Leakage Detection and Analysis
- One-key Quick Check: Use this function to quickly locate abnormal temperature points on the PCB. You can troubleshoot defects by adjusting the temperature range in the software.
- High Temperature Warning: If a component's temperature exceeds a preset threshold, the software will display a red flashing frame around the hot spot and emit an audible alert. Utilize the "High TEMP Tracing" function to automatically track and mark the highest temperature point on the entire image.
- 3D/2D Thermal Field Distribution: Access professional modes for in-depth product evaluation and thermal distribution analysis. This includes analyzing circuit board thermal structure design and heat dissipation efficiency.
- Comparative Analysis: Optimize thermal distribution designs by comparing defects between different boards, analyzing work differences, and recording regional temperature curves.
- Locating Subtle Leaks: In cases of weak current leakage or interference, if the leakage component cannot be directly located by the quick check function, adjust the image contrast by modifying the temperature range to precisely pinpoint the leakage component.

• Long-press the power button on the device until the LED indicator turns steady orange. - Software Not Detecting Device:
• Verify the Type-C connection. Try a different USB port or cable.
• Ensure the Qianli IR software is correctly installed and updated to the latest version.
• Try restarting the software and then the thermal camera.
• Check your computer's device manager to see if the device is recognized. - Unclear Thermal Images:
• Adjust the adjustable focus lens on the device to achieve a clear image.
• Ensure the measurement distance is within the recommended range (2mm to infinity, with lens height from desktop approximately 130mm).
• Check for any obstructions to the thermal or visible light lenses. - Inaccurate Temperature Readings:
• Ensure the device is being used within its specified working environment temperature and humidity ranges.
• If a significant discrepancy is suspected, refer to the software settings for any calibration options or contact support. - Difficulty Locating Subtle Leaks:
• Utilize the adjustable temperature range feature within the software to enhance the contrast of the thermal image, making subtle leakage points more visible.
User Tips
- Software Download: Always download the latest Qianli IR software directly from the official website: WWW.QIANLI.CN. This ensures compatibility and access to the newest features.
