2.3.2 Magnetic Field Calibration
Purpose:
Magnetic calibration is used to remove the zero bias of the magnetic field
sensor. Usually, the magnetic field sensor will have a large zero error when it is
manufactured. If it is not calibrated, it will bring a large measurement error,
which will affect the accuracy of the measurement of the z-axis angle of the
heading angle.
Preparation:
1. Sensors should be 20cm away from magnetic and iron and other materials
2. The value of H in magnetic field must be lower than 350.
Methods:
Step 1. Open the Config menu.
Step 2. Click the “magnetic field” and slowly rotate the sensor 360° around X,
Y, Z, 3-axis accordingly.
