Beware of multiple services. C.Scope Locators will not always indicate services
that are close together or one above the other.
Do not use the equipment in areas where hazardous gases may be present.
Check for underground services before using the Earth Stake.
ALWAYS
EXCAVATE
WITH CARE
C.Scope Locators detect services radiating a detectable signal.
There may be some services that do not radiate and cannot be located.
Do not use the equipment outside of the temperature range -10˚C to +50˚C
as the batteries may cease to function adequately.
Geographical conditions such as hills and mountains may effectively screen signals
and prevent a detectable Radio signal.
C.Scope Locators alone will not always locate every service.
Use a Generator or Transmitter wherever possible.
The C.Scope Generator/ Transmitter leads UST NOT be connected directly to
a live service.
Performance may be impaired by unusually strong electromagnetic fields.
Do not hold the Locator earpiece close to the ear for extended periods.
WARNINGS
Always make sure that the Locator and Generator/ Transmitter are set to the same
frequency when used together.
Do not touch the metal of the C.Scope Generator/ Transmitter Crocodile Clips or
of the Plastic Pipe Tracer terminals when in use.

XT2 Transmitter Features

Locator Operating odes: Power ode
NOTE Generally these services should be detectable using the Radio or Generator/ Transmitter odes.
In Power ode the Locator detects power signals.
These power signals are present on all current carrying
electricity cables although not all are detectable. Power
signals may also flow along other conductors such as
metal gas and water pipes, telecom cables, metal fences
and railway tracks.
Limitations of Power Mode
Not all electricity cables can be found using the Power
ode. Here are the most important examples of
electricity cables that may not be detectable in the
Power ode:
Street lighting cables. When the lights are off, no
current flows and so no power signal is created.
Supplies to buildings or plant using very little or no
electricity may not have a detectable power signal.
Pot-ended or capped cables. These will never have any
current flowing through them but are possibly still live.
Disused or abandoned cables.
A few high voltage electricity cables. These can be
‘well balanced’, electrically and therefore radiate little
or no power signal.
Direct Current cables (such as those found on some
railway systems). These do not create their own
power signals.
Cables more than 3 metres deep.
WARNING Locators can only detect services radiating a detectable electromagnetic signal.
There may be some services that do not radiate these signals and cannot be located.
WARNING Absence of a power signal does not mean the service is not live.

11
Locator Operating odes: Radio ode
NOTE ost buried metallic services not found in Radio ode should be detectable by using Generator
ode with the Generator or Transmitter ode with the Transmitter.
WARNING Locators can only detect services radiating a detectable electromagnetic signal.
There may be some services that do not radiate these signals and cannot be located.
In Radio ode, the Locator detects signals from various
radio transmitters. These signals flow through the
ground and will tend to follow the line of least resistance
such as a buried metallic service. When this happens
the service can often be detected by using the Locator
in Radio ode.
Limitations of Radio Mode
Not all services will be detectable in Radio ode.
A strong radio signal present on one service may
be masking a weaker radio signal present on an
adjacent service.
It is not normally possible to determine what the
service is in Radio ode, only it’s position.
Radio signals do not favour one utility over another.
The depth of the buried service CANNOT be judged
by the strength of the radio signal alone.
Normally it is only possible to detect radio signals
present on services up to 2 metres deep.
A short service may not have enough signal to
be detected.

12
Locator Operating odes: All Scan ode
In All Scan ode, the Locator detects at ALL frequencies
in a wide band. Sometimes a signal that is outside of the
frequency range of the other search modes (Power, Radio,
and Generator/ Transmitter)will be present on a buried
metallic service. All Scan ode is a useful additional
search mode to employ as it may detect these ‘extra’
signals as well as the Power, Radio and Generator/
Transmitter signals.

13
Locator Operating odes: All Scan ode
Limitations of All Scan Mode
All Scan ode has exactly the same limitations as those
listed for the Power and Radio odes:
Street lighting cables when the lights are switched off,
supply cables to buildings or plant using little or no
electricity, pot-ended or capped cables, well balanced
high voltage cables and direct current cables may all be
missed on the All Scan ode.
A strong All Scan signal present on one service may mask
a weaker
All Scan signal present on an adjacent service.
It is not normally possible to determine what the service
is in
All Scan ode, only its position.

All Scan signals do not favour one utility over another.
The depth of the buried service CANNOT be judged by
the strength of the
All Scan signal alone.
Normally it is only possible to detect All Scan signals
present on services up to 2 metres deep.
A short service may not have enough signal to be detected.
WARNING Using the Power and Radio odes may be more effective in areas where there are many services
radiating an
All Scan signal.

Locator Operating odes: Generator/ Transmitter ode
In Generator/ Transmitter ode the Locator detects conductors
radiating a signal applied by the Generator/ Transmitter or detects
a signal radiated by a sonde.
The Generator/ Transmitter provides a means of applying a known
signal to buried metallic services which can then be detected using
the Locator. By detecting this signal it is possible to locate, trace
and identify the pipes or cables that may be carrying it.
There are a variety of methods by which the Generator/ Transmitter
signal can be applied to buried services:
Direct Connection using leads connected to the Generator/
Transmitter.
Induction without physically connecting to a service via the
Generator/ Transmitter radiated signal.
Signal Clamp connected to the Generator/ Transmitter.
Signal Injector connected to the Generator/ Transmitter.
Signal Hopping using the Direct Connection leads to couple onto
a service without physically connecting.
WARNING Locators can only detect services radiating a detectable electromagnetic signal.
There may be some services that do not radiate these signals and cannot be located.

C.Scope Locators can be powered by either eight standard alkaline
or by eight standard Nickel- etal Hydride rechargeable (Ni H) AA (LR6)size batteries.
Locator Battery Chec
Switch the Locator on by pulling up on the On/Off trigger positioned on the underside of the handle.
The Locator should emit a clear audible battery check tone for one second and the display should come on.
Check the battery level indicator in the bottom
left hand corner of the display. If there is only
one segment or no segments of the indicator
filled in then the batteries will need to be
renewed or recharged before locating work
can begin.
Changing Locator Batteries
Push the two clips back to release the battery compartment door. Remove ALL EIGHT used batteries and replace with
new ones. Be careful to insert the new batteries the correct way round in the holder. Replace the holder in the battery
compartment making sure that the two terminals on the holder make contact with the two terminals within the battery
compartment. Close the battery compartment door securely.
Using the Locator: Batteries Alkaline and Rechargeable
WARNING Do not change batteries in confined spaces where gas may be present.
WARNING Do not mix old and new or different types of batteries.
NOTE A spare battery pack can be carried inside the battery compartment.
NOTE Only use alkaline or Nickel- etal Hydride (Ni H) rechargeable AA (LR6)size batteries.
NOTE Dispose of the used batteries safely in accordance with local regulations.
NOTE The Locator will carry out an automatic Self Test when it is
switched on for the first time each day (see pages 16-17 for full details)

Using the Locator: Automatic Daily Self Test
The CXL2, DXL2 AND XL2 Locators have an in-built automatic Daily Self Test function.
This tests the Locator’s circuits and receiving aerials for correct performance.
The Self Test is automatically performed the first time the Locator is switched on each day
and takes approximately four seconds. The Locator will then be ready for use.
The Self Test process is indicated by ‘ ’ appearing on the display.
In the top left hand corner of the screen a countdown timer shows
the progress of the test.
16
NOTE When turning the Locator on for the first time it is important that no Signal Generators, Transmitters
or Sondes are operating within 5metres of the Locator.
NOTE Try not to switch the Locator on for the first time in an area with unusually high Power signals such
as next to an electricity transformer.

17
Using the Locator: Automatic Daily Self Test
After the Locator has successfully completed the
Self Test the Locator is ready for use as per normal.
If the Locator has failed the Self Test the Warning symbol
will appear in the bottom right hand corner of the screen.
If the error code: ‘ ’ is also displayed then this indicates
that there is either too much background interference
for the Self Test process to safely complete or there is
a Generator/Transmitter or Sonde transmitting nearby
which should be turned off.
In this situation, switch the Locator off and move to
a different area and the Locator will then automatically
repeat the Self Test when switched on. The Locator will
continue to repeat the Self Test process after every ‘fail’
and the Warning symbol will continue to stay on the
display until a successful test is carried out.
If the Locator continues to fail it’s Self Test then this
is indicating that there is a fault and the Locator should
be withdrawn from service. Contact C.Scope or a C.Scope
Authorised Service Centre for advice.

Your middle or little finger should be used to squeeze,
and hold on, the On/Off trigger.
Your index finger will then be free to adjust the
Sensitivity Control.
When in use the Locator should always be held upright.
NEVER swing the Locator such that it moves away from
the vertical. A single audible beep is sounded to indicate
if the Locator is being used incorrectly.

There are three stages to the locating process; searching,
pinpointing and tracing
1. Turn the ode Switch to the appropriate mode.
2. Hold in the On/Off trigger. The Locator should emit the audible
battery test tone and the digital display should come on. Check
the battery level indicator to confirm the batteries are usable.
3. Rotate the Sensitivity Control fully clockwise to its maximum
setting as indicated by the arrow on the control.
4. Carry out the search using a grid pattern as shown in the
diagram. Walk slowly and keep the Locator upright at all times
and stationary by your side.
5. As you approach the area in which there is a signal the
Locator will emit an audible response and show a visual
response on the display.
6. Keep walking until the audible and visual responses disappear.
Using the Locator: Searching
NOTE This search technique applies only to the
Power, Radio and All Scan modes. See ‘Using the
Generator/ Transmitter’ for the correct search pattern
when using Generator/ Transmitter ode.
NOTE Sometimes the Locator will give an audible
response and strong (full scale) visual response across
the whole of the search area. In this case turn the sensitivity
down slightly and repeat the search using the same grid pattern.
Search Grid Pattern

Having found a signal the next step is to pinpoint the source.
The closer the Locator is to the signal source the stronger
the response.
To Pinpoint a Signal
1. Keeping the Locator vertical, walk through the area of the
signal response. If the visual response goes up off the scale
then stop and reduce the sensitivity of the Locator slightly
before continuing.
2. The width of the signal response will shrink as the
sensitivity is reduced. Once it is reduced enough then a
clear peak response will be seen on the display as the
Locator traverses the service. The Locator is positioned
directly above the buried service when the display is at its
highest (peak)reading.
3. Carefully rotate the Locator over the peak reading until the
visual response falls to a minimum. The Locator will now be
roughly IN LINE with the direction of the buried service.
4. ark the position of the buried service.
Using the Locator: Pinpointing
NOTE The amount of sensitivity adjustment needed to pinpoint a service can vary depending on the mode being
used, the signal strength and the service depth.
