To performing a Full Calibration on the Inclinometers, follow the steps below:

Note: The angles for a full calibration on the inclinometers must be exact for the calibration to be valid. It is recommended to use a T-Square or other tools that have exact right angles. You should also always use the same surface on the inclinometer for reference; the feet and the back of the inclinometer are the recommended reference surfaces on the inclinometer.

1. Begin with the Secondary inclinometer disconnected from the Primary inclinometer
2. Select "Settings" from the main menu.
3. Use the Up or Down buttons until you highlight "Calibration." 
4. Press the Select Button to begin calibration.
5. Set the inclinometer in the upright position. 
6. Press the Select Button to save this position. 
7. Rotate the inclinometer 90 degrees to the left. 
8. Press the Select Button to save this position.
9. Rotate the inclinometer 90 degrees more to the left, so it is 180 degrees from the starting position.
10. Press the Select Button to save this position.
11. Rotate the inclinometer an additional 90 degrees to the left, so it is 270 degrees from the starting position.
12. Press the Select Button to save this position.
13. Place the back of inclinometer on a flat surface with the LCD face up.
14. Press the Select Button to save this position.
15. Place the front of the inclinometer on a flat surface with the LCD facing down.
16. Press the Enter Button to save this position.
17. Connect the Secondary inclinometer and repeat the process.
