Remote temperature sensors are typically calibrated for transistors with an η-factor of 1.008, but transistors may have η-factors that differ from this. If the value is known, an η-factor correction register can be used to correct the error resulting from a deviation of the calibrated η-factor. A combination of offset and η-factor correction settings can correct for both η-factor errors and other system errors that are present. The Remote Temperature Sensor Calibration Tool can calculate the optimal offset and η-factor correction settings for a given data set, and these register settings can be used with devices such as the TMP468, which includes an independent register for each remote input.
