Claim:
1. A method of calibrating a header height controller, the header height controller comprising processing circuitry capable of receiving output signals from a plurality of height sensors mounted to a header, the output signals variable in magnitude with respect to changes in height of the header relative to a surface, the header height controller responsive to the output signals from the plurality of height sensors, the method comprising the steps of: moving the header through a range of motion relative to the surface; as the header moves through the range of motion, receiving and storing at predetermined sampling intervals the output signal magnitudes for each of the plurality of height sensors; defining a Set Point C Magnitude (“SPCM”) for each of the plurality of height sensors, wherein the SPCM is the magnitude of the output signal when the header is at an elevation in the range of motion where a last appreciable change occurs in the output signal magnitudes between one of the sampling intervals and a preceding one of the sampling intervals; defining a Set Point A Magnitude (“SPAM”) for each of the plurality of height sensors, wherein the SPAM is the magnitude of the output signal at a predetermined elevation in the range of motion above the elevation corresponding to the SPCM.
