5. Setup
5.1. Battery Installation and Charging
The TR20 Pro comes with a built-in Lithium Ion battery. Ensure the device is fully charged before first use.
- Connect the provided USB charging cable to the camera's charging port.
- Connect the other end of the USB cable to a compatible USB power adapter (not included) or a computer's USB port.
- The charging indicator on the device will show the charging status. A full charge typically takes several hours.
5.2. Powering On/Off
- To Power On: Press and hold the power button (usually marked with a red circle or power symbol) until the screen illuminates.
- To Power Off: Press and hold the power button until the shutdown prompt appears, then confirm or continue holding until the device powers down.
6. Operating Instructions
6.1. Understanding the Display and Navigation
The TR20 Pro features a 2.8-inch LCD with 480 x 640 resolution, displaying thermal images and critical data. The screen shows temperature readings, battery status, time, and selected imaging modes.
Navigate menus and settings using the directional buttons and the 'SET' button for confirmation. Refer to the on-screen prompts for specific menu options.
6.2. Dual-Lens Imaging and Multi-Mode View
The TR20 Pro offers five distinct image modes to suit various inspection needs:
- Infrared Only: Displays a pure thermal image.
- Visible Only: Displays a standard visual image from the optical camera.
- Blending: Overlays a semi-transparent thermal image onto the visible image.
- Fusion: Combines thermal and visible details for a clearer representation.
- Outline Enhancement: Highlights the edges of objects in the thermal image for better definition.
These modes allow users to easily match heat patterns with real-world visuals, enhancing inspection results.

6.3. Accurate Temperature Measurement
The device provides accurate temperature readings across a range of -20 to 550 °C, with an accuracy of ±2 °C. Its high sensitivity (NETD ≤ 40 mK) allows for the detection of small temperature differences, crucial for precise diagnostics. The 50° wide-angle lens ensures a broad field of view, capturing more area in a single image.
6.4. Selecting Thermal Palettes
The TR20 Pro offers eight selectable color palettes to visualize temperature contrasts. Each palette highlights different temperature ranges and gradients, allowing users to choose the most suitable display for their specific application and to better interpret thermal data.

6.5. Smart Alerts and Quick Capture
The camera features customizable temperature alarms with both sound and light warnings. These alerts help in quickly identifying abnormal heat spots that exceed predefined thresholds. The quick-capture function allows for instant recording of images or video, ensuring that important findings are documented without delay.
7. Data Management and Analysis
The TR20 Pro supports built-in video recording and includes 8GB of internal storage for capturing and saving thermal data.
For in-depth analysis, the device supports the MiLESEEY Analyzer PC software. This software simplifies data review, allows for detailed reporting, and provides tools for further examination of recorded thermal images and videos.
