4. Setup
4.1 Battery Installation and Charging
The ET14S is powered by a built-in rechargeable 18650 lithium battery. Before first use, ensure the battery is fully charged.
- Locate the battery compartment cover on the back of the device.
- Open the cover and insert the 18650 battery, ensuring correct polarity.
- Connect the provided USB data cable to the device's charging port and the other end to a standard USB power adapter (not included) or a computer USB port.
- The charging indicator on the screen will show the charging status. A full charge typically takes several hours and provides up to 8 hours of continuous use (measured at 30% screen brightness).
4.2 Initial Power On
To power on the device, press and hold the power button located on the side until the screen illuminates. The device will boot up and display the main interface, typically starting in multimeter mode.
5. Operating Instructions
5.1 General Operation
The ET14S features a 2.8-inch IPS high-definition full-view LCD screen for clear display of measurements and thermal images. Navigation is primarily done using the buttons below the screen.
5.2 Thermal Imaging Mode
The thermal imager features an ISR 240x240 resolution with a 25Hz image capture frequency, providing detailed thermal insights. The temperature range is -20℃ to +550℃.
- To switch to thermal imaging mode, press the dedicated IR/DMM button.
- The screen will display a thermal image, with temperature readings and a crosshair indicating the measurement point.
- Adjust emissivity settings if necessary for accurate temperature readings on different surfaces. Refer to the on-screen menu for this setting.
5.3 Multimeter Mode
The integrated multimeter is a 9999 counts True RMS device, capable of measuring AC/DC current, voltage, resistance, capacitance, frequency, and performing diode and continuity tests.
- To switch to multimeter mode, press the IR/DMM button.
- Connect the multimeter probes to the appropriate input jacks (VΩHz, COM, A).
- Use the function buttons (V, Ω, Hz/%, A) to select the desired measurement type. The device supports auto-ranging.
- For specific functions like AC/DC selection or relative measurement, use the AC/A and REL buttons.
5.4 Optional Macro Lens Usage
An optional macro lens can be attached to the device for inspecting small details, such as those on PCB boards. This enhances the thermal imaging capability for electronic research and repair.
- To install the macro lens, align it with the camera module on the back of the device and slide it into place.
- Ensure the lens is securely seated.
- When using the macro lens, small details of 1mm * 1mm can be clearly seen.
5.5 Wide Applications Range
The ET14S is suitable for a variety of applications due to its dual functionality:
- Power System Maintenance: Identify overheating components or faulty connections.
- Underfloor Heating Inspection: Locate heating elements and identify blockages or leaks.
- Automobile Maintenance: Diagnose electrical issues, check engine component temperatures.
- PCB Board Repair: Pinpoint hot spots on circuit boards for efficient troubleshooting.
6. Maintenance
6.1 Cleaning
To ensure the longevity and accuracy of your ET14S, follow these cleaning guidelines:
- Wipe the device's exterior with a soft, dry cloth.
- For stubborn dirt, a slightly damp cloth with mild soap can be used, followed by a dry cloth.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing or screen.
- Keep the thermal lens and multimeter input jacks free of dust and debris. Use a soft brush or compressed air if necessary.
6.2 Storage
When not in use, store the ET14S in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided instrument storage bag to protect it from dust and physical damage.
7. Troubleshooting
If you encounter issues with your ET14S, refer to the table below for common problems and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Low battery or battery not installed correctly. | Charge the battery or ensure it is correctly inserted with proper polarity. |
| Inaccurate temperature readings | Incorrect emissivity setting; lens dirty; object too far. | Adjust emissivity; clean the thermal lens; move closer to the object. |
| Multimeter readings are unstable or zero | Loose probe connection; incorrect function selected; circuit not powered. | Ensure probes are securely connected; select the correct measurement function; verify the circuit is live if measuring voltage/current. |
| Screen is dim or flickering | Low battery; display settings. | Charge the battery; check display brightness settings in the menu. |
