1. GENERAL INSTRUCTIONS
You are the new owner of a 4000 ct portable digital multimeter and we
thank you for your choice.
This instrument complies with the specifications set out in the IEC
61010-1, publication concerning safety requirements for electronic
measuring apparatus.
To get the best service from this instrument, read carefully this user's
manual and respect the detailed safety precautions.
The contents of this manual must not be reproduced in any form
whatsoever without our consent.
1.1 Precautions and safety measures
1.1.1 Preliminary
∗This device can be used for measurements on category ΙΙΙ
installations, for voltages never exceeding 600 V (AC or DC)
relative to the earth.
∗Definition of overvoltage categories (see IEC 664-1 publication) :
CAT I: The CAT I circuits are protected by measures limiting
transient overvoltages to appropriate low level.
Example : protected electronic circuits
CAT II : The CAT II circuits are power supply circuits of
appliances or portable equipment with transient over-
voltages of an average level.
Example : appliances and portable equipment
CAT III : The CAT III circuits are power supply circuits of power
equipment with high transient overvoltages.
Example : fixed installation or industrial equipment
CAT IV :The CAT IV circuits may comprise very important
transient overvoltages.
Example : primary supply level
∗When using this multimeter, the user must observe all normal
safety rules concerning:
- protection against the dangers of electric current,
- protection of the multimeter against misuse.
∗For your own safety, only use the test supplied with the instrument.
Before use, check that they are in good condition.

Portable 4000 count digital multimeter

1.1.2 During use
∗Never exceed the protection limit values indicated in the
specifications for each type of measurement.
∗When the multimeter is linked to measurement circuits, do
not touch unused terminals.
∗When the range of the value to be measured is unknown, check
that the range initially set on the multimeter is the highest possible
or, wherever possible, choose the autoranging mode.
∗Before changing functions, disconnect the test leads from the
circuit under test.
∗In TV repair work, or when carrying out measurements on power
switching circuits, remember that high amplitude voltage pulses at
the test points can damage the multimeter. Use of a TV filter will
attenuate any such pulses.
∗Never perform resistance or continuty measurements on live
circuits.
1.1.3 Symbols
Warning: Risk of danger.
Refer to the operating manual to find out the nature of the potential
hazards and the action necessary to avoid such hazards.
Attention : Risk of electrical shock
Earth terminal
Equipment protected throughout by double insulation.
The rubbish bin with a line through it means that in the European
Union, the product must undergo selective disposal for the
recycling of electric and electronic material, in compliance with
Directive WEEE 2002/96/EC.
Conforms CE
Power supply : 9 V (6LF22) battery
1.1.4 Instructions
∗Before opening up the instrument, always disconnect from all
sources of electric current and make sure you are not charged
with static electricity, which may destroy internal components.
∗Any adjustment, maintenance or repair work carried out on the
multimeter while it is live should be carried out only by
appropriately qualified personnel, after having taken into account
the instructions in this present manual.
∗A "qualified person" is someone who is familiar with the
installation, construction and operation of the equipment and the
hazards involved. He is trained and authorized to energize and
de-energize circuits and equipment in accordance with
established practices.
∗When the instrument is opened up, remember that some internal
capacitors can retain a dangerous potential even after the
instrument is switched off.

Portable 4000 count digital multimeter 17
∗If any faults or abnormalities are observed, take the instrument out
of service and ensure that it cannot be used until it has been
checked out.
∗It is recommended to remove the battery from the instrument if not
used.
1.2 Protection mechanisms
This instrument is fitted with various mechanisms :
∗Varistor protection for limiting transients of over 600 V at the VΩ
terminal, particularly 6 kV pulse streams as defined by the French
standard IEEE 587.
∗A PTC (Positive Temperature Coefficient) resistor protects against
permanent overvoltages of up to 600 V during resistance,
continuity and diode test measurements. This protection is reset
automatically after overload.
∗Two HBC fuses provide protection up to 600 V during measure-
ments of intensity type.
∗An IP protection rating of 40.
1.3 Safety mechanisms
∗The battery and fuse unit cannot be accessed without first
disconnecting the measuring leads.
∗If the maximum range is repeatedly exceeded, an intermittent
audible signal warns the user in all functions, except in Ω,
and Hz functions.
1.4Warranty
This equipment is warranted against any defects of manufacture or
materials according to the general conditions of sale.
During the warranty period (1 year), defective parts will be replaced,
the manufacturer reserving the right to repair or replace the product. In
the event of the equipment being returned to the after sale department

known immediately to the shipper.
Should you need to return the multimeter, preferably use the
original packaging and indicate the reasons as clearly as
possible on an accompanying note.
1.7 Cleaning
Clean the instrument using a damp cloth and soap. Never use
abrasive or solvents.
1.8 Replacing the battery or fuses
First disconnect test leads from any circuit under test, turn the
meter off and remove test leads from the input terminals .
Use the following procedure :
1 - Using an appropriate tool, slide off the case bottom of the
