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.

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.
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.
100 100 999999
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-R Receiver Controls and Display section 2.2.
3. Follow the steps as described in the Receiver Locating section 3.1.
www.GlobalTestSupply.com

12
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.
510
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.
> 65 ft (20 m)
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.

13
> 65 ft (20 m)
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 perpendicular to the line.
3. Press the Signal button to switch between Hi and Lo signal strength. Lo signal level uses less energy and helps to
preserve batteries. 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.

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 ONLY to de-energized wires or pipes.
• 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 of the internal wires.

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 gray test lead of the
Transmitter should be connected to the hot wire of the circuit you wish to trace, and the green 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.

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 green and gray test leads to the Transmitter inputs. The Transmitter will switch automatically to
Direct Connection Mode.
3. Insert the ground stake into the ground a few meters perpendicular to the line. Connect the green lead to the
ground stake with an alligator clip.
4. Connect the gray test lead to the target line. If connecting to the electrical cable, make sure the wires are
de-energized.
5. Press the Signal button to switch between Hi and Lo signal strength. Lo signal level uses less energy and helps
to preserve batteries. 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
lower the tone will be. Check for a good connection by disconnecting and then reconnecting the gray lead.
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.
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. Normally, 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 33 kHz frequency.
Note: 8 kHz frequency is not used for connection with
UAT-500-T Transmitter. This frequency is provided to support
optional UAT-600-T Transmitter.
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

3.6 Signal Clamp Accessory – Tracing an Individual Pipe or Cable
500
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 provides an efficient and safe method of applying a locate signal to a cable.
When using the Signal Clamp, it is best if both ends of the target cable are grounded to enable the current to flow.
When applying a clamp close to a grounding point where multiple grounds or a grounding bus exists, ensure that the
clamp is placed around the target line and not to the ground bus/other grounds to reduce the effects of the transmitted
signal also being applied to an unwanted line.
Signal Clamp Accessory – 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 of the Signal Clamp to the Transmitter inputs.
3. Clamp the Signal Clamp around the target line.
4. Press Signal button to switch between Hi and Lo signal strength. Lo signal level uses less energy and helps to

result in the signal “bleeding off” onto other services and creating misleading “ghost” signals. It will also drain
more power from the battery.
