AP-027 operation for utilities tracing

Move to the supposed utility location - an energized cable or a pipe. During the operation there will be information on the screen and sound in the headphones.

AP-027 operation for utilities tracing

  1. The signal is low on the screen and in the headphones, it means the utility is far away from the operator.
  2. The closer to the utility the higher is the signal on the screen and the louder is the sound in the headphones.
  3. The operator is above the utility, the signal is maximum.
  4. The signal is less, it means the leakage was behind.
