KORAD 3005P, calibration?

(1/2) > >>

MikeK:
I found that mine outputs 0.51mA even with the output switched OFF.  And when set to 5mA it actually outputs 7.8mA.  Ugh.

I checked the user manual, but no info.  Can this be calibrated?  At the very least OFF should be OFF!

Electro Fan:
Here is a link to a post with an old calibration routine - there might be a newer one or one with better translation.

SHF:
I have something here in German

MikeK:
Is having 0.51mA with the output Off even a calibration issue?  Why would there be any current at all?  An output transistor leaking current?

Forester:
I have a KORAD 3010. When the output is off, the voltage is 6 mV,  сurrent 3.6 mA. Measured Fluke 87V. Why so - I do not know.
