Care and Handling of Precision Connectors
Accuracy Considerations

Handling Precision 3.5 mm Connectors
• Precision 3.5 mm connectors must be handled carefully if accurate
calibrations and measurements are to be obtained.
• Store the devices in the foam-lined storage case when not in use.
• Avoid bumping or scratching any part of the mating surfaces.
• Be careful to align the center connectors.
• Check the alignment carefully before tightening the connector nuts.
• Use a torque wrench for all final connections in order to avoid
overtightening.
• Support the devices being used in order to avoid vertical or lateral force on
any connectors. This precaution is critical when using the airline, 6 cm "L",
or cables.
When Disconnecting Devices:
• Do not rock or bend any connections.
• Pull the connector straight out without unscrewing or twisting.
• Before storage, screw the connector nut all the way out to help protect the
surfaces, and use the plastic caps provided. These plastic caps can be taken
off easily by unscrewing, rather than pulling.
CAUTION Do not use a damaged or defective connector. It will damage any good
connector to which it is attached. Throw the connector away or have it
repaired.
A connector is bad if it fails either the visual or mechanical examinations or
when an experienced operator cannot make repeatable connections. The time
and expense involved in replacing channel connectors warrants considerable
caution when any connector might be less than perfect.
If any doubts exist about a connector, call your Hewlett-Packard representative.
Hewlett-Packard field offices offer limited professional advice and have access
to the factory for information.
