2.Safety Information
WARNING
1. Make sure you read all applicable Material Safety Data Sheets (SDS) and warning
labels on containers before you use a liquid. The liquids can be dangerous. Injury to
persons can occur.
2. It is prohibited to use the product in a high temperature above 85 °C or in a low
temperature below-45 °C.
3. It is forbidden to disassemble or refit the thermal camera at will.
4. Do not use too long screws when installing the front/rear mounting bracket, which
may damage the thermal camera.
CAUTION
1. No matter there is a lens cover or not, do not point the infrared thermal camera
towards strong light or equipment with laser radiation. This will affect the accuracy of
the thermal camera and even damage the detector in the thermal camera.
2. Do not use the product under conditions that doesn’t match the environmental
requirements. For specific use environment requirements, see the product parameter
table.
3. Do not apply solvents or equivalent liquids to the camera, the cables, or other
items.
4. Be careful when you clean the infrared lenses. The lens has an anti-reflective
coating which is easily damaged. Damage to the infrared lens can occur with too
much force or cleaning with rough objects such as tissues.

10.1 Measurement Parameters
10.1.1 Setting Emissivity
In order to get more accurate measurement results, you need to set the emissivity according to the target
to be measured before each measurement, instead of using the default configuration. Emissivity refers
to the ratio of the radiation ability of an object to that of a blackbody at the same temperature, which is
relative to the reflectivity of the object. The lower the emissivity, the higher the percentage of energy
reflected, and the higher the emissivity, the lower the percentage of energy reflected. For example,
human skin emissivity is 0.98 and printed circuit board emissivity is 0.91. For more emissivity information,
you can refer to the quick start guide in the package or inquire from other ways.
Emissivity Setting
1. In the thermal imaging interface, press the center button to display the main toolbar
2. select the “Settings” icon on the toolbar，and press the center button to enter the settings menu.
10.1.2 Setting Ambient Temperature
1. In the thermal imaging interface, press the center button to display the main toolbar
2. Select the “Settings” icon on the toolbar，and press the center button to enter the settings menu.
3. Select "measurement parameters" in the list, press the confirm key, and then select "ambient
temperature" to set ambient temperature.
10.1.3 Setting Distance
Different distances will have different effects on the measurement results. For accurate temperature
measurement, the distance information of the object is necessary for compensating for the result.
1. In the thermal imaging interface, click the OK button, and the main menu toolbar will be displayed.
2. In the toolbar, select the "Settings" option and click the OK button to enter "Settings".
3. Select "measurement" in the list, click the confirm button, and then select "distance" to set the distance.
10.2 Temperature Unit
The camera supports temperature displays in degrees Celsius, Fahrenheit, and Kelvin.

10.3 High/Low Temperature Alarm
The camera supports the high and low temperature alarm function. The user can set the high and low
temperature alarm threshold. The alarm function can be turned on or off by setting the "on" and "off"
options. After the high and low temperature alarm is triggered, a prompt icon will appear on the screen. If
the "LED alarm" option is turned on, the LED light will flash promptly when an alarm occurs.
For alarm snapshot function, you can set the alarm snapshot time interval and the number of photos
taken. Turn on this function, after triggering the high and low temperature alarm, it will take pictures
according to the set time interval. When the set number of pictures is reached, the camera will stop taking
photos and this function will be turned off automatically. It needs to be turned on again when it is used.
10.4 Photo-taking Settings
10.4.1 Automatically Save Photos
Turn on this function, the picture will be automatically saved after taking a picture.
10.4.2 Timed Photo
The camera supports the function of taking pictures at regular intervals, and users can independently set
the time interval and number of pictures taken. If this function is turned on, photos will be taken at the set
time interval. After the set number of photos is reached, the camera will stop taking photos and this
function will be automatically turned off.
10.5 Temperature Measurement Gear
The temperature measurement range of the equipment is -20~550℃. In order to ensure the imaging
effect and temperature measurement range, the temperature measurement range is divided into
-20~150℃and 100~550℃. Users can choose different temperature measurement ranges independently
according to the application conditions.
10.6 System Settings
In system settings, you can view the relevant information of this camera, and perform operations such as
restoring factory default settings and formatting the SD card. In the "USB Mode" option, the default is
U-disk mode, and the computer can directly access the SD card in the device through the USB cable. the
option of "USB Camera" is provided in some models, which can synchronize the picture in the camera to
the PC software for real-time display and analysis.
