Hello, I had a account from yahoo groups agilent and I recently transferred over.
I have a HP 6012B which I successfully repaired the current potentiometer so no more issue with the supply going full 60 amps with the slightest turn of the knob.
However I have some minor calibration issues if anyone could assist. I notice the volts on the display will not go below 0.2-0.1 volts at the full counter clockwise position, it also reads the same on the voltmeter. I am studying the manual to see where those adjustments are.
Also, when I test the amperage control by using a light bulb and a voltmeter in parallel to measure the current, if I set the current to 4 amps and quickly ramp the voltage the current peaks at 5 amps briefly before going back down to 4 amps a fraction of a second later. Could this be a typical overshoot characteristic of this supply?
Thanks
