Multifunction electrical installation parameter meter MPI-520Start (WMPLMPI520S)

A digital multifunction meter for both installers and advanced meters. It allows you to perform all measurements in the electrical installation specified in the PN-EN 61557 standard: complex fault loop impedance, RCD switch parameters, insulation resistance, ground resistance, continuity of protective and equipotential connections.

The MPI-520S set includes basic measurement accessories. The use of modern solutions means that we have additional functions and features that simplify measurement, which are not available in other meters. The IP54-rated housing is resistant to mechanical damage, and the cover can be adjusted to many possible positions, allowing easy transport and use of the device in various positions.

• Measurements of complex short-circuit loop impedance: measurement voltage range: 95...440 V, frequency 45...65 Hz, measurement of complex short-circuit loop impedance with resolution up to 0.01 Ω.
• Testing residual current circuit breakers of type AC, A, and B: measurement of ordinary, short-term, and selective circuit breakers with nominal residual currents of 10, 30, 100, 300, 500, and 1000 mA.
• Insulation resistance measurements: measurement voltages: 50 V, 100 V, 250 V, 500 V, and 1000 V, insulation resistance measurement up to 3 GΩ.
• Low voltage measurement of protective and equipotential bonding resistance: measurement of the continuity of the protective conductor with current ≥200 mA in two directions.
