MPI-535 Multifunction Installation Tester The Sonel MPI-535 was developed to test residential and industrial electrical installations. The measurement results obtained by the tester provide information about the electrical safety of the installations. The MPI-535 can also perform a range of measurements whose results help ensure protection against electric shock. In addition, automatic test sequences allow all types of RCD protective devices to be tested using individual or predefined measurement sequences. This allows the entire installation to be tested quickly, efficiently, and in compliance with standards. Automatic test sequences for measuring insulation resistance in 3-, 4-, and 5-wire connections can be performed using the optional AutoISO-1000C adapter.
