1 Test socket for connecting the device to be tested
2 Button for testing devices of protection class 1 (devices with protective conductor and touchable conductive parts
connected to the protective conductor)
3 Button for testing devices of protection class 2 (protective insulated devices without protective conductor and with
touchable conductive parts) and for testing devices of protection class 3 (safety low voltage)
4 Button for testing the protective conductor current (differential measurement) or the contact current (direct meas-
urement) under operating conditions (the test object is supplied with mains voltage)
5 Button for switching the test voltage (250 V DC or 500 V DC) for measuring the insulation resistance
6 Button for testing 30 mA residual current circuit breakers (RCCB/RCD)
7 Button for testing three-phase devices under operating conditions (using optional measurement adapter)
8 Display, shows test progress and the individual results
