6.5 Vehicle mass calibration
The mass calibration of the vehicle requires the vehicle profile data to be already configured.
The calibration of mass is performed by driving the vehicle at two load levels, where the difference
between the two loads should be 40% of the maximum payload. The first point can be calibrated
when the vehicle is empty, or at 0% of maximum payload. Follow the steps indicated below and
set the new mass value to 0%.
Once the new mass is set to zero percent, drive the vehicle over speed breakers a few times to let
the AutoMonitor learn the behaviour of suspension system. Set the second calibration point of
vehicle mass by adding load into the vehicle. The load added should be over 40% of maximum
payload. Once the mass is added and the vehicle is ready to be driven, set the new mass value to
the amount of payload just added into the vehicle. Perform another test drive over speed breakers
a few times. Once the mass has been calibrated, the real-time mass of the vehicle will be
displayed on the screen.
Note:
While the mass calibration is being performed and AutoMonitor learns the vehicle’s profile,
the LCD will display ‘c’ to indicate mass-calibration mode. While the AutoMonitor is in mass-
calibration mode, the vehicle mass value might not update and the rollover alarms might not be
accurate until the mass profile has been learnt by the system.
