Use, Maintenance, and Care of the Devices
Visual Inspection
Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a
connection is made. Metal particles from the connector threads may fall into
the connector when it is disconnected.
In some cases, magnification is necessary to see damage to a connector; a
magnifying device with a magnification of
≥
10
×
is recommended. However, not
all defects that are visible only under magnification will affect the electrical
performance of the connector. Use the following guidelines when evaluating
the integrity of a connector.
Look for Obvious Defects and Damage First
Examine the connectors first for obvious defects or damage: badly worn
plating on the connector interface, deformed threads or bent, broken, or
misaligned center conductors. Connector nuts should move smoothly and be
free of burrs, loose metal particles, and rough spots.
What Causes Connector Wear?
Connector wear is caused by connecting and disconnecting the devices. The
more use a connector gets, the faster it wears and degrades. The wear is
greatly accelerated when connectors are not kept clean, or are not connected
properly.
Connector wear eventually degrades performance of the device. Calibration
devices should have a long life if their use is on the order of a few times per
week. Replace devices with worn connectors.
The test port connectors on the network analyzer test set may have many
connections each day, and are therefore more subject to wear. It is
recommended that an adapter be used as a test port saver to minimize the
wear on the test set’s test port connectors.
Inspect the Mating Plane Surfaces
Flat contact between the connectors at all points on their mating plane
surfaces is required for a good connection. See
. Look
especially for deep scratches or dents, and for dirt and metal particles on the
connector mating plane surfaces. Also look for signs of damage due to
excessive or uneven wear or misalignment.
Devices with damaged connectors should be immediately discarded or
clearly marked and set aside for repair. A damaged device will in turn
damage any good connector to which it is attached. Determine the cause
of the damage before connecting a new, undamaged connector in the
same configuration.
