A Caring for Connectors
62 Keysight N4000/1/2A Operating and Service Manual
If a connector shows deep scratches or dents, particles clinging to the mating
plane surfaces, or uneven wear, clean it and inspect it again. Damage or defects
like dents or scratches, which are deep enough to displace metal on the mating
plane surface of the connector, may indicate that the connector itself is damaged
and should not be used. Try to determine the cause of the damage before making
further connections.
Precision 7 mm connectors
Precision 7 mm connectors, among them APC-7
®
connectors, should be
inspected visually with the center conductor collets in place, and whenever the
collet has been removed. See Figure A-1 .
The collet itself should be inspected for edge or surface damage and for any signs
that the spring contacts are bent or twisted. If they are, replace the collet. When
the collet has been re-inserted, verify that it springs back immediately when
pressed with a blunt plastic rod or with the rounded plastic handle of the collet
removing tool. Never use a pencil or your finger for this purpose.
