The TE-74 is preloaded with default coefficients to use with the Steinhart-Hart equation to convert the measured resistance to temperature. For optimal performance these values should be updated with the values that are typically provided with calibrated temperature probes. A, B and C values for each channel can be individually commanded to adjust the TE-74 input to the sensor connected to the input.
