Congratulations on your purchase of the instrument and its accessories from METREL.
The instrument was designed on basis of rich experience, acquired through many years of
dealing with electric installation test equipment.
The multifunctional hand-held installation tester EurotestAT is intended for all tests and
measurements required for total inspection of electrical installations in buildings. In general
the following measurements and tests can be performed:
True rms voltage and frequency, phase sequence,
Insulation resistance,
Resistance to earth connection and equipotential bonding plus continuous
resistance measurement,
Line impedance / Voltage drop,
Loop impedance,
2
line/loop impedance
RCD protection,
Resistance to earth,
Tracing the installation,
Overvoltage protection devices,
Specific earth resistance measurement.
Tests can be performed on the following supply systems:
TN / TT,
IT,
110 V reduced low voltage (2 x 55 V), and
110 V reduced low voltage (3 x 63 V).
The high-resolution graphic display with backlight offers easy reading of results,
indications, measurement parameters and messages. Operation is simple and clear –
operator does not need any special training (except reading this instruction manual) to
operate the instrument.
In order for operator to be familiar enough with measurements in general and their typical
applications it is advisable to read Metrel handbook
Measurements on electric installations
in theory and practice
.
The instrument is equipped with all accessories necessary for comfortable testing. It is
kept in a soft carrying bag together with all accessories.
