This is the proper snapshot when the sensor is powered on. Weird is the signal moves from top to bottom. Not smooth at one (milli-) voltage level. I dont know why.. perhaps I am a bit inexperienced on using/reading 'scopes? I'm a Python support by profession.
The reason for that is, my 'scope was in "rolling"-mode and the snapshot is the moment I pressed the ON/OFF switch.
Yes, I did using the Fnirsi lab power supply.Did you power the sensor while testing?
BTW thanks for the quick responses, I'm investigating, but not making much progress on measuring AC low-power .
