1. PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in compliance with Standards IEC/EN61557 and
IEC/EN 61010-1 relevant to electronic measuring instruments.
CAUTION
For your safety and in order to prevent damaging the instrument, please
carefully follow the procedures described in this manual and read all notes
preceded by the symbol
with the utmost attention.
Before and after carrying out the measurements, carefully observe the following
instructions:
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, unused measuring probes, circuits, etc.
Do not carry out any measurement in case you find anomalies in the instrument such
as deformation, substance leaks, absence of display on the screen, etc.
Pay special attention when measuring voltages higher than 25V in special
environments (such as construction sites, swimming pools, etc.) and 50V in normal
environments, since a risk of electrical shock exists.
Only use original accessories.
In this manual, and on the instrument, the following symbols are used:
CAUTION: observe the instructions given in this manual; improper use could
damage the instrument, its components and create dangerous situations for the
operator.
Presence of dangerous voltage (
30V): electrical shock hazard
Double-insulated meter
AC voltage or current
Connection to earth
1.1. PRELIMINARY
INSTRUCTIONS
This instrument has been designed for use in environments of pollution degree 2.
The instrument may be used for measuring and verifying the safety of electrical
systems of overvoltage category CAT III 300V (to earth) or CAT II 350V (to earth).
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. If necessary, replace them with identical models.
Do not test circuits exceeding the specified current and voltage limits. Do not perform
any test under environmental conditions exceeding the limits indicated in § 10.3.
Check that the batteries are correctly inserted.
Before connecting the test leads to the circuit to be tested, make sure that the switch is
correctly set.
