How to calibrate magnetic field
You need to calibrate magnetic field after finishing the installation at the first time. If change
the working environment or the carrier of AHRS, the tract obvious deviates or the centre of the
tract circle is not in the centre of the window, when the AHRS rotates 360 degrees in the test, that
is to say, magnetic-field interference caused by environment, and that caused by calibrating with
change, you need to calibrate magnetic field again.
Open the calibration window:
Click the “VIEW” button on the menu, then choose the option “Magnetic Correction
Display”. (shown as below)
The tract obvious deviates when AHRS rotate a circle.
The procedure of calibrate magnetic field is as follow.
Attention to keep away from the magnetic object, for example, telephone, car engines,
electric motors, audio speakers, steel, iron and steel nuts or bolts and so on, AHRS
should be level placed and clockwise rotated a circle and a haft when calibration.
