Calibration concepts
The following figures illustrate various FlexPI calibration functions. Figure 29: illustrates the Cut
Alarm Settings. The Window is set at 30 seconds, the Threshold is set at 10, the Count is set at 4
and the Cut Profile is set to 20%. The first part of the figure shows how 4 impacts within 30
seconds triggers a Cut Alarm (without the Cut Profile parameter). In the second part of the
example the Cut Profile is set to 20%, thereby, extending the Window by 6 seconds for each
recorded Count. Note that without the extra time created by the 20% Cut Profile, the second attack
would not cause an alarm.
Figure 30: illustrates the Climb Alarm concept of a sustained attack within a specified time.
