Introduction
SHOCK HAZARD, LETHAL VOLTAGES - Some models generate output voltages up to
2,000 VDC! Ensure that all instrument connections, load wiring, load and sense
connections are insulated using high-voltage wire. Always attach the safety cover
provided, so that no accidental contact with lethal voltages can occur.
Use the performance verification tests to verify that the unit under test (UUT) is operating normally and
meets its published specifications. You can perform two different levels of performance verification
tests:
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 re-
calibrated.
