1. GENERAL INSTRUCTIONS

You 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) :

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

overvoltages 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 probes supplied with the

instrument. Before use, check that they are in good condition.

Portable 2000 count digital multimeter 15

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 2000 count digital multimeter

∗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 protection 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.

∗An IP protection rating of 40.

1.3 Safety mechanisms

∗The battery 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 VAC, VDC, mVDC, mVAC, IDC,

functions.

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

customer. The warranty does not cover the following :

1. Repairs necessitated by misuse of the equipment or use in

association with incompatible equipment.

2. Modification of the equipment or any related software without the

explicit authorization of the manufacturer.

3. Repairs necessitated by attempts to repair or maintain the product

made by a person not approved by the manufacturer.

4. Adaptation to a specific application not provided for in the

specifications of the equipment or the user manual.

5. Damage after a drop, a shock or flooding.

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.
