Rigol DP832 - Firmware list and bugs
H.O:
For the 34461A the SCPI command for switching to 10A current measurment seems to be
--- Code: ---CONF:CURR:DC 10
--- End code ---
And the manual states that selecting the 10A range (as above) automatically switches the input to the 10A terminal. Otherwise, the command to do that seems to be
--- Code: ---SENS:CURR:DC:TERM 10
--- End code ---

Thanks for the info. I think I'm going to leave it alone for a while, I've been testing volts and current on all 3 channels and they are all super-accurate now :)
I had my 34461A calibrated a few months back and my DMMcheckplus calibration output of 5.0000 volts displays at 5.00001 Volts on the 34461A. My DP832A set to 5.000V now displays 4.999 on the DP832A and 4.99996 on the 34461A :D

@JDubU
Can you tell me where SCPI parameters for current measure are set in script ? (DC:CURRENT:...) . Or where script switch DMM from voltage to current ...
Thank you !

In the file DP832Cal.py:
The calibration parameters for current are at the top of the file:
cal_daci12 = [0.1, 0.25, 0.5, 0.8, 1, 1.25, 1.5, 1.75, 1.9, 2.15, 2.35, 2.5, 2.75,
3, 3.2];
cal_adci12 = [0, 0.01, 0.1, 1, 2, 3, 3.2];
These are used at the bottom of the file in the Calibrate() method.
Do a search for the comment: "# Current".

Here's a picture of my calibrated DP832(A) sending 5.000V to my 34461A :D
