Persediaan

Before beginning fault location, ensure the UAT-600-T transmitter and AF-600 A-Frame are properly set up.

1. Connect the A-Frame: Connect the AF-600 A-Frame accessory to the UAT-600-T transmitter. This combination is essential for accurate ground fault detection.
2. Mod Pemancar: Set the UAT-600-T transmitter to the "direct test lead connection" mode. This ensures the correct signal is transmitted for the A-Frame to detect.
3. Signal Selection: On the transmitter, select either "A-Lo" (A-Frame low signal) for higher accuracy pinpointing, or "A-Hi" (A-Frame high signal) if the line to be surveyed is long or the fault resistance is high.
4. Signal Strength Output: Set the signal strength output on the transmitter to "1". Only increase this setting if the resulting signal strength is poor, to avoid signal overflow.

Arahan Operasi

Follow these steps to effectively locate ground faults using the Amprobe AF-600 A-Frame.

1. Hidupkan kuasa: Turn on the AF-600 A-Frame unit.
2. Kedudukan Awal: Use the left/right indicator arrows on the A-Frame's display to position the A-Frame directly over the cable. Begin this process near the transmitter.
3. Walking the Line: As you walk along the route of the line, allow a couple of seconds for the readings to stabilize. Place the spikes of the A-Frame into the ground approximately every two or three paces.
4. Approaching the Fault: In the proximity of the fault, maintain the A-Frame aligned with the cable using the left/right arrows. The A-Frame will detect the fault signal, and the fault direction compass arrow will point forward.
5. Crossing the Fault: When you cross the exact location of the fault, the compass arrow will change direction. Simultaneously, the two-digit fault signal level will begin to decrease as you move away from the fault.
6. Pinpointing the Fault: To pinpoint the fault accurately, carefully place the A-Frame both immediately before and immediately after the point where the compass direction changes and the signal level starts to decrease. The point of maximum reading just before the direction change, and the point of minimum reading just after, will help in precise fault identification.

Menyelesaikan masalah

If you encounter issues while using your Amprobe AF-600 A-Frame, consider the following common troubleshooting steps:

• No Signal/Weak Signal:
  • Ensure the UAT-600-T transmitter is powered on and correctly connected to the line being tested.
  • Verify that the transmitter is set to the appropriate A-Frame signal mode (A-Lo or A-Hi).
  • Check the signal strength output on the transmitter and increase it if necessary, but avoid excessive levels.
  • Ensure the A-Frame spikes are making good contact with the ground.
  • Replace batteries in both the A-Frame and the transmitter if they are low.
• Bacaan tidak konsisten:
  • Ensure you are walking at a consistent pace and placing the A-Frame spikes evenly.
  • Check for external interference from other active lines or strong electromagnetic fields.
  • Verify that the A-Frame is aligned correctly with the cable path.
• Unit Tidak Dihidupkan:
  • Check that the batteries are correctly inserted and fully charged.
  • Ensure the battery compartment is clean and free of corrosion.

If problems persist after attempting these steps, contact Amprobe customer support for further assistance.
