! WARNING, CAUTION AND ATTENTION
Definition
!
A warning represents a dangerous situation or action that could result in personal injury or death.
!
Caution represents a condition or action that may result in damage to the camera or permanent loss of
data.
!
Attention represents useful information for the user.
Important – Read before using the instrument
!
WARNING – This instrument has a built-in laser transmitter. Do not stare at the laser beam. The laser
specification is 635 nm, 0.9 mW, second order.
!
CAUTION – As the camera uses a very sensitive thermal sensor, under no circumstances (power on or
off) should the lens be aimed directly at a strong radiation source (such as the sun, direct or reflected
laser beam, etc.), otherwise the camera will be permanently damaged!
!
Caution-The original packing box must be used during transportation. Do not shake or hit the thermal
imager strongly during use and transportation.
!
CAUTION – It is recommended that the camera be stored in the original container in a cool, dry,
ventilated environment free of strong electromagnetic fields.
!
CAUTION-Avoid staining and damaging the lens surface with oil and various chemicals. After use,
close the lens cap.
!
Caution-To prevent potential data loss, copy (back) the data to your computer frequently.
!
Note-The camera may require a 3-5 minute warm-up period before accurate readings can be taken.
!
Note-Temperature calibration is performed on each thermal imager when it leaves the factory. It is
recommended to perform temperature calibration every year.
!
CAUTION-Do not open or modify the enclosure without authorization. Only authorized personnel of
the company can carry out maintenance.

3Basic operation
3.1 Battery installation and replacement
3.1.1 Battery handling
The battery is in the camera key handle of the instrument, and the end of the handle is the
battery cover.
The battery can be pulled out by pressing the U-shaped elastic area on both sides of the
battery cover and pulling outward.
When inserting the battery, the battery is designed with a fool-proof structure. If it cannot be
inserted, please change the direction to insert it. When the battery cover is pushed inward and a
"click" is heard, the battery has been installed and self-locked, and the instrument can be used.
3.1.2 Replace the battery
When the battery symbol is blank and blinking, it indicates that the battery has been
discharged and the battery should be replaced. The instrument will automatically shut down after
displaying the low power prompt.

3.2 Common sense of safe use of battery
The battery shall be stored at the ambient temperature of -20 ℃ an d 20 ℃ as m uch as possi b l e.
As the battery has a small amount of self-discharge during storage, the battery shall be fully
charged and charged at regular intervals to avoid the possible over-discharge during storage
that may affect the battery capacity. The time interval is as follows:
Ambient temperature is -20 ℃ 20 ℃, once every 6 months;
The ambient temperature is 20 ℃ 45 ℃, once every 3 months;
The ambient temperature is 45 ℃ 60 ℃, once a month.
Each charge must be more than 50% of the battery capacity.
The battery should be charged at an ambient temperature of 0 ℃ 40 ℃. Charging at an
ambient temperature of 0 ℃ w i l l reduce the capaci ty of the battery. Chargi ng at a temperature
above 40 ℃ may cause the battery to overheat and be damaged.
! Warning:
! Do not disassemble, squeeze or stab the battery;
! Do not short-circuit the external contacts of the battery;
! Keep the battery dry and do not place it in fire or water;
! Do not place in a place easily accessible to children;
! Dispose of waste batteries in accordance with local government regulations.

3.3 Lens loading and unloading
Align the red dot of the lens with the red dot in the instrument, carefully insert it to the end, and
rotate it clockwise (in the direction of the red arrow) for about 50 ° until it cannot be rotated (there
is a sense of positioning), and the installation is completed.
When removing, turn the lens counterclockwise (in the direction of the red arrow) to the end, and
then take it out carefully.

15
3.4 Quick start
3.4.1 Get a thermal image
After installing the battery, press and hold the camera power switch (more than 3
seconds) until the power light turns green. After about 15 seconds, the instrument is
initialized and enters the working state.
Open the lens cover, aim at the target, and use the focusing wheel to focus the thermal
imager, so that the target image is clear.
Double-tap the screen to autofocus the camera.
! Note: The focus is not clear, which may lead to measurement errors.
3.4.2 Temperature Measure
Move the cross temperature measuring point in the screen to the target object, and the
"XX" displayed in the upper left corner of the screen is the temperature of the target at the
temperature measuring point. See "4.2 Temperature Measurement Mode" for details of
adding temperature measurement objects.
If you want to measure the temperature of the current thermal image displayed on the
screen in detail, you can store the thermal image for further analysis.
When the target temperature is higher or lower than the upper or lower limit temperature
corresponding to the temperature measurement position of the thermal imager, the screen
temperature will display > XXX ℃ or < X X X ℃ to prompt the user.
If you need to set the attribute of the temperature measurement object, click the object on
the touch screen to select it, and then press thesetting iconat the bottom right ofthe screen
to enter the attribute setting menu of the temperature measurement object. After setting,
click the arrow at the top left corner of the screen to return to the active image. The
following are the attribute setting menus of temperature measuring point, temperature
measuring line and temperature measuring area:

16
Temperature measurement area attribute setting menu
Click the selected temperature measuring point, andpress and holdthe point to drag it
directly within the screen range. There are three items in the temperature measurement
point attribute setting menu: specific radiation coefficient, distance setting and local
parameter. When the local parameter switch is on, the emissivity and distance of a single
temperature measurement target can be set.
Click to select the temperature measuring line, and hold the middle point on the line
to drag the temperature measuring line as a whole; hold any point at both ends of the line
to drag one end of the temperature measuring line to change the direction and length of
the line. The temperature measuring line attribute setting menu has four items: specific
amplitude coefficient, distance setting, local parameter and analysis setting. Under the
analysis setting, there are submenus: maximum temperature, minimum temperature,
average temperature and maximum temperature difference.
Temperature measurement area analysis setting submenu
Click to select the temperature measurement area, press and hold the middle point of
the area to drag the temperature measurementarea as a whole; press and hold anypoint of

17
the four corners of the area to drag the corner of the temperature measurement area to
change the size of the area. The temperature measurement area attribute setting menu has
four items: specific amplitude coefficient, distance setting, local parameter and analysis
setting. Under the analysis setting, there are submenus: maximum temperature, minimum
temperature, average temperature and maximum temperature difference.
If you want to set the temperature measurement object as a "reference object", refer to
"4.8.2 Temperature Measurement Function Settings".
! Note: Only one reference temperature measurement target can be set for the thermal
imager.
