Test Considerations
To ensure proper power supply operation, 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:
• Assure that the calibration ambient temperature is stable
and between 20 °C and 30 °C.
• Assure 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.
