content: "UR" is described in the manual, page 2-2, asQuoteI can't see why it would say that from what is shown on the screen. Setting mine to the same as shown on your screen it seems normal, do you have anything attached to CH1?

content: No, the channel ch1 nothing is connected.The CH2 and CH3 work very well.In the CH1 not out the current!I recently had a power surge.I get the impression that I have broken some control or end of CH1.Is there a schematic of DP800?I do not have the guarantee.

content: I take it you have tried a complete power down and restart?Might be worth a firmware update, can't really hurt at this stage as you have a 832A, it contains new code for all the boards. Unless you are on the current version already that is.Details inhttps://www.eevblog.com/forum/testgear/rigol-dp832-power-supply-firmware-upgrade/30/I put a copy of the software and instructions up on my dropbox account,https://dl.dropboxusercontent.com/u/18258697/DP832A%20Firmware.zip

content: We'll it was worth a try.Rigol in the EU offers a 3 year warranty, assuming it's less then 3 years old it might be worth sending them an email. There is a contact us onhttp://eu.rigol.comDave's teardown videos of the 800 series might give you a clue as to where to look too.
