Sensitivity
A sensitivity value specifies how much the signal must change to detect a peak or valley. It can be used
to keep the activity from seeing signal noise as a new peak or valley:
• Setting the sensitivity too low may cause signal noise to be recognized as peaks and valleys.
• Setting the sensitivity too high may cause low amplitude signals to be missed.

Tolerance
The tolerance band specifies how much a peak or valley must deviate from the associated reference levels
before it generates a trigger signal.
For example, if the established peak value is +5 cm, and the tolerance is set to ±0.25 cm, the activity does
not generate a trigger signal unless the peak value registers greater than +5.25 cm or less than +4.75 cm.
