How to use the thermometer with three buttons of the temperature gun?

Lead: Body temperature gun is a popular temperature measuring tool in epidemic period, because it has the characteristics of fast measuring speed, safe use and wide range. The use of temperature gun needs the correct method. So, do you know how to use the three buttons of the temperature gun? What are the precautions when using a thermometer?

How to use the three buttons of the temperature gun

1. Generally, there are setting keys, plus (+) keys and minus (-) keys on the temperature gun. First of all, you need to turn on the power supply and press the setting key once, so you can switch the setting between body temperature and body surface temperature.

2. Press and hold the setting key for more than 3 seconds, and the F 1 option will appear, which can be used to set the degree of day and switch between Celsius and Fahrenheit.

3. After setting the F 1 option, press the setting key again to enter the F2 option, which can be used to set the alarm temperature value.

4. After setting the F2 option, press the Set key again to enter the F3 option, which can be used to set the temperature error value.

5. After setting the F3 option, press the setting key again to enter the F4 option, which is used to set the sound of the thermometer, and the sound can be turned on or off.

6. After setting F4 option, press the setting key again, and the temperature gun will be turned off. When the temperature gun is turned on again, it will work in the newly set mode.

Is temperature measuring gun's temperature measurement accurate?

Under normal circumstances, it is generally accurate to measure temperature with temperature measuring gun. However, because temperature measuring gun measures the body surface temperature of human body, many factors will lead to inaccurate measurement due to external factors. When temperature measuring gun is used to measure temperature, it is easily influenced by air and temperature. If the weather is cold outside, the face, hands and other limbs are exposed, which will easily affect the measurement. If you want to measure data more accurately, you need to measure it in a place covered by clothes.

The operation method of the temperature gun is mainly to aim the infrared detector at the center of the forehead above the eyebrows, keeping it horizontal and vertical, about 3-5cm away from the forehead. For example, mercury thermometers are used to measure the mouth, armpits and other parts. Because it measures the inside of the human body, there will be no great external factors, so the data of the thermometer is more accurate than that of temperature measuring gun. In addition, if you want to use temperature measuring gun to measure more accurate data, you need to rest for a few minutes in a quiet environment and take multiple averages. The advantage of temperature gun is fast and safe. Measurement can save time, especially in the face of infectious diseases and a large number of people who are prone to catch a cold, so it will be more convenient to use temperature measuring gun.

Matters needing attention in the use of thermometer

(1) Mercury thermometer: The thermometer (oral and anal instruments) should be disinfected by one person; The anal surface, axillary surface and oral surface should be put into different containers for disinfection and preservation. After disinfection, dry it and save it for later use.

(2) Electronic thermometer: it should be disinfected once every two weeks if it is not used for a long time. In addition to paying attention to disinfection, we should also check whether the power is sufficient. Too low power will affect the test results. Do not place in high temperature and high pressure environment, and do not touch corrosive substances.

(3) Infrared thermometer:

1. Ear temperature gun: Because there is liquid in the ear canal, the accuracy of ear temperature gun will be greatly affected, so users with otitis media are not suitable to use ear temperature gun.

2. Forehead thermometer: When the room temperature exceeds 25 degrees Celsius and the room temperature is lower than 20 degrees Celsius, the forehead thermometer is easily affected by the ambient temperature, including sweating and blowing air to turn on the air conditioner, which will have a certain impact on the forehead temperature collection.

Why can't I take my temperature often?

Frequent temperature measurement is meaningless for clinical diagnosis and disease control, so frequent temperature measurement is not recommended.

Under normal circumstances, the body temperature is regulated by the thermoregulatory center, and frequent measurement of the body temperature in a short time will not change significantly, so it is meaningless to measure the body temperature at this time for clinical diagnosis.

If the person whose body temperature is measured is in the fever stage, if the body temperature is measured frequently, it may cause the body to catch cold, which may lead to the aggravation of the disease. At this time, it takes a while for the body temperature to drop, and the body temperature is often measured. At this time, there is no obvious change in body temperature, and anxiety may occur, which is not conducive to controlling the disease. If you want to observe the change of body temperature, you can take your temperature once an hour or so. If the body temperature exceeds 38.5℃, acetaminophen tablets, ibuprofen sustained-release capsules and other antipyretics should be used according to the doctor's advice. However, if the body temperature does not exceed 38.5℃, it is not recommended to use drugs rashly, and physical cooling methods such as warm water wiping or alcohol wiping can be used for treatment.

If you use an underarm thermometer to measure your body temperature, you need to reset the thermometer to zero before measuring your body temperature, and you should not move it frequently during the measurement, otherwise the measurement result may be affected.
