This product is an inferred 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. The supported operating system through verification
includes: win XP, win7, win 8, win10, Apple system. It is suggested to use
the attached USB cable or USB cable with higher quality.
The product can be used in fields of medical treatment, fire fighting,
archaeology, traffic, agriculture, geology, energy, smelting, electronic
manufacture, etc and is the ideal selection for electrician and maintenance
personnel and technicians and can be used to find the problem area
quickly.
The following major functions increase the product’s 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.

The product belongs to precision electronic and sensitive optical devices.
Don’t impact and drop it to avoid damage.
Don’t dismantle and remodel the products.
When the product works, there is light sound of clicking every several
seconds. This is normal phenomenon that the lens captures images.
Please use damp cloth or weak soap to clean the enclosure of the device.
Don’t use abradant, isopropanol or solvent to clean. Special optical lens
cleaner is used to clean the screen.

“ ” key and the screen bottom will display highest/lowest
temperature column. Press “ ” can also hide it.
5.1 Charging: the product is provided with built-in 1800 lithium battery.
When the battery power is not sufficient, please charge it through Micro
USB interface in time.
5.2 On/off key: hold down “ /MENU ” key to power on /off.
5.3 Switching between infrared thermal image and visible image: press
“ ” or “ ” key to switch the degree of fusion between inferred
thermal images and visible images (the degree of fusion is 0%, 25%,
50%, 75% and 100%).

5.1 Charging: the product is provided with built-in 1800 lithium battery.
When the battery power is not sufficient, please charge it through Micro
USB interface in time.
As shown in the figure, press “ /MENU” key to select “image” option in the
main menu. 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.
When viewing the images, the screen will show the prompt of “Delete photo？
” by pressing “ ” key. If “yes” is selected at the moment, press “ /MENU”
key to determine to delete the image. If “no” is selected, press
“SELECT/ENTER” key to determine not to delete the image.
The menu of color palette can change the false color of infrared thermal
image. The product provides five types of color palette: rainbow, iron oxide
red, cold color, white heat and black heat.
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 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.
The product is provided with four types of object measurement modes:
Coarse object (0.95)
Semi-matte object (0.85)
Semi-shiny object (0.60)
Shiny object (0.30)
According to the characteristics of the measured objects, users may set the
emissivity value through the “self-define” option (please refer to the table of
“emissivity of common materials”).
As shown in the figure, press “ /MENU” key to enter the main menu and
select “emissivity” option and press “ ” key to enter the emissivity list.
Press “ ” and “ ” keys in navigation key to select the emissivity. Then
press “SELECT/ENTER” key to determine selection of the emissivity. Press
“ ” key again to return.
