Calibration
The factory calibrates the offset and range of the voltage and current programming circuits to within 1% for the default
See “Calibration Setup” on page 79 for instructions to remove the cover and any option card. Follow all procedure steps in the sequence given.
1.Ensure that the power supply is turned OFF. Disconnect any load.
2.Connect the program source between J2 connector terminals 6 (output voltage program input) and 5 voltage program signal return).
3.Connect the DVM across the power supply output.
4.Turn the power supply ON.
5.Apply 1% of program voltage.
6.Adjust the voltage program offset potentiometer (R472) until the DVM reads 1% of the
7.Apply 100% of program voltage.
8.Adjust the voltage program range potentiometer (R462) until the DVM reads the
Repeat this procedure until output levels are adjusted to power supply specifications (see Section 1) or to the accuracy that your application requires.
