You may get better - different - results if you use an oscilloscope to
measure this voltage peak. The Simpson has ?dampening? qualities and will
NOT show the true peak voltage/current.

 

Also, have you taken into account any internal resistance of the Simpson? As
I recall that was a 20,000 ohms per volt (a 50 uA movement) meter - Great at
the time, but worthless today for anything other than house/auto wiring -
which also implies that there is a shunt dropping the meter movement down
from 50 to 60 (???? which model has a range of 60??? I have seen ones with
50 and 100 uA but not 60) and thus there is resistance added to your "test"
circuit. These small errors are acting like a furculum and greatly skewing
your results.
