Important notes
Calibration setup
➜ Before starting the calibration procedure, make sure to set up the total station at a location from which you can measure all necessary points. Fully extend the blade wings. 
➜ It is recommended to use the Leica CPR111 TrueZero prism (761712) for the calibration process.
Setting the cutting angle of the blade
- Fully extend the blade wings and level the blade.
- To set the cutting angle, pitch the blade until the main blade and the blade wings are all at the same height and parallel to the ground.
➜ Make sure that the blade is set to the correct cutting angle, as this angle has a significant influence on the quality of the calibration results.
Measuring the GNSS positions
GNSS positions must be measured correctly. Before measuring the GNSS positions, make sure that you have entered the correct prism height. Take into account the height of the thread.
Machine calibration for snow groomers step-by-step
➜ Make sure the snow groomer is correctly set up for calibration. Refer to section Important notes (page 523).
- Open the MC Calibration app.
- Select Snow Groomer.
-
• Define the measuring side.
• If you want to calibrate the snow groomer including the winch, set Measure winch to On.
To accept, tap

The calibration screen is displayed. Refer to section The calibration
screen(page 515).
➜ Always adhere to the instructions in the display. - Enter pitch angle and roll angle. To start calibration, tap
. 
- Aim telescope to target point. Measure and store the target point using the measure bar buttons.
➜ To remeasure points, tap the relevant point in the map screen and confirm the warning message. - Tap bto proceed to the next calibration step. Follow the instructions on the screen.
Aim telescope to target point. Measure and store the target point using the measure bar buttons.
➜ Repeat until all points have been measured successfully. You can go back to a previous step to remeasure points or to measure missing optional points. Select Back from the toolbox. - When all points have been measured successfully, the Machine calibration results screen is displayed. To accept, tap
. - Before saving the calibration results, you can set the file location and change the default file name. To store the results onto a connected USB stick, tap Save to and choose USB.
• To save the results, tap
.
• To cancel the saving process and remeasure points, tap
. After successfully measuring points again, execute a recalculation using Calculate from the Toolbox. The new results are displayed.
➜ To display the calibration results again, open the MC Calibration app and tap Calibration Results.
