- impedance measurement with resolution 0.001 and 23 A current

  (44 A phase-to-phase)

- short-circuit resistor R =10 ZW

- measurement of short circuit loop impedance with resolution 0.01 ,

  in protected systems without tripping the RCD’s with I ≥ 30 mA Δn

- automatic calculation of short-circuit current, differentiating

  between phase-to-phase and phase-to-neutral voltage,

- measurements using UNI-Schuko plug with measurement

  triggering button (also when L and N leads are exchangeable) or 

  1.2 m, 5 m, 10 m, 20 m test leads, with optional use of 3-phase

  socket adapters (AGT),

- selection of installation protections and automatic evaluation of

  measurements results

Examination of AC, A and B type residual current devices::

- MPI-530-IT allows measurements in IT network,

  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


- 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
