7.12 Measuring sockets
Application
The measuring sockets are used to output analog signals. Any interconnectable signal can be
output on any measuring socket of the NCU.
• Max. output range of the test signal: 0 ... 5 V
• Measuring sockets have to be parameterized before use, as there is no default setting on
delivery.
Note
The measuring sockets should be used exclusively for servicing purposes.
The measurements may only be carried out by appropriately trained specialists.
