Abstract

Method and apparatus for calibrating a temperature measuring device by operating a heat source at a preset temperature as determined by a temperature sensing resistor and a digitally calculated temperature which varies nonlinearly with the resistance of the resistor, and obtaining the coefficients for the calculation by operating the device at a preset temperature and comparing this temperature with that of a standard temperature measuring device.
