MPI-536 Multifunction Installation Tester The Sonel MPI-536 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-536 can also perform a range of measurements whose results help ensure protection against electric shock. The MPI-536 offers a wide range of capabilities for insulation resistance testing. The maximum measurement voltage is up to 2500 V. Insulation diagnosis is supported by the R(t)/U(t), R(t)/I(t), U(t)/I(t), and I(U) graphs, which are available both after and during the measurement. In addition, the device calculates the absorption coefficients PI, DAR, AB1, AB2, and the temperature coefficients k20 and k40. In addition, the Sonel MPI-536 enables automatic measurement of the insulation resistance of 3-, 4-, or 5-conductor wires or cables using the optional AutoISO-2500 adapter. Furthermore, automatic test procedures allow all types of RCD protective devices to be tested using custom or predefined measurement sequences. This enables the entire installation to be tested quickly, efficiently, and in compliance with standards.
