My Clamp meter conundrum - Quality Clamp meter to match the cheap Uni-T 210E
<< < (5/7) > >>
Neutrion:
Thanks, but all these only go it seems down to 0,01 A resolution while the UT-210e goes to 0,001 A.

Mine now has a drift (not in time) which increases linearly from zero up to about 0,150-0,200 A in the smallest range.(And in similar proportions in the rest of the amps range.)  So it has this problem immediately I don't have to wait.  Around a few miliamps level it is accurate.
There is a video on Youtube how to compensate exactly this type of problem with a proper calibration.
Not sure whether other brands with high DC resolution also have this.

I will give this a look. But Dave himself pickup on a design flaw with the Uni-T plastic part that the clamp spring pushes against. And sure, enough on mine that plastic is broken. After a while you just get annoyed with flimsy gear and end up as going crazy and mad like me looking for a quality replacement.

Yes it is. In my oppinion it is not so easy to brake the clamp. Mine is OK, and doesn't seems to be flimsy.

General Tools CM700 maybe?
Kleinstein:
DC clamp meters for small currents are a bit tricky.  There are 2 principle problems: one is that external magentic fields that can have an effect. The other is that there can be remanent magnization in the core, e.g. from high DC current in earlier use, especially if powered off or over range. The may requite some demagnization (e.g. use with a significant AC current that is slowly turned down).
DaneLaw:
The unit-T 210E is of surprisingly decent build-quality with the price in mind..
My unit is quite old, and had no problems whatsoever with the build-quality.. find it sturdy and rigid.
if you hand out many hundreds of dollars for a low current AC&DC clamp meter, you will hopefully get a better build than a 30-buck AC&DC clamp meter like 210E or will you?

You should purchase an Extech MA63-N  ;)  a steal at 410 USD before AU VAT..

Or you can keep it lowkey and jump on the cheaper non-third-party-calibrated MA63 at merely 580 AUS at Amazon.au - and keep the Unit-t 210E/211B vibe going under a big-brand label with a hz added-price to match and then you can talk about a conundrum.
