Which clamp-on meter? Many of them will only measure AC
currents, not DC.
This one does. Sears 82369.
Michael Koblic,

I took a serious look at one of those, bought it and tried it on a
lightbulb wire on my car in the parking lot. The reading was unstable
because the zero drifted too quickly. I returned it.

***I bought mine on EBay for a very low sum so I am more tolerant. However,
having said that, I was quite impressed with it. I tested it across various
ranges using fixed resistors and one of my power supplies. I tried to
multiply the readings by coiling the lead and it showed the multiples just
fine. Yes, you have to zero it before you start measuring. However, for
measuring high currents it is better than almost anything else I have had
before which had to be connected into a broken circuit. The internal
resistances usually played havoc with the voltage, however small they were.

There are quite a few more expensive ones but for someone who is happy with
the current reading within 10% this one works for me. I bought it initially
with a view to do some electroplating and found it useful incidentally when
part of the house heating died.
YMMV :-)
