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). |
