CALIBRATION
To calibrate the Wheel Speed sensor, follow these steps:
1.
Measure out a set distance on the ground for calibration (greater than 20m). Peg both start and
end points.
2.
Align magnet and sensor by moving forward.
3.
Mark a point on the tire that corresponds with the start point.
4.
Make sure the Method dropdown list has Calculated selected.
5.
Select the Enter Distance button and enter the distance (from step 1) the wheel will travel during
the calibration.
6.
Select the Play button.
7.
Drive along the measured distance slowly (from step 1).
8.
Stop at the pegged point, lining up the bottom of the tire with the end peg point.
9.
Select the Stop button.
10.
Select the Calculate button (the calculator symbol).
11.
Select the green Tick.
Alternatively, you can change the Method to MPP (Meters per pulse) and enter a known factor. To do this:
1.
Align magnet and sensor by moving forward.
2.
Mark a point at the bottom of the tyre and on the ground (normally bottom centre).
3.
Drive one full rotation of the wheel and stop when marked point on tyre is centre bottom.
4.
Measure between the two points.
5.
Insert the measurement on the m/Pulse button.
