! 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. 2 Table of contents Catalog

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. Shutdown prompt 12 3.2 Common sense of safe use of battery The battery shall be stored at the ambient temperature of -20 and 20 as much as possible. 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 will reduce the capacity of the battery. Charging 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. 13 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. 14 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 the setting icon at the bottom right of the 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:
