Step Action for Voltage Calibration
1. 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.
2. Wait at least 5 seconds and press the ESCAPE key.
3. 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.
4. 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.
