Abstract: An apparatus for use with a digital field sensor comprises a digital communication circuit. The digital communication circuit is operative to output a digital signal indicative of calibration information for the digital field sensor. A processor is connected in operational communication to the digital communication circuit. The processor is operative to receive a value communicated to the processor by the digital field sensor. The processor is also operative to calculate calibration information based on the value and to provide the calibration information to the digital communication circuit.
