Measurement of short-circuit loop impedance:

- impedance measurement with resolution 0,001 Ω and 23 A current

  (44 A phase-tophase)

- short-circuit resistor R =10 Ω ZW

- measurement range: 95...440 V, frequency 45...65 Hz,

- measurement of short circuit loop impedance with resolution

  0,01 Ω, in protected systems without tripping the RCD’s with

   I 30 mA Δn

- automatic calculation of short-circuit current, differentiating

  between phase-tophase 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.

Tests of residual current devices (RCD), types AC, A and B:

- measurement of general, short-time delay and selective RCD’s

  with rated residual current of 10, 30, 100, 300, 500 and 1000 mA,

- automatic measurement of all RCD parameters (when the START

  button is pressed, the meter performs the whole measurement

  cycle, including the L-PE short circuit loop impedance 

  measurement with 15 mA current),

- user selected waveform of forced leakage current: sinusoidal (start

  from increasing or decreasing edge), unidirectional pulsating

  (positive or negative), unidirectional pulsating with DC bias

  (positive and negative), direct (positive and negative),

- measurement of tripping current I using the ramp current, A

- measurement of tripping time t at ½I , 1I , 2I and 5I , A

- measurement of touch voltage U and protective conductor

  resistance R B E without the RCD tripping,

- detection that L and N conductors are switched in the socket; will

  not affect the measurement,

- measurement of tripping current I and actual tripping time t at

  single activation A AI of RCD,

- measurement for 95...270 V voltage.

Insulation resistance measurement:

- test voltages: 50 V, 100 V, 250 V, 500 V, 1000 V,

- insulation resistance measurements up to 10 G ,

- capability of in-socket measurement with the use of the UN

  Schuko adapter,

- acoustic signalling of 5-second time intervals to facilitate capturing

  time characteristics,

- 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 object after finishing the


- automatic measurement of all resistance combinations of 3, 4 and

  5-core cords with the use of the additional AutoISO-1000C 


- acoustic signalling of five-second periods to enable determining

  the time profile during the insulation resistance measurements

Measurements of earth resistance:

- measurement with 3- and 4-pole methods with 2 additional


- measurement with the 3-pole method with and additional clamp,

- measurement with 2-clamp method.

Key Features:

MPI-530 meter is a multi-functional instrument for electric shock protection measurements including the option of various methods for measuring earthing and earthing resistance.

  • Measurement and recording of voltage, frequency, AC, cosφ and power

      (active, reactive and apparent), voltage and current harmonics up to 40, 


  • Quick verification of correctness of the PE conductor connection with the use of a touch electrode.

  • Phase sequence checking.

  • Innovative memory with description of measurement points, facilities,

       names of customers (max. 10000 results of each measurement).

  • Power supply from rechargeable of disposable batteries (optional).

Low-voltage measurement of protective connection
and equipotential bonding resistance:

- continuity measurement of protective conductor with 200 mA current in

  both directions,

- low current measurement with sound signal,

- autocalibration of test leads – leads of any length can be used.
