800-H Pipe and Cable Locator Manual

SEARCH AND SWEEP

One Person

This technique is beneficial in finding conductors with unknown

locations, and with no access points. Basically you use the

equipment in a way that scans the entire ground to find all con-

ductors in a specific area. Please read the instructions for induc-

tive locating before proceeding.

Position the Transmitter

Lay the 800-H Transmitter on its side, as shown below. This will

“flood” the area with signal. Turn ON the Transmitter.

Set Up the Receiver

Set up with the receiver the same as you would during inductive

locating. Move 5-10 feet from the transmitter, face the transmit-

ter with the antenna near the ground, and turn the receiver ON.

Set the sensitivity control so that the meter reads 4 and you

hear a LOW pitched tone.

Locate the Conductor(s)

With the receiver facing the transmitter, walk in a circle around

the transmitter. Keep a steady distance from the transmitter and

from the ground. Listen for the HIGH pitch tone areas, DO NOT

adjust the sensitivity. After locating the HIGH pitch areas, go

back and pin-point the conductors in those areas. You may need

to re-adjust the sensitivity at this step, looking for the LOW-

HIGH-LOW sound change. Mark the places with the highest

tones for further pinpointing later.
