1 PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in compliance with standards IEC/EN61557-1 and
IEC/EN61010-1 regarding electronic measuring instruments.
For the operator's safety and to prevent damaging the instrument, follow the
procedures described in this manual and carefully read all notes preceded by
the symbol
Before and during measurements, carefully observe the following instructions:
• Do not perform any measurement in humid environments, in the presence of gas or
explosive or inflammable material or in dusty areas
• Even when no measurements are being performed, avoid any contact with the circuit
being tested, with exposed metal parts, with unused measuring leads or circuits, etc
• Do not perform any measurement when anomalies are found in the instrument, such as
deformations, breaks, substance leaks, no display view, etc
• Pay special attention when measuring voltages above 25V in special environments
(building yards, swimming pools, etc.) and 50V in ordinary environments, as there is
the danger of electric shocks.
In this manual and on the instrument, the following symbols are used:
CAUTION: it is necessary to consult the instruction manual to find the type of
potential danger and the actions to be taken.
Observe the instructions reported in the manual. An improper use could damage
the instrument and lead to dangerous situations for the operator.
DC voltage or current.
AC voltage or current.
Dangerous voltages: risk of electric shocks.
Instrument with double insulation.
1.1 PRELIMINARY INSTRUCTIONS
• This instrument has been designed for use in an environment with pollution level 2
• It may also be used to test industrial electrical systems up to overvoltage category IV
600V to earth with maximum voltage 600V between inputs
• Follow the usual safety rules to protect the operator from dangerous currents and
protect the instrument against improper use
• Never use the instrument resting on the floor, it must be placed over flat horizontal
surfaces
• Only the accessories supplied with the instrument guarantee safety standards. They
must be in good conditions and replaced, if necessary, with identical models
• Do not measure systems exceeding the current and voltage limit values specified
• Do not perform measurements in environmental conditions not within the limit values
indicated in this manual
• Before connecting the probes to the circuit to be tested, check that the correct function
is selected.
