Do you run the entire ac line hot/neutral/ground through the unit or just the hot? I like that it doesnt splice into the wire. It has a 0.40" opening for the wire. If you just run the hot through doesnt the extra space for it to move around change the reading? Ie varies the strengrth of the detected magnetic field? How acurate is it? Is this true? "When you convert a AC to DC by a full wave rectifier bridge you have to multiply the output voltage by 1.41 to obtain the VA" If so I never knew this before:) Thanks, Mike -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
