Preliminary Acquaintance with Infrared Thermal Imager For a long time, infrared thermal imaging detection technology has become an important means to ensure Industrial safety in developed countries. The application field includes electric power, metallurgy, petro-chemistry, machinery,coal, traffic, fire control and national defense, etc. It can not only carries out real-time detection at high voltage, high current and high speed operation to perform real-time detection for production and instrument but also need not power off the power supply, stop the machine or stop the production to find the potential problems and prevent occurrence of malfunction. The non contact modern detection technology is safe, reliable and quick. It is a type of technical revolution compared with traditional contact detection method. The infrared thermal imaging technology is widely used in the following fields:

Power equipment, transmission, transformer line inspection;

Hidden fire source search in fire protection;

Personnel search and rescue in the fire, and fire command;

Analyze the location and heat loss of leak points in heat pipes and heating equipment;

Determining the location of the heating fault of the operating train;

Security department night monitoring. www.xintest.com.cn 7 8 www.xintest.com.cn Overview This product is an infrared camera that integrates surface temperature measurement and real-time thermal image. The traditional inferred thermometer needs to measure every component one by one while it is not necessary for infrared imaging camera, thus saving time. The potential problems may be displayed on color display screen clearly. Moreover, the central point measurement cursor is used to locate quickly and accurately to measure the temperature of the target object. In order to increase the differentiation, the product is provided with a visible light camera. The thermal images and visible images are stored in the device and can be read through USB or stored in a computer to generate a report or for print. With small volume, the product is easy to operate and has strong function. it is the ideal selection for electric power, electronic manufacturing, Industrial inspection and other fields. The following major functions increase the products accuracy and usability:

The radiation coefficient may be adjusted to increase the measurement accuracy of objects with half reflection surface. The highest temperature and lowest temperature cursor may guide the users to the areas with highest and lowest temperature of the thermal images. The selectable color palette. Cleaning of the Products Please use damp cloth or weak soap to clean the enclosure of the device. Dont use abradant, isopropanol or solvent to clean. The lens and screen should be cleaned with use of cleaning agents for professional optical glasses. Lens Maintenance Prevent damage of the infrared lens Clean the infrared lens carefully. The lens is provided with refined anti-reflection coating. Dont clean with force to prevent damage of the anti-reflection coating.The selectable color palette. Use a cleaning solution for lens maintenance, such as alcohol-based commercial lens cleaners, alcohol, and a lint-free cloth or paper towel. Compressed air tanks can be used to remove loose particles. Clean the lens:

The compressed air tank or dry nitrogen ion gun (if applicable) may be used to blow the loose particles on the lens surface. Dip the lint free cloth in alcohol. Squeeze the excessive alcohol in the cloth or apply the lint free cloth on dry cloth lightly. Wipe the lens surface by making circular motion. Then discard the cloth. If it is necessary to repeat above step, please use new cloth to dip with the cleaning solution to wipe. www.xintest.com.cn 9 10 www.xintest.com.cn Charging of the Battery and Description Performance Index Use USB data line to charge:

The product has built-in chargeable 26650 lithium batteries. When the battery level is low, the top right of the screen will display

.Please charge in time through Micro USB interface. Pull off the USB line after fully charging. Note: When the battery is completely empty, there will be an abnormality. It is recommended to use the battery when it is sufficient. To make the lithium ion battery can play the perfect performance:

As shown in the figure, Then press key to enter image list. Press or key in navigation to select the image. Then press SELECT/ENTER key to view image. When viewing the images, press key to view the precious image, Press to view the next image. Press SELECT/ENTER key to return. Press /MENU key to exit from the menu. 2.2. Delete Images While viewing the image, press the button, the screen will display Delete photo? Select "Yes" or "No" to delete the image, press the

" "" " button to Switch the selection, then press the SELECT/ENTER button to confirm.When the image is deleted, No Image will be displayed. Press SELECT/ENTER to return to the menu and press /MENU to exit the menu. 3. Introduction to Color Palette Sub-menu 3.1. Color Palette Description The palette can be used to change the pseudo-color display of the infrared image on the display. Some tune Swatches are better suited for specific applications and can be set up as needed. The palette is divided into: rainbow, iron red, cool, white hot, black hot, five palettes. These palettes work best with high thermal contrast and provide additional color contrast between high and low temperatures. Suitable selection of color palette displays the details of the target objective better. Rainbow, iron oxide red and cold color palettes focus on display of color. Such color palettes are very suitable for high heat contrast and are used to improve the color contrast between high temperature and low temperature. But the black &

white and white & black color palettes provide even linear color. The following is the image of the same object with selection of different color palettes. www.xintest.com.cn 21 22 www.xintest.com.cn 4. Introduction to Emissivity Sub-menu 4.1. Emissivity Description The emissivity of the product can be adjusted from 0.01 to 1.00 with the default value of 0.95. Many common objects and materials (such as timber, water, skin and textile fabric) can reflect the heat energy effectively. So it is easy to obtain relatively correct measurement value. The emissivity is usually set as 0.95 when the coarse objects that are easy to give out energy. For semi-matte objects that give out less energy, the emissivity is usually about 0.85 and the emissivity of semi-gloss objects is 0.6. The shiny objects are divided into materials with low radiation coefficient. The emissivity is usually set as 0.3 at the time of measurement. Correct setting of the value of emissivity is very important for you to carry out the most correct temperature measurement. The surface emissivity will produce giant impact on surface temperature measured by the product. Understanding the surface emissivity will enable you to obtain correct temperature measurement result.
