5.2.7 Color Palette
The APP offers 6 display modes for the color palette, allowing you to visualize thermal data in different ways.
- **Iron**: Red indicates maximum temperature, yellow for medium, and blue/black for low temperatures. Suitable for scenarios with distinct temperature differences.
- **White hot**: High-temperature areas are white, transitioning to black. Ideal for traditional black-and-white thermal imaging.
- **Black hot**: High-temperature areas are black, transitioning to white. Another option for traditional black-and-white thermal imaging.
- **Rainbow**: Uses a spectrum of colors (red, yellow, blue, black) to represent temperature ranges, suitable for general high and low temperature visualization.
- **Red heat**: Main colors are red and black, with a transition from black to white to red from minimum to maximum temperature. Focuses on high-temperature states.
- **Cold blue**: Blue marks colder regions, useful for observing low-temperature targets.
Adjusting the color palette bar on the right side of the screen allows you to modify the temperature range displayed, making specific regions more prominent.
5.2.8 Regional Temperature Measurement
Click the [Regional Temperature Measurement] button (labeled '10' in Figure 6) to add points, lines, or rectangular boxes for temperature measurement. Lines and rectangular boxes will display real-time maximum and minimum temperatures within their regions. Long-press a region to adjust its size and position, or click the trash icon to delete it.
5.2.9 Temperature Tracking
Click the temperature tracking button (labeled '11' in Figure 6) to enable or disable the measurement of maximum, minimum, and center point temperatures on the screen. Red indicates the maximum temperature, blue the minimum, and yellow the center point. Click once to turn on, and again to turn off.

This function highlights the current temperature within all rectangular boxes. If no rectangular box exists, one will be automatically added in the default position. Long-press a rectangular box to adjust its size and position. Click the delete icon next to it to remove the box.
5.2.11 High Temperature Alarm
Click the switch icon for [High Temperature Alarm] (labeled '13' in Figure 6) to set a high temperature alarm threshold. If the maximum temperature on the screen (or within a measured region, excluding point measurements) exceeds this threshold, the system will sound an alarm and the video screen will flash red.
5.2.12 Highlight High-temperature Regions
In this mode (labeled '14' in Figure 6), high-temperature regions are displayed using the current color palette, while other regions appear as white hot. The temperature range can be adjusted using the slider on the right side of the color board bar. This mode is useful for applications focusing specifically on high-temperature values.
6. Maintenance
6.1 Precautions for Use and Maintenance
- Do not use alcohol, detergent, or other organic cleaners to clean the lens, as this will damage the lens coating.
- Avoid directing sunlight, laser, or other strong light sources directly onto the lens. This can cause irreparable physical damage to the thermal imager.
- Ensure the OTG (On-The-Go) feature is enabled in your mobile phone settings for the APP to function correctly. Search for "OTG" in your phone's settings; some phones enable it by default.
7. Troubleshooting
If you encounter issues with your thermal imager, please refer to the following common troubleshooting steps:
- **Device not recognized**: Ensure OTG is enabled in your phone settings. Try restarting the phone and reconnecting the imager.
- **App not displaying thermal image**: Check if the imager is securely connected to the Type-C port. Verify that the APP has necessary permissions (e.g., camera access).
- **Inaccurate temperature readings**: Calibrate the emissivity and humidity settings in the APP according to the material being measured and the environment. Refer to the "Table of Reflectivity of Common Materials" in the Appendix.
- **App crashes or freezes**: Try restarting the APP. If the issue persists, clear the APP's cache or reinstall it.
8. User Tips
- For best results, ensure the lens is clean and free from dust or smudges before use.
- Experiment with different color palettes to find the most effective visualization for your specific application (e.g., "Red heat" for hot spots, "Cold blue" for cold spots).
- Utilize the regional temperature measurement and high-temperature alarm features for precise monitoring and early detection of anomalies.
- Keep the APP updated to the latest version to benefit from new features and performance improvements.
