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 . In order to ensure best measurement environment please
must use the
M3 anti-interference screws
for installation .
HCM705B electronic compass with 1 meter cable, RION company optional cable can be 10
meters.The sensor cable as short as possible to get minimum noise. Although HCM705 to compensate
the moderate deviation in the stable magnetic environment, but it CAN NOT compensate the changeable
magnetic interference. Please special pay much more attention to the wire carry with a direct current to
create the magnetic field , because if the direct current change, size of the magnetic field will also change.
Battery is also another change of interference sources. Every installation is different and the user must
evaluate the installation feasibility of all possible operating conditions.
