The heading accuracy depends on hardware and software. A fully calibrated sensor and ideal tilt
compensation are assumed.

Definition: gain error = ( (measured field after API compensation) / (applied field) ) – 1
4
Magnetic zero-B offset assuming calibration in fusion mode. Typical value after applying calibration
movements containing various device orientations (typical device usage).
