Hi,
I habe a HP6140A Precision Current Source which requires some care and adjustment.
Does anybody have a well readable Op-and Service-manual? I just got a scanned version, with quite difficult to recognize schematics and pics.
Also I´d like to have infos/manual about the associated optional Programmer HP14533B.
Seemingly it was just a bunch of switches and a single momentary button, as well as a couple of LEDs?
Thank You in advance
Calvin
