Correct usage of electronic thermometer?

1. Power on: Press the switch button of the electronic thermometer briefly, and the display screen of the electronic thermometer will display 8E for about 2 seconds, and the last measured temperature value will display for about 2 seconds. After 36.5℃ is displayed again, the unit symbol℃ flashes or goes down, indicating that measurement can be started. The default unit "℃" is set in the factory.

2. Measurement of underarm temperature: Before measurement, the arm naturally droops and the underarm is tightly closed for more than 3 minutes to stabilize the underarm temperature, and the thermometer temperature probe is placed in the center of the underarm to ensure that the thermometer temperature probe is completely covered and is not affected by air. The normal axillary temperature is about 35.0℃~37.0℃. In order to measure the armpit temperature stably, it is suggested that the armpit temperature should be measured for about 5 minutes after the symbol "C" or "F" on the display screen stops flashing and makes a slow "BIBl" sound for 4 times.

3. Measurement of oral temperature: Measure the lip before closing for about 1 min to stabilize the oral temperature. Put the thermometer's temperature sensor at the root of the inner sublingual side, close your mouth and keep breathing through the nasal cavity to avoid the influence of inhaled and exhaled gas on temperature measurement. The normal oral temperature is about 35.5℃~37.4℃. In order to achieve stable oral temperature measurement, it is suggested to continue measuring oral temperature for about 5 minutes after the symbol "C" or "F" on the display screen stops flashing and makes a slow "BIBl" sound for 4 times.

4. If the measured temperature is greater than 37.5℃, you will hear the electronic thermometer make three short "BIBl" sounds for four times, indicating that the electronic thermometer has finished measuring, and give an over-temperature warning.

5. Unit conversion setting: Convert from Celsius to Fahrenheit. Press and hold the switch button when closing. When the symbol on the screen changes from C to F, release the button and the conversion is successful. On the contrary, from F to C, hold down the switch button when closing. When the symbol on the screen changes from F to C, release the button and the conversion is successful.

6. Just turn it off at last.
