Show your Multimeter!

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.

Which is you go to meter?

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.

Beautiful gear, Martin M.

Not sure if I posted this here yet...

Fluke 883a Differential Voltmeter

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

I am cheating here because I posted my multimeter here before BUT I have some new additions 

Previously shown :
Tenma 72-7755 (re-badged UT70B)
Keysight u1232a
DT830 (the cheapo death trap  )
Standard ST31 or Maplins Gold N21FR (interresting DMM with light, sound, temp and humidity)
B&Q clamp meter
Thurlby 1905a bench meter (5.5 digit)

New:
UT61E
Solatron 7060 (6.5 digit) 

Thinking about getting
UT610E clamp meter
Fluke 87 (been trying to score a cheap one on ebay - missed out on 2 so far  )

[willb]

A few new additions to the family (the 289, 233 and 374).

[VK5RC]

@willb that is a nice collection, I think a 8060a would look really nice in there ! It is a classic! (HiHi)

[willb]

In due time! I'm patient when it comes to picking up meters. I'll certainly pick one up when I come across one in good condition at a good price!

[Blastcap]

Well, we all got to start somewhere.
This multimeter collecting is a deep rabbit hole.

Welcome to the forum!

From a clue in your picture, I think you might be living in or near Sachsen, right?

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 

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

[retiredcaps]

So on with the restoration.

I would love to see your progress of this 187 restoration in a separate thread.  The 187 is one of my favourite meters!

Thanks.
You are right, didn't notice the bottlecap before.
Been here lately? The "Freiberger Edel Keller" hasn't been on the marked for more than 6-8 months i think.

[jitter]

No, alas, the furthest east I have ever been was to the Harz, and that was in a time when the iron curtain was still up. I was a child then, but I still remember seeing the signs with "Halt! Hier Grenze."
Other parts of Germany I've visited are Sauerland, Eifel and (of course) Schwarzwald.

I could just make out "Edel Keller" on the bottle cap, Google did the rest.

Here is my Gossen Triohm ohmmeter . It s not the newest but it is still accurate you can see on the pic . Spot on at 1000 ohms 

[joeqsmith]

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  ) 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.

Did you know that the Thurlby 1905a has a 6.5 digit mode? Press [**] then [5¹/₂] to enable it. I recommend using the filter to help stabilize the last digit.

[MosherIV]

Did you know that the Thurlby 1905a has a 6.5 digit mode?

Yes, I do.

I am not sure how accurate the 6th digit is. It was probably never engineered to be a 6 digit meter.
I have powered mine up and will compare with the 7150Plus.

My problem is that I do not have a reference with low enough noise to get definitive results.

[TiN]

There are few more abandoned cold Keithley 2001's in the another room. This one already look like disaster big enough.



I know you guys will hate me..
bottom HP3458A (reader's) and my 4920M jump on the train with me tomorrow, to travel 170km for little Taiwan calibration plugfest meetup. 

[ManateeMafia]

You will have all that empty space without the 3458A on your way back. Make sure you fill the shipping container with more goodies to keep that 4920M secure.

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.

I must have missed something...

There was an earthquake in Taiwan?
It must be a heavy one: There is even an australian style Keithley...
