Safety Information

| Make sure you read all applicable Material Safety Data Sheets (SDS) and warning labels on containers before you use a liquid. The liquids can be dangerous. Injury to persons can occur.
---|---
| It is prohibited to use the product in a high temperature above 85 °C or in a low temperature below-45 °C.
| It is forbidden to disassemble or refit the thermal camera at will.
| Do not use too long screws when installing the front/rear mounting bracket, which may damage the thermal camera.
| No matter there is a lens cover or not, do not point the infrared thermal camera towards strong light or equipment with laser radiation. This will affect the accuracy of the thermal camera and even damage the detector in the thermal camera.
| Do not use the product under conditions that doesn’ t match the environmental requirements. For specific use environment requirements, see the product parameter table.
| Do not apply solvents or equivalent liquids to the camera, the cables, or other items.
| Be careful when you clean the infrared lenses. The lens has an anti- reflective coating which is easily damaged. Damage to the infrared lens can occur with too much force or cleaning with rough objects such as tissues.

  • PIP(Picture in Picture):Thermal image is overlaid on the center of visual camera image.
  • Digital Camera:Visual camera image only

Note: In order to achieve better overlay image effect, when using the picture in picture, and thermal fusion modes, you need to set the alignment distance, which is the approximate distance from the thermal camera to the target. In picture in picture/thermal fusion / digital camera mode, please make sure that the thermal image displayed on the screen is aligned with the target.

Shutter Correction

Shutter Correction Introduction
Shutter correction is used to compensate for the non-uniformity of the detector pixels or the non-uniformity caused by other optical interference. When the picture effect is poor, you can perform shutter correction, which is common in situations where the ambient temperature changes rapidly.
Shutter Correction Operation
In the imaging interface, click the return button to perform a non-uniformity correction. During shutter correction, the screen will freeze for a short time, which is normal.

Settings

Setting Emissivity
In order to get more accurate measurement results, you need to set the emissivity according to the target to be measured before each measurement, instead of using the default configuration. Emissivity refers to the ratio of the radiation ability of an object to that of a blackbody at the same temperature, which is relative to the reflectivity of the object. The lower the emissivity, the higher the percentage of energy reflected, and the higher the emissivity, the lower the percentage of energy reflected. For example, human skin emissivity is 0.98 and printed circuit board emissivity is 0.91.
For more emissivity information, you can refer to the quick start guide in the package or inquire from other ways.

Emissivity Setting

  1. In the thermal imaging interface, press the center button to display the main toolbar.
  2. select the “Settings” icon on the toolbar, and press the center button to enter the settings menu.

Setting Ambient Temperature

  1. In the thermal imaging interface, press the center button to display the main toolbar
  2. Select the “Settings” icon on the toolbar, and press the center button to enter the settings menu.
  3. Select “measurement parameters” in the list, press the confirm key, and then select “ambient temperature” to set ambient temperature.

Setting Distance
Different distances will have different effects on the measurement results. For accurate temperature measurement, the distance information of the object is necessary for compensating for the result.

  1. In the thermal imaging interface, click the OK button, and the main menu toolbar will be displayed.
  2. In the toolbar, select the “Settings” option and click the OK button to enter “Settings”.
  3. Select “measurement” in the list, click the confirm button, and then select “distance” to set the distance.

Temperature Unit
The camera supports temperature displays in degrees Celsius, Fahrenheit, and Kelvin.
High/Low Temperature Alarm
The camera supports the high and low temperature alarm function. The user can set the high and low temperature alarm threshold. The alarm function can be turned on or off by setting the “on” and “off” options. After the high and low temperature alarm is triggered, a prompt icon will appear on the screen. If the “LED alarm” option is turned on, the LED light will flash promptly when an alarm occurs.
For alarm snapshot function, you can set the alarm snapshot time interval and the number of photos taken. Turn on this function, after triggering the high and low temperature alarm, it will take pictures according to the set time interval. When the set number of pictures is reached, the camera will stop taking photos and this function will be turned off automatically. It needs to be turned on again when it is used.
Automatically Save Photos
Turn on this function, the picture will be automatically saved after taking a picture.
Timed Photo
The camera supports the function of taking pictures at regular intervals, and users can independently set the time interval and number of pictures taken. If this function is turned on, photos will be taken at the set time interval. After the set number of photos is reached, the camera will stop taking photos and this function will be automatically turned off.

Temperature Measurement Gear
The temperature measurement range of the equipment is -20-550°C. In order to ensure the imaging effect and temperature measurement range, the temperature measurement range is divided into -20-150°C and 100-550°C. Users can choose different temperature measurement ranges independently according to the application conditions.
System Settings
In system settings, you can view the relevant information of this camera, and perform operations such as restoring factory default settings and formatting the SD card. In the “USB Mode” option, the default is U-disk mode, and the computer can directly access the SD card in the device through the USB cable. the option of “USB Camera” is provided in some models, which can synchronize the picture in the camera to the PC software for real-time display and analysis.

Application Scenarios

Warehouse Detecting
With the help of C series handheld thermal camera, warehouse inspection personnel can quickly find abnormal high temperature objects in the warehouse, and take corresponding measures to eliminate potential safety hazards timely. Detecting of Power Distribution Cabinet
The temperature distribution of power distribution equipment can directly reflect the running status of the equipment. Improper contact or damage may cause abnormal high temperature. The inspection personnel can detect anomalies in time to ensure the safety of power distribution equipment. Detecting of Heating Wire of Rear Car Window
The heating wire on the rear car window can defrost and defog to ensure the safety of driving, especially on rainy and snowy days. The whole on-off condition of the heating wire can not be seen through visible light. The whole heating wire can be quickly detected by TR256 series handheld thermal camera to analyze whether the heating wire is broken. HVAC Detecting
TR256 series handheld thermal camera can help HVAC engineers to fully capture the temperature distribution of the measured pipeline, quickly find abnormal points, make accurate judgment and positioning, effectively avoid the economic loss caused by disassembly, and at the same time improve service quality and enhance customer satisfaction.
