Measurement of Accleration or Inclination Angles
3D accel. in g (moving) and angles in deg (stationary).

Remarks:
When the mobile logger is accelerating or decelerating, it will record the acceleration a_x, a_y and a_z along its three (X, Y and Z) axes in unit of g (acceleration due to gravity). When it is non-accelerating or stationary, it will record the inclination angles between the Earth's normal and its three axes. The X and Y axes are shown in the above diagram while the Z axis is pointing vertically upwards from the surface of the logger.
