Rigol DP832 - Firmware list and bugs
milow:
Thanks a lot for this piece of information. I've seen your name on some posts related to the DP832, hence I assumed you are quite familiar with it. I compared my supply to others ones the net. Here your see a "normal" unit:
There a three phases of tfan speed:
1. slow speed when booting up
2. rather high fan speed when the screen with the voltage settings shows up
3. slow speed after a few seconds
Unfortunately, my unit never reaches phase 3 but stays in phase 2. Thus, the fan speed remains high.
McBryce:
In the Test/Cal menu it gives a Temperature and Fan status, have you checked what yours says?

milow:
Of course I've checked that. It says that the fans are working and the temperature is about 12 (without unit). The temperature bug is already described for the firmware 1.09/1.11. But since you've said that the fan control is on 1.11 without a problem, I think the wrong temperature is not the reason.
Does your unit have the 3 phases of fan speed (low while booting, fast for a few seconds, low again)?

I think so, but I'll have to check again when I am back home.
McBryce.
Edit: Yes, three phases - Medium (until the dots under Rigol have completed), Fast for a few seconds after the 3 channels screen is shown and then the fan ramps down.

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

Just had mine reboot - likely less than a minute after switching on. Channel 1 was on with a 7V 45ma load. Kinda warm and humid today - system temp was 33.23C. All latest soft/firmware
