Test Considerations
To ensure proper operation of the power supply, verify that you have selected the
correct power-line voltage prior to attempting any test procedure in this chapter
(refer to “Converting line voltage” on page 36).
Ensure that all terminal connections (both front panel and rear panel) are removed
while the internal self-test is being performed.
For optimum performance verification, all test procedures should comply with the
following recommendations:
– The calibration ambient temperature is stable and between 20 °C and 30 °C.
– The ambient relative humidity is less than 80%.
– Allow a 1-hour warm-up period before verification or calibration.
– Use short cables to connect test setups.
The tests should be performed by qualified personnel. Hazardous voltages
may be present at the outputs of the power supply during testing.
