Hello!
Recently i got i non-working Agilent E3634a power supply and now had some time to start (or better try) repairing it.
Self-test on start-up shows Error 632 which indicates a failure in HW according to the manual:
632 Hardware test failed This test checks the status of voltage and current error
amplifiers for the power circuit. If both amplifiers are not operational, the
power supply will beep and the error annunciator will be on.
Display shows 53,759V / 6,799A. Measured Output voltage is around 0,68V with OR without output enabled.
A first optical inspection shows no burned/damaged parts.
Does anyone have a good advice where to start or what could be damaged?
Regards
Marco
