1. GENERAL INSTRUCTIONS
You have just acquired a portable digital multimeter and we thank you for your confidence.
This instrument complies with the specification of IEC 61010-1 + A1 + A2, 1995, con-
cerning 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 (cf. publication IEC 664-1) :
CAT I: The circuits of CAT I are protected by measures limiting transient
overvoltages to appropriate low level.
Example : protected electronic circuits
CAT II : The circuits of CAT II are power supply circuits of appliances or portable
equipment with transient overvoltages of an average level.
Example : appliances and portable equipment
CAT III : The circuits of CAT III are power supply circuits of power equipment with
important transient overvoltages.
Example : fixed installation or industrial equipment
CAT IV :The circuits of CAT IV 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 measuring probes which have been delivered with
the instrument : they conform to the IEC 61010-1 + A1 + A2, 1995 safety standard.
Before use, check 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 require 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 input
16
∗When the multimeter is linked to measurement circuits, do not touch unused
terminals.
∗When the scale of the value to be measured is unknown, check that the scale 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
Symbols used in this manual and on the instrument :
CAUTION : Refer to the instruction manual.
Incorrect use may result in damage to the device or its components.
DANGER : High voltage, risk of electric shock.
Earth
1.1.4. Instructions
∗Before opening the instrument, always disconnect from all sources of electric
current and make sure not to be loaded 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 one who is familiar with the installation, construction and
operation of the equipment and the hazards involved. He is trained and
authorized to energize, de-energize circuits and equipment in accordance with
established practices.
∗When the instrument is open, remember that some internal capacitors can retain
a dangerous potential even after the instrument is powered down.
∗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 devices
This instrument is fitted with various protection devices :
∗Varistor protection for limiting transients of over 1100 V at the VΩterminal,
particularly 6 kV pulse streams as defined in 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.

Chapter II
5000-count portable digital multimeter, with current input 17
∗Two HBC fuses provide protection up to 600 V during measurements of intensity
type.
∗An IP protection rating of 40.

FNote For user safety, automatic shutdown is also 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.

measurement are stored (capture time ≤500 ms). The signs MIN MAX AVG appear on
the display.
You can look up each of these values by repeatedly pressing the same key (short press).
The symbols MIN, MAX or AVG flicker with the selected value.
The three MIN, MAX, AVG values are stored in memory and can be read after quitting the
surveillance mode.
When you access the surveillance mode again, all previous values stored are cleared.
This key also desactivates the auto power-off, if it is pressed when switching on
(« P_OFF »).
