concerning safety
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.
Precautions and safety measures

requirements for electronic measuring apparatus. To get the best
(see. publication IEC 664-1) :
: The CAT I circuits are protected by safety measures limiting 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
: The CAT III circuits are power supply circuits of power equipment with
high transient overvoltages.
Example
: The CAT IV circuits may comprise very high transient overvoltages.

service
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.
16
5000-count portable digital multimeter, with current inputs
Chapter II
∗ When the multimeter is linked to measurement circuits, do not touch unused
terminals.
∗ W hen 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 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.
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

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.
