The Sonel MPI-536 was developed for the professional testing of electrical systems in residential and industrial environments. It provides reliable measurement results for assessing electrical safety and covers all requirements for modern installation tests. Particular emphasis is placed on extended functions for insulation diagnosis, including measurements up to 2,5 kV.
In addition to the classic test tasks such as loop impedance, RCD tests and earth measurement, the MPI-536 offers automated test sequences that enable complete systems to be tested efficiently, in compliance with standards and in a time-saving manner – even with RCDs or complex cable networks.
Insulation resistance in focus
The MPI-536 sets standards in the field of insulation testing:
-
Measurement of insulation resistance with up to 2500 V test voltage
-
Automatic RISO measurement on 3-, 4- or 5-core cables using the AutoISO-2500 adapter
-
Real-time visualisation of measured values via diagrams such as:
-
R(t)/U(t)
-
R(t)/I(t)
-
U(t)/I(t)
-
I(U)
-
-
Automatic calculation of the absorption and temperature coefficients
These functions enable detailed diagnosis of insulation quality – both during and after the measurement.

Measurement functions at a glance
The Sonel MPI-536 meets all requirements for standard-compliant testing of electrical systems:
-
Short-circuit and loop impedance measurement
-
RCD tests (trip time, trip current)
-
Insulation resistance up to 2500 V
-
Earth measurement (4-wire method including specific earth resistance)
-
Continuity testing of protective conductors and equipotential bonding
-
Lux measurement (with optional sensor)
-
Phase sequence testing
-
Motor rotation field testing
Efficient safety testing via automatic mode
For recurring test tasks, the MPI-536 offers:
-
Automatic test sequences for RCDs in auto mode
-
Configurable test sequences for standardised or individual test tasks
-
Fully automatic insulation testing of multi-core cables in conjunction with the AutoISO-2500
Optimised display and user guidance
The integrated 7-inch TFT touchscreen with 800x480 pixels enables clear and structured display of measurement parameters, diagrams and sequences. The display remains easy to read even in strong ambient light. Large symbols and an included stylus make operation easier – even with insulating gloves.
Help system for practical use
