Hello,
i've a problem with a power supply HP6030 with GPIB board.
The device power up and there isn't any error code.I can setup the wanted amount
output current that it should give,but when i start to move the jog immediatly
the led overrange ligth up and the voltage remian @ 0 volt.
I checked all the power section and seem to be ok.I've checked all the signal in
the connector A2J7 on A2 control board and all seem to be ok.
If i have well understood the functioning of the instrument, the
overrange(autorange) limit is calculated by the uProcessor using the Vmon and
Imon signals.
I think that the 2 signals are multiplied and the result is verified with a
value of reference that means max output power possible.
So if i mesure the Imon and Vmon in the rear of the supply or in the A2 board
they are perfecly @ zero.
So my opinion is that probably the uprocessor receive the digitalized Imon and
Vmon with a wrong value.
These signal pass trought a multiplexer and then into a A/D converter.
How could i check this part of circuit?
Or somebody had same problem and resolved it?
Thanks in advance for any help

I will have my colleague that knows these supplies very well pop in on your two posts.
Stay tuned
