The METRALINE PRO-TYPE EM I (Z525F) test adapter is used in the development and maintenance of e-charging points. The Gossen Metrawatt Z525F test adapter is suitable for VDE tests on e-charging points according to IEC 61851, both for initial commissioning and for repeat tests. It was designed for use with the Gossen Metrawatt device tester PROFITEST MTECH+ (IQ) or MXTRA (IQ). Various states of an electric vehicle can be simulated using a rotary switch on the test adapter. The charging station socket becomes live and can be tested with the PROFITEST MTECH+ (IQ) and MXTRA (IQ) test devices, for example. The measuring cables of the Profitest Master are connected via 4 mm safety sockets (L1, L2, L3, N, PE).
