Operating Manual for XFR 1.2kW Series Power Supply

Calibrating for Programming Accuracy

The factory calibrates the offset and range of the voltage and current programming
circuits to within 1% for the default 0-10 Vdc programming signals. You may need
to recalibrate when you use 0-5 Vdc programming or when you switch back to
0-10 Vdc programming after previously calibrating for 0-5 Vdc programming.

See “Calibration Setup” on page 79 for the procedures to remove the cover and any
option card. Follow all procedure steps in the sequence given.

Voltage

Programming

Circuit

Calibration

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 model-rated output voltage.

7. Apply 100% of program voltage.
8. Adjust the voltage program range potentiometer (R462) until the DVM reads the

model-rated output voltage.

Repeat this procedure until output levels are adjusted to specifications (see
Section 1. Features and Specifications) or to the accuracy that your application
requires.
