4. Operating Instructions

4.1 Network Cable Testing (TDR Technology)

The NF-859GK utilizes Time Domain Reflectometer (TDR) technology for accurate network cable testing. It supports RJ11, RJ45, CAT5, CAT5e, CAT6, and CAT6a cables (UTP/STP).

Figure 4: TDR Network Cable Testing Capabilities

This image illustrates the core functionalities of the NF-859GK, including TDR (Time Domain Reflectometer) technology for network cable testing, IP address testing, and VFL (Visual Fault Locator) with a double-ended red light pen. It confirms compatibility with CAT5/5e, CAT6/6a, CAT3, RJ45, and RJ11 cables.

4.1.1 Continuity Test (QC Function)

This function checks the wiring sequence and continuity of RJ11 and RJ45 network cables. It identifies open circuits, short circuits, and cross-connections.

1. Connect one end of the cable to the RJ45/RJ11 port on the main unit and the other end to the corresponding port on the receiver.
2. Select the 'Cont' (Continuity) option from the main menu.
3. The screen will display the wiring status (Good, Cross, Short Circuit, Open) for each wire pair.

Figure 5: QC Function & Continuity Testing

This image demonstrates the QC (Quality Control) function and continuity testing for RJ11 and RJ45 network cables (Cat5/5e/6/6a UTP/STP). It shows how the device indicates correct crimping via a digital light display and provides a clear pass/fail status for each wire, including telephone line-to-line testing and single-head crimp RJ45 plug tests.

4.1.2 Cable Length Measurement

The NF-859GK can accurately measure cable length within a range of 2.5m to 200m (8.2ft to 656ft).

1. Connect the cable to be measured to the main unit's RJ45/RJ11 port. The receiver is not required for this test.
2. Select the 'Length' option from the main menu.
3. The device will display the measured length in meters or feet.

4.2 IP Tester / PING Function

This tool diagnoses and maintains local area networks running TCP/IP protocol. It authenticates connections, checks data integrity, measures round-trip time, and provides IP addresses.

1. Connect the device to the network via an RJ45 cable.
2. Select 'IP Scan' or 'PING' from the menu.
3. Follow the on-screen prompts to initiate an IP scan or PING test. The device will display network information such as IP addresses, gateway, and ping statistics.

4.3 POE Tester

The POE (Power over Ethernet) tester efficiently identifies PoE devices, detects crossover modes (unknown/end-span/mid-span/8-core power supply), and polarity. It supports IEEE 802.3AF/IEEE 802.3AT standards and automatically switches between 10M/100M/1000M modes.

1. Connect the network cable from the PoE source to the RJ45 port on the main unit.
2. Select the 'POE' option from the main menu.
3. The device will display PoE voltage, pinout, and standard compliance (802.3af/at).

1. Connect the main unit to a network port using an RJ45 cable.
2. Select 'Port Flash' from the menu.
3. Observe the blinking indicator light on the network device to identify the connected port.

4.5 Visual Fault Locator (VFL)

The NF-859GK features a dual-head VFL function, acting as a 10mw visual fault locator for fast fiber finding. It supports universal joint FC/SC/ST interfaces and has a power detecting range of -70dBm to +10dBm.

1. Connect the fiber optic cable to the VFL port on the receiver.
2. Activate the VFL function.
