3. Setup and Installation
- Check Compatibility: Ensure your iOS device has a Lightning Port and is an iPhone 7 or newer, or a compatible iPad model. This device is not compatible with iOS devices requiring a Type-C port or Mac computers.
- Download the App: Search for "TopInfrared" in the Apple App Store and download the application.
- Connect the Camera:
- Directly plug the TC002 thermal camera into your iOS device's Lightning Port.
- Alternatively, use the included 19.7-inch (50cm) adapter cable for more flexible positioning of the camera.
- Launch the App: Once connected, the "TopInfrared" app will automatically detect the device and prompt you to open it. Allow a few seconds for initial calibration.

4. Operating Instructions
The "TopInfrared" app provides a user-friendly interface for controlling the TC002 thermal camera and analyzing thermal data.
4.1 Measurement Modes
The app offers three primary measurement modes:
- Point: Displays the temperature at a specific point on the screen.
- Line: Shows temperature readings along a user-defined line.
- Surface: Identifies the highest and lowest temperatures within a selected area.
4.2 Image Customization and Analysis
- Color Palettes: Choose from 11 different color palettes to visualize temperature data according to your preference or application.
- Sharpness and Contrast: Adjust these settings within the app to optimize the clarity and detail of the thermal image.
- Picture-in-Picture (PIP) Mode: Combine the thermal image with a visible light image for enhanced context, particularly useful for identifying low-temperature items.
- Image Rotation: Rotate the image to view temperatures from different angles.
- Waveform Graph: Monitor continuous temperature changes over time using the waveform graph feature.
- Photo and Video Recording: Capture thermal images and record videos directly through the app for later review and analysis.
- Smart Alerts: Set custom temperature thresholds to receive alerts when temperatures exceed or fall below specified limits.

6. Maintenance and Care
- Cleaning: Use the provided cleaning cloth or a soft, dry cloth to gently wipe the camera lens and body. Avoid abrasive materials or harsh chemicals.
- Storage: When not in use, store the TC002 in its carrying bag to protect it from dust, moisture, and physical damage.
- Environmental Conditions: Avoid exposing the device to extreme temperatures, high humidity, or direct sunlight for prolonged periods.
- Shutter Mechanism: The camera features an internal shutter that may produce a clicking sound during operation. This is a normal function for calibration and maintaining accuracy. Users can manually close the shutter if desired, though this may affect calibration cycles.
7. Troubleshooting
- Device Not Detected:
- Ensure the TC002 is securely plugged into the Lightning Port of your iOS device.
- Verify that the "TopInfrared" app is installed and open.
- Check if your iOS device is compatible (iPhone 7 or above, iPad with Lightning Connector).
- Restart the "TopInfrared" app or your iOS device.
- Image Quality Issues:
- Adjust sharpness and contrast settings within the app.
- Ensure the camera lens is clean and free of smudges or dust.
- Verify TISR mode is enabled for enhanced resolution if desired.
- Clicking Sound During Operation: This is a normal function of the thermal camera's internal shutter, used for calibration to maintain measurement accuracy. It is not an indication of a malfunction.
- Inaccurate Temperature Readings:
- Allow the device a few minutes to stabilize and calibrate after startup.
- Ensure the camera is used within its specified operating temperature range.
- Check for any obstructions or dirt on the lens.
