Amprobe AF-600 A-Frame Cable Ground Fault Locator

  • Optional accessory for Amprobe UAT-600 Underground Utilities Locator Series
  • Works in conjunction with the UAT-600-T Transmitter
  • Locate cable and wires ground faults, sheath faults or pipeline coating defects (direct contact of the utility with the ground is required to pinpoint a fault)
  • Used to find the point where metal is touching the ground (shield is rusted/rubber buffer is broken) and power is leaking, creating noise on a cable
  • Find the point of leakage around a cable (ground faults are common problems with electric cables) – saves money by pinpointing leakage point
  • Adjustable volume control
  • Advanced technology and digital signal processing makes pinpointing process fast, accurate and unambiguous:
      1. Compass guidance with numeric fault field strength indicates direction to the place of the fault
      2. Distance sensitive left/right guidance guides the user to precisely follow the path of the buried utility
      3. Automatic gain control quickly detects tracing signal and precisely adjust A-Frame sensitivity
