NT-0401 Cable Tester User Manual

1. Einleitung

The Lanberg NT-0401 is a versatile cable tester designed for verifying the integrity of various network and telephone cables. It supports RJ-45, RJ-12, and RJ-11 connectors, and is compatible with UTP, FTP, and SFTP cable types. Equipped with 9 LED indicators, it provides clear and immediate feedback on cable continuity, open circuits, short circuits, and crossed wires, making it an essential tool for network installation and maintenance.

2. Sicherheitshinweise

Please read and understand all safety instructions before operating the device. Failure to do so may result in injury or damage to the device.

• Setzen Sie das Gerät keiner Feuchtigkeit oder extremen Temperaturen aus.
• Versuchen Sie nicht, das Gerät zu öffnen oder zu verändern. Es enthält keine vom Benutzer austauschbaren Teile.
• Use only the specified battery type (AAAA) and ensure correct polarity during installation.
• Halten Sie das Gerät von starken elektromagnetischen Feldern fern.
• Disconnect the device from cables when not in use.

3. Produktüberschreitungview

The NT-0401 cable tester consists of two main components: the Main Unit and the Remote Unit. Both units feature LED indicators for pin-to-pin testing.

3.1. Hauptgerät

• RJ-45-Port: For testing Ethernet cables (Cat5, Cat5e, Cat6, etc.).
• RJ-12/RJ-11 Port: For testing telephone cables.
• BNC-Anschluss: For testing coaxial cables.
• LED-Anzeigen (1-8, G): Den Status jedes Aderpaares und der Erdung anzeigen.
• Power Switch (ON/OFF/S): Controls the device power and test speed. 'S' typically stands for 'Slow' test mode.

3.2. Remote Unit

• RJ-45-Port: Connects to the far end of the cable being tested.
• LED-Anzeigen (1-8, G): Mirror the main unit's indicators to confirm continuity.

4. Einrichtung

4.1. Einlegen der Batterie

1. Locate the battery compartment on the back of the Main Unit.
2. Schieben Sie die Batterieabdeckung auf.
3. Insert one (1) AAAA battery, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Schließen Sie die Batterieabdeckung fest.

4.2. Verbindungskabel

Before testing, ensure the cable is disconnected from any active network devices or power sources.

1. Connect one end of the cable to the appropriate port (RJ-45, RJ-12/RJ-11, or BNC) on the Main Unit.
2. Connect the other end of the cable to the corresponding port on the Remote Unit. For short cables, the remote unit can remain attached to the main unit. For longer, installed cables, detach the remote unit.

5. Bedienungsanleitung

5.1. Performing a Cable Test

1. Ensure the cable is properly connected to both the Main and Remote Units.
2. Slide the power switch on the Main Unit to the "ON" position for a normal test speed, or to "S" for a slower test speed (useful for visual inspection of individual wire status).
3. Observe the LED indicators on both the Main and Remote Units.
4. After the test sequence completes, slide the power switch to "OFF" to conserve battery life.

5.2. Interpretation von LED-Anzeigen

The LEDs illuminate sequentially, indicating the status of each wire pair (1-8) and the ground (G) connection.

• Normal Connection: LEDs on both the Main and Remote Units illuminate in the same sequence (e.g., 1-2-3-4-5-6-7-8-G).
• Open Circuit (Broken Wire): If a specific LED on the Main Unit illuminates but its corresponding LED on the Remote Unit does not, it indicates an open circuit (broken wire) for that particular pin.
• Kurzschluss: If two or more LEDs illuminate simultaneously on either unit, or if LEDs fail to illuminate for certain pins while others do, it indicates a short circuit between those wires.
• Crossed Wires: If the sequence of illuminated LEDs on the Remote Unit does not match the sequence on the Main Unit (e.g., Main shows 1-2-3, Remote shows 1-3-2), it indicates crossed wires.
• Keine Lichter: If no LEDs illuminate, check battery, cable connection, or if the cable is severely damaged.

6. Wartung

6.1. Reinigung

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the ports or battery compartment.

6.2. Speicherung

Bewahren Sie das Gerät an einem kühlen, trockenen Ort, geschützt vor direkter Sonneneinstrahlung und extremen Temperaturen, auf. Bei längerer Lagerung sollte der Akku entfernt werden, um ein Auslaufen zu verhindern.
