Rigol DP832 - Firmware list and bugs
McBryce:
I just updated my DP832 to 1.14 (file above) from 1.11. My bootloader was already 1.09 so I assume I didn't need to update that. All went well including updating the two analogue boards. However after all was finished and I had restarted, the DP832 had a spontaneous reboot about 10 minutes later (I wasn't pressing any buttons at the time, CH1 was ON but nothing connected to it). It hasn't happened since then (been using it for 30 minutes since then). Has anyone else experienced this? Or noticed any reduced stability since upgrading? I've never had this happen with 1.11

P.s. All "liberated" options are still present after the update.

I just received a DP832 on which the firmware 1.11 runs. What bothers me is the fan control. While the PSU is booting up, the fans run on slow speed. But after booting up the fan speed increases and they never slow down again, even when the output is off. As a result they are quite noisy.
Shouldn't they slow down again?
McBryce:
That's wierd, it should do the exact opposite. Mine starts on full blast (expected as the software hasn't started fully yet) and then slows back down when it has fully booted and being regulated.

Maybe the weird behaviour I have described above is a result of the wrong temperature readings in the firmware 1.09 and 1.11. Since you seem to be an expert regarding the DP832, I guess you run the latest firmware. Maybe I should update.
McBryce:
I'm definitely NOT an expert on the DP832 :D I just own one. Up to today I had being using 1.11 and didn't have that problem. I only updated to 1.14 tonight.
