2.2. GENERAL DESCRIPTION
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:
Continuity test of earth, protective and equipotential conductors with test current
higher than 200mA and open-circuit voltage between 4V and 24V
M Measurement of insulation resistance 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, check of
the interruption capacity of magnetothermal protections (MCB) and fuses, I2t test,
protection check in case of indirect contacts
SEQ Indication of phase sequence with 2- or 1-terminal method
ENV Measurement of environmental parameters (illuminance, 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
2.3. INSTRUMENT POWER SUPPLY
The instrument is supplied with six 1.5V AA IEC LR6 alkaline batteries, not included in the package.
The symbol "
" indicates the charge level. In case of low battery, stop testing and replace the batteries (see
§ 5.2). The instrument is capable of keeping data stored even without batteries. In order to maximize the
instrument's battery life, approximately 5 minutes after the last time a key was pressed, the instrument will
automatically switch off ("AUTOPOWER OFF")
