6.1.2 Gyroscope
The gyroscope used in the rollover sensor is a tri-axial digital gyroscope and requires calibration
for all three axes at two temperature points. The first temperature can be the room temperature,
while the second temperature can be at about 0
C.
To calibrate the first point at room temperature, leave the rollover sensor connected in a room for
10 minutes. Place the gyroscope on a plane surface and click on start to start the first point
calibration. The rollover sensor should not move during the first 15 seconds. After 15 seconds click
on stop.
Figure 46: Rollover sensor calibration - gyroscope
To calibrate the second point of the gyroscope, raise the temperature of the rollover sensor to 40
C or lower the temperature to about 0
C. Once the expected temperature is reached, connect
the rollover sensor to the vehicle unit and the follow the same steps described earlier for the first
temperature point.
