3. Product Overview and Components
The TOOLTOP ET14C Thermal Camera is designed for portability and ease of use. Familiarize yourself with the main components:
- Thermal Imager: Main unit with 2.8-inch display.
- Macro Lens: Optional accessory for detailed close-up thermal imaging.
- Detachable 18650 Lithium-ion Battery: Provides power to the device.
- USB Type-C Cable: For charging and data transfer.
- Storage Bag: For protecting and transporting the device.
4. Setup
4.1 Battery Installation and Charging
- Locate the battery compartment on the rear of the device.
- Insert the provided 18650 Lithium-ion battery, ensuring correct polarity.
- Close the battery compartment cover securely.
- Connect the USB Type-C cable to the camera's Type-C port and the other end to a suitable USB power adapter (not included) or computer for charging. The device supports up to 8 hours of continuous use on a full charge.
4.2 Macro Lens Attachment (Optional)
If your model includes the optional macro lens, it does not require installation. Simply move the macro lens left or right during use to engage or disengage it. The optimal working distance for the macro lens is approximately 2.5cm. For distances exceeding this, use the normal thermal imaging mode to avoid blurred images.
5. Operating Instructions
5.1 Power On/Off
Press and hold the power button (location typically on the side or top) to turn the device on or off. The 2.8-inch display will illuminate.
5.2 Display Interface and Navigation
The 2.8-inch display (240x320 resolution) shows real-time thermal images and measurement data. Use the navigation buttons (MEMU, MARK, REMOVE, HOLD, SAVE) to interact with the interface.
5.3 Thermal Imaging Parameters
- Image Capture Frequency: 25Hz, providing smooth real-time thermal video.
- Thermal Imaging Pixels: ISR 240x240, for clear and detailed thermal resolution.
- Field of View (FOV): 50.0°(H) × 50°(V) / 72.1°(D).
- Temperature Range: -20℃ to +550℃ (-4℉ to 1022℉).
- Accuracy: ±2℃ or ±2% (whichever is greater).
- Measurement Resolution: 0.1℃ / 0.1℉.
- Gain Mode: Auto Gain, automatically adjusts for optimal image quality.
5.4 Emissivity Adjustment
Emissivity can be adjusted from 0.1 to 0.99 (default is 0.95). Adjusting emissivity is crucial for accurate temperature measurements, as different materials emit infrared energy differently. Consult a material emissivity table for specific values.
5.5 Color Palette Selection
The camera offers several color palettes to visualize temperature differences:
- Iron Red
- Rainbow
- Fusion
- White Heat
- Red Heat
Select the palette that best highlights the temperature variations for your specific application.
5.6 Photo Taking and Viewing
The device supports taking and viewing photos. Images are stored in BMP format in the internal 7.5MB storage. Use the 'SAVE' button to capture an image and the 'MEMU' button to navigate to the image gallery for viewing.
5.7 PC Software Analysis
Connect the camera to a computer via the USB Type-C cable. In USB Mode, you can transfer and analyze thermal images using compatible PC software (software not included, typically available for download from the manufacturer's website).
5.8 Temperature Excess Alert
The device features a temperature excess alert system, which can be configured with a specific alarm threshold. When the measured temperature exceeds this threshold, the device can provide a light alarm and/or an audible alarm.
6. Maintenance
6.1 Cleaning the Device
Wipe the camera body with a soft, dry cloth. For the lens, use a lens cleaning cloth and solution specifically designed for optical lenses. Do not use abrasive cleaners or solvents.
6.2 Battery Care
The detachable 18650 Lithium-ion battery should be charged regularly. If storing the device for an extended period, ensure the battery is partially charged (around 50%) and remove it from the device to prevent deep discharge.
6.3 Storage and Operating Conditions
- Storage Temperature: -20℃ to 60℃ (-4℉ to 140℉).
- Operating Temperature: 0℃ to 50℃ (32℉ to 122℉).
- Operating Humidity: <85%RH (non-condensing).
Store the device in its provided storage bag in a cool, dry place when not in use.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is low or not installed correctly. | Charge the battery or ensure it is installed with correct polarity. |
| Image is blurred when using macro lens. | Object is outside the optimal working distance. | Ensure the object is approximately 2.5cm from the macro lens. For further distances, disengage the macro lens. |
| Cannot transfer images to PC. | Incorrect USB mode or faulty cable. | Ensure the camera is in USB Mode. Try a different USB cable or port. |
| Inaccurate temperature readings. | Incorrect emissivity setting. | Adjust the emissivity setting to match the material being measured. |
