- Page 7 HCM370B&375B-MP HIGH ACCURACY 3D DIGITAL COMPASS heading accuracy measurement (of course the rotating rod perpendicular to the rotating platform, as much as possible to avoid large external magnetic field interference). Doing so can reduce the compass turning radius, to scientifically improve the measurement accuracy. This is just to provide the installation of the laboratory, must be flexible to deal with the specific situation.E.g: is mounted in the car,...

Page 8: Calibration Description
HCM370B&375B-MP HIGH ACCURACY 3D DIGITAL COMPASS ▶ CALIBRATION DESCRIPTION Calibration lemmas: 1) The accuracy of testing compass cannot reach the requirements. 2) compass installation environment has magnetic interference, the interference is fixed, and the interference magnetic field and compass installation will not happen again in distance changes... - Page 9 HCM370B&375B-MP HIGH ACCURACY 3D DIGITAL COMPASS The calibration steps are as follows: The starting point of the calibration can be in any point in 360°, as long as it keeps about 90° for every change of angle (accuracy is not required).
- Page 10 HCM370B&375B-MP HIGH ACCURACY 3D DIGITAL COMPASS P calibration is completed after the 16th point is collected, and then R, R (roll value) can be calibrated alternately. Refer to Pic.E: Starting point H=0°, R=+15°, P=0° Please keep this attitude for 2 to 3 seconds, the system will take the 17th point.
