Transmitter Operations
There are three different 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 off, plug the direct connect cable into the output 
jack of the...

13
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 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...

Pipe and Cable Locating
1. Press the ON /OFF key.
2.  Press the LINE key to match the frequency that the transmitter is sending.
3.    Sweep the receiver across the area in a left right motion, while watching the 
bar graph, directional arrows, and signal strength.
4.    When a magnetic field is detected, the bar graph will close, the signal 
strength and the audio will increase.
5.    Adjust the gain so that the bar graph opens when the receiver is not on target 
and closes when directly over it by...

Sonde Locating
A sonde is a small transmitter that enables the user to trace metallic and 
nonmetallic pipes, sewers, drains, or ducts. It can also be used to find a blockage 
or collapse. Refer to sonde manufacturer’s guide for proper selection of sonde 
for the desired application.
A representation of a sonde transmission field appears below.
There are typically three peak signals present. The strongest peak signal is over 
the center of the sonde. The signal will drop off each ‘side’ or ‘end’ of...

Pin-Pointing the Sonde
Note: The receiver handle must be oriented perpendicular to the sonde. 
The cross bar of the receiver must be in line with the sonde (the opposite 
of line locating) .
1.   Set the receiver to sonde mode by pressing the SONDE key until the 
frequency of the sonde appears on the locate screen.
2.    Holding the receiver perpendicular to the suspected path, walk the path until 
the receiver detects the first peak signal of the sonde.
3.  Adjust the gain down if the bar graph...
