Testing of devices with mains voltage-dependent switching elements / mains supply units / relays such as controlled devices / tools, devices of information and communication technology as well as of devices which can be tested completely with mains voltage only. In mains operating mode, the protective conductor current/ contact current is measured by means of the required differential current / direct measurement method.
