HCM375B 3D electronic compass azimuth is using geomagnetic principle, so it is very important to select
a minimum magnetic interference environment for installation positon. Please place and install the it
away from the iron, magnets, engines and other magnetic objects as much possible as you can. Need
control over 30CM distance(different magnetic interfere with the compass in different distance ) at least
even there are these magnetic medium around . In order to ensure optimal measurement environment
please must use the M3 anti-interference screws for installation .
Although it can compensate the moderate deviation in the stable magnetic environment, but it can not
compensate the changed magnetic interference. Please pay much attention to the wire with DC will
generates a magnetic field , because if the DC change then the magnetic field will also change in size .
The battery also is another interference source of changing . Each installation is different, and the user
must evaluate the feasibility of installation under all possible operating environment.
The optimal heading accuracy of it 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
electronic compass to a vertical and erect aluminum pole (non-magnetic material), then proceed with
