Congratulations! You have just purchased one of the finest, most advanced locating
devices available today!
™
The 3M
Dynatel™ Cable/Pipe/Fault Locators 2250ME-iD/2273ME-iD are designed
with all of the functionality of previous Dynatel models, and iD versions have the
enhanced capability to read and write user information into the 3M EMS iD markers.
Information such as a pre-programmed identification number, facility data, application
type, placement date and other details can all be read, stored and downloaded to your
PC for enhanced resource management with this revolutionary equipment. The Dynatel
Cable/Pipe/Fault Locators 2250ME-iD/2273ME-iD will also search for two different
types of utility markers simultaneously. When used in conjunction with a hand-held
GPS the ability to transmit path and marker coordinates multiplies the potential to
the mapping industry. This equipment provides a simple system for mapping utility
information directly into CAD and GIS systems.
3M is dedicated to bringing you premium equipment with outstanding reliability, backed
by one of the best warranties in the business and outstanding service.

To reduce the risk associated with hazardous voltage:
• Potential for electric shock exists when handling connection cables while the transmitter is
ON. Make all connections prior to powering on the unit. Turn transmitter OFF before handling
connection cables.
• Voltage greater than 240 volts will damage equipment and could cause personal injury or
death. Make all connections before turning on the transmitter. Follow standard procedures
for reducing the voltage.
• Do not change or modify this product in any way.
Rechargeable Battery
The 3M Dynatel Sealed Gel-Cell Battery 2200RB can be used as an auxiliary battery
in 3M™ Dynatel™ 2200 Series Transmitters. It plugs into the external jack [T-7] and

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.
78-8130-6151-8-E 15
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 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.
