Verification procedures verify that the power supply is operating
normally and is within published specifications. There are two types
of verification tests:
These tests verify that the power supply meets all of the specifications listed
in Appendix A. They can also be used to verify that the power supply is
properly calibrated.
These procedures calibrate the power supply.
If the power supply fails any of the tests or if abnormal test results
are obtained, try calibrating the unit. If calibration is unsuccessful,
return the unit to an Agilent Technologies repair facility (see
Appendix D).
The equipment listed in the following table, or the equivalent to this
equipment, is required for the calibration and performance tests. A
test record sheet may be found at the back of this section.
