2.3
A third output of the measuring system - typically called reference, index point or zero point signal -
considered to be activated, if the difference of the signals at the REFP and REFN pins becomes greater than
the positive hysteresis voltage V
the negative hysteresis voltage V

If a sensor without reference signals is used, defined levels on pins REFP and REFN are necessary to
setting the index point always active or always inactive, respectively.
