3. התקנה

3.1 התקנת סוללה

The NF-308 requires two 9V batteries for operation. These are typically included with the product. To install or replace batteries:

1. Locate the battery compartment on the back of the Emitter and Receiver units.
2. פתח את מכסה הסוללה.
3. Insert the 9V batteries, ensuring correct polarity (+/-).
4. סגור היטב את מכסה הסוללה.

3.2 הפעלה ראשונית

Press the power button on the Emitter unit to turn on the device. The LCD screen will illuminate, displaying the main menu options.

4. הוראות הפעלה

The NF-308 offers multiple testing modes accessible via the main menu. Use the arrow buttons to navigate and the 'OK' or 'Scan' button to select.

4.1 WireMap Test (Cable Continuity)

This mode checks for open circuits, short circuits, cross circuits, and reverse connections in network, telephone, and coaxial cables.

1. Connect one end of the cable to the appropriate port (RJ45, RJ11, or BNC) on the Emitter.
2. Connect the other end of the cable to the Remote Adapter (for remote testing) or directly to the Emitter's corresponding port (for local testing).
3. Select 'WireMap' from the Emitter's menu.
4. Press the 'Scan' button to begin the test. The LCD will display the wiring status (e.g., 'Pass', 'Open', 'Short').

4.2 Pair & Length Test (Cable Length Measurement)

This mode measures the length of network cables and identifies the distance to a fault.

1. Connect one end of the cable to the 'MAIN' port on the Emitter.
2. Ensure the other end of the cable is open (not connected to anything).
3. Select 'Pair&Length' from the Emitter's menu.
4. Press the 'Scan' button. The LCD will display the length for each pair and the distance to any detected open or short circuit.

4.3 Coax/Tel Test

This mode is specifically for testing coaxial and telephone cables.

1. Connect the coaxial or telephone cable to the respective BNC or RJ11 port on the Emitter.
2. Connect the other end to the Remote Adapter or leave it open as required by the test.
3. Select 'Coax/Tel' from the Emitter's menu.
4. Press the 'Scan' button to perform the test.

4.4 פונקציית פלאש פורט

The Port Flash function helps locate a specific network cable connected to a switch or router by causing its corresponding port LED to flash.

1. Connect one end of the network cable to the 'PORT FLASH' port on the Emitter.
2. Connect the other end of the cable to a port on the active switch or router.
3. Select 'Port Flash' from the Emitter's menu.
4. The Emitter will send a signal, causing the LED on the connected switch/router port to flash, allowing for easy identification.

4.5 Wire Tracing (Using the Receiver)

The Receiver unit is used to trace cables and locate them within bundles or walls.

1. Connect the cable to be traced to the Emitter.
2. הפעל את יחידת המקלט.
3. Adjust the sensitivity on the Receiver as needed.
4. Move the Receiver's probe along the suspected path of the cable. The Receiver will emit an audible tone, which will be strongest when it is directly over the cable being traced.

4.6 DC כרךtagה מדידה

The NF-308 can measure DC voltage בטווח של 0.5V עד 60V.

1. Connect the test leads (if provided, or use appropriate connectors) to the voltage measurement points on the Emitter.
2. Connect the other ends of the test leads to the DC voltagהמקור.
3. בחר את הכרךtage measurement function from the Emitter's menu. The LCD will display the measured voltage.

5. תחזוקה

To ensure the longevity and accurate performance of your NOYAFA NF-308, follow these maintenance guidelines:

• ניקוי: השתמשו במטלית רכה ויבשה לניקוי המכשיר. אין להשתמש בחומרי ניקוי שוחקים או ממסים.
• אִחסוּן: יש לאחסן את המכשיר במקום קריר ויבש, הרחק מאור שמש ישיר וטמפרטורות קיצוניות.
• טיפול בסוללה: הסר את הסוללות אם המכשיר לא ישמש למשך תקופה ממושכת כדי למנוע דליפות.
• טיפול: הימנע מלהפיל את המכשיר או לחשוף אותו למכות חזקות.

6. פתרון תקלות

אם נתקלת בבעיות עם ה-NF-308 שלך, עיין בבעיות הנפוצות ובפתרונות הבאים:

• המכשיר לא נדלק: בדוק את התקנת הסוללה וודא שהסוללות טעונות מספיק. החלף במידת הצורך.
• Inaccurate length measurement: Ensure the cable is properly connected and the remote adapter is not used for length measurement. Calibrate the device if needed (refer to the full manual for calibration steps).
• No signal from Receiver during tracing: Ensure the Emitter is powered on and sending a signal. Adjust the Receiver's sensitivity. Check for excessive interference in the environment.
• Cable test results are inconsistent: Verify cable connections are secure. Inspect cables for visible damage. Ensure the correct test mode is selected for the cable type.
