Electrical Installation  Meter with Power Analyzer MPI-540 Overview

The MPI-540 meter is designed for checking industrial and home electrical installations. The measurements taken by the device, determine the safety of the installation. In addition, the user has the possibility to register the parameters of electrical networks located at these facilities. This allows for the measurement of the parameters of protection against electric shock using a single universal device while verifying the quality of electricity. The Auto mode allows significant automation of measurements of the meter and makes it possible to test the functioning of residual current circuit breakers, as well as in pre-programmed measuring sequences, which can be extended with their own sequences. Automatic measurement of insulation resistance of 3-, 4- and 5-wire conductors are possible by using an additional AUTO ISO-1000C adapter.
