Quick and easy verification of electrical installations according to VDE 0413 (EN 61557) Parts 2, 3, 4, 6, and 7. The new model from the COMBI series is an innovative and versatile installation tester with essential functions for testing electrical systems and installations, as well as E-charging stations. Just plug it in and measure easily – the new auto-sequence measurement Ra – RCD – Riso makes it possible.

The insulation measurement against all three conductors (L-N-PE) and the large memory for 999 measurements with storage on three levels plus text comments are just a few of the many highlights of the new model range. A user-accessible help menu for all measurement functions provides valuable support when connecting the device to the system being tested, especially the automatic and menu-guided testing process for E-charging stations in the top model COMBI 521.
