Configuración
Before beginning fault location, ensure the UAT-600-T transmitter and AF-600 A-Frame are properly set up.
- 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.
- Modo transmisor: 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.
- 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.
- 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.
Instrucciones de funcionamiento
Follow these steps to effectively locate ground faults using the Amprobe AF-600 A-Frame.
- Encendido: Turn on the AF-600 A-Frame unit.
- Posicionamiento inicial: 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.
- 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.
- 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.
- 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.
- 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.

Video Demonstration: Ground Fault Location with Amprobe UAT-600 A-Frame
This video provides a visual guide on how to successfully locate ground faults using the Amprobe AF-600 A-Frame accessory in combination with the UAT-600-T transmitter. It demonstrates the setup, signal selection, and the process of walking the line to pinpoint fault locations by observing compass direction changes and signal level variations.
Mantenimiento
Para garantizar la longevidad y el rendimiento óptimo de su Amprobe AF-600 A-Frame Ground Fault Locator, regular maintenance is recommended.
- Limpieza: After each use, especially in dirty or wet conditions, wipe down the A-Frame and its components with a clean, damp cloth. Ensure all parts are dry before storing.
- Reemplazo de batería: The unit requires 6 AA batteries. If the display indicates low battery or the unit's performance degrades, replace all batteries with new ones. Always use the specified battery type.
- Almacenamiento: Store the A-Frame in its provided carrying case in a dry, cool environment, away from direct sunlight and extreme temperatures.
- Inspección: Periodically inspect the spikes, cables, and housing for any signs of wear, damage, or corrosion. If any damage is found, contact Amprobe customer support for repair or replacement.
Solución de problemas
If you encounter issues while using your Amprobe AF-600 A-Frame, consider the following common troubleshooting steps:
- Sin señal/señal débil:
- 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.
- Lecturas inconsistentes:
- 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.
- La unidad no se enciende:
- Compruebe que las baterías estén correctamente insertadas y completamente cargadas.
- Asegúrese de que el compartimento de la batería esté limpio y libre de corrosión.
If problems persist after attempting these steps, contact Amprobe customer support for further assistance.
