Dear amy
Worked very well, i thank you again.
It looks like the crashes are gone now, that's great.
What is still there is a permanent Y offset on both channels after automatic calibration.
It looks like it's the same percentage with each Y scale, the graph looks the same with each Y scale but the measured values are changeing.
Therefore i guess it's caused by an ADC offset, in my case about +12% on CH1 and -12% on CH2 if i do the calibration with connected power inlet or about +20% on CH1 and ok on CH2 without power inlet.
I beg you to find a way to adjust that either manually or automatically, it's really anoying to have such a difference at the core values of a device that even rises if you enlarge the Y scaling of a hold measurement.
Best regards
