Select "Op. Group 5: Model Index" from the "Op. Params." menu. Then, select "Load Cell Calibration Constant" from the "Model Index" submenu.
Select "Load Cell" on the "Calibrate" menu. The "Load Cell Calibration" dialog will open.
Select "View Status". A dialog box will open that provides a text message. The message indicates the status of the process (calibration). Initially, the dialog will show that the minimum has not been calibrated.
Select "Use Defaults".

Click the "OK" button on the calibration dialog. The dialog (status) will indicate that the calibration values have not been saved.
Click the "Save" button on the calibration dialog.Note: At the end of Step 37, two errors (temperature) will be announced on the dialog. The errors will be cleared when the wiring harness is reconnected in Step 38.
Connect the wiring harness to the flywheel interface board.Calibration is complete.Calibration Check
A proper calibration can be verified by using voltage measurements and a calculator.
Measure the voltage between pins "16" and "4" on the flywheel interface board and record the voltage. The value will be "Ve".
Measure the voltage between pins "11" and "12" on the flywheel interface board and record the voltage. The value will be "VL". The voltage measurements are completed only with control power on.

Calculate the force (bottom bearing) that is expected by using the equation in Illustration 19.
Compare the value that is calculated with the reading that is indicated by UPSView. The values should agree within 1 percent.
