1. INTRODUCTION
1.1 Inspection
Examine the shipping carton for any sign of damage. Inspect the unit and any
accessories for damage. If there is any damage then consult your distributor
immediately.
1.2 Description
If you are drilling a hole in a wall, a fl oor or are excavating a road etc. you will
need to know the layout of electricity cables, water or gas pipes etc. One method
would be to refer to constructional drawings, but if these are not available or are
not accurate, another means will be required to fi nd cables and pipes. Failure to do
so could result in serious injury or death if electric cables or gas pipes are drilled
through.
With the CD1000 cable locator electricity cables and pipes can easily be located.
The CD1000 is an easy to use, portable instrument, consisting of a transmitter, a
receiver and numerous accessories.
Using advanced digital circuit technology the transmitter sends to the target cable
(or metal pipe) an AC voltage modulated by digital signals, which generate an
alternating electric fi eld. The alternating electric fi eld is detected by the receiver
sensor head, magnifi ed and decoded. By localising the maximum signal strength
detected, the path of a cable or metal pipe can be traced, a fuse can be found, a
break in a conductor can be found, etc.
The transmitter can also be used as an AC/DC voltmeter and the receiver can be
used as a non-contact voltage indicator.
The CD1000 is a useful tool for those involved in the construction of
telecommunications cables, power cables, building pipes etc. as well as the
maintenance of such cables and pipes.
The CD1000 Transmitter has the following functions:
Easily changeable transmission code. This allows multiple units to be used on the
same site.
LED torch.
Mute function.
Battery low indication.
Self-Test function.
The CD1000 Receiver has the following functions:
LED torch.
Display backlight.
Mute function.
Battery low indication for receiver and transmitter.
Auto power off.
Manual or Auto sensitivity.
1.3 Accessories (included)
Bag.
TL47 test leads (with crocodile clips).
Earthing rod.
9V Alkaline battery.
1.5V Alkaline battery x6.
Instructions.
Accessories not included:
SB13 Safebreak Socket Test Adaptor (Order code MARSB13) – allows convenient
connection of the transmitter to wall sockets.
Extra transmitter units - allows faster identifi cation of multiple cables and more
accurate fault fi nding.
1.4 Battery Installation
Refer to Section 4.1 (Battery Replacement) for the battery installation instructions
for the CD1000 transmitter and receiver.
2. PRODUCT SPECIFIC SAFETY INFORMATION
Measurement Category III (CAT III) is applicable to test and measuring equipment
connected to the distribution part of the building’s low-voltage MAINS installation.
2.1 Precautions
This product has been designed with your safety in mind, but please pay attention to
the following warnings and cautions before use.
Warning
Before use check the unit for cracks or any other damage. Make sure the unit is free
from dust, grease and moisture. Also check any associated leads and accessories for
damage. Do not use if damaged.
Warning
Always test these units on an appropriate proving device or known voltage source
before using them to determine if a hazardous voltage exists in a circuit to be tested.
Warning
Many of the applications of the CD1000 require that the circuits being tested are dead.
Take all necessary safety precautions when proving a circuit is not hazardous live.
Warning
Do not use either unit if the battery cover is not fi tted.
Warning
When the transmitter is used in combination with test leads, the measurement
category of the combination is the lower measurement category of either this unit or
the test leads used. Likewise, if test lead accessories such as crocodile clips are also
used, the measurement category will be the lowest measurement category in that
combination.
Warning
When using test leads / crocodile clips, always keep your fi ngers behind the fi nger
guard on the test lead probe or crocodile clip.
Warning
Connecting the transmitter to live wiring beyond the specifi ed input voltage limits of the
unit may damage the unit and expose the operator to a shock hazard. Always check
the unit’s specifi ed limits before use.

Caution
Remove the batteries when not in use for an extended period, to avoid corrosion
from leaking batteries.
Caution
Avoid severe mechanical shock or vibration and extreme temperature.

3. OPERATION
3.1 General
There are two basic methods for using the CD1000:
One-pole application
The transmitter is connected to one conductor and a suitable earth. Due to the high
frequency signal generated by the transmitter a single conductor can be located
and traced. The high frequency signal on the conductor is transmitted to earth in a
similar way to a radio receiver.
The circuit being tested must not be live for these applications.
These applications are described in sections 3.19 a) to h).
Dual-pole application
Dead circuits:
Both transmitter leads are connected to the conductor to be tested to form a
closed circuit or loop so the signal returns back to the transmitter. Alternatively the
transmitter can be connected to two separate parallel conductors and the furthest
ends joined to form a loop.
The circuit being tested must not be live for these applications.
These applications are described in sections 3.20 c) to e).
Live mains:
The transmitter leads are connected to the phase and neutral conductors of a mains
circuit to be tested. Where there is no load on the circuit the closed circuit or loop
will be formed by coupling of the distributed capacitance of the cable being tested.
The circuit being tested may be live for these applications.
These applications are described in sections 3.20 a) & b).
3.2 Low Battery Indication
If the transmitter battery is low the
the buzzer will beep every 5 seconds. The
symbol will fl ash on the transmitter LCD and
symbol will also be displayed on the
receiver LCD when the receiver is receiving a signal from the transmitter.
If the receiver battery is low the
symbol will fl ash on the receiver LCD and the
buzzer will beep every 5 seconds.
Refer to section 4.1 (battery replacement) for battery replacement instructions for
the CD1000 transmitter and receiver.
3.3 Self-Test Function
The transmitter has a self-test function. A selftest failure will be displayed on the LCD.
