The device may only be switched on after connection to the measurement object! Operation on voltage-free lines WARNING Risk of fatal injury from electric shock... - Page 15 Setup/connection A direct connection to the measurement object must be made using the connection cables provided. Depending on the purpose of the measurement and the method used, the type of connection may vary. When locating/routing cables, a signal return current must be ensured through contact with the ground or, if necessary, through connection to an alternative conductor.
- Page 16 Setup/connection Particularly in cases where the lines are without ground isolation, the other end of the cable should be grounded or a loop test should be carried out where possible. Specific connection methods for locating sleeves and faults in twisted multi- core cables are provided in the operating instructions for the audio frequency receiver.
