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 12).
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.
CAUTION
The tests should be performed by qualified personnel. Hazardous
voltages may be present at the outputs of the power supply during
testing.
