The wheel magnet must be aligned so that it passes across the
sensor. As the magnet passes the sensor, it must be no further
from the sensor than 1 to 3mm (1/32 to 1/8 inch).
The wheel magnet has a ‘T’ shaped slot with two configura-
tions: round spokes and flat or bladed spokes (Figure 7).
1. Remove the screw from the magnet.
2. Slide the slot in the back of the magnet
over the spoke.
For a flat or bladed spoke, start the
spoke near the end where the spoke is
round, and align the top of the ‘T’ with
the spoke as you slide the magnet up the
blade (Figure 7).
3. Thread the screw into the magnet until it
is snug against the spoke.
