Hi everyone, I'm the owner of DP811A, I installed the v1.11 firmware.
I made the calibration of the V-DAC and the I-DAC output voltages and now all wrong.
I tried for three days to redo the settings, to no avail. Then I read here on the forums that the 11.1 have a bug.
Now I have an old iron box unusable paid 750 Euros.
Someone can 'help me to solve this problem?
I contacted RIGOL EU Engineer Mr Thomas told me that I should not touch the calibration and now so I have no warranty and I have to send them by paying the repair.
To me this does not seem fair, I did not do the problem, but they did their damage with a firmware bug.
Someone SCPI commands for calibration, or any other solution to seat the power supply?
THANKS!
