The correct way to measure body temperature is to use a mercury thermometer and an electronic thermometer placed in the appropriate area for measurement. The mercury thermometer is placed in the proper place and taken out after a specified period of time, while the electronic thermometer beeps to read the temperature. If you use a mercury thermometer, the correct way to measure the body temperature is to use the mercury column before shaking to below 35 degrees, dry the armpits and then clip the mercury end to the armpits, 5 to 10 minutes after taking out the value of the reading. Using a mercury thermometer to measure oral temperature, you need to dry the surface of the mouth first, put the mercury end under the tongue, close your mouth, do not bite with your teeth, take it out and read the value after 5 to 10 minutes. If you use an electronic thermometer, the correct way to measure body temperature is to turn on the power, the display Celsius column flashes, indicating that the thermometer is in a state of pending measurement. The Celsius column flashes continuously while the temperature is being measured. When the Celsius bar stops blinking and a beep sounds, the measurement is complete and the value can be read. It is recommended to follow the correct way of measuring body temperature to avoid affecting the normal reading of body temperature.
