Introduction
Congratulations! You have just purchased one of the nest, most
advanced locating devices available today! When you choose a
quality 3M™Dynatel™Advanced Pipe/Cable Locator 2220M, you
get outstanding performance andreliability.
The 2220M locator with the 3-watt transmitter is an excellent
instrument for tracing underground utilities. The 2220M provides
one audio frequency for locating long sections of cable and one radio
frequency for tracing pipes that may have high resistance insulators
and rubber gaskets that are often found in water and gas distribution
systems. The 2220M also provides three sonde locating frequencies.
The 2220M locator with the 12-watt transmitter* option oers
additional power output levels for improved induction performance,
8K (low frequency) induction for shallow facilities, such as risers, and
an ohm-meter function for measuring path resistance.
* Output Power up to 12 Watts for the 12 Watt Transmitter is achieved using the supplied
external power source. 12 Watt Output Power varies by frequency, or is limited to 1 Watt
at 82 kHz on the U-Model using direct connection method.

Transmitter Operations
There are three dierent methods of applying the transmitter’s locating
signal to the target conductor: Direct Connection, 3M™Dynatel™ Dyna-
Coupler Clamp, and Induction.
Direct Connection
This is the preferred mode of operation because the transmitter
is connected directly to a metallic portion of the target conductor
(hydrant, meter, riser, valve, sheath, or tracer wire).
1. While the transmitter is o, plug the direct connect cable into the
output jack of the transmitter.
2. Attach the red lead of the direct connect cable to the target
conductor.
3. Extend the black lead as far as possible from the target conductor
at a right angle (90 degrees) to the suspected path of the target.
4. Insert the external ground rod and attach the black lead of the
transmitter.
5. Turn the transmitter ON by pressing the frequency button. Select 8
kHz, 82 kHz, or both (the word ALL will be displayed).
6. An audible tone, indicating the continuity of the signal path will
sound for 10 seconds and the output current will display in mA.
a. Solid tone = Good signal
b. Fast Beep = Moderate signal
c. Slow Beep = Minimal signal
d. No tone = Poor signal
7. The frequency will ash alternately with the current of the target
conductor on the display.
8. Trace the signal path with the receiver.

14 78-9000-0021-3-DNovember 2016
3M™Dynatel™Dyna-Coupler Clamp
If a direct connection to the target facility is not possible, use the
Dyna-Coupler clamp to apply the locating frequency on the metallic
target conductor. In order to trace a target using this method, both
ends of the target must be well grounded.
1. While the transmitter is o, attach the coupler cable to the
Dyna-Coupler clamp and plug it into the output jack of the
transmitter.
2. Clamp the Dyna-coupler around the metallic target. The jaws of the
coupler must be fully closed.
3. Select 8 kHz or 82 kHz on the transmitter by pressing the
frequency key.
4. Select High Output level when using a 3-watt transmitter, or High
Output or Max Output level when using a 12-watt transmitter, for
the best signal-to-noise ratio.
5. Trace the signal path with the receiver.

1578-9000-0021-3-D November 2016
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 eld. 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.
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 frequency key.
5. Select high output level when using a 3-watt transmitter, or high
output or max output level when using a 12-watt transmitter, for the
best signal-to-noise ratio.
6. 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 eld of the transmitter.
This mode is indicated by the induction icon in the bottom left-hand
corner of the receiver's locate screen.
Note: If nothing is plugged into the output jack of the transmitter, the transmitter
will automatically turn on the internal antennae, and 82 kHz will broadcast
in induction mode. For best results, the receiver should be at least 25 feet
(7.6 m) away from the transmitter to begin tracing the target path. Attempt-
ing to trace the target close to the transmitter may lead to false indications
due to the receiver detecting the large magnetic eld radiating from
the transmitter.
