2.5 SC-600-EUR Signal Clamp (included with UAT-620-EUR, optional for UAT-610-EUR)
In many situations, it is either not possible to gain access to a
cable for making an electrical contact or it is not safe to do so.
The Signal Clamp accessory provides an efficient and safe method
of applying a locate signal to a cable, enabling the Transmitter to
induce a signal through the insulation into the wires or pipes. The
clamp works on low impedance closed circuits only.

3.1 General Tracing Techniques for All Applications
Receiver Locating
1. Turn the Receiver on by pressing the power button for two seconds. Select the desired locating frequency.
Hold the Receiver vertically.
2. Adjust the sensitivity, using the “ /” buttons so that the bar graph reading just begins to show some
movement. The sensitivity control should be at, or close to, maximum sensitivity.
3. Keeping the Receiver vertical and in front of your body, walk across the area to be checked, then follow in a
grid pattern.
Note that there will be no sound from the speaker until the meter reading is above full scale approximately 10%.
Note that objects perpendicular to the receiver will not be detected (white objects in drawings A and B). The
Receiver will detect objects that are parallel or under angle (gray objects in drawings A and B). After performing
the initial grid search as shown in drawing A, repeat grid search at 90 degrees as shown in drawing B.
AA
B
Plan View
4. If at any time the meter reading starts to increase, carefully move the locator forward and back, left to
right to detect the maximum signal. Use the bar graph to help confirm the correct position. If the bar graph
exceeds the maximum value, adjust the sensitivity to bring the reading back within the limits of the bar graph
using “ /” buttons.

12
If the reading is off scale (too great or too small), then pressing the “ / ” buttons together will automatically
adjust the sensitivity to bring the meter deflection to 50%.
5. Rotate the Receiver on its axis to obtain the maximum signal. This indicates that the Receiver is directly over
the line and aligned with the direction of the cable. The direction can also be verified by rotating until the
smallest signal is detected – the Receiver is then perpendicular with the cable/pipe.
100 999 100 999
6. Walk along the path of the cable and trace it by moving the Receiver left to right to find the highest signal.
3.2 Power Mode 50/60 Hz – Passive Location of Energized Cables and Power Lines
Power signals are created by mains power running in the supply cables. These signals are 50 or 60 Hz depending
on the region (for example, Europe has 50 Hz power and the United States has 60 Hz power). This frequency can
be adjusted on the Receiver.
When electrical power is distributed throughout the network, some of the power finds its way back to the power
station via the ground. These stray currents can jump onto pipes and cables and also create power signals.
There must be enough electrical current flowing to create a detectable signal. For instance, a live cable that is not
in use may not radiate a detectable signal. A very well balanced cable (exactly the same current flowing in live
and neutral) will cancel out and may not create a signal. In practice this is unusual as there are usually enough
imbalances in the cable to create a good detectable signal.
1. Turn the Receiver on by pressing the power button for two seconds.
2. Press “ ” button repeatedly until the correct frequency is selected. To change frequency between 50 or 60
Hz refer to the UAT-600-RE Receiver Controls and Display section 2.2.
3. Follow the steps as described in the Receiver Locating section 3.1.
510
3.3 Radio Mode – Passive Location of Utilities
Radio signals are created by low frequency radio transmitter
and are used for broadcasting and communications. They are
positioned throughout the world. As the frequencies are very
low, the signals tend to penetrate and hug the curvature of the
earth. When the signals cross a long conductor such as a pipe or
cable, the signals are re-radiated. It is these re-radiated signals
that can be detected by Radio Mode.
Locating radio signals is very similar to detecting power signals
as they are both passive. With the Radio Mode method, you will
detect metallic utilities, such as pipes, as well as energized and
de-energized cables. Tracing of non-metallic pipes and conduits
will be possible after inserting metal fish tape or cable.

13
1. Turn the Receiver on by pressing the power button for two seconds.
2. Press the “ ” button repeatedly until Radio is selected.
3. Follow the steps as described in the Receiver Locating section 3.1.
The Left/Right arrows are not active during passive location
3.4 Induction Mode – Locating Utilities
Induction Mode is particularly useful for identifying the location of multiple buried utilities before digging.
Induction Mode can be also used for tracing individual cables where there is no access to the line to connect
test leads or a clamp. However, this method may not be reliable if adjacent lines are present because the signal
will be also applied to these lines.
Without the test leads or signal clamp connected to the Transmitter, the Transmitter will automatically start to
radiate a signal around it using an internal antenna. These signals will penetrate the ground and couple onto
buried lines. The signal will then travel along the line which can be detected with the Receiver.
With the Induction Mode method, you will detect metallic utilities, such as pipes, as well as energized and de-energized
cables. Tracing of non-metallic pipes and conduits will be possible after inserting metal fish tape or cable.
Induction Mode – Setting Up the Transmitter
When using Induction Mode, place the Transmitter at least 65 feet (20 m) away from any structure such as
building or a tower to avoid signal interference. Before tracing, take a visual inspection of the area looking for
clues were the buried utility might be present, such as transformers, manholes, street or parking lamps, etc.
The signal will radiate around the Transmitter as well as below it, so it is recommended that when applying a
signal using Induction Mode, a distance of at least 65 feet (20 m) is kept from the Transmitter when pinpointing or
taking depth readings. While locating closer than 65 feet is possible, the operator should be aware that the signal
directly received from the Transmitter may be strong enough to influence the results.
65 ft (20m)
Avoid placing the Transmitter over metallic manhole covers as this will severely reduce the effectiveness of the
Transmitter, and in extreme cases, cause damage to the Transmitter’s circuitry.
1. Turn the Transmitter on by pressing the power button for two seconds.
2. Place the Transmitter over the suspected location of the line, positioning it so that it is along the line.
> 20 m (65 ft)

14
3. Press the “ /” buttons to set the output to level one.
Increase the level if the resulting signal strength is poor.
Increasing the signal unnecessarily may result in the signal
being induced into unwanted lines.
Induction Mode – Locating with the Receiver
1. Turn the Receiver on by pressing the power button for two
seconds.
2. Press “ ” button repeatedly until 33 kHz is selected.
3. Follow the steps as described in the Receiver Locating
section 3.1, using the Left/Right arrow indicators to quickly
assess location of the wire.
4. Optionally measure the depth of the wire. Refer to the
Taking Depth and Current Measurements section 4.3
for details.
For better accuracy, after the initial location of a utility is
detected, move the Transmitter directly over it in case it was
not placed precisely in the beginning of the search.
Where the signal is distorted, the arrows may indicate a different target position than the largest bar graph
reading. In this situation, always use the bar graph to pinpoint the line as it is influenced less than the Left/Right
arrows in a distorted signal field.
500
3.5 Direct Test Leads Connection Mode – Tracing an Individual Pipe or Cable
Direct connection with test leads is the most reliable method to trace individual cable or a pipe.
WARNING
• Only authorized personnel should make connections to cables.
• The Transmitter can be connected to energized wires up to CAT IV 600 V and any de-energized wire or pipe.
• Do not touch metal parts of the connection clips when connecting to the line or when the Transmitter is on
as they may exceed 30 V rms.
• For shielded cables, always connect to the sheath of that cable. The sheath will stop the tracing signal if the
Transmitter is connected to one the internal wires.

15
IMPORTANT NOTICE, PLEASE READ BEFORE TRACING
Avoiding signal cancellation problems with a separate ground connection
The signal generated by the Transmitter creates an electromagnetic field around the wire. This field is what is
detectable by the Receiver. The clearer this signal, the easier it is to trace the wire.
If Transmitter is connected to two adjacent wires on the same circuit (for example, hot and neutral wires
on a Romax cable), the signal travels in one direction through the first wire and then returns (in opposite
direction) through the second. This causes the creation of two electromagnetic fields around each wire with
opposite direction. These opposing fields will partially or completely cancel each other out, making wire
tracing difficult if not impossible.
100
To avoid the cancellation effect, a separate ground connection method should be used. The red test lead of the
Transmitter should be connected to the hot wire of the circuit you wish to trace, and the green/black lead to a
separate ground, such as water pipe, ground stake, metal grounded structure of the building, or outlet ground
connection of an outlet on a different circuit. It is important to understand that an acceptable separate ground
is NOT the grounding terminal of any receptacle on the same circuit as the wire you wish to trace. If hot wire is
Energized and the Transmitter is properly connected to a separate ground, the red LED on the Transmitter will
light up. The separate ground connection creates maximum signal strength because the electromagnetic field
created around the hot wire is not being cancelled by a signal on the return path flowing along an adjacent
wire (ground or neutral) in the opposite direction, but rather through the separate ground circuit.

Direct Test Leads Connection Mode – Setting Up the Transmitter
1. Turn the Transmitter on by pressing the power button for two seconds.
2. Connect the black and red test leads to the Transmitter inputs. The Transmitter will switch automatically to
Direct Connection Mode and the display will show the direct connection icon .
3. Insert the ground stake into the ground a few meters perpendicular to the line. Connect the black lead to
the ground stake with an alligator clip.
4. Connect the red test lead to the target line. If line is energized above 30 V the red warning LED will illuminate.
5. Press the button repeatedly to select 8 kHz frequency (preferred for most tracing situations) or 33 kHz.
Refer to section 4.1 When to Use 8 kHz vs. 33 kHz Frequency for more information. Frequencies “A-Lo” and
“A-Hi” are used with optional A-Frame Ground Fault Locator accessory used to pinpoint ground faults and
are described later in the manual.
6. Press the “ /” buttons to set the output to level one. Increase the level if the resulting signal strength
is poor. Increasing the signal unnecessarily may result in the signal “bleeding off” onto other services and
creating misleading “ghost” signals. It will also drain more power from the battery.
Note: When connected, the Transmitter will emit a beep tone. The better the connection to the line and
ground, the faster the beep tone will be. Check for a good connection by disconnecting and then reconnecting
the red lead. It is also possible to check the signal current being supplied by the Transmitter by entering the
Settings Menu and selecting the mA option.
Things that can affect the quality of connection are a rusty pipe connection point (clean the connection area
with a wire brush) or poor grounding. To improve the connection quality due to poor grounding, try inserting
the stake into damp ground. If necessary, dampen the surrounding ground with water. If grounding is still an
issue, try connecting test lead to a manhole cover surround. Avoid connecting to fence railings as these may
create return signal currents along the fencing that will interfere with the locating signal.
Note: If the signal level bars do not fill, this indicates that the impedance of the line is limiting the current
output. Increasing the output beyond this point will not increase the signal. If more signal is required, check
the quality of the connection to the line and ground.
When connecting to large diameter pipes and cables, it is sometimes not possible to find a suitable projection
to apply the alligator clip. If the material is ferrous, use a magnet to make contact to the line and then attach
the alligator clip to a magnet. For example: making a connection to a street lighting circuit. Usually it is
practice to connect the sheath of a lighting cable to the metallic inspection cover of a street lamp. Making a
connection to the inspection plate will induce a signal to the cable via the plate and sheath. Usually, there is
no projection on the plate on which to clip so using a magnet on the plate provides a suitable clipping point.
Direct Test Leads Connection Mode – Locating with the Receiver
1. Turn the Receiver on by pressing the power button for two
seconds.
2. Match the frequency of the Transmitter by pressing the
“” button repeatedly. Select either 8 kHz or 33 kHz
depending on the Transmitter setup.
3. Follow the steps as described in the Receiver Locating section 3.1.
4. Use the Left/Right arrow indicators to quickly assess location of
the wire.
5. Optionally measure the depth of the wire. Refer to the Taking
Depth and Current Measurements section 4.3 for details.
