AC Current Measurement Calibration (HP 66332A only)

Action

Display

26.Disconnect all loads from the dc source. Make sure the mode switch on the rear panel is set to Normal.

27. Press Shift Cal, scroll to CAL CURR MEAS AC, and press Enter.

CAL:CURR:MEAS AC

28.Wait for the dc source to compute the ac current calibration constant. The display returns to Meter mode when the calculation is complete.

Saving the Calibration Constants

WARNING: Storing calibration constants overwrites the existing ones in non-volatile memory. If you are not sure you want to permanently store the new constants, omit this step. The dc source calibration will then remain unchanged.
