78-8130-6151-8-E 15
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.
Direct Connect Method
Plug the direct connect cable into the output jack [T-6] of the transmitter. Connect the
black clip to the ground rod. Place the ground rod in the earth perpendicular to the
suspected cable/pipe path. If necessary, extend the black lead with the Ground Extension
Cable (#9043 available separately).
1. Remove the ground bonding and attach the red clip to the shield of the cable, pipe,
or target conductor. (If locating power cables, the red clip can be attached to the
transformer cabinet, or the meter box).
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. Lower frequencies are
less likely to ‘bleed over’ to other cables in the same area, and are very good for
tracing over long distances.
− If the circuit reads more than 3K Ω., but less than lOK Ω(indicated by a beeping
tone from the transmitter) it will be necessary to use a higher frequency than 512
Hz or 577 Hz in order to locate the cable/pipe.
− If the circuit reads more than lOK Ω., it will be necessary to use an RF signal
such as 33 KHz or 133 KHz.
− If there is no tone and the transmitter indicates that there is an open circuit (OL
in the display) this could be an indication of a poor ground, or an open-ended
cable or pipe. Use one of the higher frequencies available, at high level. If it is
an open-ended cable or pipe, the receiver's response will decrease suddenly at
the site of the clear or severed end.

16 78-8130-6151-8-E
Note: In the ohms mode, the transmitter can detect voltage as well as ohms. If a low
voltage is detected, the display will alternate between displaying ohms and volts. When
displaying ohms, the flag over the Ωsymbol will be visible. When displaying volts, the
flag over the ‘V' will be visible. When the voltage magnitude is sufficient to impair the
accuracy of the ohms measurement, only voltage will be displayed. If the voltage is
AC, a sine wave will be visible on the display [T--4]. If a high AC voltage is detected, a
rapid beeping tone will be heard.
3. Press the Trace [T-3] repeatedly until the desired frequency appears on the display.
4. Press Output [T-5] to select high output level for longer tracing distances or deep
pipe/cable.
Dyna-Coupler Method
1. Connect the Dyna-Coupler to the transmitter output jack [T-6] using the coupler
cable (9011).
2. Clamp the Dyna-Coupler around the cable or pipe, below any bonds, just before it
enters the earth. The jaws of the coupler must fully close.
3. Press Trace [T-3] to turn on the transmitter. Press again to select 8 KHz, 33 KHz or
133 KHz.
Note: When using a Dyna-Coupler, always select high output level by pressing the
output key [T-5] on the transmitter.

78-8130-6151-8-E 17
Induction Method
If you cannot make a direct connection, or use the 3M™ Dynatel™ 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. This is the least preferred
method of applying a signal on a target conductor because it can easily be picked up by
other non-target conductors in the area. However, it is the preferred method of applying
a signal to multiple cables/pipes in the same trench, and for the ‘two-man sweeping’
application.
1. Verify battery level of transmitter and remove any cables from the output jack.
2. Position the transmitter over the target facility with the hinge of the transmitter over
and in line with the cable/pipe path.
3. Align the Induction Direction arrows on the transmitter with the target conductor.
4. Turn on the transmitter by pressing the Trace [T-3] key.
5. Press Trace [T-3] again to select 33 KHz or 133 KHz.
6. Select High Output level for the best signal-to-noise ratio.
7. Trace the signal path with the receiver using the Induction Peak mode.
The induction 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 transmitter.
Note: The receiver must be at least 25 feet away from the transmitter to begin tracing
the target path.

18 78-8130-6151-8-E
Receiver Modes
Directional Peak
MODE + Directional Peak (DirPk) [SK Toggle]
In DirPk mode, four peak antennas are used to analyze the magnetic field pattern. The
bar graph indicates signal strength 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 speaker volume increases to a
maximum, the bar graph [1l] fills from both sides toward the middle, and the numeric
signal strength [10] increases. As the antenna moves off the target path, the speaker
volume decreases and the bar graph opens. Use the bar graph and the numeric signal
indicator to locate the exact target path.
Left of Target Path Directly Over Target Path Right of Target Path
Once the target path has been located, the arrows at the top of the screen will indicate
the location of the target path in relationship to the receiver.
Note: When field distortion (due to congestion) is affecting the receiver the left/right
arrows may not coincide with the bar graph. Use the maximum numerical signal
strength to target the cable or pipe.
Directional Null
MODE + (DirNull) [SK Toggle]
In DirNull mode, as the operator approaches the cable or pipe, the numerical signal will
increase then fall sharply as the receiver crosses the target cable or pipe. The bar graph
fills from both sides toward the middle and the receiver speaker volume decreases. As
the antenna moves off the target path, the bar graph opens, the signal strength increases,
and the speaker volume increases. Gain adjust is automatic in DirNull mode.
The center of the DirNull screen provides a ‘compass view' of the target path. An arrow
will point toward the location of the cable/pipe in 45-degree steps. A solid line will
appear over the cable/pipe, indicating its orientation to the receiver handle.

78-8130-6151-8-E 19
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 screen.
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.
Before marking target path, always use directional peak or special peak mode to verify
location.
Special Peak
MODE + (Spl Pk) [SK Toggle]
Special Peak Mode turns on only the peak antenna closest to the ground. Special Peak
Mode is used in applications such as very deep cable, or when the signal is too weak for
normal or directional peak tracing.
Inductive Peak (IndPk)
MODE + IndPk [SK Toggle]
If you cannot make a direct connection, or use the 3M™
Dynatel™ 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 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 transmitter.

20 78-8130-6151-8-E
Expanded Mode
When the third ring of the speaker icon is dotted or broken and ‘xpnd’ appears below the
speaker icon, the receiver is in “Expanded” mode. This mode is used for pinpointing a
target cable or pipe. The area of response of the receiver narrows, allowing the locator to
detect very small signal changes.
Depth and Current Estimate
Verifying the target path, depth and current can be helpful tools.
1. Pinpoint the cable or pipe being located.
2. Lower the tip of the receiver to the ground and
press Depth [SK].
− The depth to the target cable or pipe is
displayed in the units specified in the
receiver set up menu. The bold current
reading is a relative current measurement.
This reading can be compared to the current
reading that alternately flashes with the
frequency on the transmitter. The milliamp
reading is an actual current measurement.
− There are two options for measuring depth.
Live depth is a continuous measurement.
1-Shot Depth is an averaging of the depth
reading. When in 1-Shot mode, the unit will
average the depth reading for three seconds,
and then display the result on the screen.
Press Depth [SK] to alternate between the
two modes.
− Five depth readings can be saved with the
time, date and relative current measurements.
3. Pressing Save [SK] will place each entry in sequential order in memory (M1 - M5)
until five readings have been stored. The unit will overwrite saved entries in excess
of five, beginning with M1.
