The Sonel MPI-540 is a modern multifunction tester for the comprehensive analysis of electrical installations in residential and industrial areas. It enables all relevant safety and function measurements – with just one device. In addition, electrical grid parameters can be recorded and evaluated, including power quality and protective measures against electric shock.
Thanks to the auto mode for RCD tests as well as preconfigured and individually extendable autotests, test processes can be automated efficiently. With the optional adapter AUTO ISO-1000C, automatic insulation testing on 3-, 4- and 5-core cables becomes child’s play.
