Each instrument has been factory calibrated to ensure accuracy. It is possible that the user calibration may be different from these pre-set parameters, which may lead to invalid force/angle reading. Prior to performing a full calibration, attempt to restore the factory calibration stored on each instrument. If this does not correct the problem a full calibration may be required.

Follow these steps to restore the factory calibration:
1 . Select “Settings” from the main menu.
2 . Use the Up or Down buttons until you highlight “Restore.”
3 . Press the Select Button to select restore.
4 . The LCD screen will display “RESTORE CALIBRATION.”
     i . Select, “No” to return to the Settings menu.
    ii . Select “Yes” to restore the factory calibration settings.
Note: Restoring the factory calibration only overwrites the user calibration data with the factory calibration data stored on the instrument.
Note: For information on recommended annual factory recalibration, contact JTECH Customer Service at (800) 985-8324, ext. 4 or This email address is being protected from spambots. You need JavaScript enabled to view it.
