1. SAFETY PRECAUTIONS AND PROCEDURES
This instrument complies with safety Standard IEC/EN61010-1 related to electronic
measuring instruments. For your own safety and to avoid damaging the instrument follow
the procedures described in this instruction manual and read carefully all notes preceded
by this symbol
.
When taking measurements:
 Avoid doing that in humid or wet places.
 Avoid doing that in rooms where explosive gas, combustible gas, steam or excessive
dust is present.
 Keep you insulated from the object under test.
 Do not touch exposed metal parts such as test lead ends, sockets, fixing objects,
circuits etc.
 Avoid doing that if you notice anomalous conditions such as breakages, deformations,
fractures, leakages of battery liquid, blind display etc.
 Do not apply a voltage exceeding 30V between any couple of inputs or between
each input and the ground reference to avoid risks of electrical shocks and/or damage
to the instrument
The following symbols are used in user manual and on the meter:
CAUTION - refer to the instruction manual - an improper use may damage the
instrument or its components
Danger high voltage: risk of electric shocks

1.1. PRELIMINARY
 This instrument has been designed for use in environments of pollution degree 2
 It can be used for DC VOLTAGE and DC CURRENT measurements up to 10V and
24mA respectively
 When using the instrument always respect the usual safety regulations aimed at
protecting you against the dangerous electric currents and protecting the instrument
against incorrect operations
 Only the leads supplied with the instrument guarantee compliance with the safety
standards in force. They must be in good conditions and, if necessary, replaced with
identical ones
 Do not test or connect to any circuit exceeding the specified overload protection
 Do not effect measurements under environmental conditions exceeding the limits
indicated in § 6.2.1
 Make sure that batteries are properly installed.
 Before connecting the test leads to the installation check the corrected mode function
to avoid any damage to the instrument
