Verification and Calibration

Introduction

This appendix includes verification and calibration procedures for the Agilent 6814B/6834B/6843A AC Power Solutions. Instructions are given for performing the procedures either from the front panel or from a controller over the GPIB.

The verification procedures do not check all the operating parameters, but verify that the ac source is performing properly. Performance Tests, which check all the specifications of the ac source, are given in the applicable ac source Service Manual.

Because the output of the ac source must be enabled during verification or calibration, proceed with caution, since voltages and currents will be active at the output terminals.

Important Perform the verification procedures before calibrating your ac source. If the ac source passes the verification procedures, the unit is operating within its calibration limits and does not need to be recalibrated.

WARNING LETHAL VOLTAGES. Ac sources can supply 424 V peak at their output. DEATH on contact may result if the output terminals or circuits connected to the output are touched when power is applied. These procedures must be performed by a qualified electronics technician or engineer trained on this equipment.
