Principles of Connector Care
Proper connector care and connection techniques are critical for accurate and repeatable
measurements. Refer to Table 5-1 for tips on connector care.
Prior to making connections to your analyzer, carefully review the information about
inspecting, cleaning, and gaging connectors. Refer to the calibration kit documentation for
detailed connector care information.
For course numbers about additional connector care instruction, contact Keysight
Technologies. Refer to “Contacting Keysight” on page 5-4.

Handling and Storage
Do Do Not
• Keep connectors clean
• Extend sleeve or connector nut
• Use plastic end-caps during storage
• Touch mating-plane surfaces
• Set connectors contact-end down
• Store connectors or adapters loose
Visual Inspection
Do Do Not
• Use a damaged connector - ever • Inspect all connectors carefully
• Look for metal particles, scratches, and dents
Connector Cleaning
Do Do Not
a. Cleaning connectors with alcohol shall only be done with the instrument’s power cord removed,
and in a well-ventilated area. Allow all residual alcohol moisture to evaporate, and the fumes to
dissipate, prior to energizing the instrument.
• Use any abrasives
• Get liquid into plastic support beads
• Try compressed air first
• Use isopropyl alcohol
a
• Clean connector threads
Gaging Connectors
Do Do Not
• Use an out-of-specification connector
• Clean and zero the gage before use
• Use the correct gage type
• Use correct end of calibration block
• Gage all
connectors before first use
Making Connections
Do Do Not
• Align connectors carefully
• Make preliminary connection contact lightly
• Turn only the connector nut
• Use a torque wrench for final connection
• Apply bending force to connection
• Over tighten preliminary connection
• Twist or screw any connection
• Tighten past torque wrench “break” point
