(ET) Current measurement

[KevinC927 aol com]

I have been frustrated by the lack of quantitative current readings on my E-20.  It's a thing that follows scientists and engineers around, I guess, but I want numbers!  The lastest Home Power magazine has a neat article on a series of Hall Effect sensors that can be placed over a single conductor and measure current from 1 to several hundred amps.  It takes a couple of op amps and an analog meter with a calibrated scale or a digital meter.  Check it out.  The sensor manufacturer is ampsense (www.ampsense.com).
