The activity measurement configuration is accessible after a click on the arrow > is done. It is then possible
to:
-Enable/disable the activity algorithm (TAT based algorithm)
-Adjust the algorithm computing period in min or s (from 30s to 30min). The TAT value recorded
for each period corresponds to the number of times the selected acceleration threshold was
reached or exceeded. Thus, for a configuration of 25Hz associated with a period of 1 minute, the
recorded TAT values will be between 0 (no activity) and 1500 (system saturation corresponding to
a maximum activity: 25Hz * 60s)
-Adjust the acceleration threshold to compute the activity level (a 0.1G threshold correspond to
an acceleration value of 1.1G).
