PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in compliance with standards IEC/EN61557 and IEC/EN61010-1
regarding electronic measuring instruments.
CAUTION
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.

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.
