You have just purchased a 20,000-count 4½-digit benchtop
multimeter. Thank you for your confidence in the quality of our
products.
This instrument conforms to safety standard NF EN 61010-1 (2001),
relating to electronic measuring instruments. For best quality
service, please read these instructions carefully and respect
operating precautions.
This instrument, single insulation, was designed for indoor use, in a
level 2 pollution environment, at an altitude below 2,000 m, It can be
used for CAT II installation circuit measurements, for voltage never
exceeding 600 V (AC or DC) in relation to earth.
CAT I: CAT I circuits are protected by devices limiting transient
overvoltage to a low level.
Example: protected electronic circuits
CAT II: CAT II circuits are power supply circuits for household or
analog units that can support medium-level transient
overvoltage.
Example: household appliance and portable tool power
supply
CAT III: CAT III circuits are power supply circuits that can support
major transient overvoltage.
Example: industrial unit or machine power supply
CAT IV: CAT IV circuits can support very high transient overvoltage.
Example: power input
•
Respect environment and storage requirements.
•
Make sure that power cable supplied with the unit is in good
operating condition (three-wire network: phase, neutral and
earth), conforms to safety standard NF EN 61010-1 (2001) and is
connected to instrument as well as network.
•
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 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.
