In this paper, we propose a user-friendly tool that calibrates the coefficient variables of Steinhart-Hart equation used for the temperature measurement of NTC thermistor. The proposed tool provides automatic modification of the coefficient variables only with temperature measurement, whereas the legacy process requires manual modification of the coefficient variables with temperature and resistance measurements. For user convenience, the proposed tool is implemented with a user-friendly GUI program. The tool is applied to 4-points temperature measurements of PCR devices. In accuracy evaluation, the proposed tool yields a precision of ±0.1℃.
