Figure 9- Magnet alignment and clearance
1.0 - 3.0mm
Attaching the sensor
The magnet must pass across the line on the sensor (Figure 9).
To install the sensor
1.Align the sensor with the magnet.
2.Orient the sensor so that the clearance between the sensor and the magnet is between 1 to 3mm.
The sensor can be rotated around the fork about 45 degrees.
If needed, the sensor and magnet can be moved up or down the spoke and fork to change the amount of clearance.
3.Attach the sensor with nylon ties, but do not fully tighten.
4. With the computer in the computer base, check the alignment of the sensor and magnet by spinning the wheel and noting if the computer is displaying speed.
If the computer shows current speed, the sensor is reading the magnet. If the computer is not displaying a value, realign the sensor and magnet until one is displayed.
