Yet Another DMM Indecision Post
KungFuJosh:
I'm considering getting yet another meter. I was hoping to get something higher-end, but not sure what the best option is, especially in the lower price ranges.
My primary DMM for the past 12 years has been an Amprobe 37XR-A. It's been great for the most part, and I love that it has inductance in addition to the standards. I also have a dozen other meters including the DE-5000 and the new Shannon tweezers.
My primary uses are for electronics work on guitars, amplifiers, pro audio, and some more precise stuff like my FUtracer tube tracer. Generally speaking, I don't need 30 digits, but I do want solid performance.
If something is available with common TRMS DMM specs plus inductance, that would be awesome. I guess I want a higher accuracy / broader spec version of the 37XR-A. I always use voltage, diode, impedance & continuity, sometimes current, and capacitance, and sometimes inductance. If trying to get inductance included is unrealistic, that's fine. I'm not trying to spend thousands of dollars on a DMM. I'm not interested in paying for the Fluke name either.
These seem to be nice options from the Multimeter chart thread (and the 1000 other threads like this one), but I don't think any do inductance:
Brymen BM869
Hioki DT4282
Uni-T UT181A
CEM DT-9987
EEVblog / Brymen BM786
Does anybody have a reason why a bench model might be preferred? From my understanding, they typically cost more, take up more space, and aren't isolated because they usually use wall power.
I don't really want to spend a lot on this, so I might trade (or sell) my SDG2042X towards a nice meter. It's barely used at all (probably less than an hour total) since I got it shortly before my SDS2104XP, and then only used the built-in AWG. If I get something cheaper like the BM786 I'll just keep it.
Thanks,
Josh

Of course a bench DMM has isolated terminals, what DMM doesn't !
Isolation from mains is provided within the meter and they typically offer a rating into the reference terminal of 500V max above mains ground.

Oh, that's cool. I read somebody claiming otherwise on this site (I never bothered to research further, Oops). Ok, so the Siglent DMMs can be on the list too. 😉
I didn't see anything for inductance on those either tho.

Correct.
