In order to measure the temperature, aim the instrument at the object to be measured, press the trigger to read out the temperature data on the LCD of the instrument, and ensure that the ratio of the distance to the spot size and the field of view are arranged.
Some problems should be paid attention to when using infrared thermometer
1. Only the surface temperature is measured, but the infrared thermometer cannot measure the internal temperature.
2. It is impossible to measure the temperature through the glass. The glass has very special reflection and transmission characteristics, and accurate infrared temperature reading is not allowed. But the temperature can be measured by infrared window. It is better not to use infrared thermometer to measure temperature on bright or polished metal surface (stainless steel, aluminum, etc.).
3. To locate the hot spot, the instrument aims at the target, and then scans up and down the target until the hot spot is determined.
4. Pay attention to environmental conditions: steam, dust, smoke, etc. It blocks the optical system of the instrument and affects the accurate temperature measurement.
5. Ambient temperature: if the thermometer is suddenly exposed to an ambient temperature difference of 20 ℃ or higher, it is allowed to adjust to a new ambient temperature within 20 minutes.
