Measurement of Acceleration, Inclination Angles or Angular Velocity
The sensor is located at the red rectangle position. Press keypad "9" to measure the variation of 3D acceleration in g (moving), inclination angles in degree (stationary) or angular velocity within 10s.

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. Furthermore, the logger will record the angular velocity in unit of Deg/s or degrees per second (dps) around the X, Y and Z axes.

Press "D" and then "*" in the keypad to select one of the following combinations of physical quantities to record:

1. Acceleration in 3D
2. Inclination Angles
3. Angular Velocity in 3D
4. Acceleration and Angular Velocity
5. Inclination Angles and Angular Velocity
