MPI-502

MPI-502 is equipment to perform the complete tests and verify on electrical installations according to the most common safety standards (IEC 61557, VDE 0100, BS7671).

Description

MPI-502 is a multifunction electrical meter that can be used for the following purpose.

Short circuit loop parameters measurements:

  • measurements of short circuit loop impedance in networks with rated voltage: 220/380 V, 230 V/400 V, 240/415 V, and frequency 45…65 Hz,
  • measurements of short circuit loop impedance with current 15 mA without tripping the circuit breaker.

Testing the RCD breakers of AC, A types:

  • testing of prompt, short-delay (general) and selective RCDs for the rated current values 10, 30, 100, 300, 500 mA,
  • IA measurement
  • RE and UB measurement without tripping the circuit breaker,
  • extended RCD test function AUTO, with measurement of ZL-PE with current 15 mA – measurement of IA and tA during one RCD tripping.

MPI-502 use for the detection of the replacement L and N in the socket and automatic conversion in the meter.

Low voltage resistance measurements of protective circuits and junctions:

  • measurement of resistance with ±200 mA current
  • calibration of test leads – possibility of using any length of test leads,
  • low current resistance measurement with acoustic signaling

Rapid check for the correct connection of PE wire using a touch electrode.

This Multifunction electrical meter also used for the measurement of mains voltage and frequency.

Power supply from LR6 batteries or NiMH accumulators (option).

MPI-502 meets the requirements of IEC 61557 standard.
