4.6
If the sensor is accelerated into the indicated directions, the corresponding channels will deliver
a positive acceleration signal (dynamic acceleration).
Example: If the sensor is at rest or at uniform motion in a gravity field according to the figure
given below, the output signals are:
The following table lists all corresponding output signals on Ax, Ay, and Az while the sensor is
at rest or at uniform motion in a gravity field under assumption of a top down gravity vector as
shown above.
