HP 34401A AC CURRENT CALIBRATION?
« on: July 20, 2016, 07:22:57 pm »
I have a 34401A meter that appears to be well calibrated in DCV, DCI and ACV modes, however in ACI mode there is a healthy offset of about 40ma.

Reading the calibration procedure it implies that you have to calibrate all offsets, and the ACI calibration procedure is missing from the procedure. I'm not sure if there is no ACI calibration and that the meter might rely on the DC calibration when used in AC current mode.

Does anyone have any insight into ACI calibration?
