1. GENERAL INSTRUCTIONS
Y
ou are the new owner of a 2000 count portable digital multimeter and
we thank you for your choice.
This instrument complies with the specifications set out in the NF EN
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) :
: The CAT I circuits are protected by measures limiting
CAT I
CAT II
transient overvoltages to appropriate low level.
Example
: The CAT II circuits are power supply circuits of
appliances or portable equipment with transient
overvoltages of an average level.
Example
: protected electronic circuits
: appliances and portable equipment
: The CAT III circuits are power supply circuits of power
CAT III
CAT IV
equipment with high transient overvoltages.
Example
:The CAT IV circuits may comprise very important
transient overvoltages.
Example
: fixed installation or industrial equipment
: primary supply level
∗ When using this multimeter, the user must observe all normal
rules concerning:
safety
- protection against the dangers of electric current.
- protection of the multimeter against misuse.
∗ For your own safety, only use the test probes supplied with the
instrument. Before use, check that they
14
Portable 2000 count digital multimeter
are in good condition.
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
1.1.4 Instructions
∗ Before opening up the instrument, always disconnect from all sources
∗ Any adjustment, maintenance or repair work carried out on the

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.

∗ If any faults or abnormalities are observed, take the instrument out
service and ensure that it cannot be used until it has been
of
checked out.
∗ It is recommended to remove the battery from the instrument if not
used.
1.2 Protection
This instrument is fitted with various protection mechanisms :
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
continuity and diode test measurements. This protection is reset
automatically after overload.

1.4 Warranty
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
or to a local agency, carriage to the centre shall be payable by the

1.5 Maintenance and metrological verification
Return your instrument to your distributor for any work to be done
within or outside the guarantee.
1.6 Unpacking - Repackaging
This equipment has been fully checked out mechanically and
electrically before shipping.
All precautions have been taken to ensure that the instrument arrives
at its destination undamaged.
However, it is advisable to carry out a rapid check for damage
sustained in shipping. If there is any evidence of damage, make this
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
) Before replacing the battery, 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 - Disconnect test leads from any inputs terminals.
2 - Using an appropriate tool, slide off the case bottom of the
instrument.
3 - Replace the battery.
4 - Replace the removable part.
