DCM250B/DCM260B HIGH ACCURACY 3D COMPASS ▶ INTRODUCTION DCM250B/260B is a low-cost three-dimensional electronic compass, using hard and soft magnetic calibration algorithm, so that the compass can eliminate the influence of magnetic field through the calibration algorithm in the environment with magnetic field interference. The DCM250B&260B integrates a three-axis fluxgate sensor, calculates the heading in real time through the central processor, and uses a three-axis accelerometer to perform heading compensation for a wide range of tilt angles, ensuring that the compass can also provide high...

DCM250B/DCM260B HIGH ACCURACY 3D COMPASS Because the azimuth of the DCM250B&260B three-dimensional electronic compass uses the principle of geomagnetism, it is necessary to choose the environment installation location with the smallest magnetic interference. Please install the product away from iron, magnets, motors and other magnetic objects. Even if there are these magnetic sources around, it needs to be kept away at least 40CM (different magnetic fields have different interference distance). In order to ensure product measurement accuracy, M3 anti-interference copper screws must be used during...

DCM250B/DCM260B HIGH ACCURACY 3D COMPASS Prerequisites : 1) The accuracy of the test compass does not meet the requirements; 2) There is magnetic field 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 have magnetic field interference, which It is necessary to rotate and calibrate the iron together with the compass, and the iron will not be separated from the compass during use...
