The operating steps of high-resolution infrared thermometer to measure temperature:
1. Go to the tested location and remove the instrument from the box;
2. Grasp the thermometer handle with your right hand and press the switch with your index finger. You will hear a "biu biu" sound, turn on the power, and the screen will display the temperature of the object you are facing. When measuring, pay attention to the distance coefficient.
3. To measure an object, align the lens with the object being measured, press and hold the switch to perform the measurement. At this point, a scanning symbol will appear on the upper left side of the screen, indicating that the measurement is in progress. Release the switch, and a hold symbol will appear on the upper left side of the screen, which displays the temperature of the object being measured.
4. When using this instrument in unclear or dark environments, first release the power switch button, then press the laser/backlight button. This will display the laser/backlight symbol on the screen. When the switch is pressed for measurement, a red dot will appear on the object being measured, indicating that temperature measurement is being conducted in that area. When not in use, release the power button and press the laser/backlight button again. Press once for no laser, press twice for no backlight, and press three times for no backlight and laser.
5. When testing a surface (such as a sealed one), the fixed-point method can be used, and each measurement must be recorded in a timely manner. The measurement data is automatically held for 7 seconds without any operation, and automatically shuts down after 30 seconds. The backlight will automatically turn off after a delay of ten seconds.
What are the main considerations when choosing a high-resolution infrared thermometer?
1. Temperature range: The temperature range of the product, each model of thermometer has its specific temperature measurement range, and the temperature range of the selected instrument should match the temperature range of the specific application.
2. Target size: When measuring temperature, the target being measured should be larger than the field of view of the thermometer, otherwise there may be measurement errors. It is recommended that the size of the target being measured exceed half of the field of view of the thermometer.
3. Optical resolution: the ratio of the diameter of the thermometer probe to the target diameter. If the thermometer is far away from the target and the target is small, a high-resolution thermometer should be selected.
