ABSTRACT:
An electronic thermometer includes a temperature sensing means for sensing a temperature of a part to be measured, and a prediction means for calculating an equilibrium temperature according to the temperature being sensed. The prediction means includes a parameter determination unit for calculating parameters of a prediction function having three parameters to obtain an equilibrium predicted temperature, and an equilibrium predicted temperature calculation means for calculating an equilibrium temperature during a period of the thermal equilibrium time, based on the parameters determined by the parameter determination unit. The parameter determination unit determines parameters held by the prediction function, based on three (or two) sensed temperatures and the measuring times thereof. According to the prediction function, the equilibrium temperature can be predicted with a small number of samplings, and the parameters are determined based on the sensed temperature and the measuring time of the sensed temperature. Consequently, the number of samplings to predict the equilibrium temperature is reduced, as well as solving a problem that the equilibrium temperature may be varied due to an external factor, individual difference, and the like.
