I don't think it's clear that the test would be better or worse --- only that the presence of an additional ground cable in the test set-up may have an effect on the outcome...

In case of dispute, a test with the cable disconnected during ESD pulse takes precendence over the test with the cable installed during the test." Anybody know the phenomenon of that influence? Does it mean that testing with bleeder resistor can give worse result than testing without one? Thanks in advance Kyaw
