Warning

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

- If the product case is damaged, don't use it continuously.

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

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

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

- Don't remodel the adapter and the data line.

Otherwise, such remodeling may cause short circuit or fire.

- Don't 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 collusion and falling, etc).

Such condition may damage the battery case or result in that the battery leaks or explode.

- Please pull off the adapter on the power socket when charging is not made.

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 consist 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 immediately.

Don't change the battery unless the plug of the charger is inserted into the socket completely.

- Do not touch the electric wire with wet hands.

It is possible to cause electric shock when touching the electric wire with wet hands. When pulling out the electric wire, hold the electric wire head rightly to pull out the wire. Don't pull off the electric wire directly. Otherwise, the electric wire may be broken, causing electric shock and fire.

- Forbid dip the product into water caught in rain.

If the case contact with any liquid, please wipe it dry immediately. If water or other liquid enters the inside of the instrument, please power off the power supply at once. Continuous use may result in product damage.

- Clean the dust on the adapter plug and the data line.

When it is exposed to dusty and dump environment for a long time, the dirt surrounding the electric equipment will accumulate moisture. This may cause short circuit and fire.

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. The application field includes electric power, metallurgy, petro-chemistry, machinery, coal, traffic, fire control and national defense, etc. It can not only carries out real-time detection at high voltage, high current and high speed operation to perform real-time detection for production and instrument but also need not power off the power supply, stop the machine or stop the

production to find the potential problems and prevent occurrence of malfunction. The “non contact” modern detection technology is safe, reliable and quick. It is a type of technical revolution compared with traditional contact detection method. The infrared thermal imaging technology is widely used in the following fields:

● Power equipment, transmission, transformer line inspection;
- Hidden fire source search in fire protection;
- Personnel search and rescue in the fire, and fire command;
- Analyze the location and heat loss of leak points in heat pipes and heating equipment;
- Determining the location of the heating fault of the operating train;
• Security department night monitoring.

Overview

Press the “/MENU” button to return and quit the menu.

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 tune Swatches are better suited for specific applications and can be set up as needed.

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

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, 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 the 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 outenergy. For semi-matte objects that give out less energy, 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 measure ment 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:

Custom 1 0 0

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.
