No proper Output Current Calibration on DPS 5015

[humaniac]

Hello profi-max,

first of all, thank you very much for your great work and for making it available free of charge.
I have two DPS 5015 that I have flashed to the new firmware 4.4.
Everything worked smoothly with the first DPS 5015.
With the second one I have massive difficulties with the calibration of the output current. Although I have proceeded strictly according to the instructions, a residual current of 0.1 A always remains on the display, even when the output is open.
I have repeated the process several times, also with different hardware versions 1.0 and 2.0. Unfortunately without success. The ADC value for “I out L” looks strange. It always remains at 0, even after repeating the calibration several times.
Any ideas what’s going wrong?

Best regards
Philip
