4. Настройка

4.1 Распакаванне

Carefully remove all components from the packaging. Verify that all items listed in the 'Components' section are present and undamaged.

4.2 Зарадка акумулятара

The main unit and receiver have integrated rechargeable lithium batteries. Connect the device to a 5V/2A/10W power source or a Type-C charger using the provided USB cable. The charging indicator will show the charging status. Ensure both units are fully charged before first use for optimal battery life.

4.3 Уключэнне/выключэнне сілкавання

Press and hold the power button on the main unit to turn it on or off. The device will display the main menu upon startup.

5. Інструкцыя па эксплуатацыі

5.1 Агульная навігацыя

The device features a 3.2-inch HD screen for clear display of functions and results. Use the navigation buttons (up, down, left, right, OK) to select and confirm options in the menu. The main screen provides access to various testing modes.

5.2 Cable Length Measurement

This function measures the length of network cables. Connect one end of the cable to the main unit and the other end to the remote unit or leave it open, depending on the cable type and measurement method. Select 'Cable Length' from the menu and follow the on-screen prompts for calibration and measurement.

5.3 Cable Wiremap Testing

The wiremap function checks the continuity and correct wiring configuration of network cables (RJ45). Connect the cable to both the main unit and the receiver. The screen will display the wiring status, indicating any short circuits, open circuits, or cross-overs.

5.4 Wire Tracing (Scan)

Use the wire tracing function to locate specific cables within a bundle. Connect the main unit to the cable to be traced. The receiver unit can then be used to detect the signal emitted by the main unit, helping to identify the target cable.

5.5 PoE Testing

The PoE (Power over Ethernet) test function measures the voltage and power supplied by PoE switches or injectors. Connect the device to a PoE-enabled port. The screen will display the PoE voltage and pin configuration providing power.

5.8 Вымяральнік аптычнай магутнасці (OPM)

The OPM measures the power of optical signals in fiber optic cables. Connect the fiber optic cable to the OPM port. Select the appropriate wavelength and the device will display the optical power reading.

5.9 Crimping QC Test

This function tests the quality of crimped crystal connectors (RJ45). Insert the crimped connector into the designated port. The device will analyze the connection and indicate if the crimp is correct or if there are issues with individual wires.

5.10 Remote ID Testing

Use the remote ID test cables to identify multiple network cables simultaneously. Connect the main unit to one end of the cables and the remote ID units to the other ends. The device will display the corresponding ID for each cable.

6. Тэхнічнае абслугоўванне

6.1 Ачыстка

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the ports and connectors free from dust and debris.

6.2 Захоўванне

Захоўвайце прыладу ў прахалодным, сухім месцы, удалечыні ад прамых сонечных прамянёў і экстрэмальных тэмператур. Пры працяглым захоўванні пераканайцеся, што акумулятар часткова зараджаны (каля 50%), каб падоўжыць тэрмін яго службы.

6.3 Сыход за акумулятарам

Recharge the battery regularly, even if the device is not in frequent use. Avoid fully discharging the battery repeatedly, as this can reduce its overall capacity.

7. Выпраўленне непаладак

• Прылада не ўключаецца: Пераканайцеся, што акумулятар зараджаны. Падключыце да крыніцы харчавання і паспрабуйце яшчэ раз.
• Inaccurate cable length readings: Ensure proper calibration. Check for damaged cables or connectors. Verify the correct cable type setting if applicable.
• Wiremap errors: Check for proper connection of both main and receiver units. Inspect the cable for physical damage or incorrect crimping.
• Няма выяўлення PoE: Ensure the connected device is a PoE source and is active. Check the cable connection.
• VFL not working: Ensure the fiber optic cable is properly connected and clean. Check if the VFL function is enabled.
