Chapter 3 SMART2 Operation
Zeroing the Terrain Compensation sensor while moving will negatively impact performance. Always
ensure the vehicle is stationary before zeroing the sensor.
Two-Stage zeroing must be completed outside with good GNSS visibility. A level surface is not
required.
To level the Terrain Compensation sensor, complete the following:
1. Park the vehicle where you can return to the same location but facing the opposite direction.
2. Ensure that you have good GNSS visibility.
3. Remain stationary for 15 seconds.
4. Begin the zeroing by issuing the following command:
TILTZERO NEW
5. Re-position the vehicle so that it is parked facing the opposite direction on the same spot, as close to 180
degrees as possible.
6. Remain stationary for 15 seconds.
7. Complete zeroing by issuing the following command:
TILTZERO ADD
For more information, refer to the TILTZERO command.
Single-Stage Zeroing
Single-stage zeroing can be used as an alternative to two-stage zeroing.
Zeroing the Terrain Compensation sensor while moving will negatively impact performance. Always
ensure the vehicle is stationary before zeroing the sensor.
A known level surface, such as a concrete floor of a shed or workshop, is required to perform the lev-
eling using the single-stage zeroing procedure. GNSS visibility is not required.
To level the Terrain Compensation sensor, complete the following:
1. Park the vehicle on a known level surface.
2. Remain stationary for 15 seconds.
3. Complete zeroing by issuing the following command:
TILTZERO ZERO
For more information, refer to the TILTZERO command.
Saving the Terrain Compensation Configuration
After the height has been set or the Terrain Compensation sensor has leveled, the Terrain Compensation con-
figuration must be saved. This is done so the height data and level setting are saved between power cycles. To
save Terrain Compensation configuration, enter the following command:
