Good clamp meter for low DC currents
<< < (12/15) > >>
BILLPOD:
Anyone got a BT version care to comment? Yes I know BT has issues too but it is what it is.

I have recently acquired the OWON and have been comparing it with my 210e, and they are pretty much equal in accuracy, (DC current is all I  have been comparing).   However, the Owon has the bluetooth, which I love, and the android software is nice to use.   But, as with the bluetooth on any of my other meters, the range is poor, but better than my Mooshimeter.

You really do have to consider ALL external sources of magnetic fields, but developing a technique and using the "zero" button has proven to give reasonably repeatable measurements.

Just tested out of curiousity the effect of current-carrying wires outside of the jaws: (Owon CM2100)

Conductor carrying 20A current causes visible 2mA error if closer than apprx 100mm to clamp end. If placed next to jaw opening the error is up to 50mA. Something to keep in mind if working in a crowded electrical cabinet or car wiring harness.

This topic is about "clamps meter for low DC currents" and the OP was asking about "mA and uA" measurements.

The UT204A has 40A and 600A ranges.  So the UT204A is not really applicable... unless you know something we don't...

That is good, 0.01% error at 10cm is not much. In praxis you would not have 20A next to a clamp measuring mA. Except if you want to measure sensitivity, or you are a bit stupid (Sorry, but that is my opinion).

I have not seen any errors on the CM11, but I only use it to measure low DC currents (That was what I bought it for and it do it very well).

Can you check your CM11 to see if it has the same issues as the one in the video?
