Installation

• Though SkyMEMS E-Compass can compensate magnetic interference, please install and use the compass in the environment that has no or very little magnetic interference. And please keep the compass far away from iron, nickel, magnetic-iron, motors and other types of magnetic materials.

• Be sure that keeping strong magnetic materials (such as magnetic iron and motors) away from the compass, which will damage the compass’ accuracy, and the damage can’t be recovered.
  SkyMEMS E-Compass has done calibration in the factory, if using it in the environment where there is no or less magnetic interference, it can be used without the environment calibration. It is better to do the magnetic calibration in the actual application. The calibration procedure please refers to “User Manual of SkyMEMS E-Compass Second Calibration Software”.

• Remarks: during the calibration, the operator should not have mobile phone, keys, and other material that can generate the magnetic field.

Communication Protocol

• You may get direct access to the product through communication protocol (RS232), with which the product can be easily integrated into your system
