Note, represents the prompt useful information to the user.
Important information please read before using the instrument.
Warning –This instrument has a built-in laser transmitter, do not stare into the laser
beam. The laser specification is 635 nm, 0.9mW, Class II.
Caution-As the thermal imager uses a very sensitive thermal sensor, under any
circumstances (turn on or off) the lens should not be directly aimed at a strong
radiation source (such as the sun,direct or reflected laserbeam, etc.),otherwise it will
Permanent damage to the thermal imager!
Caution-The original packaging box must be used during transportation. Do not
shake or bump the thermal imager strongly during use and transportation.
Caution –It is recommended to use the original packaging box when storing the
thermal imager, and place it in a cool, dry, ventilated environment without strong
electromagnetic fields.
Caution-Avoid oil stains and various chemical substances from staining and
damaging the surface of the lens. After use, please close the lens cap.
Caution-In order to prevent the potential danger of data loss, please copy (backup)
the data to the computer frequently.
Note-The thermal imager may need 3-5 minutes to warm up before reading the data

3.1 Battery installation and replacement
3.1.1 Battery loading and unloading
The batteryis in the instrument handle, and the end of the handle is the batterycover.
Press the U-shaped elastic area on both sides of the battery cover (as shown by the
red arrow) and pull it outward to remove the battery.
When inserting the battery, the battery is designed with a foolproof structure. If it
cannot be inserted, please change the direction and insert it. Push the battery cover
inward and hear a "click", the battery has been installed and self-locked, and the
instrument can be used.

13
3.1.2 Battery replacement
When the battery symbol is empty and flashes, it indicates that the battery is
exhausted and the battery should be replaced at this time. After the instrument displays
the low battery prompt, it will automatically shut down.

3.2 Common sense of battery safe use
The battery should be stored as far as possible at an ambient temperature of
-20℃∽20℃. Because the battery has a small amount of self-discharge during
storage, in order to avoid possible over-discharge during storage and affect the
battery capacity, the battery should be fully charged and stored , And charge it at
regular intervals. The time interval is as follows:
The 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 every 1 month.
Each charge must be more than 50% of the battery capacity.
The batteryshould be charged at an ambient temperature of 0°C∽40°C. Charging at
an ambient temperature of0°C will reduce the batterycapacity. Charging above 40°C
may cause the battery to overheat and cause damage.
! Warning ：

14
! Do not disassemble, squeeze, or puncture the battery;
! Do not short-circuit the external contacts of the battery;
! Keep the battery dry and do not put it in fire or water;
! Do not place it in a place where children can reach;
! Please dispose of used 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, insert it carefully, and
rotate it clockwise (in the direction of the green arrow) by about 50°until it can't rotate (it
has a feeling of locking and positioning).
When removing, turn the lens counterclockwise (in the direction of the red arrow) to
the end, and then take it out carefully.

3.4 Quick start
3.4.1 Get thermal image
After installing the battery, press and hold the power switch of the thermal
imager (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, use the left and right keys or the focus
wheel to adjust the focus of the thermal imager to make the target image clear.
Press the return key to auto focus the thermal imager.
! Note: Unclear focus can cause measurement errors.
3.4.2 Temperature measurement
Move the cross temperature measurement point on the screen to the target
object, the "XX" displayed in the upper left corner of the screen is the
temperature of the target at the temperature measurement point. For details on
adding temperature measurement objects, see "4.2 Temperature Measurement
Mode".
If you want to perform detailed temperature measurement of the thermal image
displayed on the current screen, you can store the thermal image for further
analysis.。
When the target temperature is greater or less than the upper or lower
temperature corresponding to the temperature measurement range of the
thermal imager, the screen temperature will display >XXX℃or <XXX℃to
remind the user.
If you need to set the properties of a temperature measurement object, click on
the object on the touch screen to select it, and then press the setting icon at the
bottom of the screen to enter the property setting menu of the temperature
measurement object. After setting, click the arrow in the upper left corner of the
screen or press the return key to return Active image. The following are the
attribute setting menus for temperature measurement points, temperature
measurement lines, and temperature measurement areas:
