1.2 Terms of Warranty
Megger will accept a warranty claim brought forward by a customer for a
product sold by Megger under the terms stated below.
Megger guarantees that at the time of delivery Megger products are free
from faults in material and workmanship which would reduce their value
and serviceability to a large degree. This warranty does not cover any error
in the software supplied. During the warranty period Megger will repair
faulty parts or replace them with new parts or parts as new (with the same
usability and life as new parts) at their discretion.
Further warranty claims, in particular those from consequential damage,
cannot be accepted. Each component and product replaced in accordance
with this warranty becomes the property of Megger.
All warranty claims versus Megger expire after a period of 12 months from
the date of delivery. Each component supplied by Megger in the context of
warranty will also be covered by this warranty for the remaining period of
time, but at least for 90 days.
Each measure to remedy a warranty claim must be carried out exclusively
by Megger or one of their authorised service stations.
It is a precondition for accepting a warranty claim that the customer com-
plains about the fault, in a case of an immediately detectable fault within 10
days from the date of delivery.
This warranty does not cover any fault or damage caused by exposing a
product to conditions which are not in accordance with this specification, by
storing, transporting or using it improperly, or having it serviced or installed
by a workshop not authorised by Megger. No claim will be accepted in case
of wear and tear, will of God, or connection to foreign components.
For any damage resulting from a violation of their duty to repair or re-supply
items, Megger can be made liable only in case of severe negligence or
intention. Any liability for slight negligence is disclaimed.

1.3 Safety Instructions
Every person dealing with the assembly, operation, manitenance and repair
of this instrument is required to have read this manual with care.
At the time of supply, this device and its accessories are in line with the
state of the art in safety engineering. Due to the course of operations,
however, there may be places and parts on the device and its accessories
which cannot be protected optimally without interfering with its function and
operation by the user. For this reason it is a must that the operator has a
comprehensive personal experience in safety matters in order to protect
the staff and the devices.
GENERAL INFORMATION
Any operation on this device and its peripherals may only be carried out by
trained and / or instructed staff. Keep any other persons away.
This manual shall be available to the supervising, operating and
maintenance staff for reference. You are required to supervise all the time
that all safety regulations are observed when running or servicing the the
equipment.
Using the equipment improperly and for any other than its intended
purpose may result in hazards to life and limb, to the instrumentation and
the systems connected to it and may jeopardise the efficient operation of
the device (UVV, German Prevention of Accidents Regulation). You are
only allowed to use this device to the purpose stated by its manufacturer.
Operate the device and its peripherals only if they are in a good technical
condition. Never use any foreign parts on the device and its peripherals,
otherwise the required safety cannot be guaranteed. Abstain from any
mode of operation which might jeopardise the safety of the device.
In any case of trouble that might impair the safety of the staff, the operator
is required to shut the device down at once. The device may be switched
on again only after the damage has been remedied.
ELECTROTECHNICAL INSTRUCTIONS
Connect the device and its accessories according to instructions. Observe
all relevant DIN and VDE regulations.
Any repair and maintenance operations may be carried out only if the
instrument has been switched off (is in a dead state) and only by an
electrotechnical expert according to the Prevention of Acidents regulation
(UVV). According to UVV, a person is regarded an electrotechnical expert if
he or she, due to his or her vocational training, knowledge and experience
as well as knowledge of relevant regulations, is able to assess the job he or
she has been assigned to do and to recognise any possible hazard.

14 man_fle10_en_03-4.doc
In order to avoid any damages to persons or property caused by the opera-
tion of the ‘FERROLUX® FL 10’ or in combination with other devices, al-
ways observe the following safety precautions:
Check whether in the immediate vicinity of the site where the ‘FERROLUX®
FL 10’ will be used there are any unprotected devices / system components
under voltage which you or your instrument may accidentally get into con-
tact with. This applies in particular to components which are under high
voltage (DIN VDE 100) or the voltage of which is not known.
Safeguard these components by means of insulating covers. If it is impos-
sible to do so for technical reasons, de-energize them or have them de-
energized for the time of your activity on this site. Before doing so, consult
the responsible supervisor and ask him to give his permission. Make sure
that all measures have been taken properly, e.g. by taking check meas-
urements by means of a meter the proper functioning of which you have
tested beforehand.

2. TECHNICAL DESCRIPTION ‘FERROLUX® FL 10’
2.1 Application
Our Line and Fault Locating System ‘FERROLUX® FL 10’ is used for pre-
cisely locating metal lines such as cables and pipework laid out in the
ground and for determining their depth below the surface. Furthermore it
can be used for detecting the location of faults on cables or lines.
The main field of application of our ‘FERROLUX® FL 10’ is in the location
finding of routes and faults in the following fields: Public power supply, tele-
communication services, water supply systems and civil engineering for
drawing up building plans and for the preparation of digging operations.
For route locating, receiver ‘FERROLUX® FL 10’ offers you a choice of 4
frequency ranges to implement different locating methods.
Frequency ranges:
•Range for passive locating methods
•Ranges for active locating methods using specific transmitter fre-
quencies as emitted by transmitters ‘FERROLUX® FLG 10’,
‘FERROLUX® FLG 50’ or ‘FERROLUX® FLG 200’
Locating methods:
•Location finding by the standard-minimum technique
•Location finding by the standard-maximum technique
•Precision location finding by the super-maximum technique
•Indication of signal flow direction by ‘SignalSelect’
•Automatic depth and current measurement
•Location of lay fields
•Cable selection with mini aerial (optional extra)
•Locating finding of sheath faults with sensor (optional extra)
•Depth measurement (digital + 45° technique)
•Fault location finding by the inductive method (optional extra)
