I was thinking about testing some pocket meters.  Some are so small, I bet they would cut loose with a pretty good bang.   

Agree on the two low cost Flukes.  The 107 was about $108 and the 101 about $50.   They don't have a lot for features.  The 101 does not even have a back light.  But they both appear to be very electrically robust.

  • When in doubt, add more flux.

108$? what?

That's a good price.   I had checked Amazon just after 5ky sent the meter.  Checking now, $118.   :--

Since "high quality" and "compact" are quite subjective, I have to say that my go-to multimeters have been those lovely 830s - i have been  using them since the 1980s.

I am very happy with really compact UNI-T UT210E.


Topic: https://www.eevblog.com/forum/testgear/a-look-at-the-uni-t-ut210e/
Specs: http://www.uni-trend.com/en/product/2014_0717_650.html

It is way more precise than Extech EX330 and Fluke 17B (which I also have) on all ranges...

That reminds me I have a box of about 8 pockets meters for review. I think I wanted about 10 or so.

As for the most compact high quality meter
The new EEVblog BM235 would have to be a contender (biased), and maybe this one *cough* (double biased)

Ohh, is this the first picture (for non-contributors) of the custom EEVblog meter?
That looks REALLY nice! When will the official reveal be?

The Fluke 117 is quite compact when compared to other Flukes, and it is True RMS.

As a compact and high quality True RMS meter, the Fluke 115 (140$), if 1mA max resolution is acceptable.
Next, the Hioki DT4252 (140$), for the same reasons and caveat.
In third place, the Brymen 257 (135$), good all rounder, but 1 year warranty only, which doesn't inspire confidence for a high quality meter.
Next, the Brymen 235 (100$), low RMS bandwidth, but acceptable if price is the overriding factor.

For immediate buying:
BK Precision 2712 reduced at Amazon, 80$. Not the highest quality, but perhaps a good deal for some.

I have saved only two of the seven UNI-T meters I looked at.   The UT90A because it can play music and was not totally damaged during my evaluation of it and this one.   

IMO, this is one of the most useful products UNI-T offers.  It's cheap.  Really cheap for what it does.  It works fairly well as a standalone probe and in a few weeks, maybe we can add an output to drive a scope with it.

I am waiting on the second one to become available and looking forward to seeing how it stacks up.

Well it had better stack up better than this one:  ;D

It can play music? I have to see that :p

I have a UT 71C and it was worth every penny, yeah they aren't the best, but bang for buck, I think they are pretty darn good contenders. I spent a long time looking at affordable ones that wouldn't be used for mains, and uni-t seems to pretty much be the most feature packed brand that isn't crazy expensive.

I personally am not too concerned with using hand held meters on the mains myself.   Even in the rare cases where I am on mains with a hand held, it's CAT II and below.   But I do my fair share of playing with low energy high voltages.

joeqsmith.......so you just hook it to an audio source and it can play it? What is the lowest signal amplitude it can reproduce?

Ok, what is the smallest available TRMS meter? I guess all 0660L-based meters have AC-only TRMS, so my first guess it would be some HIOKI model lacking any current range, which is really sad. There were some analog TRMS meters in the 60-ies (electrodynamic), but they unobtanium now and have rather bad sensitivity, and I've never seen really compact ones.

I had measured the minimum pulse width required to get the meter to beep and the maximum frequency it could detect.   The audio is first filtered, then fed to a zero cross detector.  This then drove a one-shot the then drove the meter's input.   The one-shot had a shorter pulse time than the minimum width required to make the meter beep.   Basically, this would cause the meter to click.   So what you are hearing are these clicks.   My choice of music was not random.  Low frequency is a problem using this technique and I needed something with a lot of high frequency content.
