Hi,
I've a doubt on how work the calibration procedure:
When a make the calibration, i test voltage level (min and max) that the power supply tell me to test.
Probably there is a mismath the forst time a run the calibration, but what happen when I do the calibration procedure twice?
I tought that wasn't differences between the voltage test of PS and the voltage read by the DVM, but I always read the same voltage difference, like I never passed the calibration procedure (or when I run calibration the PS reset the voltage settings?).
Example:
PS: v lo 0.1000 v
I read on DVM: 0.1002
I set on PS: v lo 0.1002
(and so for the others)
I run again the procedure
PS: v lo 0.1000 v
I read on DVM: 0.1002 again!!!
Is this normal, or I never completed the calibration procedure?
Thanks for help.

From our investigation, Please see the answer that i provided as below;

Answer: Your the previous cal constant will not be applied when you are entering the calibration mode. so, during your 2nd calibration, the reading of the DVM and PS will always be different.

Answer: Please see above answer.

Answer: Standard calibration is... after calibrating your power supply, you need to complete the verification, you set some range of voltage, and you should read the same voltage at the DVM if you successful done your calibration.
