As pointed out, if the DUT is not isolated and plugged into the same supply (not necessarily same socket) then you dont need the ground clip because, both are referenced to the same ground alreadyIf i don't use the O-scopes ground, it will make the signal/waveforms very noisey on the display and I can't trigger them too
At some of my jobs , techs uses an isolation transformer for their oscilloscopes , why don't u?
Because he is qualified and knows what he is talking about.
They use an isolation transformer to separate the grounds from the test fixture, power supply, variac, o-scope, etc.
Each one has it's own isolation transformers , so there is no ground loops also or grounding problems
Except one minor detail. nothing is reference to each other
