1. PRECAUTIONS AND SAFETY MEASURES
This manual refers to two models: T2000 and T2100. Further in this manual, the word
“instrument” will be used to generically refer to both models unless otherwise specified.
The instrument has been designed in compliance with directive IEC/EN61010-1 relevant to
electronic measuring instruments. 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 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, even if no measurements are being
carried out.
 Avoid any contact with exposed metal parts, with unused measuring probes, circuits, etc.
 Do not carry out any measurement in case you find anomalies in the instrument such as
deformation, breaks, substance leaks, absence of display on the screen, etc.
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.
High voltage danger: electrical shock hazard.

1.1. PRELIMINARY
INSTRUCTIONS
 This instrument has been designed for use in environments of pollution degree 2.
 The instrument can be used for Resistance measurements (T2000 and T2100) and AC
current measurements (T2000) on installations with overvoltage category CAT III 150V
to earth. For a definition of measurement categories, see § 1.4.
 We recommend following the normal safety rules devised by the procedures for carrying
out operations on live systems and using the prescribed PPE to protect the user against
dangerous currents and the instrument against incorrect use.
 The instrument can be used on TT, TN and IT electrical systems of industrial, civil,
medical or zoo-technical type, both under ordinary conditions where contact voltage limit
is 50V, and under special conditions where contact voltage limit is 25V.
 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.
 Do not test circuits exceeding the specified current limits (T2000).
 Do not perform any test under environmental conditions exceeding the limits indicated in
this manual.
 Check that the batteries are correctly inserted.
