Hi, i got a two Peaktech 1885 with some issues.
They are the same like BK Precision 1697.
Does anybody have some schematics for this or the other "Family" Models (BK 1696, 1698 / Peaktech 1890)?
The first Peaktech has no output anymore (no voltage at the bananaplugs, i think the output "switch" (thought is would be an relais but looks like a transistor) is broken).
The second is constantly 3V above the programmed output voltage. But it is not possible to calibrate it with the internal Pots mentioned in the Manual. I think a reference is broken...
It would be nice if somebody has the schematic or maybe repaired already one or both of the mentioned issues...?
