAAAAAAAAA8/6u_YjYvQtKc/s800/Multimeters.JPG)

On the left is my first one I got as a kid from my dad. I did some projects with the boy scouts with it. Its a Hung Chang HC-213.
Next is a GB Instruments GDT-11 I got as a teenager to put together an intercom kit and trouble shoot a doorbell with.
The green one is a Greenlee DM-40 home depot special cheapo meter I use to check mains voltage at work. I also use the ohms and continuity on it.

The big yellow one on the end is what I purchased recently for $40 on ebay. Its a BK test bench 389.
I have been using it building a bunch of kits and just starting to really learn about electronics and I like it!

Ok now show me what you got!!

*chuckle*

Seriously, I have two Fluke 77's that are probably 20 years old, work great, are still in cal, and I see no need to replace them.
(and yes, that's really one of my meters in the photo)

Personally , after all this gear that I recently own or build , about  multimeters accuracy verification,
I do not throw my hat , if I do not test first the meter .

I am less sentimental ..  :)

I have an unbranded one.  :(

I would like to have a better one... a Fluke would be awesome.

Yes - it has a built-in AC/DC current measuring clamp. Very handy for diagnosing car electrical problems. 

BTW the small blue Pantec Zip pen-style unit has to be about 20 yrs old now. As far as I know, nobody makes something this small today  - the nearest I've found so far is the one above it in the pic.

That's a Mastech MS8226T I got for college and my dad's old Fluke 8021B. They are the only meters I have that measure properly in the presence of strong harmonics. In the picture, they are being used to measure the impedance of a transformer out of an old UPS, which has an AC impedance of 814 ohms at 100Hz. (I'm using my PC as a DDS function generator, and my best friend Tiffany Yep, a digital communications engineer/model, says hi...)

The Tiffany Yep plasma ignition system was named after her. (It's an inside joke, "Tiffany Yep lights the fire in my cylinders, even when the mixture is lean and wet.")

The relevance of the picture of Tiffany Yep is that she designs how to generate and interpret communications signals digitally, and the program I'm using (baudline) digitally generates and interprets signals.

pretty close, still a little bigger. but has current ranges :) Diode test only 1.4V  :(

BTW the Pantec is 27x18x140 (155 with probe). A couple of the above look like decent replacements so I'll take a closer look - thanks for the info - I'd not seen any of those before.

Sorry for the confusion there. It's my misunderstanding and careless reading that got those two on the list. I recently won an Extech (on twitter) which is described as a pen style "DMM" (and which I haven't received yet so no first hand experience). The description on the Extech site for these two was for a multifunction voltage tester - since I had DMM in my mind from the contest I didn't actually read the description. My bad.

I think if I had to choose one for electrical work, the Hioki looks the most interesting.
Title: Re: Show your Multimeter!
Post by: mikeselectricstuff on September 10, 2010, 09:05:43 am
Yes - was looking at the Hioki but seems to be a wide range of pricing -Westside shows $38 but they don't ship outside USA. I found a UK dealer but they list at GBP59!

It might be worth contacting someone at tequipment.com (they carry it) and asking whether they can match the Westside price.

I've heard the new Keithley bench meters are plagued with issues. Plenty of faults and firmware bugs apparently that Keithley won't address.
Quite a few people have complained about them on the various forums in the last few years.
If true it's a shame because Keithley meters used to have an awesome rep.

I think it's mainly about their latest 'budget' bench meter (model 2100?), haven't heard many complains about their more expensive / older models (model 20xx), and none about the 2000 as far as I can recall. But I agree it's bad for their reputation as a trusted brand. The 2100 was probably an attempt to compete with the 'low-cost' products from Agilent and Fluke (eg. Agilent 34405A), it wouldn't surprise me if it was designed outside Keithley. Either that or they fired their competent engineers.

Just had to showoff the new one :)

(http://i234.photobucket.com/albums/ee40/sparkdup/electronicsblog/all4.jpg)

The Old AVO 7 is well out of spec but the meter movement is still nice and the switches are nice to use. It was my granddads, he liked valve radios.

The cheapy with the transistor testers I have had for over 20 years and is basic 0.5%  +/-1 Its been great for a hobby meter, No input protection (just a glass fuse) so not for any circuits with power behind them.

The other AVO digital was an Ebay bargain the  bargraph is a bit intermittent but the meter is good. I did have an AVO junior in a tan leather case but I dont know what happened to it the memory is  gone on that one.

I have mostly only been familiar with the 2700 series of ~10 years ago and some of the daq gear of the same vintage. I love the 2700's I've used, great meters.   Sorry about the long response time, I am in the process of moving and will not have internet at home until tomorrow.

I can't believe I'm posting this....... Mind you, I'm even older than this meter!

Actually, Beckman meters were quite good in their day, and I'm happy with the performance of this unit, found at a Ham Radio flea market for a paltry sum of money and rescued from a leaking 9v battery.

I still pine for a *modern* auto ranging meter, but with the 87 V kerfuffle, I'm glad I held back when I first caught sight of one. Agilent has a promising unit, as do some other makers..... but I'm going to wait to  hear what happens with the Fluke..... if less than stellar response to the rf issue..... I may opt for the 28 II or simply go with the Agilent as it's pretty attractive, price wise in Canada. Until I spring for a new meter, the Beckman will forge on.... backed up by a couple of One-hung-low brand extra cheap meters I'm too embarrassed to post pictures of.

No pics but a brand spanking new Fluke 87V arrived at my mailbox today!  ;D

Funny thing is that it agrees exactly with my ancient Beckman at the voltages I most commonly monitor....  Still, nice to have a second decent meter that can confirm the other one is still working right.

What is the purpose of this display?  These are just electric meters, instruments.  It is very common item in handy men or handy women shop or house hold garage.  Here is mines:
Fluke 12, stuck buttons and need cleaning often
Fluke 187
Fluke 175
Tektronix handheld from Taiwan
Tektronix parts tester, but lift out the inductance of a coil measurement from Taiwan
Philips PM2518
Philips PM2505 analog
Hantek DSO
Radio Shack Micronta analog multimeter
HP Yokogawa low end multimeter E series from the 1990.  It has very little current protection.
HP-3468A with battery inside it.

My dream multimeter is the Agilent U1253B in orange, but I do not need it and I have very little to no work for the last three years.

Protip: The 125* series has two protectors: the big gomey shipping contact film is obvious. But you probably didn't even notice the one underneath it. If you look closely at the edges of the silkscreened type on the glass, you can see that there's a laminate layer over it. And if you look at the very edges of the glass, you can see where the edges of the film are.

Ah yes after pulling away the larger ugly one I can see the blistering of the second film over the silk screening.  That makes the decision to remove the large one much easier.

The more I use it, the more I think the OLED screen is underrated. It's true that it's basically useless in sun. Not bad in shadow, but no LCD, and literally invisible in even mild direct sun. However, the tradeoff for how much nicer it is on a bench than the segmented LCD displays is TOTALLY worth it. Not just the visibility and contrast, but that combined with the fact that its a matrix. It's just generally much easier to navigate than the 1252. They could have gotten the best of both worlds with a matrix LCD, but it obviously wouldn't have been nearly as visible as either of the others inside OR outside.

In general, though, I'm getting more and more willing to suck it up and put a shade over it if I need to read it outdoors, or just use my not-as-good LCD meter.

Post by: saturation on April 01, 2011, 02:17:52 pm
Very true, K.  In the early days of 7 segments LED, some of the segments would blow but later, good ones are still alive today.  Only time will tell.  I have some color LCD in game boys or PDAs and colors seem more washed out, but the B&W or grey scale ones still look OK.

The OLED isn't any worse that the 7 segment in sunlight.  That's partly a reason I wrote earlier it would be better indoors in a bench-like DMM, with mains power.

This is some of my family of multimeters.

(http://77.101.225.32/Images/IMG_1855.JPG)

From left to right in chronological order:
1. Fluke 25, I have owned it for 20 years. Got is second hand and dates inside of it say 1984, so it's probably about 27 years old. Just as accurate as ever. It's got different leads though, the originals fell apart a couple of years ago.
2. Fluke 79III, I have owned from new for about 15 years. No problems.
3. Kewtech KT116, had it about 3 years. Pretty good meter, I carry it about in my laptop bag. It goes wherever I go - a bit like a camera.
4. BK Precision 879B LCR meter. Dave twisted my arm with his review. Bought it a few months ago.
5. Fluke 287. I have owned it several hours now.

I have also got one of those wallet meters. I think it's at work now.
Also got a nasty meter that lives in the "winter motoring" crate. It's pretty inaccurate, but it'll get you out of trouble if required.

All,

I have a question about my Voltcraft M-4660M (= Metex M-4660M), maybe there is someone able to explain this to me.

This meter has de capability of power-masuerement (Wattmeter) plus calculation of price of used power. You can enter a price per kWh, set a specific duration of mesurement (e.g. 24 hours) and it calculates the total cost.

I have a Power-adapter for the meter witch is connected to COM+V/Ohm+20A.
For the 20A-bus it has the text "Max 30sec EACH 15min".
If I would like to mesuere some heater (or wathever) from about 18A for 24 hours, how can I do that without damaging the shunt.
It look likes this is impossible, the meter can only handle 18A for 30 seconds.

This issue is bothering me for quite some time.
Thank you.

Post by: alm on October 10, 2011, 07:35:56 pm
The 30s limit is because the shunt will overheat at 20A continuous, it relies on thermal inertia to keep the temperature down.

Measuring real (as opposed to apparent) power requires both the current and the voltage to be sampled at the same time, and each sample to be multiplied (instantaneous product). I think this DMM can perform this operation (just like the Kill-A-Watt type devices), but only if the current is fed via the 10A jack. This makes it hard to use external shunts or current clamps. They would need a current output instead of the more common voltage output, and the current should be in range of the meter.

The normal solution would be to use an external current shunt rated for 20+A and measure the voltage across this shunt (which is exactly what the current measurement feature does). A current clamp would be another solution if you desperately want to spend money, the current is very high or if disconnecting the device under test is a big deal. This will not work with the power measurement feature, however, so all you can do is calculate apparent power by multiplying RMS voltage with RMS current. Plus you would need two logging multimeters.

If the heater is resistive, this may not be a big deal, since it will have a power factor (difference between real and apparent power) close to 1, so the error will be small.

A Kill-A-Watt type device (check the max. current rating and duty cycle) may be a better, cheaper and more convenient solution.

Thank You alm for your answer.

I think this DMM can perform this operation (just like the Kill-A-Watt type devices), but only if the current is fed via the 10A jack.
This is the whole clue (I had this idea olso before).
The adapter they sold can only be used in the 20A-connector...

Long story short (if I understand you correctly), they sell a DMM wich is not cappable to do what the specs/manual suggest (mesure 20A for many days).
I still don't understand why they sell it like this.

One last question: if I would like to have a decent Watt-meter, is a Gossen Metrawatt Energy capable for this?
(not that I do a lot of watt-masurements, but I'm just wondering).
Title: Re: Show your Multimeter!
Post by: alm on October 10, 2011, 09:25:04 pm
The Gossen will do it, with an optional external current clamp. The internal shunt of the Gossen Metrahit Energy is about 60 mOhm. At 20A, it would have to dissipate 24W. That's a lot for an enclosed case. A lower resistance shunt would decrease the resolution.

External shunts don't have this problem, since they can dissipate more heat, and can be low resistance since they don't have to measure down to 600mA. Clamp meters barely have any dissipation, which makes them extremely useful in the 100-1000A range.

If the heater control alternates between switching it fully on and off, you may be able to measure the on (within 30s) and off power, and then log the time spent on and off separately. Then multiply on power with on time.

There is no super fast HRC fuses  above the 15A mark, so far I have not see any.
And so it looks normal so far, the DMM to be set to serve at 15A and lower.

So you can see what the meters looks like.
I agree that everyone know what the Fluke 179, 87, 337 and T+Pro looks like (as they are very popular meters), but it might not be so for the Ideal and Hioki ones.

I've already said that I don't have my Kodak at hand. (Sister borrowed it)

Anyway. I don't see where the problem is, since if I took the pictures myself, you would have seen the exactly same meters.

If it were a machine or a circuit that I've made, then, I agree, I would have to take a picture myself.

Post by: Aldem on March 17, 2012, 12:16:57 am
Thanks !

These Hioki clamp meters are not very high rated (CATIII 300 V and CATII 600 V)

There's no back light, it uses a watch battery (CR2032)

I use it only for the clamp, when there's not enough place for the Fluke 337 =)

Already posted my heap of junk in some other Metrix related thread, but oh well, here I go again.

Check out the bodge wires. What the fuck did they think when theyx designed that board? Beats me.

I've had too many to count I think.
Dave, what is that one on the right (your left in the picture?) The analog with the large red switch? I have one that my dad gave to me that looks very much like it! When I get home from my trip to texas I will check the brand and model number. Mine came from Eastman Kodak in Rochester. Hell, most of my family on my dad's side retired from there, back when they actually made things like cameras and film. Anyway, got excited cause that meter looks awefully similar.

It seems my DM is a rare one on this forum. I have a Sanwa PC510.
I had an Extech 330 until a few weeks ago when i discovered a bug in its software and i had to return it.
So far i am very satisfied with this one, it does what is supposed to

After measuring continuity for a few seconds, switch to DC voltage, shake the probes a few seconds (you will see a lot of voltage measured on the display) and then try to measure a 1.5 AA battery. Mine and all the others from the shop were showing >120 volts

I could not reproduce it on mine (luckily). What do you mean by shaking probes? When switching to DC after beeping the continuity (and still floating the probes) it shows around 0-300mV. Then probing a voltage source (battery or anything) it measures roughly 2x voltage for the first read and then the real voltage for the others.

Good to hear, maybe the lot which arrived here in Romania had this flaw.
By shaking the probes i mean keep them by the wire close to the probe and shake them up and down.
Mine was showing >100x voltage and had to be turned off to work again.

LE: Just don't ask me how i discovered this bug, can't remember why i was shaking the probes :) I guess i was thinking at something

I am finally halfway finishing my bench, so I had some room to take a picture.

This is not all of them I got another Fluke 77V in my car and couple other pocket multimeters, I think my son has some of them, he is also studying electrics. 
One of my Duspol testers is at work, this one on the picture is new, I got it at least 10 years but never used it, it’s just spare.
Unfortunately I lost my first couple multimeters in the years.

Enough said:

I just love the 87 series ones, I want to get a 87 IV but when you put them all side by side you can see the digits getting bigger with each one. I just love meters

Nice collection Pstevenson, I got the Uni-T UT10A too actually 2 of them. It has the largest digits between all my pocket dmm’s and it kind a works okay, I like the Amprobe one little bit better.

I am looking for Benning MMP3 or a UEI DM5B, Benning looks really decent to have around but UEI has current measurement till 5 Amps  :o I mean thats a lot for a pocket dmm and it would be great for the work I do as I am a enchanted electrician (electrics engineer)  ;D, I am not on the field as I was before because I got 4 technicians working for me but still time to time I jump in when shit hits the fan.

 I should find all my pocket dmm’s and make a review about it :D and update my picture above too with the pockets and the 3 new Gossens i got.

well , I am setting up my lab , so I have 3 meters and I am working for another budget (for rigol-1052E oscilloscope ) and maybe function gen and counter are next ,

I know that 5.5 digit HP-3478A 303,000 count and the 4.5 digit 50,000 count fluke 287 are over kill for newbie like me , but I wanted a high quality meters and low drift one's (I am working hard for the budget so call me stupid or so will not match the reality ) and all of those cost me total of 781.3$ (including in't shipping and customs )  farther more - the fluke 87-V and HP-3478A are used (the HP came calibrated within the 170$ price ! ) , Quite surprisingly the fluke 87-V came well-well within speck and by few of he's voltage ranges he follows tight to the hp as well as +-1Dgt (the 287 is only by +- 3Dgt while quoted out by 20 on mVDC)

The Agilent U1241A meters were clearance items from RS (First one turned up with no leads so they sent me another one. They didn't want the first one back!). The Fluke 8840A was from ebay - 10GOhm input impedance up to 20V, works great apart from a fading VFD display.

not my actual meter, but the same as mine, just too lazy to take a pic and upload it.

i also owned a ut30 (if memory serves) which i passed on to my little brother, a good unit for under €15
the ut60 set me back just over €60 but has earned its keeping over and over again.

I eventually got its software to run under windows7 but the refresh rate of the captured waveform is too slow to be useful

Just found this thread when searching for something I was looking on eBay - I feel that I should post my multimeters too.

1. HP3468A, got it off eBay for £60 incl postage.
2. VC97.
3. VC99, bought these two off eBay too. Both work fine for my hobbyist needs, £50 for both VC97 and 99.
4. DT-830B, I knew it was gonna be a piece of crap, but I still bought it to find out 'how bad can a dirt cheap DMM be', this one was £4.99 free post. It was CRAP, I had to ditch the test probes and solder a pair of leads to it -  the sockets have a thick layer of oxidised copper and the probes were flimsy. Well, for less than a fiver, I can't ask for too much.
5. This one is in the 2nd picture, it's part of a 'Universal Electronics System' (more details here: https://www.eevblog.com/forum/product-reviews-photos-and-discussion/metex-universal-combined-test-instrument-systemsstations-a-look-inside/ (https://www.eevblog.com/forum/product-reviews-photos-and-discussion/metex-universal-combined-test-instrument-systemsstations-a-look-inside/)). I bought the whole 'system' for £50 incl delivery. The DMM was dead so the seller refunded me £25. I later managed to fix it. Again, it's probably not a great DMM, but hey, it's good enough for me. And for £25 you get a 19999 count DMM, a tripple output (0-30V 2A, 5V 1A, 15V 2A) power supply, a crappy function gen and an "ok" frequency counter I think it's a good deal.
6. I recently bought a Solartron 7075 off eBay for £29, it seems 'working', will add to the thread when it was confirmed working or repaired.
7. (Not in the pictures) I have 2 analog meters and an earlier version of DT-830 (or something similar) that I bought 20 years ago when I was a kid. They were left somewhere in my parents house back in China after I went to university - will find them when I next visit my mom&dad.


oh, the shiny Rigol DS1102 is my new piece of kit that I got from Germany last week :) after my old CRO is dead (will still try to repair it)...

Title: Re: Show your Multimeter!
Post by: PA4TIM on August 27, 2012, 05:19:04 pm
The stackable bananas in the same color of the wire are just cheap cables from conrad. I use them normaly not for measuring.

The fat yellow cable is triax. Got two versions. One has a bnc on one end ( and a bnc to bnana adapter on the meter) and the outer shield is used for shielding.

The other version has 3 bananas on each side. The bananas are good quality gold plated lammelle versions. This cables I can use for guarded or shielded measurements. Also have 4 wire cables, plus/minus, 2 x sense and the shielding for shield  or guard. This for calibrators, kelving connections, 4 wire powersupplys ect.

I also have made cables made from RG58. Two bannanas on each side. Use them unabllanced but also 2 paralleled. The shields in that case for instance as shielding or guard. In some cases a guard on the input ( measure) cable and grounded at the output( source)
Title: Re: Show your Multimeter!
Post by: AndyC_772 on August 27, 2012, 05:25:44 pm
I guessed they're ordinary stacking banana plugs, with DVM probes plugged in that have 4mm adapters attached.

I stay from the VC99 because it's just awful
Title: Re: Show your Multimeter!
Post by: PA4TIM on August 27, 2012, 06:49:11 pm
According the specs ( for what they are worth) the Unit-t 61E
It is 0.1% instead of 0.5% DC. So 6V on the VC is 5.967 to 6.033 so no much use or 6000 count.
The VC is AC avarage measuring upto a lousy 400Hz, this is realy prehistoric. But most important, imput protection is max 250VDC
The unit-T had 1000VDC protection and meaures upto 10KHz AC. Only thing I do not understand s why they talk about TRMS for only 10-100% of the range ?? Combined with a crestfactor of only 3 makes me think it is not TRMS at all.

My multimeter is so cheap it is not even worth taking a picture of, and some might even be offended by seeing it, so cheap is it.

It is a $15 from adafruit, and all I need it to do is pretty much to just let me know around what voltage I got... I haven't made anything that critical yet, and does not need super accuracy to just be able to pull a relay or make a led light up :)

OK, here's mine.

I bought the Supertester 680R in 1978, when I lived in the UK. It's got tons of sentimental value to me but it's a crappy meter--inaccurate and dangerous. Who else used these?

I picked up the Sanwa in Akihabara when I lived in Japan. It was cheap, and has a nice clamshell cover, so it's convenient to toss in a bag. It must be 15 years old now, but the same model is still in the Sanwa catalog. Notice the captive leads--no banana plugs. Be careful with that dial...

I got a good deal on the Simpson on eBay. Don't use it much, but it sure smells good. Made of Bakelite.

The Flukes are the meters I actually use.

It was a long time ago, so I don't remember what I paid, but list price today is Y6800. You can usually get a little discount in Akihabara if you ask for one. "Makete Itadaketara..."

I noticed on eBay that they are available in the US for $50, including shipping.

Post by: JuiceKing on August 30, 2012, 10:43:42 am
It's a mystery how the eBay sellers are making them available for half the price in Japan...with free shipping worldwide from Shanghai and Hong Kong, no less. If these eBay specials are for real, my guess is that Japanese customers are getting a raw deal on a meter that's manufactured in China.

The exchange rate was something like Y130/$ when I lived there, but today its Y78/$. If you earn and spend in Yen, these fluctuations aren't so noticeable, but a different story for foreign visitors.

When it comes to multimeters you don't need, surely you're better off selling than buying in Japan!

My beloved EX210...

I'm not sure how "mini" it is compared to the others, but the size and IR are very handy. I was trying to measure my forehead temperature near a cat, I am still recovering. I last used it to measure my toast's thermal time constant.

Ahem... Sort of spawned in interest out of Dave's EX330? suggestion, wanted to have something different, and it was on sale for $60 or so on eBay!

I would have wanted cap measurement (will get a fluke, or better, an LCR later) and for frequency/duty measurement...I've already got something lovely behind that to measure *funny feelings somewhere*

Updated. Recent acquisitions include Simpson 260-6XLPM analog VOM and 373 analog milliampmeter, the dual Hameg HM8011-3 bench DMMs, and a cheap, mystery-meat LCR meter labeled only "4070L" from eBay that tends to read a bit high, but at least it is consistent. The red one in the middle showing all 8s is a Extech EX31X rebadged as a Sears Craftsman (my knock-around-the-house/toolbox meter) and the inevitable accumulation of $3 cheapies up top that have their place in the world (as long as that world is DC and not much over 12 volts).

Not shown is an assortment of older Fluke and Racal-Dana bench jobs that are too crusty to trust anymore. Oh, and my trusty RCA VVTM, a WC-97C, complete with optional high voltage (10kV, 1 gigohm) probe, plus a Viz clone of the same RCA VVTM for parts.

Aside from a Fluke 87 and perhaps a better LCR meter, whats left to get? I mean, I love collecting these things and all, but from a functionality standpoint, I think I pretty much got it covered.  :-/

How well does your 4070L work for you? Mine is very useful even though it tends to measure everything about 10% high in all ranges. Its predictable and can be compensated for, but still annoying. Wondering if I can recal it somehow...

Found something old in the junkbox, a Triplett model 60 (http://www.triplett.com/products/analog-testers/detail/6-analog-testers/flypage/26-model-60?sef=hcfp) type 2. Not sure about the age, probably late 70s / early 80s.

Interestingly it has inverted plugs. Also notice the range switch mechanics, it looks like it uses wooden inserts. The switch itself feels very nice.
Also someone seems to have "repaired" the fuse with a piece of wire

Sure I haven't had it for long but my first impression is favorable it seems very accurate the build quality seems better than my Amprobe. I like the features. Very configurable some people complain about the slow continuity mode but for some applications I like a meter that waits for a steady connection before alerting. I like the logging capability the place I ordered mine from was backordered on the Bluetooth adapter because of the free with purchase promotion going on. But I look forward to logging data to my phone. I like the variety of temperature functions including differential temperature and ambient temperature overall a great meter for 200 bucks.

IF they didn't people are going to complain about agilent giving them CAT II probes on a CAT III meter
But i'm not sure about one thing though, if i recall correctly agilent used to give both the shrouded CAT III probe and the CAT II probe set U1169A for the U1272A

My Agilent 1252 came with a nice etui, long good silicon cable, four probes ( shrouded and normal, two ver good clip on crocodiles, three clipon mini grabbers with 20 cm extra thinner cable and two ultra tin very long ( about 10 cm) neeldelike tips. All thos things go on the not-shrouded probes)
Title: Re: Show your Multimeter!
Post by: perfect_disturbance on September 16, 2012, 02:27:50 pm
They must include a full probe kit with their more expensive meters. I looked at the documentation and it seems like the 4mm probes are all that's supposed to come with this one. Don't get me wrong their nice silicon leads and good quality probes but I would have also liked a 19mm set. But I can get an u1169a for 30 us dollars and have an extra set of leads. So not a super big deal.

Mine is not very accurate also but it works for its price. I don't use it much anyway. Have an ESR meter that works for me most of the cases (mine measures only capacitance).

Found my first serious multimeter. A Dynatek 7010, "Made in Taiwan 1990", so I got it when I was 13 or 14.
Absolute crappy design by todays standards. The PCB sits loose in the case, so everything moves when the knob is turned.
The sockets are sort of safety style, but not compatible with the standard safety socket.
Very little protection on the inputs, 20A range is not fused at all, and the lower amp range uses a simple 20x5 glass fuse.

BTW, since the Vichy/Victor/Whatever 4070L was the topic of some discussion, I thought I would do a mini-teardown and review on it.

(Edit to add for archival/search purposes: it is actually made by HoldPeak in China:

http://www.holdpeak.com/0/Productshow.aspx?id=20063 (http://www.holdpeak.com/0/Productshow.aspx?id=20063)

(Thanks to bored@work  for the link :-)

As noted above, accuracy is not its strong suit (mine reads about 10% high on average), but its the cheapest (+/- $25) way to measure inductance and stretch your available ohms and capacitance bandwidth beyond what your typical DMM will do. As I had a pressing need to measure inductance and was about broke at that point, I gambled and gave it a shot. It turns out to be quite useful, but hardly a definitive example of type.

BTW, of note up front is that it is totally unfused and clearly marked on the front as "MAX 30v DC" on all inputs. After poking around inside, you had better believe that I have taken those limitations to heart. This meter is somewhere between a CAT-0-rating and a small hand grenade for use at anything much higher.

The rubberish/soft plastic armor peels off with some difficulty. Its so stiff and thin that it can hardly provide any shock resistance at all.

Two screws (including the threaded insert battery cover screw) and you are in. Eight more little screws and you have the main board out. Not much to it. The display is interesting in that the LCD is mounted in the front cover with two long flexible connectors at the top and bottom hooking it electrically to the main board.

Sandwiched in between is a remarkably simple and effective (and cheap) way of backlighting the LCD: a thin translucent layer of plastic to conduct light from a single white LED mounted to the side. My Extechs should have half as good a backlight, and better than most anything else this side of, what? Agilent? Fluke? Not sure even they work much better. Kudos for shipping a cheap meter with a good backlight.

It has three tiny trimpots on the board. Perhaps it could be more precisely calibrated on the ohms and capacitance ranges, at least within the limits of my Hameg bench DMMs, but as this is the only inductance meter I have , I cant do much with that measurement. Might try that later.

It apparently has some means of testing transistors built into the face as well, but I didn't test that, as I gather such things are typically about useless anyway.

Photos below. I hope this is of some use to anybody.

Hm, fair enough, not the same one. Really annoys me when people do that, because it was blatently obvious that the guy was using multiple accounts to drive up the price, continually relisting under other accounts with slightly edited descriptions and photos taken in the same place from different angles. Nobody pays more than about £25-30 for these from what I can see, but I bid on the same one three times and got edged out literally at the 1s mark repeatedly, only to see it relisted under a new account a few days later.

So as a counterweight for all the far-east plastic here a meter that was build to last for ever.
The cabinet is wallnut with a copper shield inside. Accessoires are under the toplid. And the nicest thing is a illuminated scale. You can choose between 10M or " infintive" input resistance.
Its almost as new but I miss the original diode for AC. ( a glass one  like in a Hp410 or AVO CT-38, the kind that is nice in winter because they get comfy warm  :)

I have the typical 8000 series bench Flukes and a trusty old 77 which I use but I'll bore you with a few unique early meters in my test equipment collection.

Supreme Instruments 1934  model 222 "Multometer".  Back then test equipment was functional art.
(http://www.supremeinstruments.org/pics/supreme222.jpg)

This one is just a Continuity Tester but interesting just the same.  It's from the late 1920s.
When a short is detected across the two chrome bars the red dot on the needle moves out of the window on the meter. If the dot does not move the item under test is open.
(http://www.stevenjohnson.com/pics/testometersm.jpg)

The Manhattan DC Polarity-Indicator was patented in 1905 and shows polarity in a DC circuit using a liquid in a glass tube that when current is passed through it, the liquid in the negative end turns red. They used a liquid filled glass tube that is in a hard rubber type case with a connector on each end. Electrodes inside the glass tube attach to the connectors. The metal sleeve can be rotated to cover the glass windows when carried in your pocket.
(http://www.stevenjohnson.com/pics/polarity3.jpg)
FYI:  They still work!

The Simpson 221 (around 1951) - Interesting as the meter scale mechanically rotates with the range selection knob so you don't read the wrong scale.

Am i correct if I think it is able to measure leakage current at a variable voltage ? Still hope to find something like that some day ( i use my homemade one  very much)

PA4TIM,  I like your site also.  I have the Tektronix TM-504 on my bench also with the following plug-ins:  function generator, DMM, Counter, and dual power supply.  On of these days I'd like to find the oscilloscope plug-in for it. Don't need it but I would like to see how well it works.

Here's the info on the 650A:  Made around 1940.  Pretty much a fixed voltage around 45 V for testing and variable for leakage tests.

USAGE NOTES
·  The "test voltage" control knob only applies to leakage tests. All capacitance
tests are done at around 45 volts a.c. combined with just over 10 volts d.c., so
don't test any capacitor on your 650A that's not rated for 50 or more volts.
·  On paper/mica leakage tests, it takes 3 microamps of leakage to keep the eye
tube from fully opening (~40 megohms of insulation resistance). If leakage is
under 3 microamps, the eye tube will open fully.
·  For electrolytic leakage tests, 0.5 milliamps is the leakage threshold at which the
eye tube will open.
·  The power factor control only applies to the CH and C1 ranges.
·  When all buttons are released (out), any capacitor attached to the terminals
discharges through a 200 ohm resistor. Let any capacitor you test discharge
before removing it, and make sure the buttons are fully released. Any button
being pressed or stuck in even by a small amount will keep the discharge circuit
from being completed, so be aware of potential voltages on your cap's if your
buttons don't release fully.
·  The higher the value and higher the voltage used for leakage tests, the longer it
will take for the eye tube to open. Be patient with large caps, it can take a few
seconds.

I actually use a Sprague  TO-5 on my bench.

I think it is the lens which is broken not the LCD.
If only somebody could explain me an easy method to remove those lenses... I need to replace two such lenses on my multimeters.

Title: Re: Show your Multimeter!
Post by: SeanB on November 08, 2012, 08:36:46 pm
They probably do have them in a warehouse as spare parts for the repair of meters sent in by large organisations with a service repair calibration agreement. they might be expensive though.

To replace you just take the meter apart and gently pop the old one out ( or brute force it out without breaking the front housing) and glue the new one in. Or you order the whole front casing half as a unit.
Title: Re: Show your Multimeter!
Post by: Rick on November 08, 2012, 08:58:50 pm
OK thanks. I tried to force them but they resisted well. I was afraid to break the whole front housing. How about heating the front housing gently with a hot air gun from a certain distance? I mean just the region where the lens is and especially the borders of the lens.

I think it's pretty funny that I ended up with so many red meters.   

The larger Craftsman is actually a re-badged Fluke 15b. I believe the small Craftsman are actually made by Extech.

After reading some of the threads here, I'd like to get an Amprobe 270. Notice the red theme continuing, hmmm?

[Edit to add - It's not that I'm a die-hard Craftsman fan, but I couldn't resist when I saw those going for dirt-cheap on flea-bay a few years ago. I didn't know nearly as much about electronics or meters back then, but in hind-sight I'm satisfied with the purchases.  And, I did just order an Amprobe 530, it has the features I wanted, non-contact voltage, capacitance and temperature probe for about $42.50.]

And a DMM embedded in the 4-in-1 signal generator - frequency counter - power suply - multimeter unit MS-9150 from Metex
(this one suffers from the slow continuity test beep syndrom, but measurements are accurate and I like its mmory and min/max capabilities)

Yep, that correct, it is a funny thing, nice lensed led dsplay in a purple color but a bit crapy build. Feels like when you drop it it will not survive and if you plug a banana in, you think it will come out on the other side. And it is hilarious to see that housing from the inside, they just took a calculator and hobbyed a multimeer in it.
Title: Re: Show your Multimeter!
Post by: G7PSK on November 09, 2012, 10:50:37 pm
I think that is exactly what they did, had surplus cases from the Sinclair calculator and put the meter into it. The switch slot looks like they just put a saw through the keyboard.
But that was Sinclair all over, use what ever was cheap and at hand, i grew up in Cambridge and met Clive Sinclair a couple of times when returning faulty goods, I found that about one in five units would work correctly when buying his audio amplifiers, he was getting the reject transistors from a company called Newmarket Transistors which were also in Cambridge and making his amplifier modules and the micro radio from the ones he could coax to work.

Capable of tube matching and tube "rejuvenating"
Also the first Dim Bulb Tester (lamp in series to take the current in case of a short)
All in a nice portable case for the serviceman with lots of room for tubes (the first tube caddy?), and compartments for adapters, and tools.

My current collection in purchase history order from left to right. The Fluke 87V on the right speaks for itself and is worth the $ spend of you can afford it. The Triplett 2202 has remained the most used meter because it is accurate (though not with high precision) small, stable on its tilting bail and has a better display than even the Fluke. The Radio Shack I bought because it was the first one I'd seen with logging software although I've never used the capability. It's an inaccurate PoS and the probe connections are completely useless. The Digitech analog was purchased to measure pulses and replaced a similarly cheap analog meter that broke after 10 years. I would not recommend it at all but I needed the pulse capability on a Sunday afternoon, the supplied probes broke within 2 uses and it won't accept any shrouded plugs.

Title: Re: Show your Multimeter!
Post by: PA4TIM on December 07, 2012, 06:00:29 pm
I do not know anymore, those AVOs are only to calibrate by replacing parts. My own AVO 8 is also not very accurate ( except for current) but within specs. But most analoge meters are not great in accuracy if you are used to 6,5 digit meters  :-DD

The meter is braille and my friend is blind so precision is no point. You measure, then clamp the meter by moving the lever to the right until you feel the resistance from the needle ( very clever made). Then he reads with fingers the value so that is not even close to reading it using the knife needle and mirror scale. So i did not bother to calibrate it. It was good enough for the purpose and on most ranges within or close to specs.

3. VC99, bought these two off eBay too. Both work fine for my hobbyist needs, £50 for both VC97 and 99.
4. DT-830B, I knew it was gonna be a piece of crap, but I still bought it to find out 'how bad can a dirt cheap DMM be', this one was £4.99 free post. It was CRAP, I had to ditch the test probes and solder a pair of leads to it -  the sockets have a thick layer of oxidised copper and the probes were flimsy. Well, for less than a fiver, I can't ask for too much.

I have a U4341 too, I think they are a Russian copy of an Unigor. A friend gave it to me, he had not used it over 25 years, it was in his barn and the foamstrips in the metal box where desintegrated and so was most of the paint of the meter cabinet. It works but it is by far the worst analog meter of my collection. It has a transitor test function I think that was not very common in those days.

This is my Unigor, very good meters. I like the simpson 260M more but the Unigor is great too.

The AVO and peak test meters are the only ones that have not disappointed me at some time, but all of them are good in their own fashion, I just had a look at the batteries in the insulation tester, they were Duracell plus with an expiry date of  March 2010, so I changed all 8 of them they still powered the meter and none of them had leaked but just to be safe I binned them.

I have wanted to post in this thread for a few weeks now, but haven't taken pics of my equipment until now. It's nothing fancy but I'm proud of them because they're a bit out of the ordinary. The analog is a cheapy kit that I got when I went to a trade school for about a week and a half.

(http://i958.photobucket.com/albums/ae70/zaraak/Equipment/DSC00352.jpg)

Me too I have that DM-10 on the left handside, that I must have bought in 1987/88/89. It has some dark mark inside the rotary switch, as it had an "accident" one day. I don't remember any more what type of accident it was though. Now it is the worst of my multimeters after my UNI-T UT-33A. I have adjusted the pot inside to get its last digit match the Fluke 87V reading:)

Nice meters guys, I'd love get something precision as you have there :-+

Now these three aren't mine, just what I can use at work:

(http://i.imgur.com/bfnyph.jpg) (http://i.imgur.com/bfnyp.jpg)

New Agilent U1232A, almost year old Brymen BM867 and about 4 year old Fluke 117. The BM867 still remains the only one who can accurately measure mA currents, which is ultimately the reason my employer bought it, although I really wanted it for the 500 000 count mode but we don't really need such precision around here. :-DMM

The new U1232A brings some interesting features, currently I love the tone option of low resistance beeper, it works on diode range too. What it does is it beeps at various frequencies depending on the resistance value or voltage drop of diode. When you try shorting the probes and opening quickly it generates sounds like some old 8-bit game console :-DD

edit: I forgot to add a bit about the probes. Those which came with the Fluke aren't really durable for daily use. We have 4 of them here and all of them sooner or later started to break up, I think all in the same place which is at top of the probe as the wire goes out. I guess the strain relief is not really working. You can just chop them off and use the cable for something else like small hooks for example, because the cable itself is good and has silicone coating. Few weeks ago we were shopping for some better replacement and found the convertibles TL175. They are really good, hopefully they will last longer. I think they're worth the higher price. Don't forget to get the version with screw on bannanas, for my work they are essential. BM867 came with some cheaply looking altough 1 kV CAT IV rated probes. I don't like them much so I rather got some generic UNI-T which you can see in the photo. U1232A came with more stiff probes, end is similar to the Brymen's, I guess that's for the CAT IV rating. Nice thing is they come with rubber protections ends for both sides. They also have isolation inside for the jack to multimeter so accidental unplugging from meter when still measuring something live should be a bit safer. I rate them above the UNI-T's but not as good as any of the Fluke's.

I added the specs to it. It is an odd type of standard. I never opened it but still was planning to check it and clean it one of these days, it is not bad, deviation is under 10 uV at 10V so that is 1 ppm( i normaly use my Fluke 332 for serious calibration, this one is very handy for quick checks and i use it as a precision current source in experiments)  I looked quick through the manual but I can not find a reference. It makes a pcm signal and that is converted to DC, i found a 10 MHz oscillator and i think it does a FV conversion. Could that xtal be the reference ?
I will study the manual this week ( few hundered pages)

I searched for a Fluke 8508A but could not find one.Today I wrote to Fluke if there is a chance to still get one.
here is the link I used

To my surprise I got the answer from the suggested Fluke Seller (just hit "Suchen" in the link)  that the Fluke-8508A is still produced and can be offered.

Can anyone confirm this?

Post by: Andrewausfa on January 26, 2013, 01:54:31 am
I bet no-one has seen these meters on here before....

These are UK military type 'Multimeter Electronic CT471' from the mid-1960's. These are tranistorised and work from 3 x 1.5V 'D' cells and can take voltage measurements at frequencies up to 1000 MHz. The one on the right (or the middle meter) is the CT471C with a centre zero facility. I've stuck an AVO meter in for scale but for those unfamiliar with that meter, the CT471 stands about 10 inches high. There's a lid that clips on front that holds the leads and four RF probes - one of which is in the photo.

Inside these are of a bygone age really, all point to point wired and laced cabling. Must have cost a fortune. Lovely.

I should add they weigh about 11 pounds (or just under 5kg) each.

Lovely! Another piece of no expense spared kit!  AVO built a meter to the same contract as the CT471 but I've not seen one in good enough condition to warrant buying it. I do like working with (and on) these older meters. I work with old valve (tube) radios where most of the measurements in the service sheets were taken by AVOs etc so absolute precision in a meter is not needed. That said these are remarkably good for something as old as me.

My new 6 digit voltmeter.
Is there someone who knows more about is. It has not a moving coil meter ( i do not know the englisch term, it is sort of thermic, there ia a coil or resistancewire, I think this heats the circulair formed strip and the shaft is connected to the end of that iron strip, if the strip heats it expands and moves the shaft ( in Dutch weekijzeren kern meter or 1:1 translated weak-ironcore meter)
It draws about 300 mA at 6V.
I think they are used automotive to test batteries. I think it is from the 1920's. There is no brandname on it. The back opens if you push the top and the test wire is spooled on a reel in there to store it.
Resistance wire and test wire is cotton isolated, no rubber or so.

Title: Re: Show your Multimeter!
Post by: G7PSK on February 16, 2013, 07:50:18 pm
That's a hot wire meter, the wire is tensioned by a spring and when a current passes though it the wire expands and moves the needle. I had one once but I knocked it and the wire broke due to embrittlement from age and heating.

I have a 179 and can speak for its ruggedness and real attention to detail - check  this teardown and reviews (https://www.eevblog.com/forum/reviews/fluke-179-teardown-photos/). My biggest concern about the U1272 is the prominent rotary switch, which reduces its ruggedness when compared to the Flukes you mentioned.

More bakelite and leather. Found these old GE AP-9 and DP-9 meters at an antique radio show over the weekend. Do they count as "multimeters" if you keep them together? Notice on the AC meter, the non-linear scale optimizes resolution for the mid range. It's logarithmic below and compressed above. How they do that?

The seller told me that they were used as calibration references for Simpsons in a production environment, which sounds a little far-fetched, but it's a good story. The calibration stickers are dated 1997, and both meters tested well.

Non linear scales are most times a mechanism as in my pocketwatch voltmeter. They have no plus or minus.

The older displays are angled toward the camera slightly so they aren't as different as they appear in the photo although the older ones are still easier to read.  Sill I don't have any trouble reading the newer display on the 87V.  Besides, it's got more digits.  :-+

The story my meters is woven into me getting into the EEVBlog. A year ago I was looking into buying a multimeter, thus I went to google for reviews and topics on how to choose one. That led me to Dave's teardown video's, and soon after into the PSU design series. Hardly two weeks later I was watching all his video's from #1 to the current. In the mean time I had decided on the U1272A and went to buy it via my university with an education discount.

Now a year later I'm almost daily visitin the forum for a read and the occasional post. Also I got some designing of my own started outside my (EE) university projects. So I needed a bench PSU. After comparing a lot of mid- and high end units (thanks to many topics here) I settled on the HP/Agilent E3610A, and guess what? Promotion time: I got another U1272A with the power supply. So two quality meters on my bench: I'm a happy man :-DMM

Our lab got Fluke 233 meters with the wireless display up to like 20 feet (or something)....  Well, I don't like them.  The batteries in the display die pretty fast (couple of months) and the refresh rate of the display seem to be slow at times... I just want a reliable Fluke meter that doesn't kill the batteries... I think the 233 is more like an electrician's meter with fancy bells and gadgets ... As an engineer, it's not an efficient design..

The big one costed about € 8 and the small about €11

you need different equipment to measure those voltages. I recommend putting some wire into the handle of a beer mug or such and calling your friends.

I think it should be fine for lower and medium voltages, and as discussed in the Test Equipment board, it's quite accurate.

I bought 2 from Frankie, biggest wait was my postal service ( apparently they are on strike, haven't noticed any difference though) to get them to me. I like them a lot, even though one was a give away item. Having a draw at mt local ham club with it, good way to get the funds in, as only paid up members can enter. I will even enter, who knows, I will ask for a redraw if I come up.

Post by: RedGrittyBrick on April 01, 2013, 06:37:23 pm
I'm only a hobbyist so don't really need good meters, I've accumulated some junk over the years.
Left to right, back row first:

Fluke 25 bought recently on eBay. Does microAmps, basic accuracy 0.1%
Velleman HPS5 personal scope. Only good for basic one-channel low-frequenct signals.
Fluke 77-IV. Not True-RMS. The 177 is a better buy. No microAmps, only high capacitance.
Laser 3534. Cheap, inherited. I keep it in the car.
Caltek CM1200. Cheap used to be my main/only meter for many years
Draper DMM7, Cheap, inherited. Unreliable.

The Fluke 25 is an ancient ex-military unit, very battered and a bit fragile. The circuit board is marked "Copyright 1984". The main chip is marked "10 88" so perhaps manufactured in 1988, 25 years old. Last calibrated in March 2009 and still within specification so far as I can tell (using 0.1% resistors and voltage ref). Although less beat up models have come up on eBay I still feel it was a good buy and useful for microamp measurements.

The 77-IV, also recent buy on eBay, was dirty but cleaned up OK (detergent.  finally a bit of IPA on a cloth). It's a current model but I paid a quarter of the price charged for the new product. However it's an overpriced meter. The 177 is a much better buy and is very similar (but True-RMS and better accuracy and cheaper new). This is now my main meter.

Latest addition to my collection:
Hioki 3200-50 all the way from 1984. AC modes seem flaky, everything else is still right on. And love the neon lamp to the left of display to show overvoltage.
Runs on 2 AAs and claims 500 hours of battery life
Other notable things- 1G input resistance on 200mV range, 20uA current range with 10nA resolution.
Oh, and designed to survive a 1meter drop on concrete floor with no rubberized case ;)

I previously only had some cheap manual ranging junk meters. I was thinking of buying an UT61E or a fluke 17B, but then i came across this 8860A.
It is an overkill just for my hobby needs, but was in good condition and cheap at local auction site.
i paid only 25€ for it and it came with a 1120A GPIB adapter. Only disadvance is that it doesen't measure current, but i can just get a good shunt to fix that.

Here's one that has been with me since the early eighties. It's a Unigor 6e and while it doesn't get much use nowadays it can't be beat when it comes to measuring very low voltages or currents.

1 mV and 1µA full scales it what's makin it, and on top of that a low burden voltage!

Post by: Robomeds on June 15, 2013, 05:18:00 pm
Adding to the fun... and copying the stairs shot... though not as effectively. 

Here is the short term collection.  A number of the Flukes are going to be going away.

Top row:  Fluke models 113, 77-3 (Lincoln Tech), 87-3, Matco MD87S3, 88-V, 8100B
Bottom: Cheap pocket thing, Harbor Freight cheapie, BK Precision 8360, Agilent 1241B, pocket Radio Shack model, Fluke 8025B, Sperry DM6600, Fluke 97.

I bought the 113 used before I realized it really was worthless for anything other than home wiring testing. 

The 77-3 was a gift from a friend after he finished his tech school hence the reason why it has a trade school name on the front. 

The 87-3 was a great ebay find.  $50!  Of course that price went up 40% when I found that one fuse was blown. 

The MD87S3 is guess what... an 87-3 with Matco labeling.  Because it's "not" an 87 it didn't command 87 prices. 

The 8100B was purchased because I thought I might harvest the nixe tubes.  I don't think I will so it will probably be sold.  Amazingly it seems to match the 87 readings when testing batteries. 

The first pocket thing was bought in a box of 12 for something like $30.  I've been giving them away over the years.  I also leave on in the car just in case. 

The HF was "purchased" with a Free With Any Purchase coupon.  I think it and the air fitting cost me less than $1.  All I can say is the meter meets it's loose specs but I wouldn't trust it with any high power or high voltage circuits. 

The BK 5360 is a made in France Metrix MX58 under the skin.  I learned that thanks to one of Dave's videos.  I had always been intrigued by it.  I paid perhaps $45 for the thing in new condition.  At first I figured it was a off brand BK labeled their own.  Only the made in France part caught my attention.  50,000 count but "just" 0.1% accuracy.  The probes feel cheaper than the rest of the meter.  I leave this meter at work since it won't be confused with the Flukes in the lab.

The Agilent was a recent find.  Seemed like a good price even though it offers little over my 87-3. 

The pocket RS thing was my first meter bought probably in 1990 or so.  Still works but gets basically no use. 

The Fluke 8025B was a steal at under $20!  It's clearly seen some use but nothing too bad.  I know Dave said these were big but I don't think he did it justice!  It's twice as thick as the 77-3 (sans case).  I look at the thing and think it's an oversized prop!

The Sperry is a low end model.  Slow and of little merit.  It does at least have ceramic fuses. 

The 97 Scopemeter was my first scope but has recently been replaced.  It looks multimeter like so I included it. 

Most of the flukes will be gone to new homes soon.  I was asked to keep an eye out for a few friends so they will have those meters soon.  Between the cheapies and the 87-3, 8025B, Agilent and BK I figure I have enough :D

I started with a "VEB Meßtechnik Mellenbach/Thüringen Vielfachmesser" that I was gives by the father of a friend of mine together with my first tube amp. It's the same model as shown here:

(http://images3.okr.ro/serve/auctions.v7/2012-06-25-624629dc6f6b97bd21c442da8ddf8ac2-117120-700_700.jpg)

Later I bought a Metex M-3800, nothing special but it was enough for a few years, cause I could use the Keithley 2002, the Prema 5017 and the 34401A at work. Since a few days I have a Prema 5000, it's not a beauty but hey, who cares? It's case is made off solid aluminium, not that sheet metal and plastic stuff off todays instruments. Payed 300,-€ for that gear and it seems to be within spec, but I will check that in detail after the gear at work has been calibrated the next weeks. Therefor I will check the ranges with some good old Burster DC-Standards Typ 3401 / Typ 6401 and a Precision current source Typ 6424.
What is still missing is a decade resistor calibrator, maybe I will buy a few Vishay z-foil of different values and check them at the Keithley 2002 to calibrate my Prema 5000.

By the way, have you ever seen such a beauty?

@Fezder, I don’t use them all ofc :D It is more of a collection than for use, mostly I use the Fluke 85’s and 87. Sometimes I use the Extech if I need more resolution. It just depends what I have to measure.

This is my main one, I've had it for almost 15 years now? It was sold by Radio Shack and I bought it for about $90 at the time but is apparently made by METEX, but also sold under the Voltcraft name as well.

I found this picture online, mine's not as in good condition, the battery compartment door got lost some time ago and the battery holder broke and had to be rewired, but other than that still works.

The closest looking METEX meter I could find claims True RMS but there are no such claims made on mine.

Haha, i have also that bad habit, or dirt cheap prices either, well, what wallet can afford that is....but i just keep collecting ''junk'' last time i got about 300pcs of 1kv/100n caps, but i dont slightest idea what to do with them :D
Title: Re: Show your Multimeter!
Post by: SeanB on June 23, 2013, 09:40:53 am
Easy to use those caps, place inside each plugtop as IS capacitors. Will do a lot to reduce mains noise. I bought a whole box ( 2000 units) of class X2 0.22uF 250VAC capacitors on auction once, for about $1. Been using them for that, and there are a few motors where the capacitors failed that have 20 or so in parallel inside as replacements.

As well I bought 2 boxes of zener diodes, been using them as signal diodes for years, still have not made much of a dent on the 40k of diodes. 12V 400mW and 24V 400mW zeners I now never buy. I was asked for some 13V ones, so gave a box and told them to use 2 in series to increase the voltage by 1V2, even did a quick demo there and then with a PSU, diodes and a random resistor using a DMM to show how.

I made a trip to my hometown to visit my parents last weekend, and I found this meter calling my name in a pawn shop.  I guess it wanted to be with a few of its siblings.  It's in like new condition, despite being over 30 years old.

You know what will happen some dark and stormy night? All your fluke multimeters will rise, steal all the batteries in your house, and then go on a road trip to visit John Fluke's grave. Be prepared, and don't have a cheapy $5 meter block their way.

"The night of the living Flukes!"  - coming soon, direct to late night broadcast TV on an old, analog, low power TV station.

I need to count them all.  More importantly, I need to confirm that the batteries are gone from the ones I don't use.  Amazingly, the 30 year old meter still had it's 35 year old battery, and it didn't leak!

I want to get a cabinet similar to the ones I have for my camera collection for the meters, but I've got a bad case of procrastinitis.

I went through all my equipment and pulled anything with Duracells as they have been the worst leaking POS batteries the past couple of years.  Anything I don't use on a regular basis only gets batteries when needed and anything used occasionally gets Energizers now as I've had little trouble with them leaking.
Title: Re: Show your Multimeter!
Post by: SeanB on June 28, 2013, 06:44:55 pm
You are having better luck with the energisers then. i have had plenty leak. The good thing about the 9V alkaline cells is the double layer of protection, though the 9V Eveready regular cells have a nearly dry paste which does not leak even if left for ages.
Title: Re: Show your Multimeter!
Post by: SLJ on June 28, 2013, 10:50:40 pm
I've been using the Energizers with the 10 year shelf life.  Don't know if that makes any difference as far as their case leaking or not. The Duracells have been a disaster though the past couple of years.

Hi

I  digged out my first multimeter,a EICO TRUVOHM Model 20A3
It was a present from my father and theres a lot of memories connected.
Anyway I took off the back to put in new batteries and the pics tells the rest (it was stored for around 25 years w. batteries).
A good cleaning off the goof and new batteries,now testing !?... yes it works !!! (allmost crying now)
Its proberlyy nostalgia but I gets this warm and cozy feeling when using analog meters.

Nice.  My first meter was an EICO - I still love the analog meters.  My Eico was a clone of the Simpson 260 (the first one, not the more rounded ones from the second series up to the present) 

My 77 was in the 30-50 dollar range, about what I think they should go for, less shipping.  I consider that a holster is worth 20 dollars in like new condition, and worth almost nothing in dirty, beat up, nasty condition.

Today I received a brand new (but of course from old stock) Fluke 27 and I must say this is really a great, robust and perfectly accurate meter.
I tested it in all functions and ranges and it was perfectly linear and spot on.
Because I have my own cal lab, I did a full calibration ckeck: DCV, DCI and Ohms max. 1 count off, ACV and ACI at 50Hz mostly max. 1-2 count off
Very amazing!!!
This will become my new main every day tool, also because of 1000h battery life!

Don't think so if you take all of that gear separately:

V/I source ~ 2K
DMM ~ 1K
electronic load ~ 1 K
power supply ~ 0.5 K (or more)
Sc tracer instrument ?? (can't extimate)

+TAX = more than 5.6K, The 2450 is 5K taxed, so it's a deal.  :)

Thank you for the flowers.
 
Yep, the wooden box is beautiful, but that's only a saturated cell without temperature stabilization. You need a thermometer sticking inside to calculate the 20°C voltage.
It's simply a museums piece (like me  :palm:).

I used the 7135 datasheet standard circuitry, with a polypropylene 470nF foil cap.
The reference is an ICL8069A, 10ppm/K.

The resistor assembly is sort of free wire connection on the switch, so really nothing to share.  ::)

The 4 1/2 digit module also contains the ICL 7650.

If you're interested, I could search for the old layout I think I've still saved somewhere.

Uh, there's nothing mystic about that.

The module measures voltages of 2V, 200mV and 20mV only.

In current mode, I simply used decade shunt resistors from 0.1 to 10k, and the 7650 amplifies the voltage over them by a fixed factor of 10, i.e. 200mV max. burden. That's all.

Hello.

I bought a cheap DSO few months ago and got a Sanwa PC5000a DMM for almost free in some special offer. I would really recommend this DMM. Solid, fast and precise. Extreme difference after switching from some cheap Chinese crap ;-).

As far as I've seen I'm in the minority here with an analog multimeter. This was my father's before he finally got himself a digital meter and gave this one to me.
I have the exact same meter. I think it cost ~$10 about 20 years ago. It lives at my mom's house for whenever she needs me to fix things around the house :)

My main meter now is a Fluke 189 though.

Not a DMM, but measures multiple voltages.. a powersupplay tester for computer PSU`s.. handy to test  ATX . BTX and ITX  PSu`s,
20/24 pin ( ATX - connector )
Voltage test : +12V , -12V , +5V , -5V , +3.3V , +5V Stand by (SB) 12V power Good ( PG ) Connectors : Floppy, HDD , CDROM , SATA , 4pin ( P4 ) , 8pin ( Dual-CPU ) , 6pin ( PCI-Express )

Connect it to the PSU and it starts the PSU automaticaly.

Cost under a 10$, but worth the money if you have a lot of PC repairs..

Nice tool, I have one. It's nice for quick testing but it does not have some dummy load. It would be great if it had. Sometimes all the voltages are there but they go down or completely disappear on load.

OK, I'll do this one too... ;D

My favorite general-purpose meter is my Heathkit IM-11 analog volt/ohmmeter. The reading is amplified by a vacuum tube so it has a nice 11 Mohm input impedance. I've modified it: replaced the 1/4" phone jack with bananas, separated the common input from the chassis (yeah, somebody at Heath actually thought connecting common to chassis was a good idea on a non-earthed meter :palm:), earthed the chassis (the damn thing radiated 60 Hz like nothing else), replaced the old, drifting resistors in the voltage divider, and replaced the D cell (for resistance measurements) with an LM2575-based battery eliminator. (Yep, it really will pump 100mA into a low resistance, and I didn't feel like setting up a heat sink for an LM317...)

For more precise measurements, I use my Fluke 8600A. I love the LED display, very easy to read no matter how tired my eyes are. Autoranging, too, though I don't use that much.

No, just annoying to use and overkill for most purposes. I still use it when I need it - the extreme (for me, at least) precision and recently calibrated accuracy are handy sometimes. I use it as a reference to adjust other meters.

The white plastic under the 8600A in that picture is the top of the 3468A.

Hi,

after a few years of ebay, dumpster-diving I used to own several Multimeters.
A had some cheap crap I donated to people I didn't really like and some good ones (two Fluke 8600, Kithley 179, some other Fluke) I gave to people I did like ;) or donated it for our Ham-Club-Station.

The ones that are in my posession right now:
HP 3478A
Philips PM 2524 (my first Benchtop)
Prema 6001 (I'm sure no one knows them, but they made really highest Quality stuff)

"Voltcraft" M-4660M (that was my first MM)
Tektronix DMM912 (whoever produced this...)
Gossen 22S (my mostly used one, got it damaged and repaired it)

They're ok for typical battery / ATX PSU voltages. I wouldn't use them for anything requiring high precision, or >100V (including mains voltages).

I recommend them a lot for non-EEs. I get a lot of people who get really weird readings for their computer PSU voltage from some crappy software or their BIOS; I tell them to get a $10 DMM to check and make sure, since software voltage measurement on computers is laughably bad.

In my experience, they're usually within +/-0.5% of my Fluke 87 V at ATX voltages.

I don't think so.  As Dave would say, ". . . they will blow your fucking hand off . . ."
If Dave can come up with a good multi-multimeter test to destruction idea I will send them to him.

As for the Weston's they are all functional and I have used a few for battery/capacitor monitoring/discharge experiments, the Simpson 260 works great and us it all the time on vacuum tube radios, and the three Hickok's is mechanically good but the wiring and some components need repair/replacing.

For low voltage measurements that don't need high accuracy, sure IMHO. Could be useful in a car glove box to check for voltage on the side of the road for example.

Could also be useful as V & A meters on a DIY PSU that's not high voltage or current as well (say 30V, 5A max). Particularly if they were free.  :o  :P

Those Hickok 209A's are a sight to see. I love the large meter.  I prefer the looks of the black face one over the silver one.  Rebuilt one a couple of years ago but did not have room for it on the bench. Most likely will pick up another at a swap meet at some point.

You are absolutely right echen1024.  I was being a bit glib.  I have built a couple of battery charges and used the LCD and associated innards for the volt and amp displays.

Yes,  It's in the collection.   I got at an estate sale with a bunch of other tubes I purchased. Since it's full of mercury there's not really much I can do with it.  Can't really ship it easily and items containing mercury are not usually allowed at swap meets so I guess it stays.  It's pretty large.  One of my winter projects is to build a stable display stand for it so the cats can't knock it over.

Time to show the shame (THE SHAME) in the multimeters that I own.  :'(

The analogue meter is a digitech cheapy from jaycar, which I got roughly a year ago, after a University course demanded an analogue meter.  :palm: Not too bad for $20.

The DMM is also a cheapy, however it originates from Dick Smith Electronics, back when they actually used to sell electronics parts in the store (probably around 8 yrs old at least). Ironically it is not branded at all (who would on such a piece of crap). As you can see, it is a little  ::) worse for wear, the centre plastic support has completely broken off, and the common terminal will not be far behind. As to the meter's accuracy, who gives a damn, I am sure it is no-where near accurate.

And holy crap, just pulled the thing open, and found a model number, apparantly it is a UNI-T UT30B. Not sure how I feel about the UNI-T brand now... If anyone wants to see the horror pictures from inside I'll open it up and get some pics for you.

Here's to hoping I win one of the multimeters in the contest, short of that I'll be heading out to replace these meters with something more respectable.  :-+

As a bonus you can also see the 100% quality test leads that I am using with the meters.

Can you tell me more about this meter, google is not helping.

You can download the operating and service manual for the 3450B from Aglient: http://cp.literature.agilent.com/litweb/pdf/03450-90007.pdf (http://cp.literature.agilent.com/litweb/pdf/03450-90007.pdf). It should similar to the 3450A.

Specs (3450B):
5½ digits (120000 counts) nixie display
VDC: 100mV .. 1000V ranges, 1uV resolution, 80ppm + 40ppm FS accuracy (90 days)
VAC: 1V .. 1000V ranges, 10uV resolution, 400ppm + 100pm FS accuracy (90 days)
Ohm: 100 ohm .. 10M ohm ranges, 1m ohm resolution, 100ppm + 40ppm FS accuracy (90 days)
Up to 15 readings/s
Autoranging
Autozeroing
Ratio mode for VDC:VDC, VAC:VAC and ohm:ohm
Limit test (LO, GO, HI)
Digital output (BCD encoded)
Remote control
Rear input

On of the first HP DMMs with a dual slope ADC. It uses tons of diode-transistor-logic (DTL) ICs. A predecessor of TTL. The highest integration once are 4 bit BCD counters. The reference zener and the first stage dual jfets of three amplifiers are thermal stabilizer by a peltier element. It uses a thermotransfer True-RMS converter. This works with a heater-thermocouple combination and adjusting a DC voltage until it has the same heating as the AC voltage.

A very sophisticated instrument for it's time.

The YellowCaltek Unopened Analog Multimeter was to replace the one lying down because the contacts snapped inside it and was unrepairable, The Rapid Electronics Analog meter i got for £2 brand new unopened off Ebay it is such good quality i bought another one off the same seller as a spare, it is unopened in the Box beneath it.
The Two Draper meters are both faulty.

Nice, we haven't seen too many electrometers on here yet. I'm surprised Dave hasn't acquired one yet given his interest in low currents. Electrometers are more versatile and capable than the Keithley 480 picoammeter that he 'repaired' a whille ago. I think this one goes down to 10 fA full scale? Eventually Dave will do an episode on one and everyone and their dog will suddenly buy one, just like the rubidium frequency references ;).

This one mostly came from eBay--priced right because the meter glass was broken. I had another one (a quite dead rack mount version with glass intact) and was able to swap meter faces. It worked! It was easy to bring into calibration but I've not yet plumbed the extremes. The lowest full scale ammeter reads 10 pA, but with the 0.001 multiplier, yes, it goes down to 10 fA full scale. That's 100 aA resolution, in theory anyway.

There's a lot of interesting theory wrapped up in these old instruments, so I do hope that Dave gets his hands on some and does a "Teardown Tuesday/Fundamental Friday" on it when he's worked through his current repair backlog!

This is my lot of meters. L->R is a QM1566 from jaycar bought about 3 years ago. Accuracy is OK, but the great thing is it can measure lots of DC current. Next is an Agilent U1252A, bought from TrioSmartcal on special about a year ago. Next is an Agilent U1241A also from Trio and on special (notice a pattern forming here, I'm a regular tight a$$) Above them is a rigol DM3068 bench meter (i dont use as much as I should). and finally a 10+ year old peice of crap from Jaycar QM1320( I have 2), the price was right at the time and served their purpose, but glad I haven't measured anything higher than 240VAC with them. They've pretty much been retired now. I mostly use the U1241A but switching to measure voltage is annoying when it's defaulting to measure ACV.

I own U1242B which I believe very similar to U1241A, just read the manual, you can set the voltage defaulting to DCV.  ;)

My good old trusty Fluke from way back.  I used the original probes on them until last week.  I finally bent one and replaced them with Pomona probes.  I used to use this at one of my first engineering jobs.  I don't quite remember all of the details why someone wrote that on the meter, but I'm certain I earned that name.

It was easy to bring into calibration but I've not yet plumbed the extremes.
Fortunately calibrating/adjusting these doesn't usually involve accurate 10 fA current sources or 100 Tohm resistors.

The lowest full scale ammeter reads 10 pA, but with the 0.001 multiplier, yes, it goes down to 10 fA full scale. That's 100 aA resolution, in theory anyway.
Or about 600 electrons/s ;). Measuring that is more like experimental physics than electronics, though.

There's a lot of interesting theory wrapped up in these old instruments, so I do hope that Dave gets his hands on some and does a "Teardown Tuesday/Fundamental Friday" on it when he's worked through his current repair backlog!
Agreed.

No, I don't own any Flukes, all my DMM's are Chinese/Taiwanese made. I have so many simply because I'm both a hobbyist and a seller, and that gives me a very good excuse to spend money on DMM's I don't need but "might" be interesting to have a look at  >:D

The ones that are not in the picture include those at home (Brymen 867 and 257, and a couple other Digiteks), an HP3457A bench meter, and a few others that I rarely even touch anymore, hence not worth the bench space and have been put away.

Don't laugh guys, it's all I can afford right now.  I am eyeing an Agilent or a Fluke, once I get some income..

It says it's automotive, but that's just because it has an inductor for spark plug wires to show RPM's and dwell angles.  It actually works decent, compared to a friends fluke, it was actually pretty spot on which surprised me.  But for voltages above 600v, I wouldn't trust it.  It says CAT II 600v, then says it handle 750v AC and 1000v DC?  Um, ok..  lol

Here is most of my collection, there's also a cheap analog meter that I'm not sure even works anymore that I am not including and I'm sure if I look hard enough I'll find at least one more.

I've had the Fluke the longest, it was old when I got it, 12 years ago or so, it's been well (ab)used.

Two differential voltmeters: the Fluke 887A (AC/DC) and Fluke 895A (DC only).

Both are specified at 25ppm accuracy on DC ranges. The difference is the 895A has infinite input impedance at balance on all ranges, whereas the 887A presents 10M input impedance on the 100V and 1000V ranges.

The pictures demonstrate the difference. The 895A (on the right) is measuring a 10V voltage source directly. The 887A (on the left) is measuring the same voltage source, but in series with a nominal 10M resistor.

On the 10V range, they measure the same (well, 10.00035 on the 887A and 10.00000 on the 895A -- that's as close as I could match them during calibration).

On the 100V range, however, the 887A reads 4.9978 -- it's neatly divided the voltage in half with the 10M series resistor.

Those are two interesting pieces of equiptment. I assume you have them referenced to an external source, or do they have their own intetnal one. Is the ac/dc a thermal rms converter.

Both contain temp-compensated zener diodes for internal reference voltages. The DC-only version has inputs on the back so you can connect an external reference to the KV divider inside. The AC/DC version is average responding. There's yet another model (the 931A/B) that measures RMS using a thermal converter.

All of these are plentiful on eBay, with gigantic price gaps between the clean/tested ones and the junky ones that need a bath and a tune up.

(https://www.eevblog.com/forum/chat/show-your-multimeter!/?action=dlattach;attach=67734;image)

Back row: Weston 7320, Weston 6100 "Roadrunner", Beckman 3020
Front row: Fluke 8020A, Beckman RMS225

All are made in USA circa 1980 except for the RMS225, which is more like 1990-ish.  I couldn't afford these when they were new, so they are all recent acquisitions.  The 8020A and 3020 required repairs, but all are functional.

I made a little gray and yellow sculpture for you.  A few needed repairs, but a bottle of IPA and some fusible resistors takes care of most problems.  I fibbed earlier, I did save my pennies and buy the leftmost 87 around 1990. With an updated LCD and white backlight, it's still my favorite meter.

*snip
That is rather interesting, I forgot that average responding voltmeters can be that accurate by themselves. Then I remembered that they were almost neck and neck with your average thermal rms converter in a high end multimeter(70/80's vintage.) It is rather interesting that it seems like they used a possibly dual matched diode for this. To bad I cannot find any information on the diodes. My average responding voltmeter (Ballantine 323-07) utilizes 2 matched back diode(unitunnnel) true rf stuff these days.

Just the stacked-up ones (and the second 87) in that shot were advertised as 'broken', but when half of them end up only having dead batteries, it's not too much of an achievement to get them going again. :)  And the ones that look the least abused physically always have the best odds of success, no surprise there.

Fusible resistors open up when too much power is dissipated, preventing further damage. You will find at least one in just about every Fluke design.

My turn to show off
These are my handheld meters. Usually the two  bench ones are used the most (Fluke 8840A and 8842A), but they are not as interesting as this group. Keithley 130A, Hioki 3200,Meterman 35XP, Agilent U1252A in back row.
Front row: Sinclair PDM35, Alda M-838, Yokogawa CL-220

(http://kuzyatech.com/wp-content/uploads/2014/02/1-P2040160.jpg)
And a closeup of the more senior section. Hioki (circa 1984) is built like a tank and working well. Note that it actually has covered plugs- seems pretty rare for that era, as well as a neon overvoltage indication lamp.
 Sinclair meter is flaky (apparently as expected), and a Keithley is slightly out of cal. The Alda meter is actually from 1993, and has the worst LCD ;)

I guess it's about time I made a contribution to this thread.  I won't bore you with the gray-and-yellow meters around here.  But here are some items from Mr. Modemhead's Multimeter Museum.

Really nice seeing that Beckman multimeter there. I have the exact same model (will post a pic of my collection). The Beckman 3020 was the non-RMS model and the 3030 was the True RMS model. Fine multimeters for their day, going all the way down to a 200uA scale. One of the other features I really liked about the Beckman was that it had a 2A scale. Very nice collection.

From left to right, my collection includes two Brymen meters (BM867 and BM811), a Fluke 77, Beckman 3020 and three MajorTech models on the right. The pocket DMM (MT855) is only 10mm thick, but is extremely capable for its size - it has a frequency counter that goes op to 30MHz.

The clamp meter is a 40A-400A model which I use around the house. The orange one I bought because it was ultra-cheap and based on the Intersil ICL7106 DMM chip, an old favorite of mine.

The Fluke and the Beckman last saw calibration in 1989, but both are still spot-on. I had the two Brymens calibrated a few months ago - since I've had these, they are my go-to DMMs on the bench. Before I had them, I mainly used the Fluke and the Beckman.

The two Brymens are sold in South Africa as the TBM867 and the TBM811 respectively.

I would hope so, and wonderful that you found a used unit in such shape.  ;D

They're not that common here in the US, so used is very hard to come by IME (most is photography related, and even some PSU's <Konstanter>; currently zero Gossen DMM's listed, unless you count 1x listing for leads).  :'(

I wouldn't mind seeing those gray & yellow meters of yours, especially ones with histories where you fixed them.  :-+
I made a little gray and yellow sculpture for you.  A few needed repairs, but a bottle of IPA and some fusible resistors takes care of most problems.  I fibbed earlier, I did save my pennies and buy the leftmost 87 around 1990. With an updated LCD and white backlight, it's still my favorite meter.

Sorry for bringing up an old post, but how did you update the LCD? Replace the elastomers or use a different LCD? I couldn't find this on your blog...

Hello friend can you please try something for me?

To the Agilent 34461A

In diode mode, when checking a diode.
1. Does it continuous beep when diodes are short circuit?
2. Short beep when diode is good.

I have plans to buy this meter and I use a lot diode tests.

Here's my collection. Two Fluke 27/FMs and a Sparkfun cheapy I picked up before the Fluke/Sparkfun debacle that Dave covered in one of his videos. I recently bought the two Fluke meters, but despite their age, they still show the same reading for the few measurements I have used to compare them; although, that is not much of a surprise.

I have another DM502 which is not shown in my rather poor photo.  I have since gotten a better camera.

My most interesting multimeters are a pair of Tektronix 7D13s which use the readout of a 7000 series oscilloscope mainframe as a display.  I have more modern multimeters but they are less photogenic.

I haven't had it long, but it seems like decent quality.  I haven't opened it up, but it feels solid and has a fair bit of heft.  I don't know if Klein Tools makes it themselves or if someone else does.  It's stamped "Made in Korea" on the back.

Some of Klein's handheld multimeters are made by Fine Instruments

http://www.finest.co.kr/pi.html#hd (http://www.finest.co.kr/pi.html#hd)

Being made in Korea suggests it is also made by Fine Instruments, but I can't see anything in their website that looks like the CL2000 right now.

BTW, the UEI DL379 is identical to the CL2000 (see picture).

Those little transistor checkers are a gimmick (good way to get dust & moisture into a meter IMHO though). And the "cool expensive DMM's" such as a Fluke 287/9, usually do have a diode function (but use the banana jacks to connect up a diode via whatever test leads you have that are suitable).  ;)

Transistors behave completely different at different ibe and vce. How can a single meter be able to test all the real world usage without getting too expensive? If you can afford a tracer, go with it. If not, improvise your own testing environment. If a tool is engineered solely for one purpose, it is usually much better and cheaper, unless you are selling millions of them.
Title: Re: Show your Multimeter!
Post by: Lightages on April 28, 2015, 06:18:10 am
Transistor testing functions in a multimeter are considered a gimmick because of a number of reasons.

1. The socket needed for the transistor test brings internal voltages close to the surface of the meter casing. This is very bad practice when it comes to making a multimeter safe for high voltages and CAT ratings. You now have exposed metal contacts that could be at the potential of the whatever the test leads are connected to, especially if there is some failure inside the meter.

2. Transistor test functions on multimeters are almost always very poorly implemented and the readings are really only good for maybe a relative measurement between transistors. You don't have the full curve of the transistor's function so it will be a guess as to what the real value of the transistor is.

3. Because of the above, and because it is a cheap gimmick to add to the multimeter, it would be much better return on a design to spend the time and funds adding better safety, durability, quality, or accuracy. It is a cheap "look at all my functions" gimmick rather than something useful.

It is much better to spend the money on a dedicated transistor tester than waste money on a multimeter just because it has the transistor feature.

I see. Thanks for your explaining, it's very helpful.

I didn't understand why people was into these cheap LCR meters, I did believe that should be part of a DMM for electronics.

We newbies are easily amused by feature creep and the all-in-one obsession is very deep in our minds.

Okay, so a LCR meter is a better tool for this task. I see!

Because many DMM feature a communications port, I wonder if a LCR module would be feasible. It could make one less thing to wear and save parts such as the LCD, and provide easy sockets port putting components.

Hi

New to the forum, and this seems a quick and easy introduction. I stumbled on the EVblog some time ago and have enjoyed learning from the videos. Thought I should join the forum as I am just retired and have a number of projects to develop and will need help I am certain.

Back to the meters, several are not so well known, and all have been acquired for not much outlay, or even free, over many years. The Ecom Ex-DM 1000 and the Avometers (Avometer M3006S, EM272 and Mk 8) and the Fluke 37 are less usual, and the bench BCC Goerz Mettrawatt is old, as is the Beckman and Robin. Anyway, make of it what you will...

On the left is my first one I got as a kid from my dad. I did some projects with the boy scouts with it. Its a Hung Chang HC-213.
Next is a GB Instruments GDT-11 I got as a teenager to put together an intercom kit and trouble shoot a doorbell with.
The green one is a Greenlee DM-40 home depot special cheapo meter I use to check mains voltage at work. I also use the ohms and continuity on it.

The big yellow one on the end is what I purchased recently for $40 on ebay. Its a BK test bench 389.
I have been using it building a bunch of kits and just starting to really learn about electronics and I like it!

I have the sapiens mark 1, it has an awesome over current protection system, if it meets anything dangerous it lets out a loud howl and the main fuse stops and blows, alarms will ring and sirens will ring. It comes with two probes that are even more supple than silicone ones and both have their own hard case either side on the end. Resistance reading is not very good when used with mains items.

@Daethwish, I laughed at your last post as I recalled  one of the older and now quite conservative fellows in my radio club saying he built, tested and aligned a valve transceiver using your "Sapiens Mk 1" meter, he added he was always careful to use the back of his hand!

I've still got a couple of Keithley 2015's about, I could add those to the mix, but I'd need to buy some more leads.

My first meter was a little analog thing I got when i was 7 or something. Pretty sure I fried it rather quickly, LOL. Next came a Radio Shack meter I got in 1996 that looked an awful lot like the one at far right in this post (https://www.eevblog.com/forum/chat/show-your-multimeter!/msg169214/#msg169214), but with fewer functions. When it finally died around 2011 (battery leakage, broken detent in mode selector, and something else), a coworker got me the Mastech as a surprise gift (having not realized that my offhand comment that I wanted to get a new meter actually meant I wanted to finally get a Fluke). And finally, early this year I got the Fluke 87, after literally nearly 30 years of lusting after the Fluke meters I saw advertised in Popular Electronics and the like. And finally, I picked up the old Keithley on the Swiss local equivalent of eBay to have something that can do 4-wire ohms and whatnot.

Pic 1: Fluke 87 V, Mastech MY64 (rebadged as some European distributor), Keithley 197. It probably goes without saying which one of the bunch is my everyday meter. (In the back you can see a Rigol DS1054Z, an Ersa i-Con Nano, and a Korad KA3005P.)

Pic 2: Probes. Clockwise from top left: Fluke TL175 (showing one shroud extended, one retracted); Mastech pack-in probes; Oldaker needle tip probes included with the Radio Shack meter; Oldaker standard probes given with the used Keithley (with the finger guards hacked off... wtf?); and Fluke TL224 test leads, TL238 test probes, and AC220 alligator clips all included with the Fluke 87V/E2 kit. The TL175 are the ones I use most.

Pic 3: Closeup of probe tips. Clockwise: Fluke AC220 alligator clips, Fluke TL238 test probes, Fluke TL175 test leads, Mastech, Oldaker needle tip, Oldaker standard tip.

Pic 4: The el-cheapo SMD tweezers I got off fleabay.

But on the right is says "+V   -ohms   -A

Ohms has no polarity!  :-//

I think "+V-ohms-A" really means "+{V or ohms or A}".

"Ohms has no polarity"
If one wants to check diodes with some ohm range, one would want to know the polarity of the leads. The interesting thing is that I used to have an old DMM that had the lead polarity for the ohms reversing the red/black convention.

Yup, and if you want to light up an LED (to see if it works), besides the reverse leads, it needs to be on x1 position .

The meter on the left is a Simpson PSM-4 complete with high voltage probe, The meter works well, except on high ohms ranges since the 22.5V battery is no long available. It came to me with the cracked face. Since I have had it it has been down a flight of concrete stairs, and no additional damage was incurred. The meter to the right of that is the RCA Volt Ohmyst. well known in the repair business of years gone by, and this model was the first VTVM I used (early high school, don't ask how long ago that was ;) )

(http://i558.photobucket.com/albums/ss21/AF6LJ/Test%20Gear/IMG_0627_zpseylhvg1j.jpg) (http://s558.photobucket.com/user/AF6LJ/media/Test%20Gear/IMG_0627_zpseylhvg1j.jpg.html)
The Heathkit IM-18 is shown here, one of these was the first VTVM I owned, not this one, the one I built met its demise when it fell off a bench shelf and hit the concrete floor. On the far right you will see a DMM it's a Beckman RMS-225, Yes Beckman this one is a beta version of the meter Beckman built before they were bought out by Wavetech. Since Beckman was headquartered here in SanDiego they went looking for places their meters would see use in a less than a Lab environment, so they showed up at the two way radio shop I worked at and gave out a half dozen meters. So for six months we were visited by someone from their QA department to inspect the meters and ask how they worked. I can attest to the fact that meter has fallen off the roof of a tow truck and two trash trucks while checking antenna mounts for shorts. It was even accidentally (really) kicked across the shop floor by an installer. After the evaluation period we were given the meters.

This is the meter I built to replace my IM-18 that met it's demise. The Heath IM-5228 has been a loyal servent since the early 1980s.

We can't forget the HP-3478A that sees quite a bit of use on low volgate gear. I picked this up at a hamfest back in 2010 for $85.00US. I thought it was a decent deal, and it has served me well.

For those who are interested; the current project here is the repair of a Heathkit SB-110 six meter transceiver. It works just poorly, I have a short list of parts that need to be replaced before moving on and attempting alignment. In its day it was a first class radio for weak signal VHF work. Now it's time to put all that stuff away and get on with reading posts. :)

I recognisize that frequency counter!
(https://pmanning.smugmug.com/Electronics/Misc-test-equipment/i-tSGzNXv/0/L/IMG_8703-L.jpg)

Here are some of mine:

The 3440 that I recently re-capped and cleaned up.
(https://pmanning.smugmug.com/Electronics/Misc-test-equipment/i-ZFwTL89/0/L/IMG_8705-L.jpg)

A 3439 that worked for a bit when I first got it but then got flakey; it doubtless needs recapping at least.
(https://pmanning.smugmug.com/Electronics/Misc-test-equipment/i-KzCPHTS/0/L/IMG_8706-L.jpg)

A pair of 3470X's from eBuy; both need work (caps, etc.), but they're low on the priority list.  I need to find a manual for the display section at least, and they don't seem to come up often.
(https://pmanning.smugmug.com/Electronics/Misc-test-equipment/i-GGwwD25/0/L/IMG_8707-L.jpg)

Workhorse handhelds; the 77-II I bought new 20+ years ago now IIRC, and I snagged a pair of the 27FMs from our favorite wallet-draining website a few years back when the .mil apparently surplussed a bunch of them.  Got them for less than $50/pop with cases, leads and HV probes.  The second is squirreled away upstairs and not readily at hand.
(https://pmanning.smugmug.com/Electronics/Misc-test-equipment/i-WfksWJ7/0/L/IMG_8709-L.jpg)

The ugly looking 3490A on the bottom came from Apex Electronics; I got it when I was out that way this past August.  To my great surprise, it fired right up and is accurate to within a few mV compared to the Fluke 8845A at work.  Other than a slightly dim digit it seems pretty healthy.  The prettier one on top was bought non working for parts on the 'bay, my intent being if I can't fix it to swap enclosure parts with the working one to make it look less like it's been through the war.

(https://pmanning.smugmug.com/Electronics/Misc-test-equipment/i-wtS63ZR/0/L/IMG_2086-L.jpg)

The 3456 is another eBuy parts/not working unit I got for a song; haven't yet dug into it to asses its condition yet.  The frequency counter beneath it is another fix-it project; I think there's something amiss in the front end.
(https://pmanning.smugmug.com/Electronics/Misc-test-equipment/i-rFmWgn7/0/L/IMG_8712-L.jpg)

This pair of 3440As also came from Apex; according to their property tag stickers they were delivered to Bendix 50 years ago in August - both have asset stickers on the back dated 8/65.  I'm assuming that the caps are dried out.  The display on one counts randomly; alas the second will likely end up a parts mule as it's missing a couple of circuit boards, so I haven't powered it up or swapped boards about at this point.
(https://pmanning.smugmug.com/Electronics/Misc-test-equipment/i-xNtmRF4/0/L/IMG_8713-L.jpg)

And last but not least, another purchase from the auction site.  This is the meter I used in high school, one of the labs being to draw the damned thing along with its schematic and make up a bill of materials for it as well, with component sources and prices.  It sucked at the time, but little did I know that the knowledge would come in handy 20 years down the road.  It of course had a dead, corroded battery in it, so there's some cleaning to be done, but it otherwise works well.

I have some more old HP boat anchors that were recently acquired from an estate, but they're not yet fit for public consumption - they spent ten years in a musty basement. 

In case it wasn't evident, I have a thing for nixie displays, and to a slightly lesser extent the little dot-matrix-y LED ones HP used to use.

Here are my two multimeters. Fluke 175 and a Gossen Metrahit 14S.
They complement each other in functions, the Fluke has capacitance and frequency measurement, the Gossen temperature measurement.
One thing is missing in this combo and that's a delta function. The Gossen only has this in the low ohm range to compensate for probe lead resistance, wich is a nice feature by the way.
So one day I will upgrade to a meter that has delta, for now they do the job.

My trio. Fluke 8021B, Fluke 87, and Heathkit V-5 VTVM (Yes, it works well even though it looks battered and bruised)

Guess which one is my "go to" multimeter?

The VTVM!

-Pat

Of course it is!  :-+

It was built by my Father in 1951. He owned a TV repair shop in Howard Beach, Queens, NYC from about that time until 1955 when he joined IBM. When I was a teenager in the mid 1960's I got it out of storage plus his Heathkit O-10 Oscilloscope and at least 150 vacuum tubes. That started me on the path. To this day I still love the warm glow of vacuum tubes.

About 20 years ago I did a complete rebuild. Replaced all caps except one mica cap which tested good and replaced several carbon composition resistors that were out of spec. The 1% precision resistors in the input network were OK. I also replaced the selenium rectifier in the B+ with a silicon diode. That resulted in a slightly higher B+ voltage because the diode has less forward drop than the selenium rectifier. But it did not cause any adverse effects and the VTVM calibrated just fine.

This VTVM also has an unusual tube layout. It uses a 12AU7 twin triode and a rare “loktal” or “locktal” 7A6 twin diode. I'm surprized Heath used this 7A6 because by 1951 that tube was pretty much obsolete. If you're into antique radios you'll know that Philco was a big user of these locktal tubes in the 1940's. Perhaps Heath got a good deal on some surplus. Later models of Heath VTVM's replaced the 7A6 with a modern 6AL5 and that tube combo of 12AU7/6AL5 continued right up until Heath stopped selling VTVM kits around 1990.

I really don't use it all that much but I bring it up every once in a while and let it sit powered on for several hours and then check it's calibration. It's always within it's stated accuracy of 3% full scale on DCV. And it definitely is a blast from the past.

Those loctal tubes are notoriously long lived.

Post by: Cubdriver on October 11, 2015, 05:37:55 pm
I'm with you on the warm glow of tubes.  VLSI and surface mount technology is truly amazing when it comes to stuffing incredible capabilities into minimal space, and we'd be lost today without it, but there's just something about a well laid out chassis with a bunch of differently shaped glowing glass bottles on it.  Perhaps that you can see the active elements, and can look inside and see different structures in different types.  As wonderful as silicon is, they're still impersonal little black bugs with different numbers stamped on them.

If my recollection of what I read is correct, Philco's use of Loktals was driven in large part by their intense rivalry with RCA in the development of television and the fact that Loktals were developed by RCA's competitor Sylvania.

Not multimeter, but I have a pair of Telefunken V72 amplifiers, which came as part of a package. Nice enough if you like 34dB of gain, but otherwise not much use. they were working till I took them out of service a few years ago, must see if they still work, even with the rather hazardous single connector with mains on the one end on bare pins of the socket.

Don't know what to do with them, might have to find somebody who wants them.

As to tubes, at the Ham meet last weekend, I saw some slightly used Nuvistors, just what all the Tek fans are looking for.

I do have also two cheap 3$ meters ;)

Recently I also bought:
* HV Philips probe - PM9246
* Lutron CA-203 clamp meter


Hello.

I bought a cheap DSO few months ago and got a Sanwa PC5000a DMM for almost free in some special offer. I would really recommend this DMM. Solid, fast and precise. Extreme difference after switching from some cheap Chinese crap ;-).

oooh can I play...

Here's my unit. First multimeter, purchased from Jaycar for about $50, it's the Digitech QM1548

Beckman Industrial model 310

Nice photos Bud!

Did you know that the tilting bale is designed to be removed? You can insert it into the second set of holes for a lower tilt angle. You can also reverse it and insert it into the second set of holes, to use it as a carrying handle or for hanging.

My first DMM was a Beckman Industrial model Tech 300. The difference between it and the 310 is that the 300 doesn't have the "Insta-Ohms" quick continuity indicator, or the 10A current range, and the 300's DC volts accuracy is 0.5% instead of 0.25%. They share the same main board.

The user manual for mine covers the 300, 310 and also the 330 (which adds true RMS AC and 0.1% DCV accuracy). It includes full schematics. One difference between the 300 and 310 in the schematics is that jumper wire W1 is soldered in on the 300 but W2 is on the 310. It turns out that removing W1 and installing W2 is all that's required to enable the "Insta-Ohms" feature.  :)

The plastic "Interesting LCD holder" broke on my 300 so it no longer was able to apply the proper pressure to the zebra strip on the LCD. Fortunately, soon after it broke, a 310 they had where I worked died and I was able to take the LCD holder from it to replace mine.  :)

I bought the 300 from a friend who sold it to me cheap because the 220 ohm resistor in the precision resistor chip U1 had been damaged, resulting in the low resistance range and some others being off (by somewhere around 10%, I think). I lived with this until about 2 years ago, when I decided to replace the resistor chip with the identical one from the broken 310. However, after examining both meters and the schematics, I realised that could instead replace the 310's main board with the one from my 300 because the resistor chip is on the daughter board.

So now I have a working Tech 310 S/N 60625058 but with the main board from 300 S/N 01028044 (so possibly a little less accurate than an actual 310).  :-+
I've checked it and it appears to still read within the original accuracy specifications on all ranges.

This has been my main DMM for over 35 years, only recently being supplanted by a BK Precision 2709B.

P.S. The case of my 300 was an older design. It had a metal wire tilting bale. There was no separate battery cover; you had to remove the entire back to replace the battery or fuse. The plastic shield around the test lead plugs was a larger diameter than is now standard, so the leads won't fit into newer meters and standard shielded plugs won't fit into it.

I plugged it in expecting "magic smoke" but I was denied the excitement. It powered up with no issues. It even calibrated after a half hour warm up. I'll play with it for a while then put it back on the shelf.  :-DMM

Found this beat-up Lafayette in one of my father's toolboxes.
I suppose it was made in the 70s, in Japan, for the Lafayette Radio company (Model 99-5006) in the USA. They went bankrupt shortly thereafter (Jan 1980).
I replaced the 1% resistor on the Ohms (1x) range, which had been fried with high voltage (frequent failure). Hardly any input protection in those days. Everything works fine now, but the needle sticks a bit at times, probably due to wear on the pivots.
It can measure Ohms, DCV/ACV 1200V, DCmA 600mA and capacitance 0~0.2uF.
For capacitance measurement, one must connect a 6VAC 50/60Hz signal to the meter and the cap in series. The meter is set on the 6VAC range for a reading.

My Motley collection... A Datron 1041m (Mil version) 4.5 digit DC / AC RMS / Ohms, A 1045 DC Voltmeter and a 1030A RMS voltmeter. I haven't shown the Maplin 'White Gold WG022 handheld that hangs about the bench.

The Datrons are the predecessors to the 1061 / 1065 etc Autocal family. The things I like about them are:
- Accuracy, although they're 4 1/2 digit their DC and ohms accuracy is 0.01% + 1 digit.
- Infinitely repairable, they use standard NS linear ICs and the logic is LSTTL (socketed), no CPU, no EPROMS, no NVRAM to worry about. Of course that also means no Autocal, but all the cal pots and sequences are well labeled.
- Nice readable plasma displays, but unlike the later custom one in the 106x series these use socketed standard Sperry / Beckman SP33x and 35x series.
- Same RMS performance (same Silicon) as the 106x series.
- Fully floating 10G ohm DC inputs up to 20V (10M on 100V and 1kV ranges). Much better than meters like the Keithley 177, Soartron 7150. Input current on the 1045 is less than 20pA, the 1041 is less than 5pA.
- 5 lead resistance measurement, includes Ohms guard to compensate parasitic resistance  paths.
- 10mV range with 1uV resolution and 0.03% accuracy (DC). Often more accurate than longer scale meters with higher bottom range. Useful for implementing external current shunts with only 1 or 10mV drop (can't see the point of high voltage burden current ranges on bench meters).
- The 1030A RMS meter has fully switchable AC / DC coupling, switchable filters and bandwidth (up to 1MHz)

(https://www.eevblog.com/forum/chat/show-your-multimeter!/?action=dlattach;attach=180088;image)

These can sometimes be found really cheap on ebay, probably not very popular because there are no online manuals, something I hope to rectify some time (lots of A3 drawings to scan).

@blueskull in Australia I think you are responsible to a limited degree due to principles similar to the  "attractive nuisance". If I understand it correctly , that an object has some intrinsic attraction but has also some hidden danger.
For example if I put up a radio tower and do not put something to stop people climbing it I am partly responsible.

Funny story. Dave got one of these in the mail some time ago and it looked kind of familiar to me. I vaguely remember my father having one of these on the dinner table while attempting to fix the TV. Turns out it was the exact same model and he still had it somewhere on the attic. Now it's mine ^-^ It's still working fine and doesn't appear to be wildly out of spec. Great upgrade from the cheap 3.5 digit one I used before :)

Already ordered. Keysight has a 4 week lead time on this model, so I will not get it before I leave for home in China.

Seems like I need to put a sticker on it to prevent legal issues. It seems like many guys in my lab like to "borrow" test tools without permission if there is not a private property label on it.

@blueskull I would put a "DANGER EMITS HIGH VOLTAGE FROM LEADS" label on (which is not untrue)  and your multimeter will never go missing and you will meet safety issues! :-+
Bummer re the wait, it is a good meter. Like lots of HP Ag KS stuff.
I have started doing a bit of Nixie tube experimentation  and about to get my first tube (thermionic RF transceiver) it is really nice to be able to test leads etc with 1000V before you connect everything up in earnestness. A lot of leads etc the specifications often only tell you up to a few hundred V or so.

Willb,

That is a nice hoard collection  :D

Which is you go to meter?

I have a couple of Fluke 289, but I prefer a Fluke 189. I find the 189 is more responsive, I find there is a noticeable delay with the 289s when they are auto ranging.

My go to meter is a Beckman RMS225.  I really like the banana jack layout because I can use a standard 3/4" banana plug for the 10 amp range which very few meters can do.

The two common complaints about autoranging meters in the past when this was a new feature were that they were slow and that they had a much shorter battery life.

Out of all my meters I use my Fluke 45 the most I'd say. It's in a good spot on my bench. I don't keep my other Fluke meters out on my bench as they would be taking up too much space, they come out as needed. Out of my handheld Fluke meters, the 87IV (which is really a 187) is my favorite.

I'd like to use my HP 405AR more, but it needs a good 15 minutes to warm up before it's accurate, it's LOUD and it's very power hungry.

I do not own these multimeters. Photos were found on the web. They are quite special, because they have a 19999 (4 1/2) display. They are probably both from 1994.

Compared to U1461A, F289 has much faster auto ranging.
I thought U1461A can be a good second DMM while also being an insulation tester, but the reality is it is really only good (productive) as an insulation tester.
On the other hand, F289 takes forever to boot up, and leaving it on drains the battery in no time.

I can't stand the S-L-O-W autoranging on the ohms function on the RMS225. I've owned a couple and tried another so I'm confident it wasn't just a one-of.

The complaint is more applicable to voltage and current functions.  I never noticed the slowness of the RMS225 ohms function but my DMM916 which can be considered a high end albeit old handheld is about the same.  This is suggestive as to why these meters include a separate fast continuity function as part of the diode test function.

Are more modern DMMs faster?

Hi

Glad you got it blastcap  :-+

Me again with another meter, just cannot resist them, my Fluke 187 arrived, not a very happy chappie :(
I bought it knowing the input jacks have sheared off  :(
The fuses are missing  >:(
The top half of the case will not stay on because the plastic for the screws have sheared off  :(
The rubber casing is coming off bcause the glue has failed  :(

Picked it up for £61 so a fixer upper. Before I spend any more money on it, I wanted to make sure it was working, I tried poking some voltage on wires into the holes where the jacks solder on but no joy. I then shorted out the 2 holes per jack and tried the same trick again. Winner winner chicken dinner  :D

So on with the restoration.

In the mean time here is a pic of the poor fella and the other meter I got but did not post a picture of laast time, a UT210E

Most of the meters I have owned have long been recycled.  These are all that is left.  Member 5ky provided both the Fluke 107 and AMPROBE AM530.  All are 100% functional except the TPI.   :--  The only ones that were not subjected to my transient testing are the Extech, Mastech and the UT210E.   All of the rest have been damaged and repaired (maybe more than once  :-DD) except for the Fluke 115, Fluke 110, and a little melted plastic on the HIOKI.  The meter that has been exposed to the highest levels was the Fluke 107.  The UT181A and the UT61E were both modified to survive some fairly high levels.  You can see the mods to the 61E below.  The ones I actually use are the Brymen, Mastech (expendable) and the UT210E clamp.     

One day I hope to see one of Dave's meters added to the mix.  With all of his reviews on input protection, you know his meter has to be right up there with the best.

Oh, it is definitely not a 6.5d accuracy meter. No matter how many digits are shown, it is still a 0.025% accuracy meter at best. But precision != accuracy. I'd be curious to see how linear the ADC response is especially at the 7th digit.
Still, the extra precision could come in handy for comparing two similar values within a short time. Here, absolute accuracy and drift don't come into play, just repeatability on a short time scale. An example application is measuring rail voltage at different points on a PCB to try to narrow down the location of a short circuit.

The 6th digit on the 7150plus is very drifty/noisy so it's of limited use, but it's fine if you treat it as a 5.5 digit meter.

Hey, I've got one of those too, maybe a couple of years younger and minus the holster, an irrisistable special offer deal.  Nice reasonably accurate meter, High-Z input on the lowest ranges too. The only problem is that the autoranging is slow, so it tends to go into bleep meltdown on fast changing voltages. Curiously, although mine is exactly the same WG022 model number its maximum current is 10A - maybe they found that they were pushing their luck on the PCB traces. Nice to see that yours is still fused though.

What is Zin for those old VTVMs I always wondered (I know it is high, but how high).

It just depends on the input voltage divider.  Tubes in general do not have a higher input impedance than FETs.  The claim to fame for a VTVM is that it does not have the low input impedance of say a 20,000 ohm/volt analog meter.
Title: Re: Show your Multimeter!

Meratester

My most beloved meter atm. straight from the 70..80's Poland. Have only BNC connection and one banana for grounding. I have two units, another one is in better physical shape, but this one is "spot on" through voltage scales.

As this have 100 Megs input in all DC ranges it is actually a picoammeter also (while nA is as low I have gone so far).  :) What I have found really nice for my odd hobby metering is the center zero selection, which splits the sensitivity range to half (negative and positive).
I wish I had the original "Radio Frequenzy Probe" since the HF button allows measurements up to 1000MHz with it (1.5 - 15V + 250DC max).

Anyway big claims on the "The only meter a laboratory need." isn't too far, really versatile meter and I suppose it is one of the best of the FET analogs there is (outside the big boxy benchmeters / metrology stuff). Also exported under Marconi and Conway brands. Uses hybrid amplifier.

ESD clouds around a room are real!!  ::) ;D

Here's some pics of my trusty Fluke 75 while it was open for a battery change. A long time ago it was connected across a 12V SLA battery with the probes in the 10A current sockets.

I recently took a photo of my actual Fluke multimeters family (https://c1.staticflickr.com/1/690/33201816031_8739b58704_o.jpg).

(https://c1.staticflickr.com/1/690/33201816031_2dd9ecb403.jpg)

Fluke 16
Fluke 111
Fluke 75 series II
Fluke 76
Fluke 83
Fluke 87
Fluke 87 III
Fluke 26 III
Fluke 179

The Fluke 83, still a recovery project, since it needs the LCD screen replaced because it's broken, and some contacts to one of the elastomer can't be done.
But so far, I couldn't find a replacement at a decent price.

If not, why two different references?

I think there's none. (the manual for both 26III and 79III (http://assets.fluke.com/manuals/7926____iseng0200.pdf))
I don't know. I never found an answer to that myself.

For the original and series-II meters, the 2x models were safety yellow, and the 7x models were gray.  Starting with the series III "tapered" design, they were all the same yellow/gray color scheme.  (The famous Fluke "trade dress".)  I think the only difference was that the 2x models were sold with modular silicone leads instead of the basic TL75 leads.  Maybe a carrying case or other accessories was involved, not sure since I wasn't really paying attention back when these models were new.

Here are some pictures of my very first digital multimeter from the early 1980s.
This is "Made in Germany" by ICD
The name is: "Supertester 680D"

It came with the 2 mm Hirschmann posts. The test cables I replaced at a later time with new flexible cables and MC 2mm connectors.
This was an amazingly small and powerful meter at the time.
And it came in this nice case with lid.

Today this old digital "Supertester" got a new battery and I hooked it up to my 10V reference.
Interestingly only one least significant digit in drift after 30+ years.

* Fluke 8010A. Bought DOA. Fixed (clean, replace display, capacitors, calibrate)
* Fluke 8024B. Bought DOA. Fixed (clean, replace capacitors, replace display, calibrate)
* Philips PM2524. Bought DOA. Fixed (clean, replace capacitors, calibrate)

(there's a theme here)

None cost more than £20 :)

There's a missing DT830 that I'm too embarrassed to show as well. I recently sold my newer meters (!) because I like these so much. I had a Fluke 77 and a Uni-T UT61E as well. Also had a couple of Uni-T 33A's, a couple of Micronta ones as well over the years.

Please remember:

a PM2517-X is the LCD-Type (energy saver...)
a PM2517-E is the LED Type (more cute and more hungry, but it have a plug for AC Adaptor also  ^-^ )

the Philips catalog was asking für 600,- DM. they was expensive.
There is a optional temperature probe, mostly you find PM2517 without that.

Thermal RMS? Do you know anything about that, how it works?
Title: Re: Show your Multimeter!
Post by: pelule on March 31, 2017, 08:47:19 pm
The AC signal heats up a resistor for a certain tim. Then a DC voltage is connected instead to the same resistor, which creates the same amount of heat. The DC voltage is displayed as RMS value.
Basic physics. The riesistor sensor component is the critical element for the potential error.
Same method is used in the HP3400A.
Advantage: able to measure AC signal with high frequency and high crest factor.
Disadvantage: expensive and slow.
For a detailed description google for the Fluke 8506A manual. There is a detailed description of the operation.
Also here in eevblog there find a some thread for this method.

Sounds the same principle as "thermistor' type RF power meters e.g. HP 432 and 8478. From an RF viewpoint allows nice/easy calibration at DC.

OK. Since we have a scope on this topic already, I'll show you something more interesting.
This scope I use at home. It's called C1-117. I saved it from a total destruction, because it has a lot of gold and other precious metals inside, so people just destroy them to take it especially if it doesn't work.
Although, the bandwidth is not very high (15MHz) notice the vertical scale of 0.1mV/div! Also it has cursors, which is uncommon among soviet scopes.
And it is quite compact in comparison with other analog scopes.

I think there is one of the early smd IC defekt, and I don`t know where I can get them.
They do simply functions, relatives of TTL, or a 5 transistor array. When switching ON it make one way from left to right, then stop.
seems to be the trigger or like that.

Hey Martin,

Sorry for the delay, could you send me a photo of the IC and part number, I will ask around @ local forums and guys who repair CCCP scopes, but if this scope is full of gold it might be hard to get it, most of scopes that had nothing but gold inside were ripped apart by gold diggers, also I will try to find the datasheet, then maybe you can make something up from current parts.

No, I'm not going to pile 'em up for a photo shoot.
Rather, I will feature some of them over the next weeks, which have some very interesting features..

But first, the (incomplete) list

Prema 6001
Schlumberger: 7151, 7045
Tektronix: DM501A, DM502, DMM150
Fluke: 8060, 87, 12, 79-III, 27/FM
Siemens: Multizet A1000, Multizet A1001, B1010, Multizet T, VMG1
Metrawatt/GMC: Unigor 6e, Unigor A43, Unigor A41, Metramax12, Metravo 4E/4H/4S/4D, Metravo Elektronik, Unigor3p, Metravo3, Metratest3
Hartmann&Braun Elavi15N, Elavi5, Elavi5N, Multavi6
Simpson 467(PSM45), Beckmann DM25xL, ICE Microtest80, Soar3100, AN-USM213, AN-PSM6, HP E2377A
Neuberger PKD4 (2x)
ITT Metrix MX1200S (Clamp Multimeter)
Amprobe 37xR-A-D

Patients and those waiting to be given away are excluded

First one was a far-eastern analogue similar to the Ultron UM-204, but branded differently, if I recall it right.  Then a Metravo 2H. Then things escalated quickly.
What can I say? they tend to accumulate, and yet, many of them have quite unique features.

Missing ones: there is a extremely rare Siemens, which looks like the A1000, but is a real A/D multimeter.
Also, I'm willing to try a 867 and I will probably replace the 87 by a 289. Keithley 2001 might be next benchtop dmm. Maybe a Siemens B1023, a Metravo 2035, the RMS version of the MetraMax12 (14), ...
Of course, the bigger Prema DMMs (5017/8017) are something that one should not chase away if it started to follow me around aaand I worked with the Analogic DP-100 a.k.a. UDL-45 and I liked it!
So, way to go.

By the way, does anyone have definitive information about the first REAL multimeter (doing U, R, and I; and at least AC/DC for voltage)? Here in Europe, the Gossen Mavometer is often quoted, but it needed attachments for every single range. The H&B Multavi HO and the Mueller&Weigert 'Metravo' (yes, it wasn't always/only used by Metrawatt; or, there is a murky connection between those two).

So, for starters, if you were to be flown to Mars (or whereever if it makes the decision irrevocable), and you could take only ONE analogue multimeter with you, which one should one choose? The UNIGOR 6e (or 6eP) of course! Combining the advantage of an analogue meter movement with the high input impedance provided by a FET chopper amplifier and sporting the widest choice of measurement ranges known to me in a multimeter, this instrument was the undisputed high-end product of Metrawatt as long as it was built. In a Bürklin catalogue from 1988 it is still listed with a price around 1300DM. 
Its measurement capabilities include capacitance, at a time when only very few DMM did this. It is made with superb workmanship and built using discrete components only. Especially formidable are the Voltage and current ranges extending down to 1mV and 1µA FSD respectively! All U, I and R ranges are class 1 (excluding frequency error at AC). Protection features are comprehensive including an automatic cutout.

Post by: Neomys Sapiens on April 25, 2017, 09:43:32 pm
Then there is the MetraMax12, a Metrawatt (now GMC) DMM with interesting features. It allows to reduce the input impedance deliberately to 400kOhm/V, avoiding thereby a lot of false readings. Its design history dates back to the Metravo2D, which was the first of Metrawatt's 'pocketbook-sized' DMMs. But since then, autoranging, Frequency, capacitance, Min/Max and a bargraph were added over time. There is a RMS version, which is the MetraMax14. Here shown with some original accessories (the large shroud behind the 4mm connector locks onto the disk-shaped protector on the probes). Nice to have, and I take it along often (at least until I get my hands on the 14). Here it is:

And at the other end of the scale from the Unigor6e (as far as analogue multimeters are concerned), there is the ICE Microtest80. Made in Italy by ICE, whose 680E and 680R are bigger versions built to the same principle (range selection by jacks). It is about 100x90x30mm in its box and uses a single LR9 cell. And yet: AC, DC Voltage, Current and Resistance, so it is a complete multimeter! Jacks are slightly bigger than 2mm, but the 2mm plugs with spring work. And it is a convenient solution for carrying a second meter even in the compact toolkit. Voila:

I like your taste of FET-analogs. Do you have any of the accessories? Mine (Goerz Unigor6e) do have had some form of damage in the past in the needle as the red coating have partly flaked out, but still it seems to be spot on what I have been able to verify the readings with my limited equipment. Do not start to collect these high (10M+) impedance analogs.  :-+

Err...too late! And why shouldn't I collect them? It's not that they distract me unduly from the other ones. As for performance monitoring, I had the 6e recently calibrated without problems (company paid for it).
In between, I have a little DC calibrator and I do spot checks against the big digitals.
As for accessories, only the test leads and a pair of grey Hirschmann leads with fixed probes (they resembled the original ones by the grey wire). I have multiple Metrawatt current clamps and shunts, which could be counted as such. What I would cherish most, is the original RF probe, but I am still searching for it.
But as you liked my taste in Hi-Z analogue meters watch for the next post - it is a real jewel!

Now to switch to the renowned company of SIEMENS, which once had a own line of multimeters and which also underheld various alliances with products appearing under dual brands (ITT Mueller&Weigert, Norma, Gossen..)
But here they are:
Even if I praised the Unigor 6e beyond comparison, here is MY favorite analogue active (amplifier) multimeter: The Multizet A1000!
It is a semi-autoranging instrument, which uses the 0...3 and 0...10 ranges (or equivalent, scaled up or down) on the scale for optimal reading and precision. The actually selected sub-range is indicated on the small LCD, as well as DC polarity (auto!) and battery and fuse status.It was built in two versions, and the one shown here is the extremely rare second one: when you want to stay in the currently selected sub-range, you advance the side mounted power switch to the third position and the range is fixed! This feature was missing in the first version. Interestingly, it uses Fe/Cu-Ni elements for temperature (type J), not the typ K as most multimeters. But I use it more often with the original Siemens active temperature probe, which was offered as accessory. Power is by 6AA cells, and that is where the problem is: on this series of multimeters, you should really really heed the usual advice about removing the batteries when not in use! If you don't, they will corrode to the point of taking the batteries with them. That was what killed my first one (version 1). It has a sibling for DC-only measurement with zero at midscale, the Multizet A1001 (I have and use it too). And there was a real analogue/digital multimeter in the same form factor, of which I do not even know the designation and which I am searching for.
(http://MultizetA1000_1.jpg)
And here is a Siemens DMM, which is also quite rare and special - the B-1010
It is only missing one thing (RMS), but even without it it's a good choice for power-related work.
It has an integrated phase-sequence tester, which is connected by a triple-lead assembly fitting into the leftmost jack. Interestingly, it works quite well in 400Hz systems. Also, a 30A AC range comes handy.
It has the same form factor as the A1000 and can do temperature using type K! Does one understand this model policy? Also powered  by 6AA cells. Here with original case and probes in pristine condition:

Now, having poured myself an IPA and assured that I don't miss anything elsewhere, I'm going to show you an even rarer beast, which I doubt that many of them survive and maybe none at all outside of western Germany: The Neuberger PKD4 analogue modular multimeter kit!
The company Josef Neuberger was situated in Munich and did build multimeters and other electrical test gear since the 1930s. It is best known for its tube testers and the Unavo/Telavo multimeter series.
The PKD4 Set was probably originally conceived as a training device and later adapted for professional technical use. It was made in the 70s of the last century.
It consists of a analogue, moving-coil instrument with the usual 10/30 + Ohms scaling which has a sensitivity of 60mV/50µA. It is connected by two 4mm jacks at the right side, into which the 4mm plugs of the associated range and function boxes fit. Measurement connections are to the front side and use 4mm jacks/plugs too. And there was a lot of those boxes:
Besides basic shunt and divider boxes as well as combined I/U boxes there are those with rectification for AC and resistance boxes (containing the battery too) in various range combinations. But that is not all - there was a DC chopper amplifier based voltmeter/microamperemeter with 2MOhm/V (PA6) and an amplifier AC voltmeter covering frequencies well beyond 100kHz with 1MOhm input (PA7) as well as a static (PA8) and a dynamic (PA10) transistor tester!  It came with an optional carrying case (shown below), which could accomodate 2 basic indicators and up to 8 range/function boxes. The accompanying brochure lists not only the characteristics and usage of the modules, but gives the complete circuit diagram for each one!

The makeup of it lends itself extremely well to self-build extensions and as I have lots of ideas I will have some compatible boxes made. I am not willing to sacrifice any of mine, even the redundant ones but I also want them to look exactly the same as the original ones. I plan to make a digital base instrument too, maybe with some memory functions or even a data interface.
One little setback occurs when trying to aquire the batteries needed to operate all modules: the IEC15F20 22.5V block battery needed by the PA7 and PA8 might be well made of Unobtainium! The PA5 and PA11 resistance modules use the 10F15 15V cell, which is only marginally easier to get. The PA10 uses two half-AA (not AAA) cells. I have resorted to fit 2mm jacks in the top side to connect an external supply when possible. Maybe I could build a nice, electrically stable linear power unit for all the options in the same size as the base instrument. Presently I have 2 base instruments with 11 modules and 1 case.
(http://PKD-4_1b.jpg)(http://PKD-4_2b.jpg)
Here the base instrument with one module, second picture shows them partially connected:

My latest multimeter acquisition, a Fluke 37. I got this one really because of its industrial design -- the storage compartment, the carrying handle, the clip-on stand and so on. I think that electrically, it's a Fluke 27. Just in a different (much bigger) case. I haven't started to restore it yet, but will clean it and probably also clean the zebra strips in the LCD.

It's fascinating that FET VOMs seem to have had a much bigger run in Germany and continental Europe in general than in the US.  It seems like here they just existed in a short decade between VTVMs and 3.5 digit DMMs.

I have recently obtained a Micronta (Radio Shack) 22-220A which seems to need repair.  I'm hoping that if it's the matched JFET pair that's damaged I won't have too hard of a time replacing it.  It's an µPA68H according to the schematic I found elsewhere on the web (reposted here because it was too much effort to find).

It's particularly amusing that they borrowed the industrial design of the Simpson multimeters, albeit cheaply.  It's made in China (no mention of Taiwan, so I assume mainland China, so probably late 1970s or later?)

I think there are various aspects to it. At least here in Germany, you have a higher level of technical training especially at the craftsman/technician level. I mean, an engineering degree is (and was 50yrs ago) closer together on both sides of the atlantic ocean than the idea of what makes an 'electrician'. So, the problem of difficult to read analogue meters was less important, as the potential users were assumed to be properly trained for it.
Then, there might have also existed a deeper 'technical conservatism' both on the side of the instrument makers and users.
Also, US instrumentation companies such as HP, Tek, Keithley etc. were far more present in european markets than the other way round. So their DMMs were available and actively marketed. My first DMM was a Fluke 8060A and it was among the first batch sold over here. I remember selecting it over the Beckman 3030RMS, and there was no RMS handheld DMM from german manufacturers at that time (about 1983).
My boss at the engineering office, where I worked while still in school, who was certainly up to date, as we were doing quite advanced automation stuff, was not convinced - he advised me to go for one of the big Unigors, as he distrusted sampling and numeric displays not to show him really what happens.
So companies over here might have cultivated the analogue niche market for longer.
My first electronic analogue MM was a Philips PM2505, which came after the Fluke, when my older Metravo2H (passive) did not survive a unexpected contact with a 750VDC streetcar supply line in a traffic control installation.
GMC still sells an active analogue multimeter in the guise of the METRAport3A (practically the same than a Metravo 3E). Of course, both in this one and in the Siemens A1000 which I presented ICs have taken the place of the simple FET pair.
But the phenomenon is not limited to the active (FET/amplifier) variety. For example, the multimeter pool at Rockwell-Colling Germany contains lots of the old black Siemens Multizets with their class1 spec. They are calibrated regularely and treated well and I see no reason not to use them in complex lab work, where you really measure one or two signals but have ko keep an eye on some others.

I decided to post in this old thread to share my collection of multimeters.
Like many forum members I buy a new multimeters (or a new soldering station) even if I do not need it, but my wife has the same problem with shoes :), and the last multimeters I bought  were cheaper than a pair of shoes :-+

In fact a new one arrived after I shoot the collection, and is not in the photos: a nice ANENG AN8002.

Photo 1:
- WAVETEK (Meterman, now Amprobe) 5 XL  : a basic 3.5 digits, very robust, with the best display in the collection
- Meterman (now Amprobe) 33XL : a very robust, reliable, SLOW 3.5 digits HEAVY meter.
Please note that it has leading zero suppression, that's a little unusual but nice.
- UniT UT61A : I don't know why I'm always grabbing  this one as first choice :D
- UniT UT61E : I needed true RMS :-+ to replace an old Beckman that was sold in the last clearance of the lab.

Photo 2:
- STANDARD (no name ?) clamp meter
- Meterman (Amprobe) PM33 pocket: I don't use it very much because the single button operation is annoying, and I don't like the fixed probes.
- PEAK TECK 1020 pocket: it is a nice instrument with flashlight and Non Contact Voltage detector.
New production has detachable/replaceable probes. The display is good, but it is placed too far from front panel, so reading at an angle is difficult.
It has no tilting stand, but I've found on the Web that some maker made a nice attachment.
- ANENG AN8008: recent arrival. It is very nice, I like it very much.
Same for the not shown AN8002.
Please forgive the photo's low quality.

No, they were similar but different products from different manufacturers. I used both of them (but I preferred a bigger AVO 8 ) , and after more than 40 years the ICE is still in production (you can buy it on RS).
The ICE was 20 kohm/V, the Cassinelli was 40 kohm/V.
In this webpage http://www.webalice.it/rocco.piccone/progetti/cassinelli/cassinelli.html (http://www.webalice.it/rocco.piccone/progetti/cassinelli/cassinelli.html) youcan find schematic and manual for the Cassinelli.

@Ciccio: As you seem to be quite knowledgeable on this topic, how are they (ICE/Cassinelli) related to Chinaglia and Pantec? (Like, is the Cortina related by design to the later Pantec's?)
And how comes that the ICE and the Cassinelli share so many features, which are not commonly used in other multimeters (switchless, jack size, range doubler pushbutton, layout).

Also, I have a very specific problem with a T&M instrument from Italy: I own a 'fast transient monitor' from the deceased company 'Ingeneria Guido Gay', the FTM30.
If it is of comparable quality like his memory voltmeters (which I use), it should be good. That feller was a analogue wizard and designer of nice instruments! But I have been unable to find ANY information about it! Even to check it out, would need some manual. Any idea? I would be sincerely delighted!

I'm sorry, but I do not know much: Chinaglia and Pantec (Carlo Gavazzi) were located not in Milan (or near Milan) like ICE and Cassanelli, but in the east of Italy (Belluno).
The layout and special functions were, to what I understand, selected for differentiating from other European manufacturers.
I never heard about "Ingegneria Guido Gay". I did a quick search and found this page  http://www.underwateracademy.org/it/press-area/archivio-news/16-biografie-tridenti/1980-1989/140-1985-guido-gay.html (http://www.underwateracademy.org/it/press-area/archivio-news/16-biografie-tridenti/1980-1989/140-1985-guido-gay.html) where is reparted about a submarine robot and the discovery if a WW2 wrech, but I don't know if he is the same Guido Gay.

At present I have two meters. I'm waiting on a 121GW that I expect will become my most used meter. The 34970A unit has a 6-1/2 DMM that can scan multiple inputs. I have a few switching cards too. It's very handy for testing designs because I can connect several nodes and then scan them as I vary inputs or loads and log over time with temperature. I bought it for that purpose. I most often use the Fluke for general tasks but I'm ready to move up to the 121GW.

Well, wanted a new 15V battery for the Avo8, and did not want to buy an expensive one online. so, looked around, and took 5 CR2025 cells, some PTFE sheet and some scrap brass from a well cooked socket outlet, and some thin heat shrink sleeves.Now have a nice 15v battery replacement that should last at least 10 years in use, plus the zero adjustment is now at the point that should give a maximum battery life.

Now to await the slow boat from China with the AA converters to replace the D cell for the other ranges.

Also, I have a very specific problem with a T&M instrument from Italy: I own a 'fast transient monitor' from the deceased company 'Ingeneria Guido Gay', the FTM30.
If it is of comparable quality like his memory voltmeters (which I use), it should be good. That feller was a analogue wizard and designer of nice instruments! But I have been unable to find ANY information about it! Even to check it out, would need some manual. Any idea? I would be sincerely delighted!

I never heard about "Ingegneria Guido Gay". I did a quick search and found this page  http://www.underwateracademy.org/it/press-area/archivio-news/16-biografie-tridenti/1980-1989/140-1985-guido-gay.html (http://www.underwateracademy.org/it/press-area/archivio-news/16-biografie-tridenti/1980-1989/140-1985-guido-gay.html) where is reparted about a submarine robot and the discovery if a WW2 wrech, but I don't know if he is the same Guido Gay.
Best regards
It is the right guy that you've found. Also 'Gay Misuratori Elettronici' is the correct company name.
That he was active in underwater robotics was not known to me before.
Here are my two MTA memory voltmeters (peak voltmeters) from his company:
But for those I have documentation. The other two pictures show the FTM, whose case remains, unfortunately, unsolved.

But for those I have documentation. The other two pictures show the FTM, whose case remains, unfortunately, unsolved.

You've just reminded me that I have one of those MTA memory voltmeters stashed at the back of the cupboard. The battery is obviously shot (again - I replaced it when I got it, about 25 years ago but it hasn't been charged since :palm:). The only documentation I have on it so far is the spec... http://helmut-singer.de/pdf/gaymta.pdf (http://helmut-singer.de/pdf/gaymta.pdf).

Regarding your FTM, they appear to have made (at least) two mains voltage monitors, the LVA and an 'unknown' model - that's from the Telford Electronics manuals list... http://www.telford-electronics.co.uk/manual.php?alpha=g (http://www.telford-electronics.co.uk/manual.php?alpha=g). They might possibly be able to help you.


EDIT:
I've spotted a listing for an FTA (Fast Transient Monitor) on ebay, maybe the seller has some information? https://www.ebay.co.uk/itm/Fast-Transient-Monitor-FTM/222411921416?hash=item33c8c89808:g:L1cAAOSwWxNYpdVj (https://www.ebay.co.uk/itm/Fast-Transient-Monitor-FTM/222411921416?hash=item33c8c89808:g:L1cAAOSwWxNYpdVj). A nice looking piece of equipment, sounds ex-MOD.

EDIT: Well the MTA still works and reads fine after all these years. The battery is well gone (longer than I thought since I changed it, datecode 1989!). Very few electrolytics in there, but the Orange one looks pretty sad. While I had it apart, it seemed worth taking a couple of snaps (outer metal shell removed + inner isolated case lids)...
Title: Re: Show your Multimeter!
Post by: Neomys Sapiens on February 14, 2018, 08:31:00 pm
Yup, it's a really nice instrument.
Should you need the manual (with diagram) of the MTA, that could be arranged. But only if not too pressing, as I'm quite swamped with things to do.

As for the FTM, the offered one has pics showing the special (reverse Lemo?) input connectors. When I saw them first, I thought about replacing them, but their inner side is under a massive soldered copper sheet cover which clearly says 'magic - keep out or be damned'.

That's very kind of you, thanks! No, it's absolutely not pressing (it still works) but it would be nice to match it up with a scan of the manual.  I could upload it to KO4BB too, if you have no objection.

I hope you have some luck with the FTM. Those look like the same connectors as the MTA (luckily mine came with a lead). Yes I suspect that they are Lemo triax but I haven't managed to identify which one. Now all I need to do is find the MTA mains lead, I tested it earlier by jumpering the battery. It's a non-standard mains connector - I just hope I haven't forgotten what it was for in past years and 'salvaged' the cable.  :palm:

Thanks again,

Chris

Edit: Aha, looking on ebay, there seem to be a lot of Lemo triax connectors - and strangely, they're all in Germany!  :) There appear to be sizes 0s, 1s, and 2s though, so a little bit of research needed. Not ridiculously expensive though. https://www.ebay.co.uk/sch/i.html?_from=R40&_sacat=0&_nkw=lemo+triax&LH_PrefLoc=2&_sop=15 (https://www.ebay.co.uk/sch/i.html?_from=R40&_sacat=0&_nkw=lemo+triax&LH_PrefLoc=2&_sop=15) There are some copies from China too.

I got a new meter and I mean NEW. Heck I have not bought a new meter I think in past 15 years.

This little and cute meter is second best in the market (in its class), what I did found. The mechanical design is really satisfying and so nice compared to all the rubber bricks mainly floating in the market today. This one is "Made in Japan" unit and not the "$anMa made in hing kung".

Sanwa EM7000 a "modern" FET VOM, how I could resist and I didn't.

Micronta 18-Range Multitester was given to me by a widow whose late husband was a gas fitter. I think he many used it to test batteries and continuity. Sill boxed with the Radio Shack battery.

Also a Beckman Industrial 310 with the leather case which I used at work and they allowed me to keep it when I decided to leave for to join another company. It was a goodbye gift.

Hey SullyRD, do you have a source for the banana plugs? They seem to be of a rather odd size. I scored a Chinaglia Cortina a while ago on a flea market, but no probes came with it and I haven't been able to find them in the right size. They seem to be of the same size as the Novotest/ICE.

Sadly also the power supply to make the square wave generator in it work also didn't come with the unit, but that should be easy to fix.

Hi have a 7150 but the front panel says Weston. I used to work at Schlumberger in a division that used to be Fairchild and there was all kinds of old test equipment there because this was the test equipment division.

Haven't posted in a while but was still lurking.

While designing a small PSU for a RIAA amp I discovered that sometimes even seven meters are not enough. So I remedied that:

First something I wanted ever since it was discussed here, the Fluke 8060. I love it. If it had autoranging it would be perfect.

Then this Philips PM2517E just turned up. It was very dead and required quite a lot of surgery to be brought back, luckily the special IC's needed were available from the Netherlands.

I had the chance to get these two BEWA meters quite cheaply. They were made in Germany in the early 80ies, really some of the first
affordable digital meters available in Germany. They're just bog standard ICL7106 meters. Both meters are basically the same apart from accuracy specs.
There's BEWA's full size, full colour advert from the back of an Elektor magazine from 1984.

MY Multimeter Zoo has been expanded by a Metrawatt M2036 while I was on a short vacation. Left the bid and won. Now I hope for fast and well delivery. Not that I needed it, but my multimeter sense was itchy anyway and it was on the list. I am curious how well the zoom function for the bargraph works in practice. I consider the function offered by it to be more practical than those of the closely related M2035, which has a very particular limit function instead. And it has peak function, good basic acuracy and RMS measurement, so it is going to be a viable instrument. It is my first of the Metrawatt swiveltops.

In the early 80's, I was working beside school in a long defunct local electronics shop, as was a friend of mine. I already had my Fluke 8060A, which my buddy had followed with a Beckman 3030RMS. So when the shopowner came gloating about the 'super quality high performance economy multimeters' from Bewa, we both were not exactly impressed. But as I got a provision, I used the RMS feature on the big one to sell two of them in the tinkerer comunity at our school. It made RMS and 4.5digits accessible for some guys which were not willing to spend as much. Never owned one myself, though.

MY Multimeter Zoo has been expanded by a Metrawatt M2036 while I was on a short vacation. Left the bid and won. Now I hope for fast and well delivery. Not that I needed it, but my multimeter sense was itchy anyway and it was on the list. I am curious how well the zoom function for the bargraph works in practice. I consider the function offered by it to be more practical than those of the closely related M2035, which has a very particular limit function instead. And it has peak function, good basic acuracy and RMS measurement, so it is going to be a viable instrument. It is my first of the Metrawatt swiveltops.
I was still at the university, when this DMM came on the market and wanted it so badly but it was soooo expensive.
Hmm, I should look for one.
How much dis you pay for this one?

110.-
But a year ago, a colleague of mine, who was acting on my suggestion, got his for around 75.-
And a correction: the one with the different function in the same package is the M2037, not 2035!

But there was a bigger one , which combined both functionalities and added dB with selectable reference.
This was the M2042. I'm still looking for one.
You are sure that the M2036 was the DMM of your studential pipedreams and not the 2042?

Beautiful ICEs. I inherited from my dad the first multimeter I have ever used: ICE 680R Supertester. It is a bit off in all ranges but it is certainly on the line for a repair.

One tip, though: if possible, could you upload the photos to the EEVBlog server instead for posterity? Over the years the image hosting sites tend to either change their terms of service or the links become broken and thr images are gone forever (check the first post on this thread, for example).

I've acquired a few DMM's over the last year, but this meter is just more enjoyable to use, since I don't need "absolute" precision for most measurements anyway. This FET-VOM is like the slide rule of multimeters, to my way of thinking. That extra step of thinking about the ranges again before reading.

That was a good price, congratulations.

It is well possible that it is the M2036 that I had in mind.
Not far away from the university, we had a BBC / GOERZ / Metrawatt distributor.

Even these days, I am using my Metrawatt analog meters for some applications.
And even compared at todays standard, they are kind of special.

Here are some pictures of my little collection.

Not bad. Die 'Viererbande' habe ich komplett! (4E/4H/4S/4D). ;D
The 2H was my first #real' multimeter, bought together with a proper toolbag from the result of my first summer break job - doing electrical installation work with a local contractor aged 13!
The MetraMax12 and the Unigor 6e have already been subject of two posts of mine in this topic.
Mayby I should present the 'medium' Unigors (A41+A43) too or I could show the lower range precedessors of the 1H/2H, namely the Metravo Elektronik (which is not a 'electronic'=active multimeter, as the name suggests) and the Metravo3 and Metratest3. Also on stock is a Unigor 3p which is
interesting because those early series unigors exist in identical form from Hartmann & Braun, which then ceased to cooperate with the Goerz/BBC conglomerate. That was before the H&B multimeters grew to shoe carton size. The 3p sometimes comes handy with its 5kV range.

Aaaand....not a new multimeter, but I have finally managed to aquire the original Goerz RF probe for use with the Unigor 6e. Rated to 800MHz. With case and accessories, in nearly immaculate condition.

Like others on the board, my meters reproduce while I'm not looking!

On my bench are a 29 and 79 series ii, an 87 i, 2x87 iii, 3x8060a, and a 12b.  I'm in the middle of re-capping two of the 8060a meters and I've been using the rightmost 87iii for electronics work.

My most recent score was a cheap Matco MD257 (rebadged Brymen BM257)... its low-z function is great for exposing ghost voltages around the house and works as well as the Fluke 12b.  The Amprobe AM47 (another rebadged Brymen) is great for a pocket meter but the low-z on it sucks - it's not low enough!!

Eventually I'll pare down to one Fluke 87iii, the Matco MD257, and the IBM 8060a.  I might keep one regular 8060a too... I used it back in college and it's always been reliable.

I've been thrue a lot of handheld multimeters, this is the three most advanced i've got.
Fluke 289 - Keysight U1282A - Metrix MTX3291

The verdict is that the Chauvin Arnoux/Metrix MTX3291 is my favourite for the bench,
second place goes to Fluke 289 (and 17B+ for less demanding work) and the poor Keysight gets place number three  :)

I recently visited Tokyo's Akihabara district.

There, I found this little analog gem. Brand new, and Made in Japan. As seen from the sales receipt, 4320 Yen.

I had a similar one almost 40 years ago, which I unfortunately lost.

Ex. USSR 6 1/2 multimeter V7-54/2
Base accuracy 0.0015% /year
REF based on zenner 5ppm/1000h class (2S108R).
ADC PWM type, like Solartron ADC.

Design year of this multimeter may be 1989. Production year of this unit- 1992.

Fluke 8502A. The last digit of my Fluke 335A is out and that is why we get a six on the end. Otherwise, impressively spot on, and right out of the box from seller "potomacestore" on eBay, just $126 USD delivered! (Not a paid endorsement, but giving them due credit.)

Yet another interesting stuff of USSR Metrology: V1-18/1
This is 7 1/2 DC differential voltmeter and DC calibrator with base accuracy 0.001%

Heart of this Voltmeter-calibrator is REF based on two 5ppm/1kHr zenners (2S108R) and PWM multiphase (12 phase) DAC.

Teardown photos of this voltmeter-calibrator here: https://yadi.sk/d/IBVTJWrx3PbyWC

On the first photo this unit on the top "on servicing". Bottom unit is 6 1/2 multimeter V7-39
On second photo this unit acts as calibrator.

May be a'm wrong but I think, that V1-18 has designed in early 198X.
V7-39 as far as I know has designed in 1981.


On the photo close-up of V7-39 which measures ultra precision 10kOhm resistor. (sorry, now i can't show teardown photos of V7-39)

V7-39 is 6 1/2 0.01% accuracy
REF on this multimeter based on ovenized 5ppm/kHr zenner 2S190U (9.1V), ADC is multi-slope integrating type.
Last calibration for this unit is 1991 year and I might be lucky, but the check after the repair this unit showed that the instrument is in the class with a large margin and don't need any calibration.

A follow-up to the Metrawatt 2036, here at work checking a little electronic load unit:

[attach=1]

I definitely like it so far, the frequency of use was only limited by the aquisition of a Tek THM560 soon thereafter. Now, the Tek has migrated to my day lab (place of work) and the 2036 will find itself busy more often.
