1. A method for verifying measurements obtained from a hall effect sensor in a hall effect sensor system, the method comprising:

  • exciting the hall effect sensor with an excitation current having a first value;

    obtaining a first measurement corresponding to a voltage output of the hall effect sensor when the hall effect sensor is excited with the excitation current having the first value;

    exciting the hall effect sensor with the excitation current having a second value, the second value different than the first value;

    obtaining a second measurement corresponding to a voltage output of the hall effect sensor when the hall effect sensor is excited with the excitation current having the second value;

    verifying operation of the hall effect sensor based at least on the first measurement and the second measurement.
