Sensor Over Range only applies to the rotational rate sensors; over‐range is not
ered for accelerometer readings. In many applications, vibration causes
ntaneous acceleration levels to exceed the accelerometer sensor range.

hardwareBIT Field
The hardwareBIT field contains flags that indicate various internal hardware errors. Each hardware error has an
associated message with low level error signals. The hardwareError flag in the BITstatus field is the bit‐wise OR of
the hardwareBIT field.

hardwarePowerBIT Field
The hardwarePowerBIT field contains flags that indicate low level power system errors. The powerError flag in the
hardwareBIT field is the bit‐wise OR of the hardwarePowerBIT field.
