6. Buried Cables And Pipes: 
Transmitter Connections
Perform a battery test. Use one of the following three methods to produce a trace signal 
on the target pipe or cable.
A.  Direct Connect Method
! WARNING
This WARNING applies to the use of the Direct Connect Cables and the Transmitter.
To avoid potential shock, or electrically damaging the Transmitter, when setting up the 
Transmitter to locate using the Direct Connect method, follow these basic steps;
•    ALWAYS plug the...

2. Turn the transmitter on by pressing Ohms [T-2]. The continuity of the circuit will be 
measured. The results are displayed [T-4] in ohms and as a tone.
 
− If the continuity of the circuit is very good (the reading on the display is less 
than 3K Ω. and a solid tone from the transmitter is heard) all frequencies can 
be used to locate. Always use the lowest frequency available (for example, 577 
Hz). Lower frequencies are less likely to ‘bleed over’ to other cables in the same...

B. Dyna-Coupler Method
! WARNING
This WARNING applies to the following 3M
™ Dyna-Couplers;
• 3" (75 mm) - Part number 3001
• 4.5" (114 mm) - Part number 4001
• 6" (150 mm) - Part number 1196
•    All accessory kits containing any of the listed 3M Dyna-Couplers - Part numbers 3019, 4519, 
1196/C
A potential for electrical shock exists when using the 3M Dyna-Coupler on cables energized 
with electrical power. Use appropriate safety procedures.
DO NOT USE ON CABLES...

C. Induction Method
If you cannot make a direct connection, or use the 3M™ Dyna-Coupler clamp to apply a 
locating signal on the target, use the induction method. When nothing is plugged into the 
Output Jack [T-6] of the transmitter the unit will be placed into induction mode when it 
is turned on. This method uses the internal coil of the transmitter to generate a magnetic 
field. This is the least preferred method of applying a signal on a target conductor 
because it can...

and metal pipes), but would require increased sweep distance separation between the 
transmitter and receiver.
Note: If nothing is plugged into the Output Jack [T-6] of the transmitter, the 
transmitter will automatically turn on the internal antennae, and the la\
st frequency 
used (8 kHz (12 Watt transmitter only), 33 kHz or 200 kHz) will broadcast in induction 
mode.
The induction frequency can be changed by pressing the Frequency button \
on the 
transmitter. For best results,...

ground. Other passive sources exist, such as Cathodic Protection, LF and CATV cable 
(with NTSC TV CRT turned on).
Walk in a grid pattern over the sweep area holding the receiver as shown in the 
following illustration. Stop when there is a response increase, locate the position of the 
maximum signal, follow the conductor path all the way out of the sweep area while 
putting location marks on the ground. Resume the sweep until another cable or pipe is 
detected, or the whole...

E. Two-person Active Induction Mode Sweeps
In two-person active induction mode sweeps, one person holds the transmitter and 
the other holds the receiver while walking together in a sweep pattern detecting long 
conductors in the ground when crossed by transmitter and receiver positions and 
orientation, as shown below:
Transmitter Set-up
• Remove anything plugged into the Output Jack [T-6] (this will place unit in Induction 
Mode), select high frequency (200 kHz), or medium...

7. Receiver Modes
A.  Directional Peak (Dir Pk)
Locate/OK [5] + Cable/Pipe [SK] + Mode [SK] + Dir Pk [SK Toggle]
In Dir Pk mode, four peak antennas are used to analyze the magnetic field pattern. The 
Bar Graph [1l] indicates  Signal Strength [10] and the directional arrows sense the edges 
of the magnetic field. The left/right arrows will indicate the direction to the nearest cable 
that is in-line with the receiver handle.
As the antenna crosses the cable or pipe, the receiver...

For example:
Figure 1: If the target path is to the right of the 
receiver, and running parallel to the operator, the 
right arrow will display.
Figure 2: If the target path is to the left and in front 
of the operator (not running parallel to the receiver) 
the arrow will point toward the top left side of 
the display.
Figure 3: When the receiver crosses the target path, 
a solid line will appear, instead of arrows, indicating 
the target path and its orientation to the receiver...

D. Induction Peak (Ind Pk)
Locate/OK [5] + Cable/Pipe [SK] + Mode [SK] + Ind Pk [SK Toggle]
If you cannot make a direct connection, or use the 3M
™ Dyna-Coupler Clamp to apply 
a locating signal on the target, use the induction method. This method uses the internal 
coil of the transmitter to generate a magnetic field.
The Induction Peak mode of the receiver is a mode in which the upper antenna of the 
receiver is tuned to minimize distortion from the magnetic field of the...
