I'm trying to find out what current my space heater uses. Says 1500
watts; that's about 12A. I have a clamp-on current meter. Is there a
trick to using one of these on a power cord or do you have to have
some kind of adapter to split the power cord lines?

Any way to do this to make it simple? I have some other thinfs, like a
radio, that I'd like to measure too. (Trying to run my space heater
and a radio off the same receptacle.)

TIA



Using line splitter, I found my Ideal Split-Jaw Smart-Meter clamp-on
meter will not read less than 0.6 A. so can't measure my radios' curret
usage, but measured the heater's 12.5 A OK. I think it is around 500 mA.
Ideal is the first eter I've had that had a minimum measurement cut-off.
I can unerstand maximum but...

I think my UEI goes down to .1a but to be frank, if the current is
that low I really do not care. If I was really interested at that
point I would use my Kill a Watt or the Fluke "in line" meter that
gets down to 100s of micro amps.
You will also find a radio or anything else with an amp in it responds
to the volume control. The louder it is the more current it draws.
