Abstract: A thermometer is provided with a ROM, in which a program for controlling a CPU and plural predetermined emissivity data are memorized, and is further provided with a RAM having plural registers, in which plural emissivity data are entered and memorized. One of these memorized emissivity data is selected and used for measuring a temperature of an object. The selected emissivity data and an output of a temperature sensor are amplified by an amplifier, and are supplied to an A/D convertor to obtain digital data. The CPU processes the digital data to obtain temperature data, and displays the obtained temperature data. With this structure of the thermometer, emissivity data can be set with a simple operation.

Abstract: An electronic device with a sensor displays in colors, in accordance with values measured by the sensor, information associated with the values. When a temperature measurement mode is selected, a control unit (11) causes a temperature sensor (21) and a measuring circuit (20) to detect a temperature of snow, and writes data of the detected temperature of snow in a temperature data register (C) of a display register (40) of a RAM (12). The control unit (11) also reads display color data, corresponding to a company name of a ski wax maker stored in a company name register (N) of the RAM (12) and a value of the temperature data register (C) of the display register (40), from a color conversion table of a ROM (13) which stores display color data representing index colors of ski wax of the respective ski wax makers.

Abstract: When a lap switch is operated, data of a lap time stored in a register T is stored in a lap register pointed out by a pointer PR. An average pace for a section of a course is calculated on the basis of data of a step count for that section stored in a register H and data on the lap time for that section stored in the register T. Data on a calculated average pace is stored in a lap register. A pace difference between the present and the immediately preceding average pace is calculated and data on the pace difference is stored in an appropriate lap register. Thereafter, the pointer PR is incremented by one.
