--- Quote from: diodak on December 12, 2018, 05:57:37 pm ---For me it was important information but I did not find it. Well, in the 30V version, the integrated circuits responsible for setting and reading the voltage and current are AD7782 and DAC8562. Unfortunately, I have no information on how to calibrate this power supply in the future...

--- End quote ---
They are a closed box calibration, in that PC scripts and a universal calibrator are needed to program the PSU's internal calibration settings.
More info on this matter is available here:

diodak:
So I will wait for service manual ... I think that the calibration will not be particularly difficult. Probably like in other devices, i.e. based on two voltage and current points. Possibly, there may be a zero offset.

Bug fixes for both models.

BillB:
It would be nice if they enumerated the bugs they actually fixed in the release notes rather than just "fixed some bugs".  I haven't noticed any buggy behavior on my SPD1168X's really, but I guess I'll update them anyway.   :-//

Update performed, no problems.
