Good clamp meter for low DC currents
KlausF:
After 2 years, my UNI-T 210E suddenly does not function any longer, DC amps is defective, I would say for no reason. It was rarely used and if it is was, then only indoor and for low currents. Cheap Owon CP2100 looks like UT210E, I want something better. Any suggestions ? What would be a good alternative for let´s say up to 400 bucks ?
I was about to get me a Benning CM 11, but its "performance" is not what I am looking for.

I have not looked at the video, but in my experience it is way better at low current then the 210E (I have both).
For clamp meters I have two groups: Low DC current and general purpose. CM11 wins in low DC current, but for general purpose it lacks high current ranges. Because I work with electronic I mostly need low DC current measurements, this makes CM11 my favorite clamp meter.

I looked at it, a bit hair-raisingly done...
The biggest disadvantage of the CM11 is that you have to be very careful not to overrun it in terms of current.
If you keep this in mind, it is very suitable for small currents.

I have still not looked at it, but if the issue is that the clamp get magnetized at higher current, I do not see that as a serious issue.
I played a bit with it here: https://lygte-info.dk/info/DMMClampDemag%20UK.html

First, a mixed current is measured (direct rectification without an electrolytic capacitor) and it is wondered why the display jumps back and forth.
Then at some point the CM11 is connected between a load and the supply and it is criticized that it is reasonably accurate - with regard to the values displayed at the load and the supply and other errors.
A somewhat adventurous "review".
