--  Put a 5 to 10  meg-ohm R in series with a uA meter in series with 
the high-pot tester.  Connect to the device under test (DUT) and slowly 
increase V until a reverse current of c. 5uA flows.  Stop increasing V 
and record it.  This is what going on in pic20 in the Class A amplifier 
project on my Web site.
