PURPOSE:To make it possible to measure body temp. rapidly enough with high accuracy, by estimating convergent body temp. by calculating constant different at every indivisual body on the basis of the logarithmic value of time differentiation of detection output at every calculated sample time. CONSTITUTION:When a switch 7 is turned on, an initial temp. value is taken in CPU3 through an A/D converter 2 and, when a sample time arrives succeedingly, the temp. detected when said temp. value is taken in through the A/D converter 2 is stored in RAM5. In the next step, the time differentiation value of the detected temp. is calculated and the logarithmic value of this time differentiation value is further calculated to be stored in RAM5 along with the sample time at that time. When the number of times of the sample times at every indivisual is calculated on the basis of the stored data and the logarithmic value. Succeedingly, convergent temp. is calculated by a predetermined formula to be displayed by a display device 6. By this method, highly accurate measurement can be performed rapidly enough. |
