- Place the keyswitch in the BYPASS position.
- Secure the system. Verify that all the high voltage inputs to the system are open. Ensure that the flywheel is at zero rpm.
- Remove the lower sheet metal panel and the panel for the System I/O Interface Board. The panel for the System I/O Interface Board is located in the lower left corner of the cabinet.
- Connect a PC to the RS-232/RS-485 port ("J1"). The port is located on the bottom back corner of the system's I/O board. This must be accomplished prior to the application of high voltage to the system.

- Enter the value from Step 13 in the "Enter the value" field of the "Calibration of a Channel" window.
- Click on the "OK" button. When you depress the "OK" button, the window will automatically change to the "Voltage in Ph. B" field.
The "Calibration Group Status" window will display "Calibration complete but not saved" for phase A.
- Measure the input voltage from a "Phase B" terminal to neutral.
- Enter the value from Step 16 in the "Enter the value" field of the "Calibration of a Channel" window.
- Click on the "OK" button. When you depress the "OK" button, the window will automatically change to the "Voltage in Ph. C" field.
The "Calibration Group Status" window will display "Calibration complete but not saved" for phase B.
- Measure the input voltage from a "Phase C" terminal to neutral.
- Enter the value from Step 19 in the "Enter the value" field of the "Calibration of a Channel" window.
- Click on the "OK" button. When you depress the "OK" button, the window will display "Calibration Complete But Not Saved".
- Click on the "Save" button.
- When the message from illustration 8 is displayed, the procedure is complete.
