Congratulations! You have just purchased one of the finest, most advanced locating 
devices available today!
The 3M
™ Dynatel™ Cable/Pipe/Fault Locators 2250M-iD/2273M-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 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 2250M-iD/2273M-iD will also search for two different types of utility markers 
simultaneously. When used in conjunction with a hand-held GPS device 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. 
The 2250M/2273M Series transmitters are available in 3-watt, 5-watt and 12-watt units. 
12 watts for the 12-watt transmitter, or 5 watts for the 5-watt transmitter, is attained by 
utilizing the Cigarette Lighter Adapter or External Rechargeable Battery (2200RB).
3M is dedicated to bringing you premium equipment with outstanding reliability, backed 
by one of the best warranties in the business and outstanding service.
Visit our website at www.3M.com/dynatel  for more application notes and product 
information.

1. Safety Information
Please read, understand and follow all safety information contained in these instructions 
prior to the use of the 3M™ Dynatel™ Cable/Pipe/Fault Advanced M-Series Locator. 
Retain these instructions for future reference.
A.  Intended Use
The 3M Dynatel Cable/Pipe/Fault Advanced M-Series Locator is used to identify the 
placement of underground utility lines. The system must be installed as specified in 
the 3M Dynatel Cable/Pipe/Fault Advanced Locator 2250M/2273M Series Operator 
Manual. It has not been evaluated for other uses or locations. If this equipment is used 
in a manner not specified by 3M, the protections provided by the equipment may be 
impaired.
Explanation of Signal Word Consequences
! Warning: Indicates hazardous situation which if not avoided, could result in 
death or serious injury.
! Caution: Indicates hazardous situation which if not avoided, could result in 
minor or moderate injury.
Explanation of Product Safety Label Symbols
Do not throw away in normal trash.
FWarning: Risk of electric shock
!
 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. 
						

							78-8130-6150-0 Rev G 7
! 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.
2.  About This Manual
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 3M
TM 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 
from the illustrations  shown.

3. Quick Start
A.  Transmitter Battery Installation
Loosen the six screws on the battery compartment cover on the bottom of the transmitter. 
Remove the cover.
Install six ‘C’ size alkaline cell batteries (LR14) into the compartment as indicated by 
the polarity symbols (+ and –).
Replace the cover and tighten the screws.
Press and hold OFF [T-1] to manually test the batteries. The display and audio will 
indicate one of the following levels: (OK w/solid tone = good; LO w/beeping tone = 
low; "--" w/no tone = replace)
! Caution
To reduce the risks associated with fire and explosion:
•  Do not short, excessively heat, or dispose of batteries in fire.
•  Install batteries with proper polarity.
•  Use only Alkaline "C" (LR14) sized batteries.
•  Do not charge batteries
•  Do not use leaking batteries
To reduce the risks associated with environmental contamination:
•   Dispose of batteries and electronic components in accordance with all regulations.
•  Ensure batteries are installed with correct polarity.
•  Always remove batteries when storing the units for long periods of time. 6 'C' (LR14) size

[T-1] off: Turns unit off and performs battery test.
[T-2] on: Ohm-meter / Tone: Turns the unit on and cycles through the following 
commands when pressed repeatedly.
 Ohm-meter:  Measures the continuity of the trace conductor/pipe and its far-end 
ground. It is also used to measure the fault resistance to earth. 
Tone:  In the tone mode, the transmitter generates 577 Hz and 200 kHz signals.
[T-3] on: Trace (frequency): Turns the unit on and places the unit in Trace mode.   Select  Frequency:  Press Trace [T-3] repeatedly to cycle through the transmitter’s 
active frequencies (577 Hz, 8 kHz, 33 kHz, and 200 kHz). The selected frequency 
will be displayed [T-4]. ‘ALL' indicates that the following active frequencies are 
transmitting simultaneously: 577 Hz, 8 kHz, 33 kHz, and 200 kHz.
[T-4] Digital Display:    Indicator Flags: These flags coincide with the operational mode of the transmitter. 
(From top left to bottom right) Trace mode [T-3], Tone mode [T-2], Ohm-meter [T-2], 
Voltage (at start up the transmitter checks for foreign voltage), and the Output Level 
Flag (no flag = normal output; flag = high output; flashing flag = maximum  output).
Digital Display: Indicates frequency, relative current, resistance, battery level and 
voltage (if present on target).
[T-5] Output Level: Cycles output level; normal, high and maximum. Normal=No Flag; High=Flag; Maximum=Flashing Flag (indicated in Digital Display 
[T-4])
NOTE: An external 12-volt power source is required to obtain Max Output level (12 
watts for 12-watt transmitters and 5 watts for 5-watt transmitters).
