7.2 Cable Mapping (Wiremap Test)

This function tests for open circuits, crossovers, short circuits, and other wiring faults in network cables.

Connect one end of the network cable to the main unit's RJ45 port.
Connect the other end of the cable to the receiver unit's RJ45 port.
Select the 'TEST' or 'SCAN' mode on the main unit.
The screen will graphically display the wiring status, indicating normal connections, open circuits, short circuits, or cross-overs.

7.11 Low Battery Detection and Auto Power Off

The device features a low battery detection function, which will alert you when the battery needs charging or replacement.
To conserve battery life, the device is equipped with an auto power-off feature that activates after a period of inactivity.

8. User Tips

For accurate cable length measurements, ensure the cable is fully uncoiled and free of kinks.
When tracing cables in noisy environments, adjust the receiver's sensitivity carefully to minimize interference.
Always double-check your connections before performing any tests, especially when using multimeter functions with live circuits.
Keep the screen clean with a soft, dry cloth to maintain visibility.

9. Maintenance

9.1 Cleaning

Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Ensure no moisture enters the ports or openings.

9.2 Storage

Store the device in its original storage box in a cool, dry place when not in use.
Remove the 9V battery from the receiver if storing for extended periods to prevent leakage.

9.3 Battery Replacement (Receiver)

When the low battery indicator appears for the receiver, replace the 9V battery.
Open the battery compartment, remove the old battery, and insert a new one, ensuring correct polarity.

10. Troubleshooting

If you encounter issues with your device, refer to the following common problems and solutions:

Device does not power on: Check if the main unit is charged or if the receiver's 9V battery is installed correctly and has sufficient power.
Inaccurate cable length measurement: Ensure the cable is fully uncoiled and properly connected. Verify the cable type setting if applicable.
Cable mapping shows errors on a known good cable: Re-crimp the RJ45 connectors or try a different cable to isolate the issue. Ensure connections are secure.
Cable tracing is difficult or noisy: Adjust the receiver's sensitivity. Ensure there are no strong electromagnetic interference sources nearby.
Multimeter (ET623) shows 'OL' or incorrect readings: Check test lead connections, ensure the correct measurement mode is selected, and verify the component being tested is within the device's range.
