With chopped DC, a clamp on ammeter will show the AC component. So if 
you had 0 to 1 amp chopped, the ammeter would show 0.5 amps peak AC. So 
you get a partial reading, substantially less than the true current that 
is actually flowing. IMHO, this could have happened at the demo. I am 
not saying that it did (I was not there), merely that it could have.

What would the clamp on meter show with chopped DC?
