3. الإعداد والتشغيل الأساسي

3.1 شحن الجهاز

Connect the main unit and receiver to a power source using the provided USB charging cable. The battery indicator on the screen will show charging status. Ensure both units are fully charged before initial use for optimal performance.

3.2 تشغيل/إيقاف التشغيل

Press and hold the power button on the main unit to turn it on or off. The receiver unit typically powers on when the rotary switch is moved from the 'Off' position.

3.3 إعدادات اللغة

Navigate to the 'Set' menu on the main unit's screen using the navigation buttons. Select 'Language' to choose your preferred language (e.g., English).

4. تعليمات التشغيل

4.1 Cable Continuity Test

This function verifies the integrity and connectivity of network cables, identifying breaks, open circuits, short circuits, or crossovers.

1. Connect one end of the network cable to the RJ45 port on the main unit.
2. Connect the other end of the cable to the RJ45 port on the receiver unit.
3. Select 'Cont' (Continuity) from the main unit's menu.
4. The screen will display the wiring sequence and any detected faults (e.g., Short Circuit, Cable Open, Cable Cross).

4.2 قياس طول الكابل

This function measures the length of a connected cable using Time Domain Reflectometry (TDR) technology.

1. Connect one end of the cable to the RJ45 port on the main unit. The other end should be disconnected.
2. Select 'Length' from the main unit's menu.
3. The device will display the cable length. The measurement range is typically 2.5m to 200m.

4.3 Digital/Analog Cable Scan (Hunting)

This feature helps locate specific cables among a bundle, offering both digital and analog modes for different environments.

1. Connect one end of the target cable to the main unit.
2. Select 'Scan' from the main unit's menu and choose either 'Digital Mode' or 'Analog Mode'.
3. Use the receiver unit to trace the cable. The receiver will emit an audible tone when it detects the signal from the main unit.
4. Digital Mode is suitable for anti-jamming and high sensitivity in noisy environments. Analog Mode is for quick cable location.

4.4 PoE Test

The PoE test identifies Power over Ethernet devices and their power supply characteristics.

1. Connect the network cable from the PoE source (e.g., PoE switch) to the RJ45 port on the main unit.
2. Select 'PoE' from the main unit's menu.
3. The device will display information such as PoE standard (e.g., IEEE 802.3AF, IEEE 802.3AT), voltage, and power supply method (end-span/mid-span/8-core).

4.5 Ping Test & IP Scan

These functions help diagnose network connectivity and identify IP addresses within a network.

1. Connect the main unit to the network via its RJ45 port.
2. اختبار بينغ: Select 'Ping' from the menu. You can enter a destination IP address to test connectivity and measure round-trip times, indicating network traffic load and response speeds.
3. مسح IP: Select 'IP Scan' from the menu. The device will scan the network to discover active IP addresses. You can set a range for the IP scan.

4.6 Port Flashing & Network Rate Test

These features help identify connected ports and assess network speed.

1. Connect the main unit to a network port.
2. وميض المنفذ: Select 'Port Flash' from the menu. The indicator lights on the connected switch port will blink, allowing for quick identification of the physical port.
3. Network Rate Test: Select 'Speed' or 'Network Rate Test' from the menu. The device will display the operating rate (e.g., 10/100/1000Mbps) and duplex mode (Full/Half Duplex) of the connected port.

5. الصيانة

• تنظيف: استخدم قطعة قماش ناعمة وجافة لتنظيف الجهاز. لا تستخدم منظفات أو مذيبات كاشطة.
• تخزين: قم بتخزين الجهاز في مكان بارد وجاف بعيدًا عن أشعة الشمس المباشرة ودرجات الحرارة القصوى.
• العناية بالبطارية: Recharge the device regularly, even if not in use, to maintain battery health. Avoid fully discharging the battery for extended periods.
• حماية المنفذ: Always use the provided caps or covers for the RJ45/RJ11 ports when not in use to prevent dust and damage.

6. استكشاف الأخطاء وإصلاحها

• الجهاز لا يعمل: Ensure the battery is charged. Connect to a power source using the USB cable and try again.
• Inaccurate cable length measurement: Ensure the cable is disconnected from all other devices at the far end. Verify the cable type settings if applicable.
• No signal during cable scan: Check that the cable is properly connected to the main unit. Ensure the receiver is in the correct scan mode (Digital/Analog) and its sensitivity is adjusted.
• PoE test not detecting power: Verify that the connected port is indeed a PoE-enabled port and that the PoE source is active.
• الشاشة لا تستجيب: حاول إعادة تشغيل الجهاز. إذا استمرت المشكلة، تواصل مع خدمة العملاء.
