Do clamp-on ammeters even work on DC current? I thought they were AC only. I thought the flux field around the wire was all they could measure and to measure DC, you have to have a shunt. Wow... a DC clamp-on would indeed be a cool tool to have.

AC clamp-on works like a transformer. DC clamp-on uses a Hall Effect device to sense the static magnetic field caused by DC current flow.
But beware, according to the "experts" in previous posts it's a totally worthless device.

See... it's you "round earth" types and yer new-fangled "hall effect" theories that have put bell-buzzer manufacturers around the world out of business.

This is more of a voltmeter and results are about binary, but it does ok. Only Gene Simmons could test my house bank, though.

Where did someone say that? I called it an "invaluable" "essential" device myself.
I just hadn't seen the clamp on used as a tracer and was interested how it was done. Sorry if somehow that was of offense. Otherwise, I think we may be violently agreeing with each other.

I bought one to track currents in the wiring mishmash the PO left, but being an absolute green horn in electrical stuff I really am glad to pick up useful tips like this anywhere I can. Thanks for putting the original post out there.
