Calibrate HP 6612C ?

[JohnPi]

I'm trying to calibrate my 6612C System Power Supply.

I'm being lazy and not connecting to the rear force/sense terminals -- just until I can prove to my self that I can calibrate, then I'll use those.

I can get into Cal mode (via the front panel, or GPIB) and calibrate the voltage and high current range. However when I enter the CAL:LEVEL P1 and then CAL:DATA data value, I get an OUT OF RANGE ERROR. The calibration setup shows to use a 400 ohm R in series with an ammeter -- so it seems that the precise value of the 400 ohm can't be that critical -- I get about 40 mA. No matter whether I enter the value as 0.040, or 40.0, I still get that error.

Any ideas/help ?

Sure, you need to read manual more carefully and use correct resistor.

Carefully read Table B-1, and read what is inside the rectangle below Figure B-1 B.  For calibrating the low current range, it's supposed to be a 1.1 kOhm resistor.  The 400 Ohm is for verification.

My first attempt to calibrate my 6612C also failed.
But if I remember right, there was a mistake in one of the steps and one ENTER step was missing in the instructions. This becomes obvious, if you follow it. At the end it worked all out for me.
