5. Setup

5.1 Charging the Battery

The ET34C comes with a built-in 1500mAh rechargeable lithium battery. Before first use, or when the low battery indicator appears, connect the device to a power source using the provided USB charging cable. A 5V/2A/10W or higher power adapter is required (not included). The charging indicator will show the charging status.

5.2 Initial Power On

Press and hold the power button (usually located on the front panel) until the screen illuminates. The device will boot up and display the main thermal imaging interface.

5.3 Language Selection

Upon first use, or if you need to change the language, navigate to the 'Setup' menu. Use the navigation buttons to select 'Language' and choose your preferred language (Chinese, English, German, French, or Spanish).

6. Operation

6.1 Basic Thermal Imaging

Once powered on, the device will immediately display a live thermal image. Point the camera at the object or area you wish to inspect. The screen will show temperature readings and a thermal representation of the scene.

6.2 Macro Photography

For detailed inspection of small components (e.g., on circuit boards), attach the magnetic macro lens to the front of the thermal imager. The macro lens allows for clear viewing and temperature measurement of objects as small as 1mm. Ensure the lens is securely attached for accurate readings.

6.3 Color Palettes

The ET34C offers seven color palette modes to visualize temperature differences. These modes can be cycled through via the menu or a dedicated button (refer to the on-screen interface for specific controls). Available palettes include:

• Incandescence
• Green Heat
• Red Hot
• Lava
• Iron Oxide Red
• Black Hot
• Rainbow

6.4 Automatic Temperature Capture (3-Point Measurement)

The device automatically identifies and displays three key temperature points on the screen: the Center Point, the Highest Temperature Point (Max), and the Lowest Temperature Point (Min). This feature helps in quickly identifying hot spots and cold spots within the field of view.

6.5 Image Storage

To save a thermal image, press the 'OK' button. The device will typically save the current thermal image to its internal memory. The ET34C can store up to 60 data sets. Saved images can be reviewed in the 'Image Storage' menu.

6.6 System Settings

Access the 'Setup' menu to adjust various device settings:

• Language: Change the display language.
• Brightness: Adjust screen brightness (e.g., 25%, 50%, 75%, 100%).
• Auto Power Off: Set the idle time before the device automatically shuts down to conserve battery.
• Sound: Toggle device sounds on or off.
• LED Light: Control the built-in LED light (if applicable).
• Factory Reset: Reset all settings to their default values.

7. Maintenance

7.1 Cleaning the Device

Use a soft, dry cloth to clean the exterior of the thermal imager. For the screen and lens, use a microfiber cloth specifically designed for optics. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the device or its coatings.

7.2 Battery Care

To prolong battery life, avoid fully discharging the battery frequently. If storing the device for an extended period, ensure the battery is charged to approximately 50-70% and recharge it every few months. Store the device in a cool, dry place.

7.3 Storage

When not in use, store the ET34C in its provided storage bag to protect it from dust, moisture, and physical damage. Avoid storing it in extreme temperatures or direct sunlight.

8. Troubleshooting

8.1 Device Does Not Power On

• Ensure the battery is sufficiently charged. Connect the device to a power source and allow it to charge for at least 30 minutes before attempting to power on again.
• Verify that the power button is being pressed and held correctly.

8.2 Inaccurate Temperature Readings

• Check if the lens is clean and free from dust or smudges.
• Ensure the measurement distance is within the specified range (0.2~3m).
• Consider the ambient temperature and emissivity settings (if adjustable, though not explicitly mentioned in provided data, it's a common thermal camera feature).
• Perform a factory reset if issues persist, as this may resolve software-related calibration problems.

8.3 Screen Display Issues

• Adjust the screen brightness in the 'Setup' menu.
• If the screen is frozen or unresponsive, try restarting the device. If a restart doesn't work, allow the battery to fully discharge and then recharge it.

8.4 Cannot Save Images

• Check if the internal storage is full. The device can store up to 60 data sets. You may need to delete old images to free up space.
• Ensure the 'OK' button is pressed firmly and held for the required duration (e.g., 3 seconds for save).

9. User Tips

• For PCB Inspection: When working with small electronic components, always use the magnetic macro lens for enhanced detail and more precise temperature readings.
• Optimize Viewing: Experiment with different color palettes to find the one that best highlights the temperature differences relevant to your inspection task. For example, 'Rainbow' often provides a good general overview, while 'Black Hot' or 'White Hot' can be useful for specific contrast needs.
• Battery Conservation: Utilize the 'Auto Power Off' feature and adjust screen brightness to lower settings when possible to extend battery life during long inspection sessions.
• Stable Readings: For the most accurate temperature measurements, hold the camera steady and allow a few seconds for the thermal image to stabilize on the screen.
