Gossen Metrawatt 32EL300R30 electronic load - measured values way off
(1/1)
rockwell:
My Gossen electronic load has the problem that the measured values shown on the display are not correct.
I opened the case and hoped that there are some labeled trim pots to adjust the measured values.
So furtunatly I found 9 trim pots, but they are all unlabelled so I don't dare to touch them and mess up all settings.
Does one know how to change this ?
Or even knows if there is a service manual around, I checked google for this but didn't find anything.

Are only the displayed values wrong?
So you have to check only the display or ist input.
Edit: OK its a newer one. Forget the displaycheck.

Yes, the voltage shown on the display is not the same as that on the input leads measured with a DMM.
It's the same device as the Atten ATZ3711A, Array 3711A and Tekpower 3711A.
