1. PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in compliance with directive IEC/EN61010-1 relevant to
electronic measuring instruments. Before and while carrying out measurements, observe the
following indications and read all notes preceded by the symbol
with the utmost attention.

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 being measured if no measurements are being carried out.

Avoid contact with exposed metal parts, with unused measuring probes, etc.

Do not carry out any measurement in case you find anomalies in the instrument such as
deformation, breaks, absence of display on the screen, etc.

Pay special attention when measuring voltages higher than 25V in special environments and
50V in normal environments, since a risk of electrical shock exists.
In this manual, and on the instrument, the following symbols are used:
CAUTION: observe the instructions given in this manual; an improper use
could damage the instrument or its components
High voltage danger: electrical shock hazard
Double insulation
DC voltage or current
Connection to earth
1.1. PRELIMINARY INSTRUCTIONS

This instrument has been designed for use in the environmental conditions specified in § 10.6.
Do not use in different environmental conditions.

The instrument may be used for measuring VOLTAGE and CURRENT in CAT III 300V with a
maximum voltage of 1000VDC between inputs. Do not use on systems exceeding the limit
values specified in § 10.1, § 10.2 and § 10.3

We recommend following the normal safety rules devised to protect the user against dangerous
currents and the instrument against incorrect use.

Only the accessories provided together with the instrument will guarantee safety standards.
They must be in good conditions and replaced with identical models, when necessary.

Check that the batteries are correctly inserted.

Before connecting the measuring cables to the circuit being measured, check that the desired
function has been selected.
