ELECTRONIC SMALL-SIZED CALCULATOR

PURPOSE:To enable storage and display of the max. tepm., min. temp., and respective time by providing a temp. measuring function and a clocking function. CONSTITUTION:A temp. measuring circuit 1 detects a temp. change as a voltage change, converts the same to a frequency change and supplies the frequency change to a counter 2 of a calculator 17. A reference signal generating circuit 18 forms a 1-sec signal and supplies said signal to the calculator 17. The frequency count value is converted to a temp. value in the calculator 17 and is stored together with the measuring time to an RAM5, and thereafter the measured value of this time is compared with the measured value up to the previous time and the max. value and min. value are stored together with the measuring time in the RAM5. The time measurement is accomplished by counting the time with the 1-sec signal and the time data is stored in the RAM5. The stored max. temp., min. temp. and measuring time are displayed on a display part 10 according to the input of a key 8.
