1. Ambient temperature. If the infrared thermometer is suddenly exposed to an ambient temperature difference of 20 degree or higher, allow the instrument to adjust to the new ambient temperature within 20min.

2. Measure only the surface temperature of the object. Portable infrared thermometer can not measure the internal temperature of the object

3. Pay attention to the environmental conditions. Steam, dust, smoke, etc. will block the optical system of the instrument and affect the precise. Accurate temperature measurement.

4. Locate hot spots. To find the hot spot, first aim at the target with the instrument, and then scan up and down on the target until the hot spot is identified.

5. Portable infrared thermometer can not be measured through the glass. Glass has very special reflective and transmissive properties, can not carry out precise. Accurate temperature readings, but can be measured through the infrared window. Infrared thermometers are best not used on bright or polished glass. Best not used for bright or polished metal surfaces temperature measurement (stainless steel, aluminum, etc.).

1, to avoid damage to the infrared thermometer, please first use compressed air to remove large particles and dust, and then wipe with a piece of cloth.

2, gently use a slightly dampened marked for cleaning the lens of a non-corrosive solution or a mild diluted soap solution (solution or a mild diluted soap solution (never use a dissolved soft cotton cloth to wipe the lens (do not immerse the cloth into the liquid) agent) of a soft cotton cloth to wipe the lens (do not immerse the cloth into the liquid). Use a clean computer monitor cleaning cloth to gently wipe the display.

3. Gently wipe the display with a clean computer monitor cleaning cloth.

4. Gently wipe the body of the thermometer with a clean, slightly damp cloth. If necessary, wet the cloth with a solution of water and a small amount of mild soap.

5, when the use is completed, please cover the infrared thermometer lens cover as soon as possible, and put into the carrying case for storage.
