3. WHEEL SENSOR
This procedure is necessary when the navigation computer or wheel/tires have been
changed. The procedure calibrates the wheel circumference/speed sensor input to the
navigation computer so that the distance traveled input is correct.
The tire inflation pressure must be
checked and correctly set prior to
carrying out this test.
NOTE:
The screen instructions will
indicate a 4 and 6 meter distance in
this procedure. Field testing has
proven that a distance of 8 meters
provides a more precise wheel
sensor calibration.
1. Make sure the front wheels are
facing forward. Place the angle iron
against the back side of the rear tires.
2. Mark the road with the chalk where the angle iron contacts the road. This is your
starting point.
3. Using a metric tape measure, measure out 4 and 8 meters from the starting point
4. Mark the distance on the road surface at four (4) meters.
5. Mark the distance on the road surface at eight (8) meters.
