3 Sensitivity

The sensitivity dial does not change the signal in any way. It is simply an interface to allow the operator
to adjust the threshold at which the switch will be closed and the velocity will be calculated. By default,
the switch is set to 4, which is the middle of the range. The higher the number, the more sensitivity or
lower the threshold. When set to 0, the Sasquatch enters the program mode, does not take magnetic
readings, and does not operate the switch.

3.1 Default Sensitivity

The magnetic sensor has an incredible amount of sensitivity, more than is needed for sensing any
material type. To prevent false detections the maximum sensitivity has been limited by default. Setting
7 has a default detection threshold of 25 counts, even though it could go as low as 1. As the sensitivity is
turned down, the sensor looks for twice the amount of change in the signal.
The table below highlights the relationship between sensitivity setting and detection threshold:
