4. セットアップ

4.1 バッテリーの取り付け

The KELUSHI NF468 requires a 9V laminated battery for operation.

1. Separate the Master and Remote units if they are connected.
2. Locate the battery compartment cover on the back of the Master unit.
3. カバーをスライドさせるかクリップを外してコンパートメントを開きます。
4. Insert a 9V laminated battery, ensuring correct polarity (+/-).
5. 電池収納部のカバーをしっかりと取り付けてください。

5. 操作手順

Follow these steps to test your RJ45 or RJ11 cables:

1. Prepare the Tester: Ensure a 9V battery is installed in the Master unit.
2. ケーブルを接続します。
   • For RJ45 cables: Plug one end of the cable into the RJ45 port on the Master unit and the other end into the RJ45 port on the Remote unit.
   • For RJ11 cables: Plug one end of the cable into the RJ11 port on the Master unit and the other end into the RJ11 port on the Remote unit.
3. 電源オン: Slide the OFF/ON/S switch on the Master unit to the "ON" position for normal test speed, or to the "S" position for slow test speed. The Power LED will illuminate.
4. LEDインジケーターを観察します。 The LEDs (1-8, G) on both the Master and Remote units will light up sequentially, indicating the status of each wire pair.
5. 結果を解釈する:
   • 連続： If the cable is good, the LEDs on both units will light up in the same sequence (1-2-3-4-5-6-7-8-G).
   • 開回路: If a wire is broken, the corresponding LED on the Remote unit will not light up.
   • 短絡： If two or more wires are shorted, multiple LEDs will light up simultaneously or in an incorrect sequence.
   • 交差したワイヤー: If wires are crossed, the LEDs on the Remote unit will light up in a different sequence than the Master unit. For example, if Master shows 1-2-3 and Remote shows 1-3-2, wires 2 and 3 are crossed.
6. 電源を切る： After testing, slide the switch to the "OFF" position to conserve battery life.

7。 トラブルシューティング

If you encounter issues while using the KELUSHI NF468, refer to the following troubleshooting tips:

• No Power/LEDs not lighting up:
  • 9V電池が正しく取り付けられ、十分に充電されているか確認してください。必要に応じて電池を交換してください。
  • Ensure the OFF/ON/S switch is in the "ON" or "S" position.
• Inconsistent or incorrect LED readings:
  • Verify that the cable connectors are fully and securely inserted into the correct RJ45 or RJ11 ports on both the Master and Remote units.
  • Inspect the cable connectors for any bent pins or damage.
  • Test with a known good cable to confirm the tester is functioning correctly.
• Remote unit not responding:
  • Ensure the cable connecting the Master and Remote units is not excessively long or damaged, which could lead to signal degradation.
  • Confirm the Remote unit is properly connected to the cable.

8. メンテナンス

Proper maintenance will extend the lifespan of your KELUSHI NF468 Network Cable Tester:

• クリーニング： デバイスの外装を​​清掃する際は、柔らかく乾いた布をご使用ください。研磨剤入りの洗剤や溶剤は使用しないでください。
