1. PRECAUTIONS AND SAFETY MEASURES
The models of the Gx Series have been designed in compliance with Directives
IEC/EN61557 and IEC/EN61010, relevant to electronic measuring instruments. 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 any 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 deformations, breaks, 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 higher than 50V in
normal environments, since a risk of electrical shock exists.
Only use original accessories.
The following symbols are used in this manual:
CAUTION: observe the instructions given in this manual; improper use could
damage the instrument, its components or create dangerous situations for the
operator.
High voltage danger: electrical shock hazard.
Double insulation
AC voltage or current
DC voltage or current
Connection to earth
The symbol indicates that the instrument must not be connected to systems with
phase-to-phase rated delta voltage higher than 415V.
1.1. PRELIMINARY
INSTRUCTIONS
This instrument has been designed for use in the environmental conditions specified in
§ 11.4.1. Do not use in different environmental conditions.
The instrument may be used for measuring and verifying the safety of electrical
systems. Do not use on systems exceeding the limit values specified in § 11
We recommend following the normal safety rules devised to protect the user against
dangerous currents and the instrument against incorrect use.
Only the accessories supplied with the instrument guarantee compliance with safety
standards. They must be in good conditions and be replaced with identical models,
when necessary.
Make sure the batteries are correctly installed.
Before connecting the test leads to the circuit being measured, check that the desired
function has been selected
