Wall-mounted Non-contact Infrared Thermomter operation steps

When using the Wall-mounted Non-contact Infrared Thermomter, 1. Point the machine at the measured object and press the button. At this time, pay attention to the ratio between the distance and the measurement area. The machine is equipped with a laser light for aiming at the measured object.
2. Object distance ratio (D:S) refers to the ratio of the measured distance to the surface area of the measured object. When the distance between the thermometer and the measured object increases, the surface area of the thermometer and the measured object is required to be larger. D:S=12:1
3 The observation range must ensure that the measured target is larger than the measurement area of the machine. The minimum diameter of the measured area must be above 1.5 square centimeters.
4 Reflectivity The emissivity of most organic materials and paint or oxidized materials is 0.95 (has been set in this machine). Smooth or polished metal surfaces may cause inaccurate measurement values, which must be covered on the surface for compensation Tape or black paint, and wait to make it the same temperature as the material underneath, and then take the temperature measurement.
5 Press the battery switch, install the battery correctly, press the switch button to turn on, the LCD displays the battery symbol, the temperature value, and the value retention time is about 7 seconds.
