3. Thermal Imaging Mode
To activate thermal imaging:
- Select the "IR Camera" mode from the main menu.
- Point the camera lens towards the object or area you wish to inspect.
- The screen will display the thermal image with temperature readings.
- Adjust emissivity (0.1 – 0.99, default 0.95) as needed for accurate temperature measurements based on the material being inspected.
- Choose from various color palettes (e.g., White Heat, Black Heat, Rainbow, Iron Red) to visualize temperature differences effectively.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is discharged or incorrectly installed. | Charge the battery. Ensure the battery is inserted with correct polarity. |
| Thermal image is blurry or unclear. | Lens is dirty; incorrect focus (with macro lens); object is out of range. | Clean the lens. Adjust the macro lens position. Ensure the object is within the optimal working distance. |
| Multimeter readings are inaccurate. | Probes are not properly connected; incorrect measurement function selected; battery low. | Check probe connections. Select the correct measurement mode. Charge the battery. |
| Cannot connect to PC. | USB cable issue; driver not installed; device not in data transfer mode. | Try a different USB cable/port. Install necessary drivers (if prompted). Ensure the device is in USB mode. |
