1. Go to the measured place 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, and you will hear the sound of "beep-beep". When the power is turned on, the temperature of the object you are facing will be displayed on the screen. Pay attention to the distance coefficient k when measuring. The local machine K=D:S= 12: 1, which is generally understood as measuring when the measuring range is outside 12m.
3. When measuring an object, aim the lens at the measured object and press and hold the switch to measure. At this point, a scanning symbol will appear at the top left of the screen, indicating that measurement is being made. When the switch is released, a holding symbol will appear on the upper left of the screen, which is the temperature of the measured object.
4. To use the instrument in unclear or dark environment, first release the power switch button, and then press the laser/backlight button, which is the symbol of laser/backlight displayed on the screen. This is the measurement by pressing the switch, and you will see a red dot on the measured object, indicating that the temperature is being measured in this area. When not in use, release the power switch, then press the laser/backlight button, click No Laser, press No Backlight twice, and press No Backlight and Laser three times.
5. When detecting a surface (such as air tightness), the fixed-point method can be used, and each measurement must be recorded in time. The measurement data is automatically saved for 7 seconds, and automatically turned off for 30 seconds without operation. After ten seconds, the backlight automatically turns off.

Main considerations in selecting infrared thermometer
1. temperature range: the temperature range of Raytek products is -50~3000 degrees (in sections), and each type of thermometer has its specific temperature range. The temperature range of the selected instrument should match the temperature range of the specific application.
2. Target size: When measuring temperature, the target to be measured should be larger than the field of view of the thermometer, otherwise there will be errors in measurement. It is suggested that the size of the measured object should exceed 50% of the field of view of the thermometer.
3. Optical resolution (D:S): that is, the ratio of thermometer probe to target diameter. If the thermometer is far away from the target and the target is small, you should choose a thermometer with high resolution.
Accurate temperature measurement skills 1, when measuring the surface temperature of luminous objects, such as aluminum and stainless steel, the reflection on the surface will affect the reading of infrared thermometer. Before reading the temperature, a rubber strip can be placed on the metal surface, and after the temperature is balanced, the temperature in rubber strip area can be measured. 2. If the infrared thermometer can walk back and forth from the kitchen to the cold storage area and still provide accurate temperature measurement, it will take some time to reach the temperature balance in the new environment before the measurement. It is best to put the thermometer in a place where it is often used. 3. Use infrared thermometer to read the internal temperature of liquid food, such as soup or sauce, which must be stirred before measuring the surface temperature. Keep the thermometer away from the steam to avoid polluting the lens and causing incorrect reading.
