1. PRECAUTIONS AND SAFETY MEASURES

The instrument has been designed in compliance with directive IEC/EN61010-1 relevant to
electronic measuring instruments. For your safety and in order to prevent damaging the
instrument, please carefully follow the procedures described in this manual and read all
notes preceded by the symbol
Before and after carrying out the measurements, carefully observe the following
instructions:
• Do not carry out any voltage or current measurement in humid environments.
• Do not carry out any measurements in case gas, explosive materials or flammables are
present, or in dusty environments.
• Avoid contact with the circuit under test if no measurements are being carried out.
• Avoid contact with exposed metal parts, with unused measuring probes, circuits, etc.
• Do not carry out any measurement in case you find anomalies in the instrument such
as deformation, breaks, substance leaks, absence of display on the screen, etc.
• Pay special attention when measuring voltages higher than 20V, since a risk of
electrical shock exists
In this manual, and on the instrument, the following symbols are used:
Warning: observe the instructions given in this manual; an improper use could
damage the instrument or its components.
High voltage danger: electrical shock hazard.
Double-insulated meter
1.1.

PRELIMINARY INSTRUCTIONS

• This clamp has been designed for use in environments of pollution degree 2.
• It can be used for VOLTAGE measurements on installations with measurement
category CAT II 300V. For a definition of measurement categories, see § 1.4.
• We recommend following the normal safety rules devised by the procedures for
carrying out operations on live systems and using the prescribed PPE to protect the
user against dangerous currents and the instrument against incorrect use.
• Do not test circuits exceeding the specified current and voltage limits.
• Check that the battery is correctly inserted.
1.2.

DURING USE

Please carefully read the following recommendations and instructions:
Failure to comply with the Caution notes and/or Instructions may damage
the instrument and/or its components or be a source of danger for the
operator.
• When the instrument is connected to the circuit under test, do not touch any unused
terminal.
• Don't execute continuity test when external voltage is present.
1.3.

AFTER USE

• If the instrument is not to be used for a long time, remove the batteries.
with the utmost attention.
