Negative HCM705B Measuring Directions&Fix The azimuth of HCM705B 3D electronic compass is using geomagnetic principle, so it is very important to select a minimum magnetic interference environment for installation . Please install the HCM505B away from the iron, magnets, engines and other magnetic objects as much possible as you can. Need control over 30CM distance(different magnetic interfere the compass in different distance ) at least even there are these magnetic medium around . - Page 5 HCM705B High Accuracy Gyro Compass The best heading accuracy of HCM705B can reach 0.3° ～ 0.5°, this undergo a rigorous validation indisputable, the most scientific test method is equally crucial. The test method we recommend is: Please install the HCM705B electronic compass to a vertical and erect aluminum pole (non-magnetic material), then proceed with heading accuracy measurement (of course the rotating rod perpendicular to the rotating platform, as much as possible to avoid large external magnetic field interference).

Note: When you start the calibration and take points, move the compass to the following location, please note that these points are not absolute heading orientation, but with reference to the first point sampling heading orientation relative orientation change value.
