2. Sikkerhedsoplysninger
Overhold altid følgende sikkerhedsforanstaltninger for at forhindre personskade og skade på enheden:
- Forsøg ikke at reparere eller ændre enheden. Overlad al service til kvalificeret personale.
- Do not operate the device in explosive atmospheres or in the presence of flammable gases or fumes.
- Ensure proper polarity when connecting test leads to avoid damage to the device or the circuit under test.
- Afbryd altid strømmen til kredsløbet, før du foretager modstands-, kapacitans- eller diodemålinger.
- Vær forsigtig, når du arbejder med voltagover 30V AC RMS, 42V peak eller 60V DC, da disse udgør en risiko for stød.
- Hold enheden tør. Udsæt den ikke for regn eller fugt.
- Rengør kun enheden med en tør, blød klud. Brug ikke slibende rengøringsmidler eller opløsningsmidler.

4. Opsætning
4.1 Batteriinstallation og opladning
The ET14S is powered by a built-in rechargeable 18650 lithium battery. Before first use, ensure the battery is fully charged.
- Find batteridækslet på bagsiden af enheden.
- 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 Indledende tænding
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. Betjeningsvejledning
5.1 Generel drift
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 Termografisk tilstand
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 Multimetertilstand
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: Identificer overophedede komponenter eller defekte forbindelser.
- 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. Vedligeholdelse
6.1 Rengøring
To ensure the longevity and accuracy of your ET14S, follow these cleaning guidelines:
- Wipe the device's exterior with a soft, dry cloth.
