Trigger-Level (as per set-up) Trigger-Level (as per set-up)
Acceleration sensor
In case of acceleration sensor, there is an additional selection: the trigger mode. The choice is
between Level and the STA/LTA.
In both cases, before applying the trigger mode, a band-pass trigger filter between 0.5 and 15 Hz
is applied on the signal. This means that en event is created only if both the conditions are fulfilled:
the trigger condition is exceeded;
•
the peak is associated to a frequency in the range 0.5 – 15 Hz.
•
In case of Level, the acceleration threshold for the trigger activation can be chosen on each of the
three axes.

Due to the presence of the trigger filter, values exceeding the trigger threshold do
not necessarily lead to an event creation.
