5. LOOP MODE
NOTE: The Loop Mode requires the optional
Cable Drum with 50 meter cable, or
make up your own length of wire cable.
The Loop Mode (or method) is often useful
for locating water mains and service lines
in areas with congested utilities. The Trans-
mitter is operated in the Direct Connection
Mode, and cables are used to directly con-
nect the positive and negative leads from
the Transmitter to the ttings that bracket
the line to be located.
1. Look for two ttings/connections to the
system that bracket the line to be located.
Service line meters, hydrants, and valves
are all suitable in water distribution
systems, but the pipes must all be metal
(and not plastic).
2. Connect the positive lead (red) cable down
to the further-most tting and the negative
lead (black) cable to a nearby tting.
3. Set the Transmitter to 8 kHz (or .5 kHz
for completely continuous conductors) to
minimize signal “jumping.”
4. Locate the buried pipeline with the Receiver
between the two ttings (1) and (2).
NOTE: Any pipelines beyond the ttings will
not be located by use of the Loop
Mode. The signal only ows between
the two ttings.

INDUCTIVE CLAMP MODE
1. The Inductive Clamp Mode is used to
energize insulated wires such as tele-
phone lines and low power electric lines.
The Transmitter is operated in the Direct
Mode, and the cables for the Inductive
Clamp must be plugged into the connec-
tor on the side of the Transmitter.
2. Open the jaws of the Inductive Clamp
and close them around the insulated
cable. The ground shield for the cable
should be attached to ground at the op-
posite end of the line to be traced. Switch
the Transmitter and Receiver to 27 kHz
to induce the strongest signal in the insu-
lated line.
NOTE: The Inductive Clamp Mode requires
the optional Inductive Clamp as
shown above.
NOTE: When the Inductive Clamp is
clamped around a power cable,
wear Rubber Gloves as a safety
precaution to avoid electric shock.
