4. Operating Instructions

The NF-859GT offers a wide range of testing capabilities. Below are instructions for common functions:

4.1 Cable Continuity Test (CONT)

This function verifies the integrity of network and telephone cables, identifying open circuits, short circuits, and cross-connections.

1. Connect one end of the cable to the RJ45/RJ11 port on the Main Tester Unit.
2. Connect the other end of the cable to the corresponding port on the Receiver Unit.
3. Select 'CONT' from the main menu on the Main Tester Unit.
4. The screen will display the wiring status, indicating if the cable is good, has a cross, short circuit, or open circuit.

4.2 Wire Tracing (Scan Mode)

Use this function to locate specific cables within a bundle or wall.

1. Connect the cable to be traced to the 'SCAN' port on the Main Tester Unit.
2. Select 'Scan' from the main menu. You can choose between Digital Mode and Analog Mode.
3. Use the Receiver Unit to trace the cable. The Receiver will emit an audible tone and display signal strength as it gets closer to the target cable.

4.3 Port Flashing

This feature helps identify the corresponding port on a network switch or hub.

1. Connect the Main Tester Unit to a network port on the switch/hub.
2. Select 'Port Flash' from the main menu.
3. The indicator light on the connected port on the switch/hub will flash, allowing for easy identification. The tester also displays port information like operating speed and duplex mode.

4.4 Cable Length Measurement

Measure the length of network cables.

1. Connect one end of the cable to the RJ45 port on the Main Tester Unit.
2. Select 'Length' from the main menu.
3. The device will display the cable length in meters or feet. The measurement range is 2.5m to 200m (8.2ft to 656ft).

4.5 POE Testing

Tests Power over Ethernet (PoE) devices and power supply.

1. Connect the Main Tester Unit to a PoE port or device.
2. Select 'POE' from the main menu.
3. The screen will display PoE information, including voltage, power supply type (End-span/Mid-span), and compliance with 802.3af/at standards.

4.6 QC Test (Crimping Test)

Checks the quality of RJ45 crimps.

1. Connect the crimped RJ45 connector to the 'QC TEST' port.
2. Select 'QC TEST' from the main menu.
3. The device will indicate if the crimp is good or if there are issues with specific pins.

4.7 Optical Power Meter (OPM)

Measures the power of optical signals.
