Yes, it works now, congratulations and thank you so much!
There is still a problem with the display of channels A and B (but no crash). Both channels are grounded, the problem happens with the short as well as with the long buffer:
- in AUTO and SCAN modes, I have huge offsets on A (e.g. 6 V on a 2V/div scale)
- In SCAN, short buffer, sometimes it refreshes the screen several times per second with a 1s time base (!) and trigs on a square impuls of 6V (2V/div) and 1div long (synchron on both channels) - with grounded inputs…
Marco’s firmware does not show this behaviour.

PS: when using the 10x mode, the readings on the right (Vrms and so on) are correctly multiplied by 10, but in the menu (second line), the voltage display is not. E.g. CH(A) / DC 2V, then when I chose 10x(A) I would expect “DC 20V” and not “DC 2V”. Do you understand why?
