In the terrain trimmer settings menu is Trim trim. The procedure is necessary for the system to GeoNave identify all parameters related to the physical installation of the compensator on the tractor, making the reading of the steering, inclination and pitch angles to be carried out in the most accurate and correct way possible.
Selecting the item in the menu and pressing the confirm button 
, the screen for the start of steps 1 and 2 of the calibration will be presented, in which the procedures are carried out with the tractor in the direction of going, as shown in the following figure.
The screen informs the user of a list of three necessary items before starting the calibration, so that the machine must be stopped on a level ground, with the engine turned off, and the user must draw aligned “T” marks on the floor. with the axle of each of the tractor’s 4 wheels.
Pressing the confirm button , Step 1 of the calibration will begin, in which the electronic components are calibrated for approximately 1 minute. Right afterwards, step 2 will be carried out automatically, where the inclination of the machine / compensator set in the direction of going is calculated. The images below show the Loading referring to steps 1 and 2 of the calibration.
After the completion of step 2, the screen at the beginning of step 3 will be displayed, as in the figure below. The user is asked to make the turn with the machine, returning to the same alignment as the previous point of the trip, but in the opposite direction of the turn, making the 4 wheels again align with the marks present on the floor. Once again, the machine must be turned off, and press the confirm button .
At the end of step 3, the Information indicating the success of the calibration operation, as in the image below.
If, during any of the three stages, there is any movement of the tractor or the terrain compensator cabinet, the calibration process will detect the improper movement, and the process will end with an error, as shown in the following figure.
