Operation steps of infrared thermometer to measure temperature
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 directly 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 it is measuring, 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, and 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 each measurement must be recorded in time. 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.
