Re: Re: Voltmeters vs. Ampmeters

[Roland Dudley <cobra@cdc.hp.com>]

As I mentioned in my post, there are ways of getting around the heavy
cabling problem required for the cheapie ammeters you can buy at any
auto parts store or J.C.  Whitney.  I'd probably go for the current
sensing loop approached since it's the simplest and most passive; but
for cheapness and ease of installation, it's hard to beat a voltmeter.
You just mount it anywhere, connect one side to ground and the other
side to almost any hot wire in sight.
