Memory of 990 measurements (57500 individual results), data transfer to a PC over the USB or wireless interface.
-
Battery or rechargeable battery power supply.
-
Real time clock (RTC) - measurement time saved in memory.
Low-voltage measurement of protective connection equipotential and protective bonding:
- measurement of the protective conductor continuity with current 200 mA
in both directions (in accordance with the EN 61557-4 standard),
- low-current measurement of resistance with acoustic and light signalling,
- automatic calibration of test leads - capability of using test leads of any
length.
Specifications:
Measurement of short-circuit loop impedance:
- impedance measurement with 23 A current (40 A for phase-to-
phase voltage),
- resistor limiting the current: 10 Ω,
- range of measurement voltage: 95...440 V, frequency 45...65 Hz,
measurement of short-circuit loop impedance with the resolution of
0.01 Ω in systems protected with RCDs of I ≥ 30 mA without
tripping them, Δn
- automatic calculation of short-circuit current; differentiation
between line and phase-to-phase voltage,
- measurements with the use of a UNI-Schuko plug with a
measurement triggering button (also with swapped L and N
conductors) or leads of lengths 1.2, 5, 10, 20 m, with possible use
of three-phase socket adapters (AGT).
Examination of AC, A and B type residual current devices:
- measurement of general, short-time delay and selective RCDs of
rated residual current 10, 30, 100, 300, 500 and 1000 mA,
- a function of automatic measurement of the full set of RCD
parameters (after a single push of the "START" button, the meter
performs the entire defined cycle of measurements, including the
L-PE short-circuit loop impedance measurement with 15 mA
current),
- the shape of leakage current characteristics selected by the user:
sinusoidal (starting with the rising or falling edge), pulsating
unidirectional current (positive or negative), pulsating unidirectional
current with 6mA direct current offset (positive or negative),
direct current (positive or negative),
- measurement of the I operating current with rising current, A
- measurement of the t tripping time for 1/2I , I , 2I , 5I , A Δn Δn Δn
Δn
- measurement of the U touch voltage and the R protective
conductor resistance B E without tripping the RCD,
- detection of swapped L and N conductors in a socket; no influence
on the performance of measurements,
- capability of the I tripping current and the t actual tripping time
measurement A AI with just one RCD tripping,
- voltage measurements in the range of 95...270 V.
Insulation resistance measurement:
- test voltages: 50 V, 100 V, 250 V, 500 V, 1000 V and 2500 V,
- insulation resistance measurements up to 10 G ,
- acoustic signalling of 5-second time intervals to facilitate capturing
time characteristics,
- measurement of 2 absorption coefficients (DAR, PI or Ab1, Ab2),
adjustable elapsing T , T , T times from the range of 1...600 s,
1 2 3
- protection of the meter against the presence of voltage on the
object and the appearance of voltage during measurement,
- automatic discharge of capacitance of the measured object after
finishing the measurement,
- automatic measurement of all resistance combinations of 3, 4 and
5-core cords and power cables with the use of the additional
AutoISO-2500 adapter.
