Use the Up/Down/Left/Right navigation buttons to select options on the LCD screen. Press the OK button to confirm a selection. The Back button returns to the previous menu.

4. Operating Instructions

4.1 Cable Continuity Testing (Mapping)

This function checks for short circuits, open circuits, and crossover connections in network cables (RJ45, RJ11) and BNC cables.

1. Connect one end of the cable to the appropriate port (RJ45 MAIN, RJ11, or BNC) on the main unit.
2. For remote testing, connect the other end of the cable to the Wiremap Remote unit (for RJ45) or the receiver unit (for RJ11/BNC). For local testing, connect both ends to the main unit if applicable.
3. From the main menu, select "Mapping" and press OK.
4. The LCD will display the wiring diagram, indicating any faults such as opens, shorts, or crossovers.

4.2 Cable Length Measurement

The AT278 uses TDR technology to accurately measure cable length and identify the distance to a fault.

1. Ensure the cable is disconnected from all network devices.
2. Connect one end of the cable to the RJ45 MAIN, RJ11, or BNC port on the main unit.
3. From the main menu, select "Length" and press OK.
4. The device will display the measured length of each wire pair and the distance to any detected faults.

4.3 Cable Scan (Wire Tracking)

This function helps locate a specific cable among a bundle of cables.

1. Connect one end of the cable to the RJ45 SCAN port on the main unit.
2. From the main menu, select "Scan" and press OK. The main unit will emit a tone.
3. Turn on the receiver unit and adjust the volume.
4. Move the receiver's probe along the cable bundle. The tone will be loudest when the receiver is near the target cable.

4.4 POE Power Supply Test

This test identifies if Power over Ethernet (PoE) is present on a cable and measures its voltage.

1. Connect the network cable from the PoE source to the RJ45 MAIN port on the main unit.
2. From the main menu, select "POE" and press OK.
3. The display will show the PoE standard, voltage, and power supply mode (e.g., End-span, Mid-span).

4.5 PING Test

The PING test assesses network connectivity and response times.

1. Connect the main unit to an active network port using an RJ45 cable.
2. From the main menu, select "Ping" and press OK.
3. Enter the IP address of the target device (e.g., router, server) using the navigation buttons.
4. Press OK to start the PING test. The results will show packet loss, minimum, maximum, and average response times.

4.6 Port Flash

This function helps locate the corresponding port on a network switch or router by making its indicator light flash.

1. Connect the main unit to an active network port using an RJ45 cable.
2. From the main menu, select "Port Flash" and press OK.
3. The main unit will send a signal that causes the connected port's LED on the switch/router to flash, allowing for easy identification.

4.7 NCV (Non-Contact Voltage) Function

The receiver unit includes an NCV sensor to detect AC voltage without direct contact.

1. Turn on the receiver unit.
2. Move the NCV sensor (tip of the receiver) close to an AC voltage source (e.g., live wire, power outlet).
3. If AC voltage is detected, the receiver will emit an audible alarm and/or visual indication.

4.8 Data Transmission (TF Card)

The AT278 allows saving test results to a TF card for later analysis on a computer.

1. Ensure a TF card is inserted into the main unit's TF card slot.
2. During or after a test, follow the on-screen prompts or menu options to save the data.
3. To view data, remove the TF card and insert it into a computer's card reader.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
• Storage: Store the device in its carrying case in a cool, dry place when not in use. Avoid extreme temperatures and humidity.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the device regularly, even if not in active use, to maintain battery health.
• Firmware Updates: Check the manufacturer's website periodically for any available firmware updates to ensure optimal performance and access to new features.

6. Troubleshooting

• Device Not Powering On: Ensure the battery is sufficiently charged. Connect the device to a power source using the USB charging cable and allow it to charge for at least 30 minutes before attempting to power on again.
• Device Shuts Off Unexpectedly: Check battery level. If the issue persists after a full charge, ensure no power-saving settings are configured to an excessively short duration. Contact support if the problem continues.
• Inaccurate or Inconsistent Test Results:
  • Ensure cables are properly terminated and securely connected to the tester ports.
  • Verify that the cable type selected in the device settings matches the cable being tested.
  • For length measurement, ensure the cable is completely disconnected from all network devices.
  • Test with known good cables to calibrate or verify the tester's functionality.
• No Tone During Cable Scan: Ensure the main unit is in "Scan" mode and the receiver is powered on with adequate volume. Check that the cable is properly connected to the RJ45 SCAN port.
• TF Card Not Detected/Data Not Saving: Ensure the TF card is inserted correctly. Try formatting the TF card (this will erase all data) or use a different TF card.
