To install the sensor
These instructions are written for the
cadence sensor, which goes on the frame’s
left chainstay. The instructions apply
equally to installing the ACH Digital
cadence sensor or the wheel sensor on the
fork- where there is no wire on the sensor.
1. Align the sensor with the magnet.
1. Align the sensor with the magnet.
The magnet must pass across the line on the
sensor (Figure 9).
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 crank
about 45 degrees.
If needed, the sensor and magnet can be moved
up or down the crank and bike frame to change
the amount of clearance.
3. For a wireless sensor, install the rubber
“foot” in the sensor (Figure 10).
The ACH Digital has an integrated rubber foot.
4. Attach the sensor with nylon ties, but
do not fully tighten.
