Measuring axis and direction for Inclination
A single-axis inclinometer (vertical mount)
measures the inclination in the vertical plane over the full range
±180° (or 0-360°) (X-output). The default 0° position and the measuring direction are shown in Figure 9 - Measuring
axis and direction of 1-axis inclination.
Figure 9 - Measuring axis and direction of 1-axis inclination.
A dual-axis inclinometer (horizontal mount)
measures the inclination on both X and Y axis. The measuring range
is up to 90°. Due to the measurement principle, only one axis may tilt more than 45°.

Measuring axis and direction of 2-axis inclination.
Cross-tilt error: when the cross axis (axis perpendicular to the measuring axis) tilts more than 45° during the measurement,
the measuring axis will be disabled. The sensor will send a fixed CAN output to indicate that the sensor is now at a cross-tilt error
