**The Sonel MPI-540 multifunctional meter **is intended for testing** home and industrial electrical installations**. The instrument can be used to carry out measurements, the results of which determine the safety status of the installation. In addition, the user is able to record the parameters of the electrical networks located at these sites. This makes it possible to control the quality of electricity, and to measure electric shock protection parameters, **using a single universal device**.

Significant automation of measurements is made possible by the function of testing residual current circuit breakers in Auto mode, as well as measurement sequences pre-programmed by the manufacturer (so-called self-tests), which can also be extended with own sequences. Automatic measurement of insulation resistance of 3-, 4- and 5-core cables will be carried out with the Sonel AutoISO-1000C adapter.

**Sonel EVSE-01 adapter **allows to perform comprehensive **measurements of electric vehicle charging stations** – quickly and in accordance with applicable regulations. Simulating the charging cable (proximity pilot line – PP) and vehicle connection status (control pilot line – CP), it will bring the station into different operating states. This will enable **measurements in the field of electric shock protection**: Z_{S} fault loop impedance, R_{ISO} insulation resistance and checking the parameters of RCD residual current devices.

To facilitate diagnostics, one of the Sonel EVSE-01 sockets is provided with **pulse width modulation signal (PWM).**

**Application**

The Sonel EVSE-01 adapter enables measurements of AC electric vehicle charging stations with **type 2 connector.** Tests for 1-phase and 3-phase stations are available – both with and without ventilation.
