It's important to note that the performance of infrared thermometers can be influenced by the environment they're used in. Therefore, it's advisable to refer to the user manual to get the best usage methods. Generally, here are the recommended usage guidelines:
- The thermometer should be used in a non-ventilated space and kept away from direct sunlight or heat sources.
- The ambient temperature should be between 10 - 40 °C, and the relative humidity should be between 15 - 90% RH.
- Allow the thermometer to adapt to the surroundings by placing it in a stable environment for at least 30 minutes before use.
- Make sure that the detector is clean by using a cotton swab dipped in alcohol to clean it.
- Clean the area that requires measurement and remove any dirt, hair, or sweat.
- For forehead temperature measurement, direct the detector at the center of the forehead from a distance of 0-5 mm.
