2.2. INSTRUMENT FUNCTIONS
The instrument is equipped with a TFT color LCD display, with capacitive "touch-screen"
that can be handled simply with the touch of a finger by the user and is structured with an
icon-based menu allowing the direct selection of measurement functions for quick and
intuitive use.
The instrument can perform the following tests (compatibly with the characteristics
described in Table 1):
RPE Continuity test of earth, protective and equipotential conductors with
test current higher than 200mA and open-circuit voltage between 4V
and 24V and continuity test as multimeter function
M Measurement of insulation resistance L/PE or L-N/PE with continuous
test voltage of 50V, 100V, 250V, 500V or 1000V DC
RCD Test on molded case RCD (Standard – STD) and on earth leakage
relay RCD ( ) General (G), Selective (S) and Delayed ( ) of type A
( ) and AC ( ) and B ( ) of the following parameters: tripping time,
tripping current, contact voltage
LOOP Measurement of line impedance/Loop P-N, P-P, P-E with calculation of
the assumed short-circuit current, also with high resolution (0.1m) (by
means of optional accessory IMP57), overall earth resistance without
causing the RCD tripping (NoTrip ), check of the interruption capacity
of magnetothermal protections (MCB) and fuses, I2t test, protection
check in case of indirect contacts
AUTO TEST Automatic sequence of NoTrip , RCD, M (L-PE, N-PE)
measurements in TT and TN systems
EARTH Measurement of earth impedance and ground resistivity by
voltammetric method and by an external clamp connected to the
instrument (optional accessory T2100)
SEQ Indication of phase sequence with 2- or 1-terminal method
AUX Measurement of environmental parameters (illuminance with white light
source and LED source, air temperature, humidity) by means of
optional external probes and DC voltage signals
LEAKAGE Measurement of leakage current (by means of the optional accessory
HT96U)
ΔV% Measurement of percentage voltage drop on main lines
PQA Real time measurement of main parameters (powers, harmonics, power
factor/cos) in Single phase and Three phase balanced systems
EVSE Automatic sequence of safety tests on mode 2 and 3 electric car
charging stations (by means of optional accessory EV-TEST100)
