Thank you, Pete. I have received an initial response from Kikusui requesting additional information about the EUT and the test setup.
I haven't looked at the waveforms yet, other than voltage. That's on the docket. Regarding the matter of scale, (as I'm sure you're aware) the Simpson 228 uses multiple measurement networks and was the first commercially available leakage current meter to address UL 1459 requirements. The Burn Hazard setting (corresponding to 61010-1, Figure A.3, and the Kikusui TOS3200, Network A) is 100 mA full scale and I am trying to measure current below 1 mA. For shock hazard (Let Go and Reaction), the scale is OK.
