Locating pipes and cables
For more detailed descriptions of using the
locator and transmitter, and for detailed
locate techniques, refer to the Operation
Manual.
The RD7100 locator is designed to operate
with the ‘blade’ of the locator perpendicular
to the path of the cable or pipe being
located.
Running a Self-Test
We recommend that a Self-Test is run at least weekly, or before each use. As the Self-
Test tests the integrity of the locate circuity, it is important that it is carried out away from
larger metallic object such as vehicles, or strong electrical signals. To run a Self-Test:
1. Press the key to enter the menu.
2. Scroll to the INFO menu using the or arrows.
3. Press the key to enter the INFO menu.
4. Select TEST using the or arrows.
5. Press the key to select YES
6. Press the key to begin the Self-Test
7. Once the Self-Test is completed, the result (PASS or FAIL) will be displayed.
8. Restart the locator using the key
SideStepauto™
The transmitter can be used to recommend a general-purpose locate frequency for the
intended locate task by measuring the impedance of the target cable or pipe. To run
SideStepauto™, connect the transmitter to the target utility, then:
1. Press the key to enter the menu.
2. Scroll to the OPT F menu using the or arrows.
3. Press the key to select ‘START.
4. Press the key to start the test. The transmitter will automatically select a general
purpose frequency for use on the connected utility.

15
ENGLISH
Locating with Active Frequencies
Active frequencies are applied to the target pipe or cable using the transmitter, and
provide the most effective way of tracing buried pipes or cables.
Generally speaking, it is better to use a low frequency on larger, low impedance utilities,
and move to a higher frequency on smaller, high impedance utilities.
The lowest power setting required to trace the target utility should always be used to
minimize the risk of false trails.
The transmitter can apply a signal using three different methods:
Direct connection
In direct connection, you connect the transmitter directly to the pipe or cable you wish to
survey using the red Direct Connect lead supplied. The black lead is generally connected
to earth using the supplied ground stake.
The transmitter will then apply a discrete signal to the line, which you can trace using the
locator. This method provides the best signal on an individual line and enables the use of
lower frequencies, which can be traced for longer distances.
WARNING! Direct connection to live conductors is POTENTIALLY LETHAL. Direct
connections to live conductors should be attempted by fully qualified personnel only
using the relevant products that allow connections to energized lines.
Induction
The transmitter is placed on the ground over or near the survey area. You select the
appropriate frequency. The transmitter will then induce the signal indiscriminately to
any nearby metallic conductor. In induction mode, using higher frequencies is generally
recommended as they are induced more easily onto nearby conductors.
Transmitter Clamp
An optional signal clamp can be placed around an insulated live wire or pipe up to
8.5"/215mm in diameter to transfer the transmitter signal to the utility. This method of
applying the transmitter signal is particularly useful on insulated live wires and removes
the need to disconnect the supply to the cable.
WARNING! Do not clamp around uninsulated live conductors.
WARNING! Before applying or removing the clamp around a power cable ensure
that the clamp is connected to the transmitter at all times.
Locating with Passive Frequencies
Passive frequency detection takes advantage of signals that are already present on
buried metallic conductors. The RD7100 supports up to three types of passive
frequencies: Power, Radio and CPS* signals. You can detect these frequencies without
the aid of the transmitter.
*Model specific.

16
Power Filters
RD7100PL and PLG locators allows operators to take advantage of the harmonic signals
found on power networks. Once in Power Mode, press the key to switch out of
Radiodetection’s sensitive Power Mode and scroll through five individual Power Filters.
This enables operators to establish if a single large power signal comes from one source
or from the presence of multiple cables. The different harmonic characteristics of the
detected lines can then be used to trace and mark their route.
Additionally the use of an individual harmonic can allow you to locate power lines in
situations where the total signal would otherwise be too large.
Locate Modes
Dependent on the model selected, the RD7100 offers a choice of up to 4 locate modes,
each of which is designed for specific uses, depending on what task is being carried out.
To scroll between locate modes, press the key.
PEAK: For accurate locating, the peak bargraph provides a visual readout of the
signal strength. The peak signal is found directly over the buried utility.
PEAK+: Choose to combine the accuracy of the Peak bargraph with Null arrows,
which can indicate the presence of distortion, or with proportional Guidance
arrows for rapid line tracing – switch between them by holding the key.
GUIDANCE: Proportional arrows and a ballistic ‘needle’ combine with audio
left/right indication for rapidly tracing the general path of a buried utility.
NULL: Provides a quick left/right indication of the path of a utility. As Null is
susceptible to interference, it is best used in areas where no other utilities
are present.
Depth, current and compass readouts
WARNING! Never use the depth measurement readout as a guide for
mechanical or other digging activity. Always follow safe digging guidelines.
The RD7100 locator can measure and display the utility depth, locate signal current and
the relative orientation of the cable or pipe to the locator. This helps you to make sure that
you are following the right cable or pipe, especially when other utilities are present.
The RD7100 locator features TruDepth™, a feature that helps you to ensure the accuracy
of your locates. The depth and current are automatically removed from the display when
the locator is at an angle of more than 7.5° from the path of the cable or pipe being
located, or when the locator determines that signal conditions are too poor for reliable
measurements.

17
ENGLISH
Using accessories
The locator and transmitter are compatible with a wide range of accessories. For detailed
information on using any of the accessories below please refer to the RD7100 locator
operation manual.
Transmitter signal clamps
When it is not possible to connect directly onto a pipe or cable, or induction mode is
unsuitable, a transmitter signal clamp may be used. The clamp is plugged into the output
of the transmitter and provides a means of applying a locate signal to an insulated live wire.
This is particularly useful with live insulated cables as it removes the need to disable the
power and break the line.
WARNING! Do not clamp around uninsulated live conductors.
WARNING! Before applying or removing the clamp around a power cable
ensure that the clamp is connected to the transmitter at all times.
To locate or identify individual lines a locator signal clamp can be connected to the
accessory socket of the locator and can be clamped around individual pipes or cables.
Stethoscopes and locator signal clamps
Locator clamps can be used to identify a target cable or pipe amongst a number of
different cables by checking for the strongest locate signal. When cables are bunched or
tightly packed, a stethoscope antenna can be used in place of a clamp.
To use a stethoscope or locator signal clamp, connect it to the locator’s accessory socket.
The locator will automatically detect the device and filter out location modes that are
irrelevant.
Sondes, Flexrods and FlexiTrace
Sondes are battery powered transmitters that are useful for tracing non-metallic pipes.
They can be fixed to Flexrods to allow them to be pushed through pipes or conduits, and
some are suitable for blowing through ductwork. Some models of the RD7100 can detect
a range of sonde frequencies, including those transmitted by flexiprobe™P540c pushrod
systems and P550c flexitrax™crawlers.
For a detailed guide on locating sondes, please refer to the operation manual.
A FlexiTrace is a traceable fiberglass rod incorporating wire conductors with a sonde
at the end. It is connected to the output of the transmitter and is typically used in small
diameter, non-metallic pipes. The user has the option of locating the entire length of the
cable or choosing to locate only the tip of the cable.
The FlexiTrace has a maximum power rating of 1W. When using the FlexiTrace with a
Radiodetection Tx-5 or Tx-10 transmitter, the output limit must be set to 1W in the MAX P
menu and the output voltage limit set to LOW in the MAX V menu.
No additional settings are required for the Tx-1 transmitter.

18
Fault-finding with an A-Frame
The RD7100PL, PLG, TL and TLG models have the ability to detect cable or pipe
insulation faults accurately using an A-Frame accessory. The Tx-5 and Tx-10 transmitters
provide fault finding signals that can be detected by the A-Frame as a result of the signal
bleeding to ground through damaged cable sheaths.
The Transmitter’s multimeter function can be used to measure the impedance of the
connected pipe or cable in order to characterize the fault.
For a detailed guide to fault-finding, please refer to the operation manual.
Plug / Live cable connector
The plug connector is connected to the output of the transmitter and is used to put a
signal onto a line and trace it from a domestic mains plug to the service cable in the
street.
The live cable connector can be used to apply a signal to a live cable. Only suitably
qualified personnel should use this equipment.
Submersible antenna
This antenna is connected to the locator and used to locate pipes and cables underwater
at depths of up to 300 feet / 100 meters.
WARNING: use of the submersible antenna should be by fully licensed and
experienced personnel only, and only after fully reading the operation manual!
RD Manager PC Software
RD Manager is the RD7100 locator system PC companion, and it allows you to manage
and customize your locator. RD Manager is also used to retrieve and analyze survey and
usage data, run an eCert calibration, and to perform software upgrades.
You can use RD Manager to register your products to obtain an extended warranty, setup
your locator by performing a number of maintenance tasks such adjusting date and time,
activating and de-activating active frequencies, or by setting-up functions like CALSafe
or StrikeAlert.
RD Manager is compatible with PCs running Microsoft Windows 64 bit operating system.

Automatic Usage-Logging
RD7100 locator models equipped with GPS offer a powerful data logging system which
records all the instrument’s critical parameters (including GPS position, if available) and
warnings in its internal memory every second.
The automatic logging system is always active and cannot be disabled. The locator’s
memory is capable of storing over 500 days of usage data, when used for 8 hours per day.
Logs can be retrieved using the RD Manager PC application for usage analysis and
survey validation. Refer to the RD Manager operation manual for further information.
GPS
The RD7100 locator can use an internal GPS module (GPS models only) to be able to
detect and store its latitude, longitude and accurate UTC time alongside its location data.
This positional information is then appended to the automatic usage-logging system.
The presence of GPS data allows for the data to be mapped easily and to export and
save the information directly into GIS systems.
GPS menu settings
There are 5 options in the GPS menu:
• INT: Select this to use the internal GPS if present.
• OFF: Select this to switch off the internal GPS module and save battery.
• SBAS: Set SBAS (Satellite-based augmentation systems) mode to improve GPS
