The cursor moves to the air count setting to begin normalizing the

Normalizing the sensor
The sensor is normalized using a special normalization tube to set the air
and water counts. This is necessary because each sensor responds slightly
differently to air and water. By entering these counts into the equation as
described in Appendix A, it is possible to standardize all sensor readings,
i.e. readings taken by different sensors become comparable.
This results in meaningful data and flexibility in the use of probes.
