The Sonel MPI-536 meter is designed for checking home and industrial electrical installations. The measurements that can be made, by using the device, provides the results which determine the safety of the installation. The instrument allows to make a set of measurements of the parameters of protection against electric shock using a single universal device.
In the field of insulation resistance control, Sonel MPI-536 has very wide possibilities - its maximum measurement voltage is as much as 2500 V. The insulation diagnostics is supported by the graphs R(t)/U(t), R(t)/I (t), U(t)/I(t), I(U), available both after and during the measurement. In addition, the instrument calculates the absorption coefficients and the temperature coefficients. Additionally, the Sonel MPI-536 enables automatic measurement of insulation resistance of 3-, 4- or 5-core cables or wires using the optional AutoISO-2500 adapter.
Significant automation of measurements of the meter makes possible to test 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.
MPI-536 can be used for all measurements for commissioning of electrical installations in accordance with applicable regulations:
Short circuit loop impedance (also in circuits secured with RCDs),
RCD parameters,
Insulation resistance,
Earth resistance (4 measurement methods + soil resistivity measurement),
Continuity of protective and equipotential bondings,
Light intensity measurement,
Phase sequence test,
Motor rotation direction test.
