Title: DP811A ( DP800 ) SCPI Command Calibration for PC
Post by: cidak on October 31, 2014, 10:45:44 pm
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.   :-BROKE 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. :palm:

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.  >:D

 :-/O Someone SCPI commands for calibration, or any other solution to seat the power supply?  :-DMM

THANKS!  :)

Hello cidak,
    Use the SCPI calibration instructions posted   Here (https://www.eevblog.com/forum/testgear/rigol-dp832-firmware-updates-and-bug-list/msg556101)
 
They should work on the DP811A too.  But the DP811A has different calibration points.  Use the cal points in the document I attached.

The DP811A can output 10.5Amps.   So unless you have a real brute for a DMM, you'll have to measure the upper current ranges by measuring the voltage across a low impedance power resister attached between the + and - terminals.

  :clap: Thank you very much for providing information on how to calibrate  :bullshit: the DP811A Power Supplies.

I for one appreciate this very much
, and I'm sure everyone else here does also. :-+
