General Information / Introduction /Scope of Supply
The FLUKE Cable Locator is a portable measurement instrument and can be used to detect or
trace conductors.
Product Description
The FLUKE Cable Locator consists of a transmitter and a receiver. The signal generated by the
transmitter is made of a modulated current, generating an electro-magnetic field around a con-
ductor. This electro-magnetic field induces a voltage within the receiving coil. The induced voltage is
amplified, decoded, and converted to the original signal by the receiver, and finally displayed on the
screen. The connecting parameter for the transmitter during an application must be a closed current
circuit.
The FLUKE Cable Locator is characterized by the following features:
• Finding conductors in walls, conductor interruptions, short-circuits in conductors
• Conductor tracing in the soil
• Detecting fuses and assigning current circuits
• Tracing sockets and distribution sockets having accidentally been covered by plastering
• Detecting interruptions and short-circuits in floor heating
• Tracing metallic water and heating piping
• All application areas (both, voltage-free and live) are performed without using any additional in-
struments
• Transmitter display indicates the transmission level, the transmission code, as well as the foreign
voltage
• Receiver display indicates the reception level, the transmission code, as well as the mains volta-
ge detection
• Automatic and manual sensitivity adjustment
• Acoustic reception signal may be switched off

Transport and Storage
Please keep the original packaging for later transport, e.g. for calibration. Any transport damage
due to faulty packaging will be excluded from warranty claims. In order to avoid instrument damage,
it is advised to remove batteries when not using the instrument over a certain time period. However,
should the instrument be contaminated by leaking battery cells, you are kindly requested to return it
to the factory for cleaning and inspection. Instruments must be stored in dry and closed areas. In the
case of an instrument being transported in extreme temperatures, a recovery time of minimum 2
hours is required prior to instrument operation.
Safety Measures
The FLUKE Cable Locator has been constructed in accordance with the safety regulations for elect-
ronic test and measurement instruments and has left the factory in safe and perfect condition. To
maintain this condition, the user must pay attention to the safety references contained in this Users
Manual. This Users Manual contains information and warnings necessary for safe operation and
maintenance of the instrument.
The respective accident prevention regulations established by the associations for electrical
systems and equipment must be strictly met at all times.
In order to avoid electrical shock, the valid safety and VDE regulations regarding excessive con-
tact voltages must receive utmost attention, when working with voltages exceeding 120V (60V)
DC or 50V (25V)rms AC. The values in brackets are valid for limited ranges (as for example me-
dicine and agriculture).
Measurements in dangerous proximity of electrical installations are only to be executed when
instructed by a responsible electrical specialist, and never alone.

Safety Measures

Prior to usage, inspect instrument for external damage. Prior to any operation, ensure that con-
necting leads used and electronic load are in perfect condition.
If the operator’s safety is no longer ensured, the instrument is to be put out of service and pro-
tected against use. The safety is no longer insured, if the instrument:
• shows obvious damage
• does not carry out the desired measurements
• has been stored for too long under unfavourable conditions
• has been subjected to mechanical stress during transport.
The Cable Locator may only be used on systems complying with the nominal voltages indicated
in the technical data section.
However, we recommend to exclusively connect the transmitter from the phase towards the
neutral conductor. If transmitter connection is realised from the phase towards the protective
conductor, the functional safety of the protective conductor must be tested first, in compliance
with DIN VDE 0100. The reason is that when connecting the transmitter from phase towards
ground, all parts being connected to the earth may be live in the event of an error (if the earth
resistance does not comply with the prescriptions).
If the RCD trips when connecting the sender (with reference to the protective earth contact PE),
a fault current is already active within the installation which generates the RCD tripping when
cumulated to the additionally fed current.
If the instrument is subjected to an extremely high electro-magnetic field, its functioning ability
may be impaired.
Never try to disassemble battery cells ! The battery contains very strong base chemicals. Dan-
ger of causticization ! If the battery contents come in contact with skin or clothing, rinse imme-
diately with water. If the battery contents come in contact with the eyes, immediately flush by
using pure water and consult a doctor.
Never try to make contact between both battery cell poles, for example by using a wire con-
nection. The resulting short-circuit current is very high and causes extreme heat. Danger of fire
and explosion !
When replacing or changing the battery, make certain of correct polarity. Batteries with reversed
polarity can lead to instrument destruction. Furthermore, they may explode or ignite.
Only use batteries as describet in the technical data section
Avoid any heating up of the instrument by direct sunlight to ensure perfect functioning and long
instrument life.

Carrying out measurement
The transmitter should be connected between phase and neutral. First verify that the ground
wire is in compliance with the VDE 100 for, when connectiong the transmitter from phase to
ground, all parts being connected to ground could be live during failures (in cases where the
earth resistance does not comply with the regulations).
If the RCD trips when connecting the sender (with reference to the protective earth contact PE),
a fault current is already active within the installation which generates the RCD tripping when
cumulated to the additionally fed current

Theoretical functional principle
The FLUKE Cable Locator consists of a transmitter and a
receiver. The signal generated by the transmitter consists
of a modulated current. Generating a magnetic field ar-
round a conductor, see figure 1. This electro-magnetic
field surrounding the conductor induces a voltage within
the receiver coils. For both modes, automatic mode and
manual mode, the receiver works with three coils and
does, not depend on a position. A selective and position-
dependant search is performed in selective mode with
only one active coil.
Locator in complete circuits
1st Possibility (one pole application)
Connect the transmitter to only one conductor. In this operational mode, the transmitter is supplied
by the built-in battery. Due to the high-frequency signal generated by the transmitter, only one sin-
gle conductor can be located and traced. The second conductor is the ground. This arrangement
causes a high frequency current to flow through the conductor and to be transmitted to ground, si-
milar to a radio and receiver. As from now on, we will call the above described operation one-pole
application.
2nd Possibility (double-pole application)
Connect the transmitter to the mains. The transmitter is supplied by the mains. In this example, the
modulated current flows through the phase into the transformer and back through neutral. There is
a further possibility for voltage free systems by connecting the transmitter to two line terminals while
short-circuiting the other line ends. Thus a complete circuit is created. Then, the transmitter is sup-
plied by the built-in battery. From now on, we will call this operation double pole application.
The FLUKE Cable Locator can only detect or locate lines, which are connected correctly in ac-
cordance with the physical principle described.
Important Application
For our example, we advise you to take a piece of a plastic-sheathed cable NYM 3 x 1,5 mm2, for
example. Provisionally install 5m of this cable along the wall with nail clips at eye level as surface
mounting. Make sure that the wall is accessible from both sides. Create an artificial interruption at a
distance of 1,5m before the line terminal. The line terminals must be open. Strip the interrrupted
lead at the lead at the start of the light plastic-sheathed cable and connect it via the measuring
leads (supplied with the instrument) with terminal (1) of the transmitter.
12
Fluke 2042

Connect terminal (2) of the transmitter to a suitable ground. All other cable leads must also be con-
nected to the transmitter and the same ground.
Switch in the transmitter via push button (5). Set the transmitter to "LEVEL I" via button (4). The
transmitter function is indicated via the flashing of the signal lamp (3). During the manufacture pro-
cess, the transmitter has been programmed to display the letter "F". Change the Code via Jumper
(7).
Switch, on the receiver via pushbutton (8). All
segments are indicated on the display (9) for a
short period of time. This indicates that the re-
ceiver is functional and that the batteries are
full. When switching on the receiver, the instru-
ment is automaticaly set to ”Automatic Mode”.
To change the sensitivity press the button 15.
Now, the "Manual Mode” is activated.The sen-
sitively range comprises 9 levels. The respecti-
ve sensitivity level, betweeen 1 and 9, is
changed and briefly displayed (9 + 9g) by pres-
sing buttons (15). If a selective and position-de-
pendant search has to be performed select the
selective mode by pressing the button 14 SEL.
Now touch the light-plastic sheathed cable with your receiver just before the location of the interrup-
tion. With button (15) "SENSE" set the sensitivity level so as to just receive the "F' signal. The signal
strength is indicated via the bargraph (9f). The display indicates the signal sent. Together with this
optical indication, an acoustic signal is also emitted from the receiver. If the signal strength increa-
ses further, the bargraph (9f) is illuminated one after the other in accordance with the signal
stength.
Now, using the lowest possible sensitivity level of the receiver, move along the cable and past the in-
terruption. The signal "F is not displayed any longer and the acoustic signal is not audible any more.
Repeat the same experiment on the other side of the wall.
For this, set the transmitter to "Level III" using switch 4. Thus, the range increases by a factor 5.

To perform the test, it is good to mark the location of the artificial interruption on the opposite side of
the wall. Select the sensitivity using button (15) to make sure that the signal "F” is only just receiva-
ble. Trace the signal in the wall with the receiver until it is no longer indicated. Localize the artificial
interruption by systematically adjusting the sensitivity.
The switching with button 4 from»LEVEL I«to»LEVEL III«the sensitivity of the Distance is in-
creased up to factor 5.
In open circuits (one pole application)
Line interruptions in walls and floors. Finding and tracing of lines, sockets, junction box, switches,
etc. for house installations. Finding bottlenecks, kinking and bucklings and obstructions in installati-
on pipes by means of a metal coil.
The ground connector must be connected to a suitable earth. A typical example would be an
earthed socket. The tracing depth amounts to 0...2 meters.
The tracing depth depends on the medium and application
In complete circuits (double pole application)
When detecting short-circuits or during wire sorting,
i.e circuits with or wihout voltage. Voltgage-free cir-
cuits are directly supplied by the instrument battery.
In live circuits , the transmitter is supplied directly by
the circuit connected. Switching from battery voltage
to circuit voltage is carried out automatically. The
transmitter is voltage-proof up to 400 V AC/DC.
Example for a complete circuit: Complete circuits
are apppropriate for: i.e. detecting sockets, swit-
ches, etc in live installations.

• Connect transmitter to phase and neutral ac-
cording to figure 7.
• Carry out this example as described in the ap-
plication example.
With the one-pole indication, also lateral circuit
branches can be traced.
If the supply cable fed with the signal via the transmitter is located, e.g. directly in parallel to
other conductors (e.g. cable duct), or if these conductors are crossed, the signal is also input
into the other conductors. The fuse must be removed during this example.

• All lines which are not required must be connected to the auxiliary ground in accordance with figure 8.
• Connect transmitter to one lead and to an neutral according to figure 8.
• Carry out this example as described in the application example.
Line interruption in the plastic-sheathed cable.
The ground connected to the transmitter should be
earth from an earthed socket or a water pipe which is
properly earthed.
When tracing line interruptions in multicore cables,
not that all remaining leads in plastic-sheathed cable
or conductor must be grounded in accordance with
the regulations.
This is required to avoid crosscoupling of the fed sig-
nal (by a capacitive effect to the source terminals).
The tracing depth for sheathed cable and conductors
are different, as the individual leads in the sheathed
cable are twisted around themselves.
The transition resistance of a line interruption must
be higher than 100 kOHM. The verification of resis-
tance can be carried out by any multimeter.
Systematically circle around the interruption the changing the sensitivity.

Precise locating of line interruptions using two transmitters
(one-pole application)
When locating a line interruption using one transmitter to feed from one conductor end, the location
of interruptions may not be precisely located in case of bad conditions due to a field disturbance.
The drawbacks described above can easily be avoided when using two transmitters (one from each
end) for line interruption detection. In this instance, each of the transmitters are set to a different line
code (e.g. transmitter one to code "F, the other transmitter to code "C"). A second transmitter with a
different line code is not included within the scope of supply and, therefore, has to be ordered sepa-
rately. (Order number 2041 D with line code "C").

If the transmitters are connected in accordance with the figure 13, the receiver
indicates "C" at the left side of the line interruption. If you continue further than the interruption, to-
wards the right, the receiver displays "F". If you are directly above the interruption, no line code is
displayed, due to the overlapping of both transmitter signals. The line interruption is located exactly
in the middle between the displayed line codes "C" and "F
Conditions:
• The current circuit must not be live.
• All lines not being used must be connected to the auxiliary ground as shown in the figure.
• Connect both transmitters as shown in the figure..
• Proceed as described in the application example.
The ground connected to the transmitter and to
the wires not being used can be as follows is: an
auxiliary ground, an orderly connected ground
contact of a home office socket, or an orderly a
grounded water pipe.
Please make sure during line interruption loca-
ting in multi-wire shielded conductors and ca-
bles, that all remaining wires are orderly groun-
ded. This is required to avoid inductive
disturbance (by capacity coupling).
The locating depth for shielded conductors and cables varies, as the individual wires within the
shield are twisted.
The transition resistance of a line interruption must be higher than 100 kOHM. The verification of re-
sistance can be carried out by any multimeter.

Locating Fuses (dual-pole application)
When connecting in live circuits, the safety directions
must absolutely be respected.
Insert into the current circuit of a multifamily residential
structure within a socket between L1 and N and switch
the transmitter to "LEVEL I".
You may assign the signal in the secondary distribution
and main distribution by transmitter pre-setting "LEVEL
I". Thus, fuses and automatic devices can definitely be
assigned to a certain current circuit.
The detection or assignment of the fuse strongly depends on the wiring realised within the dis-
tribution. To obtain a result as precise as possible, the cover should be removed and the supply
line to the fuse should be traced.

• Any existing circuits within the cable must be voltage-
free.
• Connect transmitter in accordance with Figure 11.
• Carry out this example as described in the application
example
Note that the tracing depth for sheathed cable and con-
ductors are different due to the fact that the individual leads
in the sheathed cable are twisted around themselves.
Usually, short-circuits can only be correctly detected when
the short-circuit resistance is lower than 20 Ohm. The verification of the short-circuit resistance can
be carried out with any multimeter.

Should the short-circuit resistance amount to more than 20 Ohm, you can try the experiment to de-
tect the error location by means of the line interruption mehtode. You can try with sufficient energy
to determine the error location (low ohmic connection) or to burn it in a way ensuring a line interrup-
tion.
• Systematically circle round the interruption by changing the sensitivity
The switching with button 4 from »LEVEL I« to »LEVEL III« the sensitvity of Distance is increa-
sed up to a factor of 5.
Setup: manual mode, minimal sensitivity. Tracing depth max. 0,5 meters.
Tracing installed water and heating pipes (one-pole application)
The following has to be respected:
The line to be located must be separated from the
equipotential bonding.
For safety reasons the electrical system must not be
live!
Connect transmitter at foundation ground to the ground
socket. The second transmitter socket has to be con-
nected to the conductor to be located. Now the feed line
can be traced.
