18.0 Testing Cables and Plugs

18.1 General

All cables and plugs can be examined for defects, such as parted
cables, by means of a continuity test.
This test is performed with the aid of a multimeter.
The way how the correct passage is being signaled (e.g. beeping
sound), depends on the kind of multimeter and the settings.

NOTE:
For information on the use of the multimeter, please see the
respective User’s Manual.

18.2 Testing Procedure

• Set the multimeter to continuity test.
• Loosen all plug connections of the cable to be tested.
• Connect one testing cable of the measuring instrument with a
contact at the input plug, and the other cable with the
corresponding-contact of the output plug.

NOTE:
Input plug and output plug can be determined freely.
However, during the measuring, they should not be
changed.
• Measure the continuity at the contacts on the cable’s input and
output plug.
• In the same way, check all connections for short circuit or
parted cables.
