John,

I have a question about power meters, I would like to do some
consumption monitoring at my house. I see the cheap plug in meters and
the $500 Fluke recording multimeters. Is there anything in between? I
would like to measure on some 220V appliances and I don;t think that
the plug in ones will do it. Any advice?

Thanks,
Kev

FWIW, Harbor Freight has some really cheap, serviceable clamp-on
ammeters. They won't give you all the information a wattmeter would
(especially when power factor is important) but they can nonetheless
give you some pretty good clues at very low cost.

Can the clamp-on ammeter be used without separating wires?
