Hua'an is a medical thermometer chinese manufacturer
,With the development of modern science and technology and industrial technology,temperature measurement techniques are constantly improved and enhanced.
1. thermometer before use, you should use alcohol to disinfect the thermometer head.
2. Push switch, the buzzer beeps once, the display shown in Figure A, for about 2 seconds.
Digital thermometer display information notes
3. Then the display shows the temperature of the amount shown in the last side B (if the last measurement was 36.5 ?), well last about 2 seconds.Then the display may show C as shown in Fig. "?" symbol flashes to indicate that the thermometer has been pending side state. (So when the room temperature is higher than 32 ?,the thermometer will display the temperature instead displayed as shown in Figure D, while "?" is blinking).
4. The thermometer used to take temperature. When body temperature shows the temperature values gradually increase, while "?" is blinking.
5. When the rate of temperature rise within 16 seconds is less than 0.1 ?, "?" symbol stops flashing, issued about 5 seconds while the thermometer beep tone, when the thermometer measurement is completed, you can read the displayed temperature value.
Turn the thermometer
Rotary thermometer is made of a bimetal curl. One end of the bimetal is fixed, and the other end connected to the pointer. Two metal sheets due to different degree of expansion, at different temperatures, resulting in different bimetal curl, pointer finger in a different location then followed on the dial, from the reading on the dial, you can know the temperature.
The change in resistance of the semiconductor and the metal type, the temperature, the resistance has decreased, and the fluctuation range. Therefore, a small amount of temperature change can produce significant changes in the resistance thermometer made of a higher precision temperature control is often called.
