Avoid damage to probe of the product

Note: don't put the product close to strong heat source directly (such as electric iron). Otherwise, it may damage the probe of the product.

Product hum

When the product works, there is light sound of clicking every several seconds. This is normal phenomenon that the lens captures images.

Warning

The warning describes the acts that may cause harm to users. Please observe the following operations in order to avoid electric shock or personal injury.

- If the product case is damaged, do not use it continuously.

Please contact the local distributors or agents of the company under such conditions.

- During the process of use, if the product is found with smoke, spark, or a burnt smell, please stop using it at once.

In case of such conditions, the product power supply should be powered off first. After the smoke and peculiar smell disappear completely, please contact the local distributors or agents of the company.

- Do not remodel the adapter and the data line.

Otherwise, such remodeling may cause short circuit or fire.

- Do not weld the battery without permission.

Such operation may damage the battery and result in leakage and explosion of the battery.

- Avoid that the battery is impacted (such as collision and falling, etc.).

Such conditions may damage the battery case or result in the battery leaking or exploding.

- Please pull off the adapter from the power socket when charging is not being performed.

The adapter may get overheated if it is connected with power supply for a long time. This may cause overheating, deformation, and fire.

- Please ensure that the plug of the adapter is inserted into the specified power socket.

The adapter plug may be different due to the regions. Please make confirmation whether the specification of the adapter is consistent with the specification of electric appliances in your region. Otherwise, this may cause overheating of the equipment, electric shock, fire, chemical leakage inside the battery, explosion, and other serious consequences.

- When the plug of the adapter or wire is damaged, stop using it immediately.

Do not change the battery unless the plug of the charger is completely inserted into the socket.

Preliminary Acquaintance with Infrared Thermal Imager

For a long time, infrared thermal imaging detection technology has become an important means to ensure industrial safety in developed countries. Its application fields include electric power, metallurgy, petrochemical, machinery, coal, transportation, fire control, and national defense. It can perform real-time detection of production and equipment at high voltage, high current, and high speed, without the need to power off the supply, stop the machine, or halt

production, thus identifying potential problems and preventing malfunctions. This "non-contact" modern detection technology is safe, reliable, and quick. It represents a technical revolution compared to traditional contact detection methods. Infrared thermal imaging technology is widely used in the following fields:

● Inspection of power equipment, transmission lines, and transformers; - Hidden fire source search in fire protection; - Personnel search and rescue in fires, and fire command; - Analysis of leak points and heat loss in heat pipes and heating equipment; - Determining the location of heating faults in operating trains; • Night monitoring by security departments.

Overview

This product is a single handheld device that is light and portable, simple to operate, and suitable for a wide range of applications. It provides comfortable viewing and clear, detailed thermal imaging, making it an ideal tool for outdoor use. It supports a variety of pseudo-color patterns with one-click switching, allowing you to quickly distinguish the location of targets in the scene. You can capture thermal images and save them to the device, then transfer them to a computer via USB for report generation and printing.

Cleaning of the Products

Please use a damp cloth or weak soap to clean the enclosure of the device. Do not use abrasives, isopropanol, or solvents to clean. The lens and screen should be cleaned with cleaning agents for professional optical glasses.

Lens Maintenance

Prevent damage to the infrared lens:

• Clean the infrared lens carefully. The lens is provided with a refined anti-reflection coating.
• Do not clean with force to prevent damage to the anti-reflection coating. The selectable color palette.
• Use a cleaning solution for lens maintenance, such as alcohol-based commercial lens cleaners, alcohol, and a lint-free cloth or paper towel. Compressed air tanks can be used to remove loose particles.

Clean the lens:

• The compressed air tank or dry nitrogen ion gun (if applicable) may be used to blow the loose particles on the lens surface.
• Dip the lint-free cloth in alcohol.
• Squeeze the excessive alcohol from the cloth or apply the lint-free cloth on a dry cloth lightly.
• Wipe the lens surface by making circular motions. Then discard the cloth.
• If it is necessary to repeat the above step, please use a new cloth dipped in the cleaning solution to wipe.

4. Introduction to “Color Palette” Sub-menu

4.1. Color Palette Description

The palette can be used to change the pseudo-color display of the infrared image on the display. Some color palettes are better suited for specific applications and can be set up as needed.

The palette is divided into five palettes: rainbow, iron, cold color, white hot, and black hot.

These palettes work best with high thermal contrast and provide additional color contrast between high and low temperatures.

Suitable selection of color palette displays the details of the target objective better. Rainbow, iron, 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 hot and white hot color palettes provide even linear color.

The following is the image of the same object with selection of different color palettes.

Iron, Rainbow, Cold color, White hot, Black hot

5. Introduction to “Emissivity” Sub-menu

5.1. Emissivity Description

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 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.

5.2. Emissivity Setting

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”).

The operation steps are as follows:

Press the “ ⏻ /MENU” button to go to the main menu, from the main menu, by touch, click on the “Emissivity” to go to the sub menu or by the Navigation button, select the “ Emissivity ” sub menu, and press the “SELECT/ENTER” button to go to the sub menu, as shown in the figure below:

For the four kinds of emissivity above, touch and select the emissivity, or press the “▲” or “▼” Navigation button to select the emissivity, and then press the “SELECT/ENTER” button for the selection, and finally, touch

and click on the left upper corner to return or press the “ ⏻/MENU” button to return to be able to set the emissivity successfully. If you touch to select “User defined” emissivity to go to the editing state, or press the “▲” or “▼” Navigation button to select “User defined” emissivity, and then press the “SELECT/ENTER” button to go to the editing state, as shown in the following figure:

Touch and click on the corresponding columns on the screen, and then touch and click on the “▲” or “▼” button to set the corresponding values, or by the “▶” or “◀” Navigation button, select the corresponding columns, and then by “▲” or “▼” Navigation button, set the corresponding values. After modification, touch and click on the left upper corner to return or press the “○/MENU” button to return to be able to set the emissivity successfully.
