Calibration
Figure 16 Typical angle error with initial calibration at 25°C/50mT and subsequent measurements
considering 10% magnetic field change due to aging and air gap variation (i.e. 45mT @25°C).
Magnetic field values change with a TC of -2000ppm/K (ferrite magnet material). Magnetic
field values are indicated at each measurement temperature.
