Perfectly.

I believe I saw a vid where someone tested it, and the meter survived (as many decent DMMs do). Don't quote me on this though, better search yourself -- there has to be a lot of vids showing transient protection, user error protection etc.

There's also vids of people hooking them up to machines and turning the selector switch 100,000 times then looking for wear under a microscope.

Result: A Brymen is as good as a Fluke.

(And Keysights fall apart after a couple of thousand turns)

Not exactly any. A counterexample is a super cheap Uni-T UT33A+, which has a usable 2 nF range.

Watch around 3:35:



I don't know for sure, but it can't be the only DMM with a low-nF capacitance range.

Yes, but that's irrelevant to not having a sufficiently low range.

Oooh, Joe's here...

Just to be clear, that's 50,000 times to the far end of the dial then 50,000 times back again.

Superb, next meter will be a Brymen. That's if the Fluke fails because I don't need that many meters.
