My Hantek2c42 often doesn't pass the calibration. It freezes on it! I wait for more then 5 min, nothing changed.
Only way is return and try again. Some times it pass at 2 or 3 time.
How to fix it?
A problem also with DMM. In "DC mA" is not zero even when i cross the probes. It always show 0.02-0.05 mA, without probes also.
How to fix it?
Also i want to ask to make some changes in the new firmware.
1. Add Menu hide on second pressing "Menu", "Trig", "Channel", "Time", or on pressing "Enter".
2. In "Trigger" mode change buttons "<" and ">" form changing trigger level to changing trigger position, like it does in "Time" menu.
3. Add horizontal scale settings during operation. At least option to see all the signal on the screen but not a part of it!
4. Not to draw voltage settings of the channel when it is deactivated.
5. Make working icon about channel coupling AC,DC, Gnd. (~,–,x)
6. When menu is hidden. Make changing of arrow buttons usage: "F1" - CH1 changing, "F2" - CH2 changing, "F3" - trigger changing, "F4" - time changing. Without showing this menu! Only arrow buttons function changing!
