WARNING
Improper use
Danger to life or serious injury is possible due to contact with high electric voltage in case of
incorrect use of the test socket or 4 mm test sockets. The device might get damaged. The test
socket and the 4 mm test sockets carry mains voltage as soon as one or more LEDs for phase
indication light up.
• Use the test socket, 4 mm test sockets and BNC socket only for the testing purposes
described.
• Do not connect any other load to the test socket.
• The BNC socket is intended for connection to an oscilloscope.
