Overview of Multi-function Electrical Installations Meter | MPI-502

This Multi functional Electrical Installations Meter is performs complete test and verify electrical installations according to the most common safety standards (IEC 61557, VDE 0100, BS7671). Test includes various short circuit loop impedance test, multiple RCD breaker test, Low voltage resistance measurements of protective circuits, Voltage measurement, frequency measurement.

Features of Electrical installation meter.

• 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 Z_L-PE with current 15 mA - measurement of I_A and t_A during one RCD tripping.
• 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 accoustic signalling
• Rapid check for the correct connection of PE wire using touch electrode.
• Measurement of mains voltage and frequency.
• Power supply from LR6 batteries or NiMH accumulators (option).
• The device meets the requirements of IEC 61557 standard.
• measurement category: IV 300 V (III 600 V) according to EN 61010 - 1
• protection class acc. to EN 60529: IP67
