Important notices
General
The performance of any cable and pipe locator may be
affected when used in close proximity to ferrous materials
such as manhole covers, steel-toe boots and nearby
vehicles. Keep a distance of one or two meters from
these objects when taking critical measurements such as
depth and current readings.
This instrument, or family of instruments, will not be
permanently damaged by reasonable electrostatic
discharge and has been tested in accordance with IEC
61000-4-2:1995. However, in extreme cases temporary
malfunction may occur. If this happens, switch off, wait
and switch on again. If the instrument still malfunctions,
disconnect the batteries for a few seconds.
Safety
This equipment shall be used by fully qualied and trained
personnel only.
Radiodetection locators detect almost all buried cables
and most conductors, but there are some which do not
radiate signals and which Radiodetection locators cannot
detect. Radiodetection locators do not indicate whether
a signal is from a single cable, several buried side by side
or one above another. Exercise caution and due diligence
when conducting any survey.
Making a direct connection to live power lines is
extremely dangerous to life. Do not attempt any direct
connection unless you are fully trained and qualied
to do so.
WARNING! The transmitter is capable of
outputting potentially lethal voltages. Take care when
applying signals to any pipe or cable and be sure to
notify other technicians who may be working on the
line.
WARNING! Reduce audio level before using
headphones to avoid damaging your hearing.
WARNING! This equipment is NOT approved for
use in areas where hazardous gases may be present.
WARNING! When using the transmitter, switch off
the unit and disconnect cables before removing the
battery pack.
WARNING! The RD7000+ will detect almost all
buried conductors but there are some objects that
do not radiate any detectable signal. The RD7000+,
or any other electromagnetic locator, cannot detect
these objects so proceed with caution. There are
also some live cables which the RD7000+ will not be
able to detect in Power mode. The RD7000+ does
not indicate whether a signal is from a single cable or
from several in close proximity.
Batteries
WARNING! Batteries can get hot after prolonged
use at full output power. Take care while replacing or
handling the batteries.
Battery disposal
Batteries should be disposed of in accordance with your
company’s work practice, and/or the relevant laws or
guidelines in your country or municipality.

Section 3 – Basic operation
3.1 Starting the system
The locator and transmitter are battery powered. Install
good quality D-cell (LR20) NiMH or Alkaline batteries
into the locator and transmitter battery compartments
or install the appropriate rechargeable battery pack.
Alternatively, you can power the transmitter from a mains
or vehicle power source using a Radiodetection supplied
adapter.
To switch the locator or the transmitter on, press and hold
the keypad Power Key for two seconds. When you switch
the system on it will perform an LCD segment check.
It will then display the model number followed by the

to contact Radiodetection technical support or update
your locator to the latest software.
NOTE: Once the system is switched on, pressing the
Power Key momentarily will activate the locator or
transmitter menu.
3.1.1 D-cell (LR20) Batteries
The LCD provides a battery level indicator (refer to
the diagrams in Sections 2.1 and 2.2). When battery
replacement is necessary, the LCD shows a ashing
battery icon. The expected alkaline battery life under
normal working conditions is approximately 30 hours on
the locator and 15 hours on the transmitter.
NOTE: Prolonged use of high power output on the
transmitter will reduce battery life.
To replace the batteries on the locator, unlatch the
battery compartment cover, which is located above
the accessory panel, and lower the tray. Remove the
spent batteries and insert two D-Cell Alkaline or Ni-Cad
batteries.
To replace the batteries on the transmitter, unlatch the
accessory tray. The battery compartment is located
underneath the transmitter body. Use the turnkey to
unlatch the battery compartment. Remove the spent
batteries and insert eight D-cell (LR20) Alkaline or Ni-Cad
batteries.
NOTE: When installing batteries always observe the
correct battery polarity as indicated on the battery tray.
3.1.2 Rechargeable battery packs
An optional NiMH Rechargeable battery pack is available
for the RD7000+ locator. This pack is interchangeable
with other Radiodetection Precision Locators that use 2
D-cell ( LR20) batteries.
An optional Lithium Ion rechargeable battery pack is
also available for the RD7000+ Tx1, Tx3 and Tx10
transmitters.
The rechargeable battery packs provide an estimated 8hour working time, depending on use.
Rechargeable battery packs are available in kits that
include the rechargeable battery pack and an AC adapter
or 12V vehicle adaptor.
The battery packs must be removed from their parent
units before connecting to a power source for recharging.
For more information, refer to the instructions that came
with your charger.
CAUTION! Do not heat the rechargeable battery
pack above 60°C (140°F) as this will damage their

3.4 Shutting down
To switch the locator or the transmitter off, press and hold
the key for two seconds.
NOTE: The locator will automatically power off if no
keys are pressed after a ve minute duration.
3.5 Headphones
Radiodetection supplies an optional headphone set
for the RD7000+ locator. The headphones feature an
adjustable headband to ensure a tight t when used in
the eld. The accessory headphones also feature volume
adjustment for both left and right speakers.
Connect the 3.5mm headphone jack into the locator’s
headphone socket, which is located next to the
accessory panel on the front of the locator.
NOTE: Before wearing headphones, lower the locator’s
volume levels to help prevent damage to your hearing.
Passive frequency detection takes advantage of signals
that are already present on buried metallic conductors. The
RD7000+ range supports up to three types of passive
frequencies: Power, Radio and Cathodic Protection System
(CPS, RD7000DL+ only) signals. You can detect these
frequencies without the aid of a transmitter if they are
present on the utility you are surveying.
3.6.2 Active frequencies
Active frequencies are applied direct to a buried conductor
using the transmitter. The transmitter can apply a signal
using two methods: induction and direct connection.
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 easier onto nearby conductors.
Direct connection
In direct connection, you connect the transmitter directly
to the pipe or cable you wish to survey. The transmitter
will then apply a discreet signal to the line, which you can
locate 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.
Connecting the transmitter to a pipe or line requires the
use of a direct connection lead or clamp and a ground
stake to complete the circuit. For more information about
signal clamps and other direct connection accessories,
please refer to Section 7.
WARNING! Direct connection to live wires is
POTENTIALLY LETHAL. Direct connections should
be attempted by fully qualied personnel only
WARNING! The transmitter is capable of
outputting potentially lethal voltages. Take care when
handling the terminals, connection leads and ground
stake, notify other technicians working on the line of

3.8 SideStepauto
SideStepauto allows the transmitter to calculate the
optimum frequency based on ground impedance.
The transmitter uses this information to optimize the
active frequency. SideStepauto helps to improve locate
accuracy by determining the best signal. SideStepauto
can also help to prolong battery life.

Section 4 – Locating cables and pipes
This section introduces the principals and techniques of
locating buried cable and pipe utilities with the RD7000+
system. For more information on the theory of cable
and pipe location, please refer to “ABC & XYZ of locating
buried pipes and cables”, which is available from
www.radiodetection.com
4.1 Antenna modes
The RD7000+ system supports three antenna modes to
suit your particular application or the local environment.
These modes are:
Peak mode (all models)
•
Null mode (TL and PL models only).
•
Peak/Null mode (all models).
•
4.1.1 Peak mode
Peak mode provides the most sensitive and accurate
mode for location and depth measurement. It provides
a sharp peak response with a corresponding small
decrease in sensitivity. Peak mode is always enabled
unless an alternative mode is selected using the menu.
In peak mode the following indicators are displayed by
the LCD:
Depth.
•
Current.
•
Signal strength.
•
Compass.
•
To select a peak mode:
Press and release the key to switch the
1.
locator on.
Press the antenna key until the peak mode icon
2.
is displayed on the LCD.
4.1.2 Null mode
To select null mode:
Press and release the key to switch the
1.
locator on.
Press the antenna key until the null mode icon is
2.
displayed on the LCD.
Null mode gives a null response when it is directly over
the line. The sharp, null response is easier to use than
the peak response but is vulnerable to interference and
should not be used for locating, except in areas where
there is no interference present (See 4.1.3 Combined
Peak/Null mode). In null mode, the locator will indicate
line position but not its orientation.
4.1.3 Combined Peak/Null mode
Peak/Null mode give you the advantages associated with
these modes simultaneously.
Use the proportional arrows to place the locator above
the NULL point. If the peak response is not at a maximum
then this is evidence of a distorted eld. If the peak
response is at its maximum level where the NULL point is
located then there is no or very limited distortion present.
In Peak/Null mode the following indicators are displayed
by the LCD:
Proportional right and left arrows.
•
Signal strength.
•
Current
•
Depth
•
Compass
•
To select Peak/Null mode:
Press and release the key to switch the
1.
locator on.
Press the antenna key until the Peak/Null mode icon
2.
is displayed on the LCD.
Null mode is used to verify a locate signal in environments
with limited or no electromagnetic distortion.
In null mode the following indicators are displayed by
the LCD:
Signal strength.
•
Right and left arrows.
•
Compass.
•
12 RD7000+ Operation Manual
4.2 Compass
The LCD compass provides a visual indication of the
direction of the target cable, pipe or sonde. The compass
is available when locating active frequencies as well as
CATV and CPS passive frequencies. The compass is
unavailable when the locator is set to detect passive Power
and Radio signals.

Move the locator left and right while walking along the
path of the line to observe the null directly over the line and
a peak response to each side of the line. As you move
the locator over the line, the left and right arrows (and an
accompanying tone) will indicate if the target line is to the
left or right of the locator.
Figure 4.2: Pinpointing a target line
Periodically switch to peak mode, locate the target line,
and verify its exact position.

Figure 4.3: Pinpointing with Peak/Null
With the antenna perpendicular to the line, make
1.
traverses across the line. Dene the point of maximum
response.
4.4 Pinpoint
Pinpointing a target line in peak mode, denes the exact
position of a target line after it has been traced and its
position is approximately known. Start with medium
output power from the transmitter, medium frequency
on the transmitter and locator, and peak mode on the
locator.
Set the locator sensitivity to approximately 50%.
NOTE: it may be necessary to adjust the sensitivity level
throughout the pinpointing to keep the bar graph on
scale.
Without moving the locator, turn it round as if it is on a
2.
pivot. Stop at the point of maximum response.
Hold the locator vertical with the antenna just above
3.
the ground and move the locator from side to side
across the line. Stop at the point of maximum
response.
With the end of the antenna close to the ground,
4.
repeat steps 2 and 3.
Mark the position and direction of the line.
5.
Repeat the steps of the procedure to increase pinpoint
accuracy.
RD7000+ Operation Manual 13
Page 20
Switch to null response mode and move the locator to
nd the null position. If the position of the peak and the
null pinpoints correspond, it can be assumed that the
pinpoint is precise. The pinpoint is not precise if the marks
do not correspond, but both marks will show an error
to the same side. True line position will be close to peak
position.
The line lies half the distance to the other side of the peak
position as the distance between the peak and the null
positions.
Figure 4.4: Passive sweep
4.5 Sweep and search
There are a number of techniques available for locating
unknown lines in an area. Using these techniques is
particularly important before conducting any excavation
work to ensure that buried lines are not damaged.
4.5.1 Passive Sweep
A passive sweep will locate any Power, Radio or CPS
(RD7000DL+ only) signals that may radiating from buried
conductors.
To perform a passive sweep:
Press and release the key to switch the
1.
locator on.
Press the key to select the passive frequency
2.
you wish to locate. You can select from the following
passive frequencies:
Power.
a.
Radio.
b.
CPS. (RD7000DL+ only).
c.
Adjust the sensitivity to maximum; reduce the
3.
sensitivity to keep the bar graph on scale when there
is a response.
Traverse the area in a grid search (Figure 4.4), at a
4.
steady walk, and hold the locator comfortably with
the antenna in line with the direction of movement and
at right angles to any lines that may be crossed.
Stop when the locator response rises to indicate the
presence of a line. Pinpoint the line and mark its position.
Trace the line out of the area being searched. Resume
grid search in the area.
In some areas there may be a confusing amount of
50/60Hz power signals. Lift the locator 50mm from the
ground and continue the sweep.
Switch the locator to Radio Mode if the locator supports
this feature. Increase sensitivity to maximum and repeat
the above grid search procedure over the area. Pinpoint,
mark, and trace out any lines that are located.
In most, but not all areas, radio mode will locate lines that
do not radiate power signals and a grid search should be
made in both power and radio modes.
4.5.2 Inductive search
An inductive search procedure is the most certain
technique for locating unknown lines. This type of search
requires a transmitter and locator and two people. This
type of search is referred to as a ‘two person sweep’.
Before starting the sweep, dene the area of search and
the probable direction of lines crossing the area. Ensure
the transmitter is switched on in induction mode.
The rst person operates the transmitter and the second
person operates the locator. The transmitter induces a
signal onto lines as it passes over them and the lines are
then detected with the locator 20 paces upstream or
downstream of the transmitter. Hold the transmitter with
its length aligned with the assumed direction of any lines.
14 RD7000+ Operation Manual
Page 21
Figure 4.5: Inductive search
The second person holds the locator at the start of the
area to be searched and with the locator antennae at right
angles to the probable direction of the buried lines. Set
the locator sensitivity level as high as possible without the
locator picking up any airborne signals directly from the
transmitter.
When the transmitter and locator are in line both
operators start to move forward in parallel. The operator
with the locator sweeps it backwards and forwards,
keeping the locator vertical, as they proceed in parallel
with the transmitter. This method allows for misalignment
of the transmitter, locator and buried line.
The transmitter applies the strongest signal to the lines
directly below it, which are then located with the locator.
Move the transmitter from side to side to establish the
highest signal which indicates that the transmitter is also
directly above the line(s).
Mark the ground at the point of each peak signal detected
with the locator. Repeat the search along any other
possible paths of lines.
Once the positions of any lines have been marked,
reverse positions, place the transmitter over and along
each line in turn, and trace the line out of the search area.
RD7000+ Operation Manual 15
Page 22
Section 5 – Depth and current readings
5.1 Depth readings
The RD7000+ can measure the depth of buried
conductors down to depths of approximately 6 meters
(20 feet) for a line, or 15 meters (50 feet) when using
a sonde. RD7000+ will locate to greater depths but
accuracy may be reduced. The depth measurement is
to the center of the pipe or cable. The best readings are
detected from signals outputted by a transmitter rather
than from passive sources.
The RD7000+ is capable of determining depth when
locating passive power signals. However passive signals
on lines are less suited for measuring depth because
accuracy is questionable due to the passive signal being
present on more than one line.
NOTE: The accuracy of depth measurement is subject
to a number of factors and is meant as a guide only.
Exercise caution when performing any excavation.
WARNING! Do not make depth measurements
near bends or tees in the line. Go at least 5 meters
from a bend for best accuracy.
5.1.1 TruDepth and Compass
It is important to note that the RD7000+ will only display
depth when the locator is correctly oriented above the
target line, cable or sonde. To ensure the locator is
correctly oriented, use the LCD Compass:
When locating lines, make sure the Compass displays the
line in the 6 o’clock position.
When locating sondes (see Section 10.4), make sure the
Compass displays the line in the East / West position.
To avoid signal distortion, do not apply the signal by
induction. If direct connection or signal clamping is not
possible, place the transmitter at least 15 meters from the
point of any depth measurements.
Depth measurements are not accurate if there is audible
interference or if part of the transmitter signal has coupled
to a nearby line.
Conrming the peak position coincides with a null position
indicates that the position is suitable for making a depth
estimate.
Figure 5.2: Depth readings
Pinpoint the target line accurately with the locator.
•
Check the locator is directly over the line, the
•
antennae are at right angles to it and the locator is
vertical. Adjust sensitivity level to bring the bar graph
indication on scale.
Press the depth button to toggle between depth and
•
current readings.
If the ground appears to radiate a strong eld, perhaps
near a radio station, check depth by holding the bottom
of the antenna 50mm above the ground and subtract this
reading from the indicated depth.
Figure 5.1: Taking a depth reading
16 RD7000+ Operation Manual
Page 23
5.2 Verifying depth measurements
Method 1
Check a suspect or critical depth reading by lifting the
locator 50mm (2 inches) above the ground and repeating
the measurement. If the measured depth increases by
the same amount it is a good indication that the depth
reading is correct.
Depth measurements should be accurate to ±5% if
conditions are suitable. However, you may not always
know if the conditions are suitable so the following
techniques should be used to check critical readings:
Check that the route of the line is straight for at least 2
•
meters (6’6”) to either side of the measurement point.
Check that the signal response is reasonably constant
•
over the 15 meter distance to the transmitter and make
depth measurements to either side of the original point.
Check that there are no adjacent lines carrying a
•
signicant signal within 1 to 2 meters of the target
line. This is the most common source of error of depth
measurements as a strong signal coupled to
an adjacent line can often introduce ± 50% error.
Make several depth measurements at points slightly
•
displaced from the line’s apparent position. The
shallowest indication will be the most accurate and
will also indicate the line’s position most accurately.
Place the transmitter on top of a non-metallic object, such
as a cardboard box, on the ground and away from any
buried lines. Switch the transmitter on, ensuring that no
accessories are connected and that the transmitter is in
induction mode. To reduce the effects of ground coupling
the transmitter, when it is placed on the box, must be
more than 500mm above the ground
Hold the locator with the blade horizontal and pointing
towards the front of the transmitter and approximately ve
meters from the front of the transmitter.
Switch the locator on.
1.
Select the same induction frequency as is selected on
2.
the transmitter.
Select sonde mode on the locator.
3.
Move the locator from left to right and when the
4.
maximum signal is obtained place the locator on top
of a non-metallic object, such as a cardboard box,
on the ground. Ensure that the blade is horizontal
and pointing towards the transmitter. To reduce the
effects of ground coupling the locator must be more
than 500mm (18 inches) above the ground when it is
placed on the box.
Note the depth as indicated on the locator.
5.
5.2.1 Rough depth calibration check
This check is a quick and easy way of verifying that the
depth reading on the locator is within acceptable limits.
It can be used if you are getting inaccurate depth
readings from a cable or pipe for which you know the
approximate depth. Inaccurate depth readings could be
the result of the locator picking up a stronger signal such
as another cable or pipe running in close parallel to the
target pipe or cable.
There are two ways of checking the calibration of the
locator in the eld. Both methods require the use of a
transmitter:
Measure the distance from the base of the locator to
6.
the center of the transmitter using a tape measure.
Compare this reading with the depth reading on the
7.
locator.
The locator can be considered accurate if the difference
between the depth reading on the locator and the
distance measured with the tape is less than 10%.
Method 2
Apply a signal to a cable or pipe of known depth.
1.
Locate the cable or pipe; the locator will show depth
2.
automatically.
Compare the depth reading on the locator with the
3.
actual depth.
RD7000+ Operation Manual 17
Page 24
5.3 Current readings
5.3.1 Identification using current
measurements
Measuring current value on a line helps conrm the
identity of the line and provides information about the
condition of cable insulation or pipe coating.
5.3.2 About current measurements
The transmitter applies a signal or current onto a target
line. The current decreases in strength as the distance
from the transmitter increases. This rate of decrease
depends on the type of line and on soil conditions.
Regardless of the type of line and the frequency being
used the rate of decrease should be regular with no
sudden drops or changes. Any sudden or abrupt
current change indicates that the line or its condition has
changed.
In congested areas, where there is more than one line, the
locator may sometimes detect a stronger signal from an
adjacent line to which the signal has coupled or shares
common grounding because it is nearer the surface.
Although current measurement compensates for depth,
signal response will be less as the depth increases.
Figures 5.4 – 5.6: Taking current readings
The line with the highest current measurement, rather
than the line giving the strongest response, is the target
line to which the transmitter signal has been applied.
Measuring current provides useful information about the
position of bends and intersections. Measuring current
after a tee will indicate the main line that pulls more
current along its greater length.
Figure 5.3: Current readings
18 RD7000+ Operation Manual
Page 25
5.3.3 Applying a transmitter signal
mA mA mA
The transmitter signal can be connected, clamped or
induced to the target line in the same way as the signal
for line tracing is applied.
5.3.4 Signal current measurements
Pinpoint the line and conrm the accuracy of the peak
pinpoint with a null pinpoint. Check the locator is directly
over the line, with the antennae at right angles to it and
vertical.
The locator will automatically estimation and display the
depth reading on the LCD.
A signal coupled to a nearby line may distort the accuracy
of the measurement. If the accuracy of the reading is
suspect, sweep the area to check if other nearby lines
are radiating the signal. If other signals are causing
interference, it may be necessary to make the current
measurement at another point along the line.
Both antennae are needed to make a current
measurement and locator accessory antennae such as a
normal clamp or stethoscope cannot be used. Because
current measurement is a function of depth, it is only
available in the locating modes.

Section 6 – General Locating tips
6.1 Eliminating services
6.1.1 Induction
If several conductors are running parallel and it is not
possible to connect a transmitter, each line may be
located separately. Proceed as follows:
Perform a sweep of the area to nd the position and
1.
number of conductors in the area.
Map the direction in which the conductors are going.
2.
To trace the lines:
Select induction mode on the transmitter.
1.
Select the same frequency as on the locator.
2.
Place the transmitter on its side and in line with a
3.
conductor.
Ensure the conductor is directly below the transmitter.
4.
This will null the signal directly below the transmitter
5.
and, in addition, enable the other conductors to be
located.
Figures 6.1 – 6.4: Interference from services
Locate each conductor and mark its position.
6.
Move the transmitter down the route and continue
7.
locating and marking.
Trace each conductor out of the search area until the
8.
target line can be accurately located.
6.1.2 Unwanted signal coupling
Unwanted coupling of the signal from the target line to
another nearby line is one of the most common location
problems. It leads either to an error in the marked position
and depth of the target line or to marking the wrong
line. A certain degree of coupling is unavoidable in many
situations but there are ways in which a careful user can
reduce coupling and increase location reliability.
20 RD7000+ Operation Manual
Page 27
Avoid applying the signal by induction. The signal may
•
be coupling to more than one line directly from the
transmitter. Use the signal clamp where possible.
Identify points where lines may be bonded or in close
•
proximity to each other. Work toward these points
rather than away from them. For example, if gas and
water pipes are bonded within a building, apply the
signal at the valves or access points in the road rather
than in the building.
Reduce coupling to a parallel line by using a low
•
signal frequency where available.
Return signal owing on another line. Use a double-
•
ended connection to by-pass the ground return if
possible.
Choose a signal application point where the line is
•
furthest from other lines and not in a congested area.
When using single-ended connection, site the ground
•
stake as far from the target line as possible and away
from other buried lines.
Avoid using existing structures for ground
•
connections; other buried lines may be bonded to
them.
A bad ground connection or just laying the ground lead
on the surface at right angles to the line may result in
less coupling than a good ground provided long distance
tracing is not required.
6.2 Signal grounding
If the lighting column is made from concrete make the
transmitter connection to the cable sheath unless the
cable is earthed to the inspection doorframe. Connection
to the cable sheath applies the transmitter signal for a
considerable distance enabling the locator to trace cables
feeding illuminated street furniture as well as other street
lights.
WARNING! The live cable connector is for use
only by operators licensed or permitted to work on
live cables.
When the cable is not grounded at the column, open the
inspection door and connect the live cable connector to
the live or neutral conductor.
The use of a street light column as a means of applying a
signal to other power cables on the same electric circuit
is a possibility. The signal may be weak using this method
because it may have travelled some distance back to
the sub-station and out again on the other system.
With the locator used on a high sensitivity setting it is
often possible to locate a cable, which would otherwise
have been difcult or inconvenient to energize with the
transmitter signal.
6.2.3 Finding a good ground point
When using a direct connection, it is important to get the
best possible grounding for the transmitter. This provides
the lowest resistance ground path and the best output
signal. If it is not possible to use the ground stake the
following are examples of good alternative ground points:
Metal manhole covers.
•
6.2.1 Manhole covers
Sometimes when locating, it is not possible to insert the
ground stake into the earth, for example, when locating
on hard ground such as roads. In this case, the ground
return can be made by attaching the ground lead to the
metal frame of a manhole.
6.2.2 Using lighting columns
Direct connecting to a metal, street-lamp column is
almost as effective as connecting to the cable sheath
itself. Normally the cable sheath is bonded to the metal
column, therefore a simple connection onto the column
enables the user to locate the street lighting quickly and
safely without having to call out a technician from the
lighting company.
Metal drainage grates.
•
Metal railings.
•
Metal fence posts.
•
RD7000+ Operation Manual 21
Page 28
6.3 Double-ended connections
Large diameter water pipes and gas distribution pipes
that are laid in sections sometimes have insulated joints
between the sections and can be difcult to locate using
a single ended connect. This is because when using a
single ended connection ground return, signals can often
cause confusion by returning to the transmitter along
other lines. The problem sometimes occurs when return
signals appear stronger than on the target line, usually
because the target line is deeper than the line carrying the
return signal, or the return path may be a better electrical
conductor than the target line.
Applying a double-ended transmitter connection is a
useful technique for positively tracing and identifying
a target line in a situation such as a heavily congested
industrial site, provided there are access points at each
end of the line.
6.3.1 Making a double-ended connection
Connect the transmitter to an access point on the target
line. The transmitter ground is connected with a long
cable to another access point further along the line. A
complete circuit is achieved without using ground as
a current return path. The long cable should be kept
as far away as possible from the expected route of the
line. Radiodetection supplies 50 meter and 200 meter
extension cables for this purpose.
Figure 6.5: Making double-ended connections
This method of applying the transmitter signal is ideal for
positive identication of a target line. When a connection
has been made to two points on the same line, the same
level of current should be detectable all round the circuit.
The locator display should remain constant if the depth of
the line does not change.

Section 7 – Using Accessories
7.1 About accessories
Both the transmitter and locator are compatible with
a wide range of accessories, including the relevant
RD7000/RD8000/RD4000 accessories. Use clamps to
help apply a signal to pipeline or live wire. Use an AFrame to provide the RD7000+ locator with advanced
fault-nding capabilities.
When an accessory is connected, the locator or
transmitter will instantly recognize it and will enable
the mode appropriate to the accessory. For example,
attaching an A-Frame to the RD7000+ locator will
automatically switch the locator to fault-nd mode and
limit the number of available frequencies to those that are
compatible with the A-Frame. The LCD will also display
an icon of the accessory and will remove non-essential
icons from the screen.
For a full list of supported accessories, please refer to
Appendix 10.3.
7.2 Locator clamps
7.2.2 Connecting a clamp
Put the clamp connector into the accessory socket
1.
on the front of the RD7000+ locator.
Place the clamp around the pipe or cable and switch
2.
the locator on.
Set the frequency to the same as that on the
3.
transmitter.
Put the clamp around each cable in turn and note
4.
the bar graph response. Compare the strength
of response from each cable. The cable with a
substantially stronger response than the others will
be the cable to which the transmitter signal has
been applied.
Figure 7.1: Connecting a locator clamp
A locator clamp is used to positively locate and identify a
cable when several cables are running close together.
A target cable can be identied in a chamber, on a tray or
other access point by tting a clamp to the locator and
examining each cable in turn. Signal strength response
shown on the locator display should be noted for each
cable.
7.2.1 When to use clamps
Clamps can be used where:
Several cables or pipes run in close proximity to
•
each other.
A cable or pipe is accessible at an inspection hole
•
or manhole.
To ensure that the target cable has been correctly
identied, reverse the positions of the transmitter and
locator and check that the strongest response is still
received from the target cable by the locator in its new
position.
RD7000+ Operation Manual 23
Page 30
7.2.3 Available locator clamps
7.3.1 Connecting the clamp
Standard clamp
The clamp plugs into the locator accessory socket and is
used for cable identication at points where the cable can
be accessed. The standard clamp is suitable for cables
up to 100mm (4 inches) diameter.
Figure 7.2: Standard clamp
Plug the clamp into the transmitter output socket.
Put the clamp around the pipe or cable and ensure that
the jaws are closed. Switch the transmitter on.
The line should be grounded (earthed) on each side of the
clamp for the signal to transfer to the line. Ground the line
if necessary. An insulated cable may be traced even if it
has no actual ground connection, providing a reasonable
length is buried either side of the clamp to provide
capacitive coupling to ground (earth).
Figures 7.3 – 7.4: Connecting transmitter clamps
Small clamp
The small clamp performs the same function as the
standard clamp but is useful in cramped situations where
there is insufcient access for the standard clamp.
The small clamp is suitable for cables up to 50mm
diameter.
7.3 Transmitter clamps
The transmitter clamp ts around a pipe or cable and
safely applies a signal to a live cable without interrupting
or disconnecting the supply. The clamp applies a very
discriminating signal to a target line with reduced coupling
to other lines. A clamp can sometimes be a more effective
method of applying the signal than direct connection.
The target line will carry the strongest signal. The other
lines will carry the weaker return signal. If the system
comprises only two conductors, they may carry equal
signals.
WARNING! When clamping around a power cable
ensure that the clamp is connected to the transmitter
at all times.
NOTE: It is not necessary to make a ground connection
from the transmitter when using the clamp.
The clamp may buzz or vibrate if it is placed around a
power cable that has signicant net current ow. This is
normal and does not harm the equipment.

7.3.2 Available transmitter clamps
7.4.2 Choosing a suitable sonde
Although transmitter and locator clamps look the same,
they have different internal windings. To prevent the wrong
clamp being connected, transmitters and locator clamps
have plugs of a different orientation.
Standard signal clamp
The standard clamp applies the transmitter signal very
selectively and effectively to a target cable up to 100mm
(4”) diameter at frequencies from 8kHz to 200kHz.
The standard and small clamps have a double spring
action for positive toroidal contact.
Small signal clamp
The small signal clamp is useful for applying a signal to
a target cable in a pedestal or other place with limited
space. The clamp is suitable for cables up to 50mm (2”)
diameter and can also be used for frequencies from 8kHz
to 200kHz.
WARNING! The transmitter must only be
connected to live services using the appropriate
accessory such as a plug connector or live cable
connector.
Check that the sonde has sufcient range for the
application and is dimensionally small enough and
sufciently robust for the application. Ensure that the
frequency of the sonde corresponds with the locator
frequency; the locator will not locate the sonde unless
the frequencies are the same. Sondes are marked with
their transmitting frequency. Ensure that the means of
propelling the sonde is available together with the correct
ttings and couplings.
7.4.3 Preparation
Insert a new battery into the sonde. A new battery or a
freshly recharged battery should be used at the beginning
of each day and preferably at the start of each new job.
Before inserting the sonde, check that the sonde and
locator are at the same frequency and working correctly.
To do this, place the sonde on the ground at a distance
from the locator that is equal to the rated depth of the
sonde. Point the locator at the sonde with the antenna
in line with the sonde (the opposite of using the locator
to locate a line) and check that the bar graph reading
exceeds 50% at maximum sensitivity.
7.4.4 Propelling a sonde
7.4 Sondes
7.4.1 When to use a sonde
A sonde transmitter is a small battery powered signal
transmitter that can be inserted into non-metallic ducts,
drains or sewers so they can be located and traced with
a locator. A wide range of transmitting sondes is available
to suit different applications. Sondes can also be used
to pinpoint joints in iron gas pipes, locate blockages in
plastic water pipes and monitor the progress of horizontal
boring tools.
Sondes have a male thread at one end for connecting to
drain rods, or to other devices for inserting and propelling
the sonde along a drain or duct. Sondes may be oated
along drains at the end of a tether and oats are available
for tting to the sewer sonde and super sonde. Sondes
can be strapped to high-pressure water jets or similar
devices used for cleaning, maintaining and inspecting
drains. Sondes used in underground drilling and boring
operations are normally housed in the boring or drill head
behind the boring or drill bit.
RD7000+ Operation Manual 25
Page 32
7.4.5 Locating and tracing a sonde
Insert the sonde in the drain or duct access and locate
it while it is still just in view at the drain or duct entrance.
Hold the locator vertical directly over the sonde with
the antenna in line with the sonde. Adjust the locator
sensitivity so the bar graph reads between 60% and 80%.
The sonde radiates a peak eld from the center of its axis
with a ghost signal at each end of the peak. Move the
locator a little way behind and then in front of the axis of
the sonde to detect the ghost signals. Finding the two
ghost signals positively conrms the locate. Reduce the
locator sensitivity to lose the ghost signals but still indicate
a clear peak response directly over the sonde. Locator
sensitivity is now set for tracing the duct or drain unless
the distance between sonde and locator changes.
Figure 7.6: Sonde deployment
Propel the sonde three paces along the drain or duct and
stop. Place the locator over the supposed position of the
sonde. Do not adjust the sensitivity level.
To locate a sonde:
Move the locator backwards and forwards and stop
1.
when the bar graph indicates a peak. You can use the
LCD compass to orient the blade of the locator with
the direction of the sonde.
Rotate the locator as if the blade is a pivot. Stop
2.
when the bar graph indicates a peak.
Move the locator from side to side until the bar graph
3.
indicates a peak.
Repeat 1, 2 and 3 with the antenna vertical and
4.
resting on or just above the ground. The locator
should then be directly above the sonde with the
antenna inline with it. Mark the position of the sonde
and its direction.
Propel the sonde a further 1 or 2 meters, pinpoint,
5.
and mark the position. Repeat this pinpoint procedure
at similar intervals along the line of the drain or duct
until the survey is completed.
Figure 7.7: Locating a sonde
Figure 7.8: Calculating sonde depth
26 RD7000+ Operation Manual
Page 33
7.4.6 Checking sonde depth
Sewer sonde
The RD7000+ locator will automatically display the depth
of a located sonde providing the locator is correctly
oriented and positioned above the sonde. Using the LCD
compass as a guide, rotate the locator until the compass
indicates the sonde is in East/West position.
Calculation method
Pinpoint the sonde. Move the locator in front of the sonde
and still with the antenna in line with it, increase sensitivity
to nd the peak of the ghost signal. Move the locator
to behind the sonde ensuring that the locator blade is
always in line with the sonde. Find the null positions A
and B (see Figure 7.8). Measure the distance between
them and multiply by 0.7 to give an approximate depth
measurement.
7.4.7 Types and range of sondes
Standard sonde
The standard sonde combines compact size with
a strong signal and is the standard sonde for most
applications unless a smaller size, greater depth or
rugged construction sonde is required.
Figure 7.9: Standard sonde
This sonde incorporates a very strong housing and makes
the sonde suitable for use in municipal sewer systems.
The sonde has a long life for daily use in all conditions.
Figure 7.11: Sewer sonde
Super sonde
A particularly rugged sonde for use in deep sewers.
FlexiTrace
The FlexiTrace is a traceable plastic covered berglass rod
incorporating wire conductors and is used for locating small
diameter, non-metallic pipes to a depth of to 3 meters.
The FlexiTrace can be inserted into a pipe or duct as
small as 12mm/0.5 inch internal diameter with a minimum
bend radius of 250mm. Batteries are not required, as the
FlexiTrace is powered by the RD7000+ transmitter.
Super small sonde
This is a specialized sonde particularly suitable for no-dig
applications. This type of sonde has an interchangeable
battery compartment so that the length of the sonde can
be altered. Shortening the length of the sonde means that
fewer batteries can be accommodated and this will affect
battery life.
Figure 7.10: Super small sondes
The FlexiTrace can be used in two modes: Sonde mode or
Line mode. In sonde mode only the tip of the FlexiTrace is
energized whilst in line mode its whole length is energized.
To use as a sonde, connect both transmitter leads to the
FlexiTrace stud terminals. As the FlexiTrace terminals are not
color coded it does not matter to which terminals the leads
are connected. To use the FlexiTrace in line mode, connect
the red transmitter lead to a FlexiTrace terminal and ground
the black lead.

7.5 Stethoscopes
7.6 Submersible antenna
7.5.1 When to use a stethoscope
At times, it may not be possible to put a locator clamp
around a cable because of congestion or because of
inaccessibility. A stethoscope antenna should be used
in the place of the clamp to identify cables.
7.5.2 How to use a stethoscope
Plug the stethoscope into the locator accessory socket.
Press the concave head against each cable in turn to
detect a maximum signal.
7.5.3 Types of stethoscope
Large stethoscope antenna
The large stethoscope antenna, which plugs into the
locator accessory socket, is used for cable identication
in situations where the cable is exposed. It is particularly
useful for identifying heavy cables lying in a tray where
it is not possible to t a clamp. The concave detector
head on the end of the insulated, exible gooseneck is
placed rmly against the cable to be identied. If there
are a number of cables, the stethoscope antenna will
give the strongest response from the cable to which the
transmitter signal has been applied.
Small stethoscope antenna
7.6.1 When to use a submersible
antenna
Tracing buried pipes and cables across waterways and
estuaries are frequent and critical locating applications.
Less frequent but equally important is tracing and locating
lines between the mainland and offshore islands. When
locating pipes and cables the locator sensing antennae
should be as close as possible to the target line so it
is not practical to locate lines buried under a river or
seabed from the surface. In most cases, it is necessary to
measure the depth of cover to ensure the line is protected
from dragging anchors or other underwater hazards.
The submersible, double depth antenna is suitable for use
under water for tracing pipes or cables. There is a weight
at the bottom of the antenna for stability and the unit has
been pressure tested to IP68 to a depth of 100m.
The antenna is supplied with 10m of submersible marine
umbilical cable as standard, but lengths of up to 100m
can be supplied. The extra length enables the antenna to
be carried by a diver on a riverbed or seabed while the
locator is used in a surface vessel. It is crucial to have
effective communication between the operator with the
locator and the diver with the antenna.
Alternatively the antenna can be fastened to the end of
a non-metallic boom from a barge and lowered to the
riverbed or seabed.
The small stethoscope antenna has a 25mm concave
head at the end of a 2m lead. The small stethoscope
can be screwed into an extension rod or used at the end
of several extension rods joined together for identifying
inaccessible small cables.
Miniature hi-gain stethoscope
The miniature stethoscope is similar to the small
stethoscope but has no handle or facility for extension
rods.
The miniature stethoscope can also be used as a
miniature antenna for locations where the bulk of the
locator makes it inconvenient for use, such as locating
pipes or cables in walls.
7.6.2 How to use a submersible antenna
Apply the transmitter signal to the target line at an access
point on the shore. The submersible antenna line for
tracing the line underwater is plugged into the accessory
socket of the locator. The locator is used onboard a boat,
which should by positioned directly over the line. The
transmitting signal should be by direct connection with
the strongest possible signal and a low frequency (less
than 1kHz). Make a ground connection about 50m from
the transmitter. Test the quality of signal on the line before
locating on the water.
NOTE: The submersible antenna is calibrated to work
at a single frequency, which is specied at purchase.
28 RD7000+ Operation Manual
Page 35
Tips for using a submersible antenna
The user in the boat should be a specialist or have
considerable experience using a locator so that they can
give concise instructions to the diver.
It is prudent for the pair to practice working together on
dry land before attempting to locate underwater. Using
the antenna the diver should locate and trace a known
line blindfolded receiving directions from the user with the
locator out of sight of the line and the diver.
Because of rapid signal loss and a combination of large
surface area and very conductive soil there may be
problems applying a suitable signal for tracing a large
diameter pipe. It may be necessary to use a high power,
low frequency tracing signal.
It is necessary to dene a method of recording target line
position and depth before starting work in the boat or on
the seabed.

Section 8 – Fault-Finding
8.1 About fault-finding
The RD7000TL+ and RD7000PL+ models are capable of
locating cable to ground faults caused by damaged cable
sheaths. This process is known as “8K Fault-Finding”
as it uses an 8kHz signal applied to a target line with a
transmitter.
The accessory A-frame is used to locate cable sheath
faults on power and telecom cables. To use Fault-Find
you will need the following equipment:
RD7000TL+ or RD7000PL+ locator
•
Tx-3 or Tx-10 transmitter
•
Accessory A-frame connection leads.
•
8.2 Preparation
Using RD7000+ standard locating techniques locate the
cable for a short distance and trace and mark its route.
Remove all earth bonds from the line to be traced during
the fault-nding survey.
8.2.1 Connecting the transmitter
Switch the transmitter off.
1.
Push the connector plug into the transmitter
2.
accessory socket.
Clip the red connection lead to the cable or cable
3.
sheath ensuring that the area around the connection
is clean.
Extend the black connection lead as far away as
4.
possible and at 90° to the probable route of the target
cable and clip the connector to the ground stake.
Before taking the reference reading set up the transmitter
and locator as follows:
On the transmitter:
Switch the transmitter on by pressing the key.
1.
Select a fault-nding frequency using the key.
2.
Use the or arrows to increase or decrease the
3.
8kHz power output level.
If required you can use the BOOST setting if the fault
4.
is located on a high resistance cable or if the cable is
long.
WARNING! By selecting 8kHz output a high voltage
warning icon will appear on the transmitter’s LCD.
Move to the next step of the procedure.
On the locator:
Switch the locator on by pressing the key.
1.
Connect one end of the connection lead to the
2.
A-frame socket.
Connect the other end to the locator accessory
3.
socket.
The locator will automatically recognize the A-frame
4.
and display the A-frame icon on the LCD.
Select a fault-nding frequency using the key.
5.
NOTE: If the locator and transmitter are iLOC enabled
then you can remotely control the transmitter using the
locator. See Section 6 for more information.
Obtaining a reference reading:
NOTE: Always connect the black connection lead to a
ground stake and not a water pipe or buried cable, as
these may carry the signal.
8.2.2 Reference readings
It is good practice to obtain a reference reading from
the ground stake before you attempt to locate a fault
on a target line. Reference readings help to provide the
following information:
Severity of fault.
•
Survey interval.
•
30 RD7000+ Operation Manual
Position the locator approximately 2m (6 feet) from the
ground stake and push the A-frame spikes into the
ground with the green spike towards the ground stake
Attach the locator to the A-frame by the retention hook.
(If you are holding the locator separately, make sure that
the locator is in line with the A-frame and is pointing
towards the green spike.) The fault direction arrow should
be pointing away from the ground stake. If it is not, make
sure that the transmitter is connected correctly (red
connector to the cable and black to the ground stake)
Take the dB reading and keep it for reference. If there is a
single fault on the cable, it will be approximately the same
dB value as the reference reading.
Page 37
NOTE. To establish how often to take readings on the
cable, move away from the ground stake and take
further readings until the arrow has difculty in locking
and the dB reading is low. Measure the distance that
the locator is now away from the ground stake. This is
the distance that you can safely use between taking
readings on the cable to ensure that you do not miss
the fault.
8.3 How to find a fault
Starting from the transmitter, walk along the cable route
pushing the A-Frame spikes into the ground with the green
spike pointing away from the transmitter. Where there are
no faults the dB reading will be low and the direction arrow
may icker forward and back.
NOTE: Flickering arrows may also indicate that you may
be too far away from the fault or ground stake (or both)
for the locator to lock on.
If you are trying to locate
high resistance faults or
there is a long distance
between faults, carry on
with the survey and the
locator will lock on when
you get closer to the fault.
Figure 8.1: Cable sheath fault-finding
Take readings at the survey intervals determined by the
reference reading. To locate the cable during a Fault-Find
survey, press the key once and the locator will switch
to 8kHz null mode. Locate the cable using the normal
null mode technique. Press the key again to return to
Fault-Find mode.
As a fault is approached the Fault-Find direction arrow will
lock on to the fault signal and point forward and the dB
readings will increase. When the fault is passed the arrow
will point back towards the transmitter. Take readings at
smaller survey intervals to determine the exact point of
the fault.
When the A-frame is directly over the fault the dB reading
will drop as shown opposite.
NOTE: The values given are for illustration purposes
only and may not be the same as those obtained in
other situations.
To pinpoint the fault, turn the A-frame 90° to the cable
and Fault-Find until the exact point is found where the
arrow direction changes. The center line of the A-frame is
now directly over the fault.
Mark the ground to show the position of the fault. Find
the maximum dB reading in front of the fault by pushing
the A-frame into the ground at small intervals. Note the
dB reading. If the reading is approximately the same as
the reference reading, you can assume that there is only
one fault. If the reading is less than the reference reading,
keep surveying the cable for other faults.
Figure 8.2: Locating cable sheath faults with the locator and A-Frame
Replace the bonds between the sheath and ground at
each end of the line once the fault-nding survey has
been completed.
NOTE: If the cable runs under a road, use the
equipment as normal on the road surface as it can
sometimes detect signals when working on blacktop,
concrete, or paved surfaces. If necessary, try wetting
the road surface. Pouring a very small amount of
water around the bottom of the A-frame spikes before
each Fault-Find will generally ensure a good ground
connection.
NOTE: If the cable runs under a paved surface, the fault
can often be pinpointed by fault nding in the grass/soil
adjacent to the paving. Reduce the distance between
placing the A-frame spikes in the ground to allow for
the increased distance to the actual fault position.
