Test Considerations
To ensure proper instrument operation, verify that you have selected the
correct power-line voltage prior to attempting any test procedure in this
chapter. page 24 for more information.
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.
• Keep cables as short as possible, consistent with the impedance
requirements.
Caution
The tests should be performed by qualified personnel. During performance
verification tests, hazardous voltages may be present at the outputs of the
power supply.
