8.2 Sensing axes orientation
If the sensor is accelerated in the indicated directions, the corresponding channel will deliver a
positive acceleration signal (dynamic acceleration). If the sensor is at rest and the force of
gravity is acting along the indicated directions, the output of the corresponding channel will be
negative (static 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 X, Y, and Z while the sensor is at
rest or at uniform motion in a gravity field under assumption of a ±2g range setting and a top
down gravity vector as shown above.
