MPI-540 & MPI-535 are multifunction electric meter which helps in the safe installation of domestic and industrial appliances. In addition, the user has the possibility to register the parameters of electrical networks located at these facilities. This allows verification of the quality of electricity, and measurement of the parameters of protection against electric shock using a single universal device. Significant automation of measurements of the MPI-540 & MPI-535 meters makes it possible to test the functioning of residual current circuit breakers in the Auto mode, as well as in pre-programmed measuring sequences (so-called auto-tests), which can also be extended with own sequences.
With a multifunction electric meter, the automatic measurement of insulation resistance of 3-, 4- and 5-wire conductors is possible by using additional the AUTO ISO-1000C adapter.
