2.2. INSTRUMENT FUNCTIONS
The instrument can perform the following tests:
RPE 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.
LOOP Measurement of line/fault loop impedance P-N, P-P, P-E with
calculation of the prospective short-circuit current, overall earth
resistance without causing the RCD’s tripping (RA ), check of the
breaking capacity of magnetothermal protections (MCB) and fuses,
protection check in case of indirect contacts with 2-wire and 3-wire
connection
LoZ Measurement of line impedance/Loop P-N, P-P, P-E with calculation of
the prospective short-circuit current with high resolution (0.1m) (by
means of optional accessory IMP57)
ΔV% Measurement of percentage voltage drop on mains.
Lo Continuity test of earth, protective and equipotential conductors with
test current higher than 10A (by means of relative optional accessory)
RCD Test on molded-case standard, General and Selective RCDs of type A
( ) and AC ( ) and B ( ) of the following parameters: tripping time,
tripping current, contact voltage.
AUTO Automatic sequence measurements of RA , RCD, M functions with 3-
wire connection.
1,2,3 Indication of phase sequence with 1-terminal method.
DMM Multimeter function for Phase-Neutral, Phase-Phase, Phase-PE voltage
and frequency measurements.
