Rigol DP832 - Firmware list and bugs
garrettm:
Well here it is folks. I think you'll be pleased at how simple it is to use if you give it a try. A full calibration for volts + current on all three channel takes about 30 minutes to complete. That's with a 4 second settling time and pausing to move the banana plugs between channels on the PSU and DMM as needed. And can be speed up if you lower the settling time to 2 or 3 seconds. Though I didn't set that as a parameter that can be configured yet.
I should point out that I haven't tested the manual current calibration. It should work, but if its too clunky let me know and I'll try improving it. Otherwise its pretty streamlined. You have multiple chances to escape before it actually sends any commands to clear the cal constants and lets you pick calibrating one or both parameters per channel.
Let me know what you think, or if there are any bugs. I think I squashed them all for the automated data entry routines, but you never know.
UPDATE: Removed old script. See Reply #704 for new version.

I can run up Windows 10 Powershell and Telnet to my instruments from there (first you have to enable Telnet in your copy of Win 10, it's disabled by default) and issue 1-off commands but the bit I'm missing is how to do this in a script form. And maybe this is nothing to do with Python? Maybe we need to install some sort of Python App and run Py Telnet scripts from there?

Your 34461A should work if you use the script I uploaded. Java handles the two Telnet connections and the code follows the calibration routine outlined by TooOldForThis. You would only need to find out the port value used by the 34461A and edit that line in the .java file (its not a parameter in the script yet). Then check that the DMM commands will work with your DMM. Fluke/Tektronix say they used the 34401 SCPI commands for the DMM4050, but double check. If not, just modify the string commands in the DMM methods (very simple to do). Then compile the modified .java to .class by running "javac *.java" in PowerShell. Next log into your home router and look at the DHCP table to find the addresses of the PSU and DMM (make sure to enable DHCP on each instrument first), or assign them static addresses that match the rest of the network. Then just run "java TelnetCal" in PowerShell.

I made a few minor improvements to the readability of the prompts and added some .bat files for quickly compiling and running from the command prompt instead of PowerShell. Everything should be pretty easy to use and I've incuded all the documentation needed for someone to get it up and going. Have fun.

Gandalf_Sr:
Is there a way to backup/save the calibration on the DP832? I want to try the automated calibration process but I'm worried that I will screw up and make it worse or even unusable.

If it does then just do it through the the front buttons
