6. Operation

6.1 Cable Length Test

This function measures the length of various metal cables (network cables, telephone lines, BNC cables) with at least 2 cores.

1. Connect one end of the cable to the appropriate port on the host unit (e.g., RJ45 for network cables).
2. Select the 'LENGTH' function using the push buttons.
3. The display will show the cable length and indicate conditions like normal, short circuit, or open circuit.
4. Press the up/down arrow buttons to switch between measuring the total length or the length of individual wire pairs (e.g., pair 1 and 2, 3 and 6, 4 and 5, 7 and 8).
5. Select the cable type (8P8C, 4P4C, phone lines, BNC cables) as needed.

6.2 Cable Tracing Function

This function helps locate specific cables within a bundle or wall.

6.2.1 Analogue Tracing (Red Light, Channel 1 & 3)

1. Insert the network cable into the MAIN socket on the host unit.
2. Press the 'SCAN' button to select channel 1 or 3 to enter the analogue line-hunting state.
3. Use the receiver unit to trace the cable. The line finder will emit sound signals, and the sound size can be adjusted using the wheel.

6.2.2 Digital Tracing (Blue Light, Channel 2)

1. Insert the network cable into the MAIN socket on the host unit.
2. Press the 'SCAN' button to select channel 2 to enter the digital cable searching state.
3. Use the receiver unit to trace the cable. The blue light will flash, and the sensitivity can be adjusted.

6.3 Cable Mapping

This function checks the wiring sequence of network cables.

1. Connect one end of the network cable to the MAIN socket on the host unit and the other end to the RJ45 jack on the receiver unit.
2. Select the 'TEST' function. The display will show the wiremap status (e.g., 1-1, 2-2, etc.).
3. The speed of the mapping sequence can be adjusted.

6.4 POE Test

This function checks the Power over Ethernet (PoE) status of network switches.

1. Connect the network cable from the PoE switch to the MAIN socket on the host unit.
2. Select the 'POE' function.
3. The display will show the PoE voltage, the pins providing power, and the digital flicker status (positive).

6.5 Remote ID Mapping (Optional Accessory)

When using optional remote ID mapping accessories (7XID), you can identify multiple cables simultaneously.

1. Connect the network cable to the MAIN socket on the host unit.
2. Connect the other end of the network cable to one of the remote ID units.
3. Select the 'ID' function on the host unit. The display will show the corresponding ID number of the connected remote unit.

8. Troubleshooting

8.1 Device Will Not Power On

• Check Battery: Ensure the host unit's internal lithium battery is charged. For the receiver, verify the 9V battery is correctly installed and has sufficient charge.
• Fuse Check (ET618): If the device stopped working after a sudden event (e.g., blowing a fuse), and replacing the fuse did not resolve the issue, the internal circuitry might be damaged. In such cases, professional repair or replacement may be necessary.
• Power Button: Ensure the power button is pressed and held sufficiently to turn on the device.

9. User Tips

• Tracing Wires in Walls: The cable tracing function (Analogue or Digital) can be used to help locate where a wire runs inside a wall. The digital tracing mode with vibration can be particularly helpful for this.
• Unit of Measurement: The device primarily measures cable length in meters (M). If you require measurements in feet (ft), you will need to perform a manual conversion.
• Preventing Damage: Always ensure that the cable length measurement port is NOT connected to any Power over Ethernet (PoE) devices or other energized circuits to prevent damage to the tester.

10. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the 9V battery from the receiver unit to prevent leakage.
• Battery Care: Recharge the host unit regularly, even if not in frequent use, to maintain battery health.

11. Warranty and Support

This product comes with a 1-year guarantee. If your purchase does not meet merchantable quality, fitness for purpose, or match the description, please contact the seller for assistance.
