SEC380 Inclination compensation 3D electronic compass Electrical Interface Wiring definition BLUE BLACK GREEN YELLOW Wiring color function DC 9-36V （B、D-） （A、D+） Signal Electronic acquisition compass terminal RS485 Wiring diagram Electronic compass RS232 Wiring diagram Measurement installation The main sensitive devices of SEC380 sensor are magnetometer and accelerometer. The compass uses a magnetometer to sense the earth's magnetic field to calculate the sensor's pointing, uses an accelerometer to measure the angle between the compass and gravity, and provides inclination compensation when the compass calculates the azimuth angle. - Page 6 SEC380 Inclination compensation 3D electronic compass We strongly recommend to calibrate the magnetic field after the installation is complete and after each change in the magnetic field environment. After the calibration is completed according to the method in the manual, the firmware and program in SEC380 can effectively eliminate the interference of the magnetic field after calibration.
