PURPOSE:To make it possible to select and display the maximum and minimum temperatures and the measured times by switching operation, by memorizing and displaying the maximum and minimum temperatures and their measured times. CONSTITUTION:The output of a temperature sensor 1 is written into a microprocessor 3 through an AD converter 2. A clock signal from an oscillator 4 for the watch is written into the microprocessor 3 through a time piece counter 5. The maximum and minimum temperatures are stored in a read-write memory 8 at a one minute interval through the program in an ROM7. In response to the input of the data which is higher than the maximum temperature or the data which is lower than the minimum temperature, the contents in the memory 8 are rewritten, and the times are also rewritten. The measurement is performed throughout 24hr a day, and the maximum or minimum temperature and the time are selected and displayed on a display device 9 through a switch 6. |
