Calibration

The factory calibrates the offset and range of the output voltage and current monitor circuits to within 1% for the default 0-10 Vdc scales. You may need to recalibrate when you select the 0-5 Vdc scale or when you switch back to the 0-10 Vdc scale after previously calibrating for 0-5 Vdc operation.

See Section 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.Set SW1 switch 5 OPEN to select 0-5 V output voltage monitor range, CLOSED for 0-10 V.

3.Connect a DVM across the power supply output to read the output voltage. Connect a second DVM between the rear panel J2 connector terminals 10 (output voltage monitor) and 9 (voltage monitor signal return).

4.Turn the power supply ON.

5.Set the power supply output voltage to 1% of the model-rated output.

6.Adjust the output voltage monitor offset (R397) until the monitor DVM reads 1% of the readback scale. (50 mVdc for 0-5 V readback or 100 mVdc for 0-10 Vdc readback.)

7.Set the power supply output voltage to the model-rated maximum.

8.Adjust the output voltage monitor range (R387) until the monitor DVM reads 100% of the readback scale. (5 Vdc for 0-5 V readback or 10 Vdc for 0-10 Vdc readback.)

Repeat this procedure until the monitor signal is adjusted to power supply specifications (see Section 1) or to the accuracy that your application requires.
