>Hi Jerry, one of the BIG problems is making accurate measurements of
input/output power to/from a device or machine. This problem is all the
more difficult when high frequency, spikey, or generally odd waveforms are
present. House power meters are great at measuring nice neat sinusoidal
waveforms at relatively low frequencies. They'de freak out at some of the
waveforms I've used in the past!
