Transfer Functions
The examples in Figure 3 show how different magnetic field ranges can be mapped to
the desired output value ranges.
• Polarity mode:
– Bipolar: Magnetic fields can be measured in both orientations. The limit points
do not necessarily have to be symmetrical around the zero field point
– Unipolar: Only North- or South-oriented magnetic fields are measured
• Inversion: The gain values can be set positive or negative.
