Rigol DP832 - Firmware list and bugs
IAmBack:
Hi.
First few with new DP832 minutes and BUG!!! (or failure).
In mine brand new psu OCP in channels 2 and 3 works only ONCE - ie. in the case of shortcut it turns off channel, as expected. But when the next shortcut appears, OCP acts as a current limit (reduces current without switching channel off). Even the best known method of computer specialists (turn it off and on) doesn't help - I need to change OCP limit setting to re-activate for another SINGLE action, but it not always works.
Channel 1 works fine.
Can anyone replicate that, or I have to send this psu back?
H.O:
Just tried it here on my 2013 vintage DP832 with firmware version 1.11 and it seems to work fine on all three channels.
Which firmware version are you running?
TurboTom:
@IAmBack
On mine, OCP is working as expected (repeatedly) on all channels. F/W 01.14.00.03, Analog Board Top/Bottom both 02.02.04, Boot 01.09, Keyboard 01.01, all options "liberated" ;), factory calibration from 2015/11/21.
Cheers,
Tom

Test performed on channel 2. Does not work.

TurboTom:
Okay, I replicated your settings on my DP832 and the OCP worked everytime. It automatically is rearmed when the output is activated.
I recommend to update the firmware of your power supply to the current version (01.14), maybe your finding is a bug that Rigol eliminated with the update.
Cheers,
Tom
