1. PRECAUTIONS AND SAFETY MEASURES
1.1. GENERAL
This meter has been designed in compliance to IEC/EN61010-1 directive. For your own
safety and to avoid damaging the instrument we suggest you follow the procedures hereby
prescribed and to read carefully all the notes preceded by the symbol
.
Before and during measurements please take care of below points:
 Do not measure voltage or current in wet or dusty places.
 Do not measure in presence of gas, explosive materials or combustibles.
 Do not touch the circuit under test if no measurement is being taken.
 Do not touch exposed metal parts, unused terminals, circuits and so on.
 Do not use the meter if it seems to be malfunctioning (i.e. if you notice deformations,
breaks, leakage of substances, absence of messages on the display and so on).
The below symbols are used in this manual and on meter:
Caution: keep to what prescribed by the manual. An incorrect use could damage
the instrument or its components.
High voltage: risk of electric shock.
Double insulation.
Ground reference.
1.2. PRELIMINARY
INSTRUCTIONS
 This instrument has been designed for use in places with pollution class 2.
 It can be used for Voltage and Current measurements on installations of excess
voltage CAT IV 600V to earth and a 1000V maximum voltage between inputs
 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
 In case the lack of warning against the presence of voltage may constitute a danger for
the operator always carry out a continuity measurement before carrying out the
measurement of the live system to confirm the correct connection and condition of the
leads
 Only the accessories supplied with the instrument guarantee compliance with the
safety standards. Accordingly, they must be in good conditions and, if necessary, they
must be replaced with identical models.
 Do not take measurements on circuits exceeding the specified current and voltage
limits.
 Before connecting cables, crocodiles and clamps to the circuit under test, make sure
that the right function has been selected.
CAUTION
 Please perform a complete charging of internal battery for at least 5 hours
before using the meter the first time.
 Please press and hold the ON/OFF key for about 5s when turning on the
meter the first time.
