1. GENERAL INSTRUCTIONS
You are the new owner of a 5000 ct portable digital multimeter and we thank you for your
choice.
This instrument complies with the specification set out in the IEC 61010-1 + A1 + A2,
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. publication IEC 664-1) :
CAT I: The CAT I circuits are protected by safety 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 high 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 and,
check, before use, that they are in good working condition.
1.1.2. During use
∗Test equipment risk assessment : Users of this equipment and/or their employers
are reminded that Health and Safety Legislation requires them to carry out a valid
risk assessment of all electrical work so as to identify potential sources of electrical
danger and risk of electrical injury such as from inadvertent short circuits. Where the
assessment show that the risk is significant then the use of fused test leads
constructed in accordance with the HSE guidance note GS38 "Electrical Test
Equipment for use by Electricians" should be used.
∗Never exceed the protection limit values indicated in the specifications for each type of
measurement.

Chapter II
5000-count portable digital multimeter, with current inputs 17
∗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.
∗Fuses must be replaced with fuses of the same rating and type.
∗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.
∗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 1100 V at the VΩterminal,
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, capacitance, continuity and diode test
measurements. This protection is reset automatically after overload.
∗Two HBC fuses provide protection up to 600 V during measurements of intensity
type.
∗An IP protection rating of 40.
∗Maximum protection beteen mA and 10 A input terminals : 500 V.
1.3. Safety mechanisms
∗The battery unit cannot be accessed without first disconnecting the measuring leads.
∗When measuring voltages above 24 V, the sign blinks on the display.
∗When measuring voltages above 10 A, the sign blinks on the display and an
intermittent audible signal warns the user.
∗If the maximum range is repeatedly exceeded, an intermittent audible signal warns
the user in volt (DC and AC+DC) and current (DC and AC+DC) functions.

position of the selector switch, connect the red lead as follows:
Rotary selector switch position Input terminal
VLOW Z, VAC+DC, VDC,ADPDC (ADPAC+DC), Hz, , Ω, , V Ω
500 mADC (500 mAAC+DC) 500 mA
10 ADC (10 AAC+DC) 10 A
RS232 lead :

the DB9F plug to PC (COM port). Refer to § 5.
3.2. Switching on the instrument
The selector switch is on the OFF position.
Turn the selector switch to the required function.
All segments of the display come on for a few seconds. The instrument is then ready for
measurements.
3.3. Switching off the instrument
The instrument can be switched off manually by returning the selector switch to the OFF
position, or automatically after approximately half an hour if no key is pressed or the switch
is not operated.
)Note For user safety, automatic shutdown is disabled when a measured
magnitude (voltage/current) present at the input exceeds dangerous level
(
indicator displayed).
3.4. Special configuration
To adapt the configuration of the instrument to the measurement environment, the user
can choose 50 Hz or 60 Hz rejection :
Switch on with the rotary switch while holding down the MEM key. The selection is
reversed from the last configuration, is displayed for two seconds and remains backed
up in non-volatile memory.
To initialise the RS232 communication, keep the Pk +/- and keys simultaneously
pressed, then set the rotary switch to the selected position.
3.5. Multimeter maintenance
3.5.1. Fuse self-test
This check can be carried out with the multimeter in use without opening up the casing.
- 0.63 A fuse (F1) : set the rotary switch to the position and short-circuit the 500 mA and
VΩsockets. The display should read approx. 0.001 V. If the digital display indicates an
overflow « .OL ». The fuse is blown.
- 10 A fuse (F2) : set the rotary switch to the position and short-circuit the COM and VΩ
sockets. The display should read approx. 0.001 V. If the digital display indicates an
overflow « .OL ». The fuse is blown.

Chapter II
5000-count portable digital multimeter, with current inputs 21
3.5.2. Battery self-test

hours of operation, but specifications can no longer be guaranteed.
Replace the battery.
3.5.3. Replacing the battery or fuses
*Caution ! 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 input terminals.
2 - Using an appropriate tool, slide off the case bottom of the instrument.
3 - Replace the battery or fuse (respect the value and the type).
4 - Replace the removable part.
*Fitting the fuses :
Those fuses are correctly fitted ; those ones are not.
3.5.4. Cleaning
Clean the instrument using a damp cloth and soap. Never use abrasive or solvents.
3.5.5. Storage
To guarantee the measurement accuracy, after a long period storage in extreme
environment conditions, wait enough time for the instrument to acclimatise to the working
environment conditions (see environment specifications).
Fuses must be replaced
by fuses of the same
rating and type.
