Step

Action for Voltage Calibration

Using the Meter Calibration Menus, reset the plant voltage reading by selecting RESET VOLTAGE. Press

the Enter key to reset the voltage.

This will remove any pre

existing user calibrated values if they exist.

Wait at least 5 seconds and press the ESCAPE key.

Select CALIBRATE VOLTAGE. Use the Arrows, and UP/DOWN keys to

calibrate the system voltage. Press ENTER to save.

NOTE:

The controller will not allow changes greater than +/

0.5V of the

displayed voltage.

Press the <ESCAPE> key until the default screen is displayed. Verify

that the plant voltage reading now agrees with the calibrated DVM.

NOTE:

The DVM reading will be the one to change since Rectifier Manager will adjust rectifier outputs as
necessary per the calibration performed.

Step

Action for Current Calibration

NOTE:

The following procedure is applicable only in plants with Load shunts
