Introduction
Use the performance verification tests to verify that the unit under test (UUT) is operating normally and
meets its published specifications. Two different levels of performance verification tests are available:
l
Performance Verification Tests An extensive set of tests that are recommended as an acceptance
test when you first receive the instrument or after performing adjustments.
l
Calibration Tests These tests verify that the instrument is operating within its calibration limits.
The performance verification tests are recommended as acceptance tests when you first receive the
instrument. The acceptance test results should be compared against the instrument specifications.
Keysight Technologies recommends that you repeat the performance verification tests at every
calibration interval. This ensures that the instrument will remain within specifications for the next
calibration interval and provides the best long-term stability. Performance data measured using this
method may be used to extend future calibration intervals.
Perform the verification tests before calibrating your power supply. If the instrument passes the
verification tests, the unit is operating within its calibration limits and does not need to be calibrated.
If the instrument fails any of the tests or if abnormal test results are obtained, try calibrating the unit. If
calibration is unsuccessful, return the unit to a Keysight Technologies Service Center.
Refer to the Test Equipment and Setups section for a list of the equipment and test setups required for
verification. Also refer to the Measurement Setups section for information about connecting the
voltmeter, current shunt, and load.
