4. انتهى المنتجview
The NF-810 consists of two main units: the Emitter and the Receiver. Familiarize yourself with the components of each unit.
Figure 4.1: Labeled diagram of the NF-810 Emitter and Receiver units.
Emitter Unit
- منفذ RJ45: For connecting Ethernet cables.
- منفذ RJ11: لتوصيل خطوط الهاتف.
- قرص الوظيفة: Selects between CONT (Continuity), SCAN, OFF, TONE, and SHORT modes.
- Wiremap Indicators (1-8, G): LEDs to display wire status.
وحدة الاستقبال
- مسبار: For tracing cables and detecting signals.
- ضوء LED: يضيء مناطق العمل المظلمة.
- Power/SCAN Indicator: Shows power status and scan activity.
- مقبض الحساسية: Adjusts the sensitivity of the receiver.
- منفذ سماعة: For connecting headphones for clearer tone detection.
- زر LED: Activates the LED light.
- Wiremap Indicators (1-8, G): LEDs to display wire status (Mid-span, End-span).
- منفذ RJ45: For connecting Ethernet cables for wiremap testing.
5. الإعداد
5.1 تركيب البطارية
The NF-810 requires 1 Lithium Metal battery (9V laminated battery) for operation. Ensure the battery is installed correctly in both the Emitter and Receiver units.
- Locate the battery compartment cover on the back of each unit.
- افتح الغطاء عن طريق سحبه أو فكه.
- Insert the 9V battery, observing the correct polarity (+/-) markings.
- أغلق غطاء حجرة البطارية جيدًا.
6. تعليمات التشغيل
6.1 Cable Measurement (Wiremapping)
This function detects breaks, shorts, crossovers, and shielding issues in LAN (RJ45) and telephone (RJ11) cables.
- Connect one end of the cable to the RJ45 or RJ11 port on the Emitter unit.
- Connect the other end of the cable to the corresponding RJ45 port on the Receiver unit.
- Turn the Emitter's function dial to the 'CONT' position.
- Observe the wiremap indicators (LEDs 1-8 and G) on both the Emitter and Receiver.
- اتصال عادي: LEDs on both units will light up sequentially from 1 to 8, then G (for shielded cables).
- دائرة مفتوحة: If a specific LED does not light up, that wire is open.
- دائرة مقصورة: If two or more LEDs light up simultaneously, a short circuit exists between those wires.
- عبور: If the sequence of LEDs is incorrect (e.g., Emitter 1 lights up, but Receiver 2 lights up), a crossover is detected.
Figure 6.1: Performing a wiremap test with the NF-810.
6.2 Wire Tracing (Scanning/Tone Function)
This function helps locate and identify specific cables within a bundle or wall.
- Connect one end of the target cable to the RJ45 or RJ11 port on the Emitter unit. For non-RJ cables, use the alligator clip cable to connect to the wire pair.
- Turn the Emitter's function dial to the 'SCAN' or 'TONE' position. The Emitter will generate an audible tone.
- Turn on the Receiver unit and adjust the sensitivity knob to a suitable level.
- Use the Receiver's probe to scan the cables or wires you suspect are the target.
- The Receiver will emit a louder sound and/or the yellow-green signal indicator will illuminate more brightly when it detects the tone from the target cable.
Figure 6.2: Using the Receiver for wire tracing.
6.3 PoE Tester Function
The NF-810 can detect Power over Ethernet (PoE) presence, identify PoE switch types, and measure the number of PoE power supply cores.
- Connect the Ethernet cable from the PoE source (e.g., PoE switch) to the RJ45 port on the Receiver unit.
- The Receiver will automatically detect PoE presence.
- Observe the LEDs on the Receiver unit. They will indicate the PoE power supply cores (Mid-span or End-span) and potentially the voltage.
- حذر: The device is designed to withstand voltages up to 60V. Do not test circuits exceeding this voltagهـ- لمنع الضرر.
Figure 6.3: Testing PoE functionality.
6.4 Telephone Line Detection
This feature allows for detecting the polarity, on/off status, and standby status (idle, ringing, talk) of telephone lines.
- Connect the telephone line to the RJ11 port on the Emitter unit.
- Turn the Emitter's function dial to the 'TEL' position (if available, or use 'CONT' and interpret the LEDs).
- The LEDs will indicate the line status:
- الخمول: Specific LEDs will light up, indicating a normal standby line.
- رنين: LEDs may flash or change pattern during an incoming call.
- الحديث: LEDs will indicate the active talk state and polarity.

6.5 إضاءة LED
The Receiver unit is equipped with an LED light to assist in dark environments.
- Press the 'LED' button on the Receiver unit to turn the light on or off.

7. الصيانة
Proper maintenance ensures the longevity and accuracy of your NF-810 tester.
- تنظيف: امسح الجهاز بقطعة قماش ناعمة وجافة. لا تستخدم منظفات أو مذيبات كاشطة.
- تخزين: قم بتخزين الجهاز في مكان بارد وجاف، بعيدًا عن أشعة الشمس المباشرة ودرجات الحرارة القصوى.
- العناية بالبطارية: قم بإزالة البطاريات إذا لم يتم استخدام الجهاز لفترة طويلة لمنع التسرب.
- حماية التحقيق: Ensure the Receiver's probe is not bent or damaged during storage or transport.
8. استكشاف الأخطاء وإصلاحها
If you encounter issues with your NF-810, refer to the following common problems and solutions:
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| الجهاز لا يعمل. | بطارية ميتة أو تم تركيبها بشكل غير صحيح. | تحقق من قطبية البطارية؛ استبدلها ببطارية جديدة 9 فولت. |
| Inaccurate wiremap readings. | Poor cable connection; damaged cable; incorrect mode. | Ensure cables are fully inserted. Test with a known good cable. Verify Emitter is in 'CONT' mode. |
| No tone detected during scanning. | Emitter not in 'SCAN' or 'TONE' mode; Receiver sensitivity too low; dead battery in Emitter. | Set Emitter to 'SCAN' or 'TONE'. Increase Receiver sensitivity. Replace Emitter battery. |
| PoE test not working. | No PoE power on the line; voltagيتجاوز 60 فولت. | Verify PoE source is active. Do not test lines exceeding 60V. |
