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.
