Claim 4:
5. A compensation circuit according to claim 4, wherein the resistances of the voltage divider circuitry are adjustable such that a calibration ratio comprising:
a difference between a ratio of the combined values of the second and third resistances to the combined values of the first, second and third resistances and a ratio of the value of the third resistance to the combined values of the first, second and third resistances
is equal to:
a sensor ratio comprising:
a difference between a ratio of the value of a first resistance of the force sensor to the value of a second resistance of the force sensor and a ratio of the value of a third resistance of the force sensor to the value of a fourth resistance of the force sensor.
