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
20
78-8130-6151-8 Rev G
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 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 or maximum
power output 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 Digital 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.
Note that the number that flashes alternately with the selected frequency is called
the relative current. This number can be useful in identifying the target cable/
pipe and is discussed more in 8. Depth and Current Estimate and 10. Locating in
Directional Peak Mode.
4.
Press Output Level [T-5] to select high or maximum power output level for longer
tracing distances or deep pipe/cable.
B. 3M™ 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 Dyna-Couplers - Part numbers 3019, 4519,
1196/C
A potential for electrical shock exists when using the Dyna-Coupler on cables energized with
electrical power. Use appropriate safety procedures.
DO NOT USE ON CABLES CARRYING IN EXCESS OF 600 VOLTS RMS.
78-8130-6151-8 Rev G
21
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 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 or maximum output power level
by pressing the Output Level key [T-5] on the transmitter.
C. Induction Method
Near-end ground
Transmitter
Hinge
Far-end ground
Suspected Cable Path
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
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 levels.
Higher induction outputs are needed for detecting deeper depths and longer ranges.
The 3M Dynatel™ Advanced Locator 2200M Series 3 Watt transmitters provides
two induction frequencies: 33 kHz and 133 kHz. The 12 Watt transmitter provides
three induction frequencies: 8 kHz, 33 kHz and 133 kHz. The 133 kHz frequency is
22
78-8130-6151-8 Rev G
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.
−− Align the Induction Direction arrows on the transmitter with the target
conductor.
• Turn on the transmitter, select the frequency and select high output or max output
level for best signal-to-noise ratio.
• Trace the signal path with the receiver using the Induction Peak mode.
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.
Use Induction Peak mode when sweeping distance between the transmitter and receiver
is 7.6–20 m (25–60 feet). Beyond 20 m (60 feet) you can also use the Special (single)
Peak or Directional Peak modes. Special (single) Peak 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.
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 133 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 7.6 m (25 feet) 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™ Advanced 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
78-8130-6151-8 Rev G
23
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™ Advanced Locator 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. Dynatel transmitters provide a choice of induction frequencies and
output levels. Higher induction outputs are needed for detecting deeper depths and
longer ranges. The Dynatel 2200M Series 3 Watt transmitters provides two induction
frequencies: 33 kHz and 133 kHz. The 12 Watt transmitter provides three induction
frequencies: 8 kHz, 33 kHz and 133 kHz. The 133 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 Peak 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 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
24
78-8130-6151-8 Rev G
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 multidirectional 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 (133 kHz) and highest output level.
• Select the Induction Peak (IndPk) mode and 133 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
mode is a newly added locate mode for use in closer proximity to a transmitter in
Induction mode (<60 ft , 20 m typically). Special (single) Peak would give the highest
sensitivity, but is affected by the air signal more than Induction Peak mode.
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 (133 kHz), or medium frequency (33 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.
78-8130-6151-8 Rev G
25
• Select the Induction Peak (IndPk) mode, and press the Gain (+ or -) 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 7.6 m (25 feet) 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 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 mode when sweeping
distance between the transmitter and receiver is 7.6–20 m (25–60 feet). Beyond 20 m
(60 feet) you can also use the Special (single) Peak or Directional Peak modes.
• Special (single) Peak 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)
In Dir Pk 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
strength value to locate the exact target path.
Left of Target Path
Directly Over Target Path
26
Right of Target Path
78-8130-6151-8 Rev G
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.
B. Directional Null (DirNull)
In DirNull mode, as the operator approaches the cable or pipe, the numerical signal
strength 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.
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
handle.
Before marking target path, always use directional peak or special peak mode to verify
location.
78-8130-6151-8 Rev G
27
C. Special Peak (Spl Pk)
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
D. Induction Peak (Ind Pk)
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, 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

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.
−− 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 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.
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 screen, press Save [SK]. The
screen and memory location will populate
with the current information.

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.
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
unit 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 is no longer visible (too little signal) or when the bar graph is closed (too
much signal).
20. Trace the path until you reach a logical termination point (i.e.: terminal, meter,
cabinet, etc).

Transmitter Signal
Ground Fault location
8.
When the bar graph fills toward the left (red-and-white-striped Fault Finding
Direction Indicator [13] (See illustration above.)) side of the display, the fault has
been passed and is now behind the operator. Move back, inserting the Earth Contact
Frame every few inches, until the arrows alternate back to green. Mark the point
beneath the center of the Earth Contact Frame. Turn the Earth Contact Frame 90
degrees and insert into the ground over the previously marked point. Move the
Earth Contact Frame to the left and right (following the directions of the green and
red indicator arrows). When the arrows reverse a third time, turn the Earth Contact
Frame 90 degrees again. Pinpoint the fault by moving the Earth Contact Frame in
the direction of the green and red arrows. The fault is located beneath the center of
the Earth Contact Frame when the arrows change from one side to the other this
time.
36
78-8130-6151-8 Rev G
9.
To verify the fault location, insert the 3M™ Earth Contact Frame’s red-and-whitestriped probe directly on the spot identified above. Pivot the Earth Contact Frame
in a circle around the red-and-white-striped leg re-inserting the green-banded leg
in the ground every few degrees of the circle (See illustration below.). The arrow
should always point toward the left (red) indicating that the fault is directly below
the red-and-white-striped leg.
10. After a fault is located and pinpointed, move the 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.

18. GPS Operation
A. Communicating with the GPS Device
The COM Setup [SK:3] display will toggle through several options to configure the
Serial Port [15] ([14] on 3M™ Dynatel™ Advanced Locator 2250M Receiver) of the
receiver (depending on the application, or capabilities of the GPS device). Select from
the following options.
NMEA – The Serial Port is configured to receive NMEA signals from a GPS device
(4800 Baud Rate). (Capture Mode/Mode 1)
GIS – The Serial Port is configured to send data to and receive data from a GPS device
that has GIS mapping capabilities. (Capture/Transmit Mode/ Mode2)
PC – The Serial Port is configured to communicate with a computer for the Dynatel PC
Tool Kit application.
PDA – The Serial Port is configured to only send information if the GPS device only has
the ability to receive information.
TRSync - Serial Port is configured in PDA mode but the data is transmitted in an
abbreviated .CSV (Comma Separated Value) format
Log Prompt = On – Before the receiver returns to locate mode, a verification screen
will pop up on the receiver display asking if you want to log this point. Press OK to send
data to the GPS device.
Log Prompt = Off – When the receiver returns to locate mode, the marker locate
information will be sent automatically to the GPS device.
78-8130-6151-8 Rev G
51
B. Capturing the GPS Coordinates
(Capture Mode / Mode 1)
If the GPS device is not configured properly, there is an error communicating with the
receiver, or the GPS has not acquired enough satellites to pinpoint the location, the
receiver will display the message “Insert External Device”.
When the receiver is communicating with a GPS
device, the LAT and LONG coordinates received
from the GPS device will appear on the marker
locate screen.
1.
Locate a marker (See Single Marker Locate, Section 13D.)
2.
Press Read [SK]
The information from the 3M™ iD Marker, as well as the GPS coordinates, will display
on the receiver display. This information is saved automatically in the Read Marker
History. (See Reviewing Marker Read/Write History, Section 17.)
If the marker is a passive marker (rather than iD) the receiver will display “No iD
Marker Found”. The GPS coordinates of the attempt to read the non-iD marker are
stored in the Read Marker History as serial number # 0000-0000-0000. The marker
details will indicate “not an iD marker”, but will display the GPS coordinates.
C. Sending 3M iD Marker Data to GPS
(Capture-Transmit Mode / Mode 2)
Receivers that have marker locating capability (indicated by ‘iD’ in the model number)
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
GPS devices, refer to www.3M.com/dynatel for GPS instruction sheet.
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.
52
78-8130-6151-8 Rev G
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

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
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 screen
will pop up 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 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.
