3.8 Measurement Mode
Never try applying reflective tape to rotating objects if they are

Take all required safety precautions when applying reflective tape
to stationary rotating objects and when taking measurements.
If the rotating object to be measured does not have a highly reflective
surface, it is advisable to apply a reflective marker or multiple
reflective markers to the object.
Avoid exposing the sensor to light sources or applying the reflective
tape next to highly reflective surfaces, such as glass, as this can
affect measurement accuracy.
The ideal measurement distance to the object is between 10cm to
40cm. Refer to table 1 for the recommended tape size and measuring
distance.
