There are two basic models included in the 3M™ Dynatel™ Locator 2200M Series. The
2250M locator is designed for cable/pipe locating. The 2273M locator is designed for
cable/pipe and fault locating. The iD option (read/write capability to 3MTM iD Markers)
is available for both models. There are three transmitter options: 3 Watt, 5 Watt, or 12
Watt. This instruction manual will include all features. All instructions are applicable to
all products, unless noted.
The 12-watt transmitter option offers additional power output levels for improved
induction performance and 8 kHz (low frequency) induction for shallow facilities, such
as risers. Output Power up to 12 Watts for the 12-watt transmitter is achieved using the
supplied external power source. The maximum output power in Direct Connect method
is reduced to below FCC limits. (FCC limits: 1 Watt at 200 kHz and 10 Watts at 33 kHz)
In order to demonstrate all available functions, the illustrations depict the 2273M-iD
receiver unit and the 2250 and 2273 12-watt transmitters. The 2250M receiver may vary

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 Direct Connect Cable into the Transmitter Output Jack [T-6] BEFORE
connecting the leads to the cable/pipe to be located and the ground rod.
– Connect the red lead to the cable/pipe.
– Connect the black lead to ground rod.
A POTENTIAL FOR ELECTRICAL SHOCK, AND/OR TRANSMITTER ELECTRICAL DAMAGE, EXISTS
WHEN USING THE DIRECT CONNECT CABLE ON CABLES ENERGIZED WITH ELECTRICAL POWER
IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED. USE APPROPRIATE SAFETY PROCEDURES.
CHECK VOLTAGE BEFORE CONNECTING TRANSMITTER. VOLTAGE HIGHER THAN 240 VOLTS WILL
DAMAGE EQUIPMENT. FOLLOW STANDARD PROCEDURES FOR REDUCING THE VOLTAGE.
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). Metal contact must be made between the red
clip and the transformer cabinet or meter box. If painted, some paint will need to be
removed/scraped off to allow metal-to-metal contact.

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
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 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 200 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 or maximum
output power 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.
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 Ω symbol 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 Trace [T-3] repeatedly until the desired frequency appears on the display.
4. Press Output Level [T-5] to select high or maximum output power level for longer
tracing distances or deep pipe/cable.

78-8130-6150-0 Rev G
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 CARRYING IN EXCESS OF 600 VOLTS RMS.
Use a ground extension cable,
or wire, and ground rod set-up
between a target pipe/cable and
a gas meter valve/box, or cable/
electrical meter box. This will
isolate the locate signal to the
target pipe/cable section below
the meter/box, between the
grounding points. This provides a
good return path for the tracing
signal. Insulating coupling above
a gas meter valve on a pipe will
isolate the returning signal from
ground and may make locating
more difficult.
1. Connect the 3M Dyna-Coupler to the transmitter Output Jack [T-6] using the
coupler cable (9011).
2. Clamp the 3M 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
200 kHz.
Note: When using a 3M Dyna-Coupler, always select high or maximum output power
level by pressing the Output Level [T-5] key on the transmitter.

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 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-person sweeping’ application.
3M Dynatel transmitters provide a choice of induction frequencies and output power
levels. Higher induction output power levels are needed for detecting deeper depths and
longer ranges. The 2200M Series 3 Watt transmitters provides two induction frequencies:
33 kHz and 200 kHz. The 12 Watt transmitter provides three induction frequencies: 8
kHz, 33 kHz and 200 kHz. The 200 kHz frequency is commonly used for deeper cables/
pipes and the lower frequencies are used to give longer locate distances. The 8 kHz
(low frequency) induction helps in locating shallow facilities, such as risers (12 Watt
transmitter only.)
The following sections review Non-sweeping and Sweeping (Area) methods used
with the Induction Mode. The Non-Sweeping method is utilized when a specific target
requires path tracing. The transmitter remains stationary in-line over the target and the
path is traced. The Sweeping method is utilized when a designated area needs to be
swept for non-specific targets, for example, all the buried pipes or conductors in the
designated area. Several sweeping methods will be reviewed.
A. Non-Sweeping (Passive) Induction Mode Locating
• Position the transmitter over the target facility, with the hinge of the transmitter over
and in line with the cable/pipe path. Remove any cables from the Output Jack [T-6].
− Align the Induction Direction arrows on the transmitter with the target
conductor.
• Turn on the transmitter, select the frequency and select high output or maximum
output power level for best signal-to-noise ratio.
• Trace the signal path with the receiver using the Induction Peak (Ind Pk) mode.
The Induction Peak (Ind Pk) 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.
Use Induction Peak (Ind Pk) mode when sweeping distance between the transmitter and
receiver is 25–60 feet (7.6–20 m). Beyond 60 feet (20 m) you can also use the Special
(single) Peak (Spl Pk) or Directional Peak (Dir Pk) modes. Special (single) Peak (Spl
Pk) can be used for maximum detection depth and range (needed for deep conductors
24
78-8130-6150-0 Rev G
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 last 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, the receiver should be at least 25 feet (7.6 m) away from
the transmitter to begin tracing the target path and have the gain set between 78-84%
when starting the sweep. This is used to establish a baseline gain threshold prior to
starting a sweep. When crossing a target pipe or cable, the bar graph will close and
the signal strength and audio response will increase. Attempting to trace the target
close to the transmitter may lead to false indications due to the receiver detecting the
large magnetic field radiating from the transmitter.
B. Sweeping (Active) Induction Mode Locating
Sweeping an area with the 3M™ Dynatel™ Locator 2200M Series allows the location of
multiple metallic cables and pipes buried in an area without direct connect or coupler
access to the cable or pipe. This approach is effective before any excavation takes place.
Note that when specific buried objects need to be identified, it's important to use the
direct connect or coupler method for applying the signal. This will help limit the applied
locate signal to a specific facility that provides more position and depth accuracy along
with an effective identification. There are two main types of “no access” or “blind”
Induction Sweeps;
Passive Sweeps: These require only the use of the Receiver with passive frequency
detection capability. This method uses existing external signal sources, such as 60 Hz/50
Hz for electric power, 15 kHz to approximately 30 kHz for low frequency radio signals,
120 Hz / 100 Hz CPS impressed current Cathodic Protection signals and the less
commonly occurring CATV signal of 31.25 kHz NTSC with CRT TV turned on.
Active Sweeps: These require both the Receiver and Transmitter with Induction
capability. This method refers to using a 3M Dynatel transmitter as the signal source
through induction, instead of relying on passive frequencies that may exist on the
buried conductor or metal pipe. Active Induction allows for detecting buried cables
and metal pipes in the absence of passive signals and at deep depths and short sections.
3M Dynatel transmitters provide a choice of induction frequencies and output power
levels. Higher induction output power levels are needed for detecting deeper depths and
longer ranges. The 2200M Series 3 Watt transmitters provides two induction frequencies:
33 kHz and 200 kHz. The 12 Watt transmitter provides three induction frequencies: 8
kHz, 33 kHz and 200 kHz. The 200 kHz frequency is commonly used for deeper cables/
pipes and the lower frequencies are used to give longer locate distances. The 8 kHz (low
frequency) induction helps in locating shallow facilities, such as risers.
C. Passive Sweeps
Select Special (single) Peak (Spl Pk) mode on the receiver and then select the frequency
(source; for example, power, LF, etc.) to be traced. Passive sweeps at power frequency
will detect buried power cables and conductors carrying 60 Hz/50 Hz power signal in the
78-8130-6150-0 Rev G
25
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 area is completely swept. Switch to another available passive
frequency in the receiver and sweep again.
D. One-person Active Induction Mode Sweeps
One-person active induction mode sweeps require that the transmitter be set on the
ground over the suspected path of the buried infrastructure. The receiver is used to
detect signals induced by the transmitter on buried long conductors. Proper placement
and orientation is key to maximize the induced signal in the buried cable or metallic
pipe enough to be detectable by the receiver along each path in the swept area. (Note
that no signal is induced onto a conductor whose path is perpendicular to the Induction
Direction indication.)
• Place the transmitter in the upright (bottom on ground) position for directional
optimization when aligned with the Induction Direction shown on the label on the
transmitter.
• Tip the transmitter over towards the front, and lay it on it's front surface, for multi-
directional wide area induction. (Note that no signal is induced onto a conductor
whose path is directly under the transmitter).
• Remove anything plugged into the Output Jack [T-6] (this will place unit in Induction
Mode), select highest available frequency (200 kHz) and highest output power level.
• Select the Induction Peak (Ind Pk) mode and 200 kHz frequency on the receiver.
When in close proximity to the transmitter in induction mode, there is a direct signal
from the induction antenna in the transmitter to the receiver through the air. Induction
Peak (Ind Pk) mode is a newly added locate mode for use in closer proximity to a
transmitter in Induction mode (<60 ft , 20 m typ.). Special (single) Peak (Spl Pk)
would give the highest sensitivity, but is affected by the air signal more than Induction
Peak (Ind Pk) mode.
26
78-8130-6150-0 Rev G
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 frequency (33 kHz or 82 kHz),
and highest output power level.
• Hold the transmitter with the lid facing up and align it with the Induction Direction
arrow label, as shown on the transmitter, with the receiver
Receiver Set-up
• Set the receiver to the same frequency as the transmitter.
• Select the Induction Peak (Ind Pk) mode, and press the Gain Adjust [4] (+ or -) key
until the bar graph is just visible.
Sweeping
• Sweeping can be done at close distances between the transmitter and receiver.
• For best results, the receiver should be at least 25 feet (7.6 m) away from the
transmitter to begin tracing the target path and have the gain set between 78-84%
when starting the sweep. Attempting to trace the target close to the transmitter may
lead to false indications due to the receiver detecting the large magnetic field radiating
from the transmitter.
• Induction Peak (Ind Pk) mode cancels the air signal coming directly from the
transmitter induction antenna to the receiver. Increasing the sweep distance between
the transmitter and receiver reduces the direct air signal and allows for sensing
deeper conductors and sections of metal pipes. Use Induction Peak (Ind Pk) mode
when sweeping distance between the transmitter and receiver is 25–60 feet (7.6–20
m). Beyond 60 feet (20 m) you can also use the Special (single) Peak (Spl Pk) or
Directional Peak (Dir Pk) modes.
• Special (single) Peak (Spl Pk) can be used for maximum detection depth and range
(needed for deep conductors and metal pipes), but would require increased sweep
distance separation between the transmitter and receiver.

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 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 [1l] opens. Use the Bar Graph [1l] and the numeric
Signal Strength [10] value to locate the exact target path.
Right of Target Path
Left of Target Path
Directly Over Target Path
Once the target path has been located, the arrows at the top of the display 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.
B. Directional Null (DirNull)
Locate/OK [5] + Cable/Pipe [SK] + Mode [SK] + DirNull [SK Toggle]
In DirNull mode, as the operator approaches the cable or pipe, the numerical Signal
Strength [10] will increase then fall sharply as the receiver crosses the target cable
or pipe. The Bar Graph [1l] fills from both sides toward the middle and the receiver
speaker volume decreases. As the antenna moves off the target path, the Bar Graph [1l]
opens, the Signal Strength [10] increases, and the speaker volume increases. Gain adjust
is automatic in DirNull mode.
The center of the DirNull display 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.
28
78-8130-6150-0 Rev G
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
handle.
Before marking target path, always use Directional Peak (Dir Pk) or Special Peak (Spl
Pk) mode to verify location.
C. Special Peak (Spl Pk)
Locate/OK [5] + Cable/Pipe [SK] + Mode [SK] + 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 cables or pipes, or when the signal is too
weak for directional peak tracing.
Left or Right of Target Path
Directly Over Target Path
78-8130-6150-0 Rev G
29
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 transmitter.
Left or Right of Target Path
Directly Over Target Path
E. Expanded Mode
When the third ring of the speaker icon is dotted
or broken and ‘xpnd’ appears below the speaker
icon as shown, 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. Press the
Speaker Volume Control [2] key to activate the
"Expanded" mode.
8. 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 to help identify the target cable/
pipe. The highest relative current value will
be the target cable/pipe and will compare
closest to the transmitter relative current value.
The milliamp reading is an actual current
measurement.
30
78-8130-6150-0 Rev G
− There are two options for measuring depth.
Live depth is a continuous measurement.
1-Shot Depth is an averaging of the depth
reading over a short period of time. When in
1-Shot mode, the unit will average the depth
reading for three seconds, and then display
the result on the display. 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.
4. Press Clear All [SK] to delete all stored depth
information.
− The operator may select the memory location
to store the depth readings by pressing Mem
Select [SK]. When the preferred location
appears on the display, press Save [SK]. The
display and memory location will populate
with the current information.
− Each memory location can be reviewed by
pressing Mem Select [SK].
5. Press Locate/OK [5] to return to Locate Mode.
9. Locating Frequencies
A. Active Frequencies
Active frequencies are trace signals supplied by a 3M™ Dynatel™ Transmitter 2200
Series (577 Hz, 8 kHz, 33 kHz, or 200 kHz).
1. Select the same frequency that the transmitter is generating.
2. Press Locate/OK [5]

31
B. Power Frequencies
Power frequencies refer to 50 or 60 Hz signals, and their harmonics, that can be traced
without the use of a transmitter.
60: Best for general locating of passive power.
60H (high harmonic): If the 60 choice appears to be responding slowly, or poorly, then
60H is the second choice for locating of passive power.
60L (low harmonic): Third choice for passive power locating. May be used when 60 or
60L is weak or erratic. 60L may be the best choice when locating primary power cables.
120 Hz: Used for locating rectified AC power signals, often found on pipelines using
impressed current cathodic protection.
1. Press Locate/OK [5]
2. Press Cable/Pipe [SK]
3. Press Freq [SK]
4. Press Power [SK Toggle] until the desired frequency is displayed in the soft key
command [9] (“Power” 60, 60L, 60H, or 120).
5. Press Locate/OK [5] to return to Locate mode.
All U.S. receivers default to 60 Hz.
To set the receiver to detect 50 Hz signals refer to Enabling/Disabling Frequencies
section of this manual.
C. Passive Frequencies
The receiver (without a 3M™ Dynatel™ Transmitter 2200 Series) can be used to detect
some CATV cables (31.5 kHz). (A horizontal-scan television NTSC must be turned on to
generate this frequency.)
1. Press Locate/OK [5]
2. Press Cable/Pipe [SK]
3. Press Freq [SK]
4. Press Pasv [SK Toggle]
5. Press Locate/OK [5] to return to Locate mode.
D. Auxiliary Frequencies
Auxiliary frequencies are signals generated from remote location transmitters, or
frequency generating transmitters.
1. Press Locate/OK [5]
2. Press Cable/Pipe [SK]
3. Press Freq [SK]
32
78-8130-6150-0 Rev G
4. Press Aux [SK Toggle] until the desired frequency is displayed in the softkey

5. Press Locate/OK [5] to return to Locate mode.
10. Locating in Directional Peak Mode
The following are instructions for locating a buried pipe or cable using the direct connect
method and the directional peak (Dir Pk) mode. Other methods of connection and
tracing modes/features are explained in previous sections.
1. Insert the ground rod into the ground, perpendicular to the suspected target path.
2. Remove the grounding from the near-end of the target cable/pipe.
Note: Never connect or disconnect the transmitter when the unit is on.
3. Connect the red lead of the transmitter to the shield, neutral, or deenergized target
conductor.
4. Connect the black lead of the transmitter to the ground rod.
5. Perform a battery check by pressing and holding off [T-1].
6. Power on the transmitter by pressing Ohms [T-2] once for Ohm-meter mode. An
indicator flag will be displayed above the ohms symbol (Ω) in the Digital Display
[T-4].
a. A solid tone from the transmitter indicates a complete circuit with a good
ground.
b. A beeping tone from the transmitter indicates a usable ground. An attempt
should be made to improve the ground.
c. No tone from the transmitter indicates a poor, or no ground. The transmitter will
display ‘OL’ in this instance. An attempt should be made to improve the ground.
Verify that the far end is grounded.
7. Press Trace [T-3] to set the transmitter to Trace mode.
8. Select a frequency on the transmitter by pressing Trace [T-3]. The unit will cycle
through the available frequencies (577, 8K, 33K, 200K, and ALL).
9. Press On/Off (Power) [1] to power on the receiver.
10. Press Locate/OK [5].
11. Press Cable/Pipe [SK].
78-8130-6150-0 Rev G
33
12. Set the Frequency and mode of the receiver.
a. Press Freq [SK]
b. Select the same frequency on the receiver
as the transmitter by pressing Active [SK
Toggle].
c. Press Locate/OK [5] to save the setting and
return to locate mode.
d. Press Mode [SK Toggle] until Dir Pk is
displayed.
13. Stand away from the suspected target path and adjust the Gain [4] down until the
bar graph opens completely.
14. Walk in a wide circle with your back toward the transmitter (about 10 to 15 feet
(3–4.5 m) away).
− Watch the receiver display and listen to the signal. Take note of where the
receiver detects the strongest Signal Strength [10].
− The bar graph will close when the unit detects a signal, and the arrows
will reverse.
− Adjust the Gain [4] down if the bar graph closes completely.
− The Signal Strength [10] numbers on the display will change with the signal
strength (smaller, as you walk away from the target path; larger, as you approach
the target path).
− Make a complete circle around the transmitter. Return to each point in the circle
that the receiver detected.
15. Measure the depth and current of each point to identify the target path. The depth
of the target path should be as expected and the relative current should compare
to the relative current that is alternately flashing with the frequency value on the
transmitter.
Note: The relative current reading will decrease steadily as the locator moves away
from the transmitter. When using higher frequencies, this decline is more evident.
16. Adjust the gain so that the bar graph responds to the target path (open when off
path, almost completely closed when directly over target).
17. Trace the cable/pipe at a slow walk while moving the receiver in a side-to-side
motion, keeping the receiver perpendicular to the ground.
18. Measure the depth and current occasionally to verify target path.
34
78-8130-6150-0 Rev G
Note: In order to measure the depth and current accurately, the operator must
pinpoint the target pipe or cable, and the receiver handle should be in-line with the
target path.
− While in Dir Pk mode, find the highest Signal Strength [10].
− Lower the tip of the receiver to the ground. Twist the receiver left and right
while watching the signal strength.
− When the highest Signal Strength [10] reading is displayed, the handle of the
receiver is in line with the target pipe or cable.
Occasionally, a signal will appear on adjacent cables or pipes. Compare the relative
and actual current readings (value that is under the relative current value and in mA
units) over each path to help determine the target path. Current readings will be
significantly less on the adjacent cable compared to the target path.
19. As tracing proceeds, remember that the most powerful signal is near the transmitter.
As the receiver gets farther away from the transmitter the Signal Strength [10]
decreases. It may be necessary to readjust the gain as needed to ensure that there is
adequate signal for the receiver to operate. Press the Gain [4] up or down when the
Bar Graph [11] is no longer visible (too little signal) or when the Bar Graph [11] is
closed (too much signal).

10. After a fault is located and pinpointed, move the 3M™ Earth Contact Frame about
one Earth Contact Frame width away from the fault and insert it in the ground with
the green-banded leg towards the fault. Compare the numeric signal level with the
fault level reference signal indicated in the lower left box labeled Ref. If the reading
is within 12 dB of the reference signal, the operator has found the major fault. If
the fault reading does not fall within 12 db of the reference signal reading, multiple
faults may exist. The signal level of this secondary fault can be saved by pressing
Fault 1 [SK] or Fault 2 [SK]. The fault with the highest reading will be the primary
fault.

can be configured to send 3M™ iD Marker data directly to some GPS devices. When
an iD marker is located and read, the information read from the iD marker with feature
and attribute data is sent to the GPS device and is stamped with latitude, longitude and
date/time data. The data acquired during this logging process can be uploaded to GIS
mapping software. For more information and detailed instructions pertaining to specific
D. Path Mapping with GPS
The M-Series cable and pipe locators are compatible with hand-held GPS devices and
now have the ability to map the path of underground target facilities. While measuring
the depth to the target, the technician can automatically log the coordinates of the path to
the GPS device. These logged points contain the Trace template that can have valuable
information regarding the facility (owner, utility, size, etc.) and the method used to find
the path (frequency, current, and measured depth).
In order to transmit the path information to a GPS device, the GPS has to have the
ability to accept information on one of its com ports at 4800 Baud. Using the manual
supplied with the GPS device, configure the com port of the GPS to communicate with
the receiver.
If ArcPad™ Software is the mapping software on the mobile device, download the 3M
software application script from the website: www.3M.com/dynatel
With ArcPad™ application installed, the receiver will send the path information (locate
frequency, depth, current, and trace template information) into the software program as a
logged point and can be saved as a .shp file.

1. Creating Trace Templates
The easiest way to create a Trace template is using the 3M™ Dynatel™ PC Tools
Software. The 3M™ Dynatel™ PC Tools software is available free of charge at www.3M.
com/dynatel under the Software section; 2550/2573/2250M/2273M/1420 Locator PC
Tools xx.x.x (EXE xx.xMB).
• Create a TRACE template.
• Save and download the template to the receiver.
Up to four Trace Templates can be stored on the Receiver.
Each Trace template is limited to 132 user editable characters.
The trace template appears in table format: two columns with six lines.
The first column is limited to 8 characters and the second column is limited to 14
characters. In addition to the 132 character table, the receiver will send a sequence
number, the frequency, the measured depth of the conductor, and the current to the GPS.
2. Select Com Port Setting
Menu [6] + Com [SK:3] + GIS [SK] (or PDA [SK])
If the GPS device has the ability to send NMEA coordinates on its com port and has the
ability to receive information at 4800 baud, set the receiver’s com port to GIS.
If the GPS device only has the ability to receive information, set the com port of the
receiver to PDA mode.
Log Prompt = On: Before the receiver returns to locate mode, a verification display
will display on the receiver with the trace template information that will be sent to the
GPS device. This information can be modified and confirmed. Press OK to send to the
GPS device.
Log Prompt = Off: When the receiver returns to locate mode, the trace template and
locate information will be sent automatically to the GPS device.
3. Sending Path Information to GPS Device
1. Establish communication with the GPS device.
2. Set COM port on receiver.
3. Locate target utility.
4. Measure depth to target utility.
− If Log prompt is activated, when the Locate/OK [5] button is pressed (or after a
five second delay), a display will appear that displays the path information.
5. Press Locate/OK [5] to send the information to the GPS device, or Exit to abort the
exchange.
