Page 4: Mechanical Characteristic
SEC385M Inclination compensation 3D electronic compass MODBUS Resolution: The measured minimum change value that the sensor can detect and resolve within the measurement range. Accuracy: The error between the actual angle and the Root mean square(RMS) of the measured angle of the sensor (≥16 times). - Page 5 SEC385M can effectively eliminate the interference of the magnetic field. As long as the position of the compass and the surrounding magnetic field environment have not changed, it is no longer necessary to compensate the sensor.
