12.2 Hysteresis error
12.3 Linearity error
The hysteresis error Δφ
given by the device output when performing a positive (clockwise) rotation and negative
(counter clockwise) rotation over an angular range of 180°, measured at a constant
temperature.
Equation 1
The KMA199 output signal deviation from a best straight line φ
the reference line, is defined as linearity error. The magnetic field angle is varied at fixed
temperatures for measurement of this linearity error. The output signal deviation from the
best straight line at the given temperature is the linearity error Δφ
magnetic field angle α and the temperature of the device T
