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. See page 21 for line voltage conversion.
Ensure that all connections of terminals (both front panel and rear panel) are
removed while the power supply 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 set-ups.
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.
Operation Verification and Performance Tests
Operation Verification Tests
To assure that the power supply is operating properly, without testing all
specified parameters, perform the following test procedures:
•Perform the power-on self-test and check out procedures on page 18.
(See “Self-Test” on page 56 for more information)
• Perform the Voltage Programming and Readback Accuracy test, and the
Current Programming and Readback Accuracy tests in this document.
Performance Tests
The following sections provide test procedures for verifying the supply’s
compliance with the specifications listed in Table 8-1, “Performance
Specifications,” on page 149. All of the performance test specifications and
calculated measurement uncertainties are entered in the appropriate
Performance Test Record Card for your specific model. You can record the
actual measured values in the column provided in this card.
If you use equipment other than that recommended in Table A-1, you must
recalculate the measurement uncertainties for the actual equipment used.
