Dynamic Sensing • Precision Measurement and Control Measurement Direction and Installation Requirements The 3D electronic compass measures azimuth based on geomagnetic principles; therefore, it should be installed in an environment with minimal magnetic interference. To ensure measurement accuracy, please adhere to the following installation guidelines: 1. Magnetic Interference Mitigation: ♦ Keep the device away from iron, magnets, engines, and other magnetic objects. ♦ Maintain a distance of at least 30 cm from known sources of magnetic interference (the required distance may vary depending...

Dynamic Sensing • Precision Measurement and Control NORTH HEADING Calibration prerequisites: 1) The compass accuracy fails to meet the required specifications; 2) If the installation environment contains a constant magnetic interference source (e.g., the compass is mounted on a ferrous material), the interference source must be rotated synchronously with the compass during calibration. Furthermore, their relative positions must remain fixed during operation; otherwise, recalibration will be necessary. If the interference source is variable in terms of size or distance (e.g., movable iron objects),...

Dynamic Sensing · Precision Measurement and Control may repeat the calibration steps above or revert to the factory-default calibration data. 6）Send the calibration start command (as described in step 2) to begin the process. Keep the module's orientation stable and wait for the first data point to be sampled. 7）After the first point is sampled, rotate the module approximately 90 degrees horizontally, hold it steady, and wait for the next data point to be sampled. (Refer to the calibration steps in the diagram below.) 8) Repeat these steps until 24 data points have been collected, then send the...

Dynamic Sensing · Precision Measurement and Control The system will capture the 7th point. After capturing the 7th point, rotate the device 90° horizontally and hold this position steady for 2–3 seconds; the system will then capture the 8th point. Once the 8th point is captured, keep the H and R values unchanged, and proceed to calibrate the P (pitch) angle. Refer to Pic. C: Starting at H=0°, R=0°, and P=-15°, hold this position steady for 2–3 seconds; the system will capture the 9th point. After capturing the 9th point, rotate the device 90° horizontally and hold this position steady for 2–3...

Dynamic Sensing · Precision Measurement and Control point. After capturing the 22nd point, rotate the device another 90° horizontally, adjust the roll (R) to +55°, and hold this orientation steady for 2–3 seconds; the system will capture the 23rd data point. After capturing the 23rd point, rotate the device another 90° horizontally, adjust the roll (R) to -55°, and hold this orientation steady for 2–3 seconds; the system will capture the 24th data point. Send the "stop" command—the compass will respond—then send the "save" command; the compass will confirm that the data has been saved successfully!...
