Important instructions to read and to fully understand.
Useful information or tip to read.
The CE marking guarantees conformity with European directives and with regulations covering EMC.
The trash can 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.
Denition of Measurement Categories (CAT)
CAT IV Measurement category IV corresponds to measurements taken at the
source of low-voltage installations.
Example: power feeders, counters and protection devices.
CAT III Measurement category III corresponds to measurements on building
installations.
Example: distribution panel, circuit-breakers, machines or xed
industrial devices.
CAT II Measurement category II corresponds to measurements taken on
circuits directly connected to low-voltage installations.
Example: power supply to domestic electrical appliances and portable
tools.

PRECAUTIONS FOR USE
These current probes comply with safety standards EN 61010-1, EN 61010-031,
and EN 61010-2-032 for voltages of 300V in Category IV or 600V Category III.
The protection obtained by the instrument can be compromised if it is used in a
way that is not recommended by the manufacturer.
■ The operator and/or the responsible personnel must carefully read and clearly
understand the various precautions to be taken in use. Sound knowledge
and a keen awareness of electrical hazards are essential when using this
instrument.
■ Do not use the clamp on networks at higher voltages or in higher categories
than those mentioned.
■ Do not use the clamp if it appears to be damaged or incorrectly closed.
■ Before each use, check the condition of the insulation on the leads and
housing. Any item of which the insulation is deteriorated (even partially) must
be set aside for repair or scrapping.
