Appendix B Verification and Calibration

Verification

 

Verification procedures verify that the power supply is operating

 

normally and is within published specifications. There are two types

 

of verification tests:

Performance

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.

Calibration

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).

Equipment Required

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.
