This paper describes calibration principle of the thermal resistance based thermometer, and put forward digital thermometer calibration scheme of thermal resistance. Besides, according to the detailed analysis of the factors affected the accuracy of calibration, this paper supply a measure to solve this problem. This calibration design described in the article can achieve high-precise, digital calibration of the thermal resistance thermometer.
