Pay attention to these points when using an infrared thermometer How to operate the thermometer
How to use the infrared thermometer
1. Go to the site to be tested and take out the infrared thermometer from the box;
2. Hold the handle of the thermometer with your right hand, and pull the switch with your index finger. You will hear the sound of "BI-BI". When the power is turned on, the screen will display the temperature of the object you are facing; pay attention to the distance coefficient K when measuring. Machine K=D:S=12:1, the popular understanding is that when the measurement range is 12m away, the area of the measured object is a circle with a diameter of 1 meter. If there is an object with a diameter of 1m at a distance greater than 12m, the temperature of the measured object will be inaccurate .
3. To measure an object, point the lens at the object to be measured, press and hold the switch to measure, and the SCAN symbol will appear on the upper left side of the screen, indicating that the measurement is in progress; release the switch, and the HOLD (HOLD) will appear on the upper left side of the screen ) symbol, which is displayed on the screen is the temperature of the measured object.
4. To use the instrument in an environment with unclear sight or darkness, first release the power switch button; then press the laser/backlight (LASER/BACKLIT) button, and the laser/backlight symbol will be displayed on the screen, which is Press the switch to measure, and you will see red dots appear on the measured object, indicating that the temperature of the area is being measured. When not in use, release the power button, then press the laser/backlight button, press once without laser, press twice without backlight, press three times without backlight and laser.
5. When testing a surface (such as airtight), the fixed-point method can be used, and it must be recorded in time for each measurement. The measurement data is automatically kept for 7 seconds, and if there is no operation, it will automatically shut down in 30 seconds. The backlight turns off automatically after a ten-second delay.
Precautions for infrared thermometers
1. Only the surface temperature is measured, and the infrared thermometer cannot measure the internal temperature.
2. The wavelength above 5um cannot be used for temperature measurement through quartz glass. Glass has very special reflection and transmission characteristics, which does not allow accurate infrared temperature readings. But the temperature can be measured through the infrared window. Infrared thermometers may not be used for temperature measurement on bright or polished metal surfaces (stainless steel, aluminum, etc.).
3. Locate the hot spot. To find the hot spot, the instrument aims at the target, and then scans up and down on the target until the hot spot is determined.
4. Pay attention to environmental conditions: steam, dust, smoke, etc. It blocks the optical system of the instrument and affects accurate temperature measurement.
5. Ambient temperature. If the thermometer is suddenly exposed to an ambient temperature difference of 20°C or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.
6. In order to avoid damage to the infrared thermometer, please use compressed air to remove large particles and dust first, and then wipe it with a piece of cloth. particles and dust, then wipe with a cloth
7. Gently use slightly moistened non-corrosive solution or mild diluted soap solution (solution or mild diluted soap solution (never use soluble soft cotton cloth to wipe the lens (do not immerse the cloth in liquid) Wipe the lens with a soft cotton cloth (do not soak the cloth in liquid.) Use a clean computer monitor cleaning cloth to gently wipe the display.
8. Gently wipe the display with a clean computer monitor cleaning cloth. To clean the infrared thermometer body: To clean the thermometer body: Gently wipe the thermometer body with a clean, slightly damp cloth.
9. Use a clean slightly damp cloth to gently wipe the body of the thermometer. Dampen the cloth with a solution of water and a little mild soap if necessary. If necessary, dampen the cloth with a solution of water and a little mild soap.
10. After use, please cover the infrared thermometer with the lens cover as soon as possible, and put it away.
