I just upgraded my DP832 to 00.01.14.00.03, and started doing a manual calibration. Once it got to a step (in the many steps of manual cal) where it outputs more than what my previous/current OVP setting was (16.8V), it flicks the channel off with the OVP modal-warning.
So I curse the firmware Dogs, save my cals, back out to normal operation, set OVP to max (33.0V) and disable it for good measure.
Now every time I turn
off CH1 the modal-warning comes up to say OV-protection's disabled the channel
Indeed, sticking the DMM over it, it's up at the channel's max, 33.x V, bouncing off & on & off & on.
If I stick a light load on the output (circa: hundreds of ohms) it'll settle down to some intermediary V (e.g. 10.x V with a 220ohm load).
Rebooting changes nothing.
It would seem it's not fully disabling its output, and the built-in OV-protection (not the user-settable one) is naturally triggering.
Any ideas?
