User Manual
5.2
Angular Rate and Acceleration Limits
The 3DM-GX5-10 angular rate and acceleration ranges depend on the sensors installed in the device.
Exceeding the specified range for either sensor will result in sensor saturation and errors in delta theta
and delta velocity outputs.
5.3
Communications Bandwidth
When selecting sensor outputs to be recorded, communication bandwidth considerations should be
taken into account, especially when using RS232 serial communications. Lower baud rates equate to
lower communication bandwidth, which can be consumed quickly by selecting a large number of
measurements at high sample rates. Overrunning the communication bandwidth will result in dropped
data packets. Most computer RS232 ports are limited to 115,200 baud even though the 3DM-GX5-10
is capable of running at 921,600 baud.
5.4
IMU Sensor Calibration
All of the internal sensors in the 3DM-GX5-10 are calibrated when the device is manufactured, and the
calibration values are saved in the device memory. Recalibration is not required unless the device has
been under conditions that exceed the operating specifications. For example, if the sensor has been
exposed to excessive shock beyond the rated g-force, performance may be compromised. Indications
of internal sensor damage may be seen as excessive measurement offsets or drift when the sensor is
in a neutral motionless position.
5.5
Temperature Compensation
All sensor conversion and calibration formulas include temperature compensation. All computed
outputs and IMU sensor outputs are automatically adjusted for local temperature.
