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).
