يثبت
1. تركيب البطارية
The NF-468S requires a 9V battery for operation. To install:
- حدد موقع غطاء حجرة البطارية في الجزء الخلفي من الوحدة الرئيسية.
- قم بسحب الغطاء أو فكه لفتحه.
- قم بتوصيل بطارية 9 فولت بمشبك البطارية، مع مراعاة القطبية.
- ضع البطارية في الحجرة وأغلق الغطاء بشكل آمن.
A low battery indicator will illuminate when the battery needs replacement.
2. كابلات التوصيل للاختبار
Before testing, ensure the cable is disconnected from all active network devices.
- For network cables (RJ45): Connect one end of the cable to the RJ45 port on the main unit and the other end to the RJ45 port on the remote unit.
- For telephone lines (RJ11/RJ12): Connect one end of the cable to the RJ11 port on the main unit and the other end to the RJ11 port on the remote unit.
- For testing wall-mounted LAN cables or patch panels: Connect the main unit to the wall jack/patch panel and the remote unit to the other end of the cable run.
تعليمات التشغيل
1. Basic Cable Continuity Test (TEST Mode)
This mode checks for opens, shorts, and miswires in network and telephone cables.
- Connect the cable to be tested between the main unit and the remote unit as described in the Setup section.
- Slide the power switch to the "TEST" position.
- راقب مؤشرات LED (1-8، G) على كل من الوحدة الرئيسية والوحدة البعيدة.
- The LEDs will light up sequentially from 1 to 8, then G (Ground).
- تفسير النتائج:
- اتصال عادي: All LEDs (1-8, G) on both units light up in sequence, indicating a correct wiring scheme.
- دائرة مفتوحة: If a specific LED on either the main or remote unit does not light up, it indicates an open circuit (broken wire) for that particular conductor.
- دائرة مقصورة: If two or more LEDs light up simultaneously, it indicates a short circuit between those conductors.
- أسلاك متقاطعة: If the sequence of lighting is different between the main and remote units (e.g., main unit shows 1-2-3, remote shows 1-3-2), it indicates crossed wires.
- أزواج الانقسام: This can be harder to detect with simple LED testers. If all LEDs light up correctly but network performance is poor, a split pair might be present. Advanced testers are usually required for definitive split pair detection.

2. QC Function (RJ45 Connector Crimping Test)
This function helps verify the quality of RJ45 connector crimps.
- Connect the RJ45 cable to the main unit's RJ45 port. The remote unit is not needed for this test.
- Slide the power switch to the "QC" position.
- Press the RJ45 connector firmly into the port. The tester will analyze the connection.
- تفسير النتائج:
- Connected Well: All 1-8 lights on the main unit illuminate, indicating a proper crimp.
- اتصال ضعيف: If some lights (e.g., 2-4) are off, it indicates that the corresponding wire cores are not crimped properly.

3. PoE Test
The NF-468S can identify Power over Ethernet (PoE) devices and detect PoE standards.
- Connect the network cable from the PoE source (e.g., PoE switch) to the "PoE" port on the main unit. The remote unit is not required.
- Slide the power switch to the "TEST" position.
- Observe the PoE result indicators (D1-D4) and the PoE power supply type indicators.
- تفسير النتائج:
- The indicators will show if PoE is present and identify the power supply method (e.g., End-span (1/2, 3/6), Mid-span (4/5, 7/8), or 8-core power supply).
- It also indicates compliance with IEEE 802.3AF or IEEE 802.3AT standards, or if it's a non-standard PoE.

4. Cable Length Test (Approximate)
The NF-468S can provide an approximate cable length measurement for telephone lines up to 2000 meters.
- Connect one end of the telephone line (RJ11/RJ12) to the main unit's RJ11 port. The remote unit is not needed.
- Slide the power switch to the "TEST" position.
- The tester will display an approximate length. Note that this is an estimation and may vary based on cable quality and type.

صيانة
- تنظيف: Use a soft, dry cloth to clean the exterior of the tester. Do not use abrasive cleaners or solvents.
- تخزين: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
- استبدال البطارية: Replace the 9V battery when the low battery indicator illuminates to ensure accurate readings.
