The ideal tool for daily use - versatility pays off!

Profiscan APP The PROFITEST MXTRA test instrument provides professional electricians with a technically advanced, universal measuring tool for testing protective measures in electrical systems. As of immediately, users can operate the test instrument even more easily with the help of the ProfiScan android app, and exchange data between the app and the PROFITEST MXTRA.

The system structure can be set up and managed, as well as read in to the test instrument, via the ProfiScan app. Amongst other things, electrical circuits and residual current devices can be entered to the system structure. After testing has been completed, the measured values can be read out and transmitted to ETC software via e-mail. Furthermore, the keyboard mode greatly simplifies operation of the test instrument. Screenshots can also be created and customer files from ETC software can be managed with the app.

The PROFITEST MXTRA enables comprehensive and reliable testing of protective measures in electrical systems in accordance with VDE 0100, part 600, and other country-specific standards.
