2. Setup

2.1 Battery Installation

The FY8176 main unit and receiver require 1.5V AAA batteries for operation. Ensure batteries are inserted with correct polarity.

1. Locate the battery compartment on the back of both the main unit and the receiver.
2. Open the battery compartment cover.
3. Insert the required 1.5V AAA batteries, observing the polarity markings (+/-).
4. Close the battery compartment cover securely.

2.2 Initial Power On

Press and hold the power button on the main unit to turn it on. The LCD screen will illuminate, indicating the device is ready for use.

3. Operating Instructions

3.1 Network Line Finding (Wire Tracking)

The FY8176 features strong digital signal induction for accurate and anti-interference wire tracking, including PoE live line finding.

1. Connect the network cable to be traced to the RJ45 port on the main FY8176 unit.
2. Turn on the receiver unit.
3. Move the receiver along the path of the cable. The receiver will emit an audible tone and/or illuminate LEDs to indicate the presence of the signal, helping you locate the cable.
4. For PoE live line finding, the device is designed to operate without interference from active PoE signals.

3.2 Network Cable Length Test

This function allows you to measure the length of network cables, including shielded wires, from 2 meters to 400 meters. It can also measure the length of individual core paths within the cable.

1. Connect one end of the network cable to the RJ45 port on the main FY8176 unit. Ensure the other end of the cable is disconnected from any device.
2. Select the length measurement mode on the FY8176.
3. The LCD screen will display the measured length of the cable in meters.

3.3 Breakpoint Detection

When measuring cable length, the FY8176 can also help determine the position of a breakpoint in the network cable.

1. Perform a network cable length test as described in Section 3.2.
2. If a discontinuity or breakpoint is detected, the device will display the length up to the point of the break. This allows for precise identification of the breakpoint location.

3.4 Network Cable Sequence Detection (Wiring Map Test)

The FY8176 can check the sequence of network cables and perform a wiring map test. The transmitter can be directly connected to a switch for wiring checks.

1. Connect one end of the network cable to the RJ45 port on the main FY8176 unit.
2. Connect the other end of the network cable to the receiver unit.
3. Select the wiring map test mode on the FY8176. The LCD will display the wiring sequence, indicating any open circuits, short circuits, or cross-overs.
4. The test can be performed in 'Fast' or 'Slow' modes for detailed observation.
