Yes same mine upgraded and lost trigger but calibration I think not necessary I done because changed also lm317 now not 5.14v but 5.088v also to try fix ch2 which read 9mV up than real still now if you make calibration make sure wait 3,4 seconds before confirm insert value on adcv and adca calibration
Can you supply the calibration guide to us? Or show the location where to download?
I done full calibration now works well very accurate Voltage and Current like 12.000v I read 12.000v with Agilent DMM no reset with switching mod my 5v board keep 35c max, is important you make erase calibration with command via Ultra Sigma sw no matter if you don't get answer just send command like in calibration guide and after start calibration for each channel my fw is 1.08 lost only Trigger.
In picture an engineer from Rigol testing my work with 34461A :-)
checked now what installed on pc I is 00.01.05.10 I take from Rigol website when you have send both command listed on manual you see adc voltage feedback going out of spec and you can procede with manual calibration

Do you mean the SCPI commands?
:Cal:Start 2012,CH1
:Cal:Clear CH1,ALL
If so, I cannot get those to work.
You mentioned "erase", what exact command did you send
and on which screen please?
Thankyou
I sent a polite email to "info@rigol.com" last night stating the timeline of my issue and asking for either a fix or at least information on when the fix would be offered. I received an email back a few hours ago from a gentleman at Rigol who sent an RMA form and a pre-paid return shipping tag. He mentioned they had been kept waiting for the repair parts, and that it was taking time to work through the backlog of units for repair.
At least it appears they are now performing the fixes - hopefully the turnaround time won't be too bad. I have other supplies I can use so I won't miss this one for a couple of weeks, but I hope it doesn't end up taking a couple months. I don't think it will - they told me they should be able to turn it quick.
So for anyone still waiting, I guess you could either wait for contact knowing they are doing fixes, or you could email info@rigol.com and ask them to ensure you are on the list, at least.
Hope it helps.

Any update on this? I wonder if you sent your DP832 back for the board replacement? If so, have you got it back yet? How has the correspondence been from Rigol NA about the process?
Thanks!
Funny you mention that - I actually haven't sent it back yet, but I plan to this week. Literally the day I got the shipping tag, a little emergency project fell into my lap using some white COB LED's that take over 30 volts. I needed my DP832 to run these reliably so I figured I will send it when I am done. I wrapped it up over the weekend and should get the unit out tomorrow.
I sent them three photos, one with the first topology of LM317 that the two capacitors and LM are very closely (I call this "First Board Revision"), the second with the movement of capacitors and LM317 (I call this "Second Board Revision") and the last that we call Revision 2.1 with the big heatshink (I call this "Third Board Revision").
The answer of Rigol about this was : the first picture you send ("First Board Revision")are from the board Rev. V2.0, the others two are from the board Rev. 2.1, so no need to change ! On the old Rev ("First Board Revision") the heatsink is directly located next to 2 brown C’s.
Not the Size of the heatsink is important – the location is important – Also on the port is written which version it is.
From what I understand from this answer is that the last two versions that we have captured ("Second Board Revision", "Third Board Revision"), are from the same Top Board Revision (2.1) and the only Top Board that they changed under the warranty is only the Revision 2.0 ("First Board Revision").
Have you any other information about this?
I know, "use the search".
Anyone here willing to summarize where the Rigol DP832 stands with respect to feature and performance issues?
(Despite the issues I'd like to purchase a 832 but I'm not in a hurry and I'm inclined to hold off until these are sorted out - assuming Rigol will get around to them).
Any updates on the following? (have any of these been fixed in new shipping units?):
turn-on spike
overheating
intermittent restart
channel 2/3 cross connect
below 10mA software
any other notable issues
Thanks, EF
