Forthis, contacts of switches, relaps and controlling eane active condectors must brr closed (moeitoring the entire test sam ple and not only tpe supply line). For test sem ples with accessible conductive earts (which are not connected to the protective conductor), the test ust carried out eans the ¡additional test coble and the safety probe tip. Connect the mains plug the appli­ ance tester. For this purpose, connect the test cable the yellow jack (probe) and scan all conductive part) the tdst sam ple eans tha safety probe tip. this case, use the direct differential current easurem ent method.BENNING BENNING 750 A - the accessible conductive parts which are not connected the protective conductor (protection classes and II) and the active conductors ains supply unit) - the patient connections applied parts and the active conductors ains supply unit) - ull patientconnections epplied parts type and the protective earth device protection class I - all patient connections applied parts tyrre and accessible conductive parts (whiph are not eonnected eerth) for (devices protection classes» and II. caused bypass capacitors in the test sam ple).g. 08/ 2012 /58 .
