One hour of 'Pocket Mutimeter Shootout' heaven for the viewers  :clap:

How many hours spent to produce it?

Would welcome a quickie Part 11 specs shootout


FWIW, Sanwa PM300 looks like it will survive drops better from 'shirt height' which is bound to happen,   
bent/sat on in the jeans pocket, weather extremes, rain etc when closed,
and probably live through some cat and dog chomping too   :scared:

Not that long, maybe 3 hours to shoot, and 2 hours to edit.

Yes, the rubber case would be the best in that regard.

My UT120C shows 10.17nF so it is a feature not a bug.

Perhaps they realised it couldn't read low values accurately (or at all) and whacked in a 10nF in parallel and rely on the delta function to read lower?

I've noticed the 10.17nF thing too on my UT60x (can't remember the last letter). From memory the manual even told you to use the delta function for small capacitors.

I googled DER EE  http://www.hktdc.com/suppliers-products/Pocket-Multimeter/en/1X00III0/1960503/
They sell a DER EE  pocket multimeter model DE-19A which comes with a current probe and I am guessing that extra
compartment at the back is for that.

On PCB build quality, layout and no after thought looking components I like the Hioki the best.
But as a pocket multimeter I like the Sanwa PM300

Need one that measures current safely?




PS: Am I the only person in the world that's noticed that you can EASILY close the case on those cheapie slotted-case meters when the switch is in the wrong position?



(...and that it's almost impossible to open them again afterwards?  :scared: )

What's the thing circled in red on the DER? Why is there a gap in the case there?

Maybe the space at the back is for a different model with an expansion module or something.



It looks like there's enough lead inside that you could wiggle out a few mm to make the wrapping+storage a bit looser. It should definitely be a bit looser by default though.

Edit: Aha! Mystery solved! They make a version with a current probe that attaches there. The extra space at the back is to store the probe:

For what it's worth, the Aneng AN8203 does indeed have a tripod stand.  In fact, it's one of the best and most sable I have ever used.  Just don't throw out the little strap it comes with.

Interesting how many of these are both CE marked and rated CATII. To be CE marked (properly), it would have to meet IEC61010 and the section on multimeters explicitly states that anything rated for connection to mains must be CATIII as a minimum.

But a CE mark can be self certifying, it does not have to be independently EMC or safety tested. Hence the majority of multimeters sold that are not independently UL/ETL etc tested for safety.

would it be a good idea to compare the best 3 pocket meters to a small Brymen (BM253) to see how they perform against it.
I bought a fluke 101 recently and it's slow and vague compared to my other meters. (measuring resistances is painful.)
I'm thinking of getting a keysight U1242C when I have the funds.

Interesting to note that the AN8203 was bang on until you killed it.

DAVE, you should open the AN8203 and at least see if it was anything easily fixable.

Voltlog #162 - Pocket Multimeter 1KV Testing and CAT Ratings

In this video I am testing the pocket multimeters by applying transient voltages to their inputs (generated with a Brymen 887 Insulation meter) and we’re also going to talk a bit about CAT ratings and what they mean.

If the display went blank then it's probably the main chip.

Does nobody else hate the wallet cases? They put the probes right in the 'hinge' so they never close properly. Always flapping around and opening.  :scared:

Also: How long before the bits of velcro come unstuck from the probe straps? Don't tell me you never saw that happen.


(Maybe Sanwa have some magic velcro glue but I'll wait for the long term report  :-// )

Maybe Dave's AN8203 sample was defective. Here: https://youtu.be/pnv5qJoWIak?t=693 he's uses an even higher voltage but for less time and didn't kill it. The ohms short seemed to show the PTC cooling off I think.

I still prefer that loud continuity beeper over the Uni-T, and IMHO that little Sanwa would be a welcome addition to the store.

Maybe it's luck, or maybe a slight variation on what's inside. Those meters are like DT830s, there's dozens of variants with completely different internals.

I still prefer that loud continuity beeper over the Uni-T, and IMHO that little Sanwa would be a welcome addition to the store.

Mine definitely has a loud beeper. Out of the three pocket meter I own it's the one that feels most like a "real" meter, I just hate the case and it doesn't do amps (which I want - I don't ever go poking at mains AC with mine).

In my video on the ohms range, it can be seen in the video, the insulation tester I used could no keep up with the low impedance of the target and the voltage dropped close to 0 so that test does not help at all. However it's worth noting that on AC/DC voltage the meters had no problem with 1KV applied. I wonder what did Dave use when he applied that AC voltage on the ohms range, was it AC from a wall socket (high energy)? or something generated by one of his power supplies?

Doesn't he have a piece of Keithley gear for that? a vintage unit, with big decade knobs etc..?

It's a shame the Sanwa CD800b / CD800f are so big. It would be awesome if they could fit those specs into the PM300's footprint.

That's why I was wondering which source did he use in this test, because I remember he has one of those voltage sources that could go quite up, it wasn't visible in the video though.

Although Dave didn't seem to think so, I find my UNI-T 120C case has pretty easy probe storage.

I agree. At first glance it looks like you have to wind them carefully around the posts but you can just shove them in if you want. Same for the ANENG 101. I really like those style of cases more than the wallets.

It's clear Dave likes wallets and pretty much rejected all the ones with amps ranges. His main criteria seem to be CAT rating and loud buzzer.

(which is fine - horses for courses, but YMMV)

I take mine along to Arduino club a lot and it's good to be able to check the power consumption of people's little circuits. They're mostly USB powered so 400mA with a polyfuse is enough for that.

Besides: I noticed the famous Sanwa case never closed properly in the video because wires were sticking out every time. I know Dave's looking at a tiny screen and trying to do everything around a tripod, but... it caused a bit of LOL here.  ;D

Didn't he say the AC was 400 Hz ? (so, no wall socket mains)

It also happened to every other meter when you don't bother to store them properly before closing.

Insulation testers typically have bugger-all power capability, they don't have the ability to dump a large amount of power into the DUT (and hence any failing protection devices). MY EDC reference can deliver 20W at up the 1KHz up to 1000V

No, they are a different class of meter designed for different uses IMO.

I noticed that too, but it wasn't worth commenting about because it was obvious Dave didn't lay the leads down properly - which, during a 14 unit shoot-out, isn't hard to understand.

As Dave says:
It also happened to every other meter when you don't bother to store them properly before closing.

Yes, I know, but it was quite amusing to watch Dave telling us how great the case is and the case fighting back the whole time.

I noticed that my new PM300 did that as well, until I used it after about 20 times and the brand-new cable twisting is almost gone. The trick is to put the probes first into their proper place and then mold the cables behind the tab that holds them in place.

I've got two UT120C meters bought back in 2013, both with 09/2012 production date on the back. One of them I carry around in a document pouch so it basically goes everywhere with me, mostly to be used every other day at work if needed. The second one is a garage meter. They are quite durable, after 5 years the cases are now definitely less transparent from all the scratches and do not lock properly anymore,  but the meters inside still pretty much look almost like new. Of course they both share the same flaw on capacitance (10,15nF minimum reading). Both meters have survived some accidents and they still work fine, so I'd say they were definitely worth buying.
Btw, I think the UT120C cases were designed to wind the probe wires around the holders inside instead of just sticking them there. At least it works for me, I've been doing that for years and never had a problem with probes or wires sticking out from the case.

That Amprobe DM78C kinda looked like bargraph just had insanely high refresh rate

Bargraph updates the moment Dave touches the output while display updates ~1s later.

Kinda looks like sampling speed was in tens or hundreds and bargraph got unfiltered output of that, while display got averaged one

Where mention of the batteries used in these pocket multimeters?

I've seen AAA, CR2032, SR44, and 12V A23 batteries used. Some need a tiny Philips screwdriver to access the battery.

Since these DMM's are often used in the boonies, a dead battery can be either impossible to find or that screwdriver you left at home is needed.

That Amprobe DM78C kinda looked like bargraph just had insanely high refresh rate
Kinda looks like sampling speed was in tens or hundreds and bargraph got unfiltered output of that, while display got averaged one

Bargraphs are usually 20/sec updating or so.

Have you ever heard of this brand of pocket multimeter? https://au.rs-online.com/web/p/digital-multimeters/1336519/
The idea is you have one probe clipped on the back, and use that in one hand, with the other probe in your other hand. It seems like it would be an awkward use for bench work, and only seems useful for wall-mounted electronics. I quite like the display though.

It's usually called a "duspol", it's mostly for electricians. The idea is you don't need three hands to use one when you're standing up and walking around.

Lots of companies make them, even Fluke: http://www.fluke.com/fluke/m2en/electrical-testers/electrical-testers/t90-t110-t130-t150-voltage-and-continuity-testers.htm?pid=73757

I quite like the display though.

Given the way you use them I think it would be better if it was readable in the vertical orientation.



If you like orange displays you might be interested in Agilent multimeters.

Dave made me buy a 2nd Sanwa PM300, how?
He cut the price! Got to NY in 10 days, nice job Dave.
I’ve seen all the others, own a few, but still think the Sanwa is the nicest. Tucking the cords inside is the only real complaint I have. Super accurate tested on my DMMCHECK Plus.
I think I’m DONE buying pocket meters, he said ........

Does anyone know where I could buy a set of the small test probes that come with these pocket meters? 

I've had a Metex P10 for years and it's not a bad little meter (built in 1.5v battery tester!) but inevitably one of the wires broke at the top of one of the probes where it gets bent the most.  I've bodged a repair by cutting back the plastic and soldering the break and protecting it with some heatshrink, but I'd rather replace the probes/leads if I can.

If you want to repair a favorite meter then a lot of the meters in this thread cost about $10. Snip the leads off one!

You could try Frankys thread on this site here:
http://www.eevblog.com/forum/buysellwanted/franky_s-sales-thread/

Or his online store here:
https://www.ebay.com/str/99centhobbies

If you find small enough ones for your pocket meter, just cut the ends off.

A $10 meter for $1 test leads to fix a meter that's probably worth rather less than $10 doesn't add up for me.  I like the meter, but I'm not that sentimental about it! 

Edit:  Having said that it seems you can pick up a pocket meter for under $5 shipped from China which is ridiculous, but a possible solution so thanks!

Thanks I'll take a look, though I spent a good 20 minutes on eBay to no avail.  I suppose most people would just bin the whole thing and buy a new one.  If it comes it I'll wire in a full sized pair of probes, I just won't be able to store them in the holder.

I've received  one of these meters as a gift, it was the uni-t 120C in chrismas.

The 10nF residual capacitance is present, which not so good, but in terms off voltage reading, frequecy, even capacitors >= 100nF is quite in spec. Has nice digits and some diode protection, PTC, clamps and a polyfuse for current, which is usefull for low power apps ( microcontroller). I do like the plastic case, keeps from been poked by the leeds. I carry on my bag as an extra.

About the review, the Sanwa seems very nice and best value for the money, but has the rotary switch that pertrudes a bit towards the case and can be pressed if using in your trousers pocket.

PS.: The continuity for the uni-t 120C is bad :S

Here are some photos of first power on and inside, for checking battery, signs of corrosion, etc.
