7.1.1 Cable Tester
All cables in use must be checked regularly with the built-in cable tester.
To do so, please proceed as follows:
1. Select the Start Mode and tap the button “Cable tester…”.
2. Make sure that nothing is connected to the BNC sockets and then confirm the
according message.
3. Then connect the blue banana cable to one of the two blue banana sockets.
4. Now touch with the free end of the blue connector cable the outer metal ring of the
BNC – socket, which is located directly below the blue banana sockets. Keep this
contact for a few seconds.
5. The cable tester now indicates whether there is a sufficient contact and therefore the
cable is intact or defect.
6. To exclude a loose connection, you should bend the cable near the connectors while
you observe the display. It should indicate a steady contact.
7. With the screen buttons “Channel II” and “Channel III” you can switch to the other
channels and test the other cables accordingly.
For testing the earthing cable, plug the banana plug of the earthing cable into a
banana socket and touch the BNC socket with the metal contact of the Schuko plug.
Attention: a functional suitable earthing is precondition for functional usage of
the Trikombin!
8. The black-red cable with a BNC plug can be tested by connecting it to a BNC socket
and touching the banana cable’s red and black ends.
