Claim 19:
20. A nip measuring device circuit configured to calibrate a nip measuring device, the nip measuring device circuit comprising:
a sensor multiplexer configured to receive signals from a sensor array that comprises a plurality of nip sensors that are configured to detect operational parameters of nip rollers;
a gain multiplexer configured to receive a plurality of gain resistances;
a plurality of sensor channel lines electrically connected between respective ones of the plurality of nip sensors and the sensor multiplexer;
a calibration resistor; and
a calibration channel line connected between the calibration resistor and the sensor multiplexer,
wherein a nip sensor resistance of a selected one of the plurality of nip sensors is determined based on a sampled signal on a respective one of the plurality of sensor channel lines associated with the selected one of the plurality of nip sensors and a respective one of the plurality of gain resistances selected by the gain multiplexer.
