Bob, I'm getting ready to work on implementing what you suggested.
Could you take a look at this sketch to see if this is what you are suggesting for hooking up the oscilloscope? http://www.lenr-coldfusion.com/wp-content/uploads/2014/08/power-measurement.png I won't be able to do 10 amps for calibration, but I can do anything up to 5 amps with my lab power supply.
