DOH...and I was just thinking changing the date/time might work.

Skimask:
Success...after leaving it on and idling for a little over 30 hours.

So, I have a DP832 that I purchased in November from tequipment, and twice now, the unit has randomly reset on me. It's running the latest firmware, and is newer than the revision with the old crappy undersized LM317 heatsink... anyone had this happen on their unit? One of the times it did it, I thought it was due to an accidental short of the outputs, but the second time, I wasn't in my lab, and came back to the unit having it's output off... and the leads couldn't have been shorted.

Thoughts? Am I crazy, or have others seen this type of thing with their fully updated units?

Macbeth:
I've certainly seen it reset itself, and can't pin down what causes it as it is quite rare and in my case appears to have only happened when the PSU has been mains powered on and hasn't even warmed up... So far when I've left it running and come back to it a day later there have been no signs of the reset (ie. outputs switched off)

pa3bca:
I've had this once - coincidentally, last week. The unit was on for about a minute, channel 1 output enabled (5 Volt, 0.1A current limit, actual current abt 10 mA). I saw the display suddenly go off, and then the unit rebooted.
I sure hope this was a once in a (my)lifetime glitch...
