5. Setup

5.1 Charging the Device

The NF-859GT Transmitter and Receiver units are equipped with rechargeable lithium batteries. Connect the provided Type-C charging cable to the charging port on each unit and to a standard USB power adapter (not included). The power indicator will show charging status.

5.2 Powering On/Off

Press and hold the On/Off Key on both the Transmitter and Receiver units to power them on or off.

6. Operation

The NF-859GT offers a variety of testing modes accessible via the Transmitter's main menu.

6.1 Cable Continuity Test (CONT)

This function tests the continuity of RJ45, RJ11, CAT5/5e/6/6a network cables and telephone lines.

1. Connect one end of the cable to the Local Test M Port on the Transmitter.
2. Connect the other end of the cable to the Remote Alignment Test A Port on the Receiver.
3. On the Transmitter, navigate to the CONT function and press OK.
4. The screen will display the wiring sequence and identify any open circuits, short circuits, or cross-connections.

6.2 Wire Tracing/Scanning (SCAN)

Use this function to locate a specific cable among a bundle of cables.

1. Connect one end of the cable to the Local Test M Port on the Transmitter.
2. On the Transmitter, select the SCAN function. Choose between Digital Mode or Analog Mode based on environmental interference.
3. Use the Receiver's probing rod to trace the cable. The signal strength indicator and audible tone on the Receiver will guide you to the correct cable.
4. Adjust the Receiver's Sensitivity Adjustment Knob for optimal tracing.

6.3 Port Flashing

This feature helps locate the corresponding port on a switch or hub by making its indicator light flash.

1. Connect the Transmitter's Local Test M Port to an active port on a network switch or hub.
2. On the Transmitter, select the Port Flash function.
3. The connected port's indicator light on the switch will flash, allowing for easy identification. The device also displays port information such as operating speed and duplex mode.

6.4 POE Test

Detects Power over Ethernet (POE) voltage, polarity, and non-standard POE devices.

1. Connect the network cable from the POE source to the POE Test Port on the Transmitter.
2. On the Transmitter, select the POE function.
3. The screen will display POE voltage, power supply type (e.g., 802.3af, 802.3at), and pin configuration.
