▶ INTRODUCTION DCM301B/DCM302B is a 3D electronic compass with high precision using two-dimensional plane calibration algorithm. The calibration does not require a three-dimensional attitude tilt, and only needs to rotate the plane in place to complete the calibration process. Using hard magnetic and soft magnetic calibration algorithms, the compass can achieve ideal measurement results through three-dimensional calibration in an environment with magnetic interference. This compass integrates three-axis magnetic sensing technology, which can calculate the heading in real time through the...

MEASURING DIRECTION AND INSTALLATION Since the azimuth angle of the DCM302B three-dimensional electronic compass is based on the principle of geomagnetism, it is important to choose an environmental installation location with minimal magnetic interference. Please install DCM302B as far away as possible from iron, magnets, motors, and other magnetic objects. Even if there are these magnetic media around, at least the distance needs to be controlled above 40CM (different magnetic fields interfere with the compass at different distances). To ensure that the product reaches the best measurement...

Calibration prerequisite: 1) The accuracy of the test compass fails to meet the requirements; 2) There is magnetic interference in the compass installation environment. This interference is fixed, and the distance between the interference magnetic field and the compass will not change after installation (for example: the compass is installed on an iron material, because iron will interfere with the magnetic field. It is necessary to rotate and calibrate the iron and the compass together, and the iron will not be separated from the compass during use. Once it is separated, it needs to be...

DCM301B / DCM302B 3D DIGITAL COMPASS Refer to the figure below for the calibration method Note: If the compass is fixedly installed in other ancillary equipment, and the device has magnetic interference, please install the compass, and rotate it with the ancillary equipment to collect the interference source of the ancillary products to ensure that the compass can accurately measure. When the user is calibrating, if the distance between the magnetic interference source and the compass itself changes, the calibration effect will be very low, and the accuracy will be very poor.
