Handling, Storage, Cleaning, and Making Connections
Observing simple precautions can ensure accurate and reliable measurements.
Handling and Storage
Before each use of the fixture/adapter, ensure that all connectors are clean. Handle all cables
carefully and store the fixture/adapter in the foam-lined instrument case when not in use, if
possible. Do not set connectors contact end down. Install the SMA protective end caps when the
fixture/adapter is not in use.
Cleaning
If necessary, clean the connectors using low-pressure (less than 60 PSI) compressed air or
nitrogen with an effective oil-vapor filter and condensation trap. Clean the cable threads, if
necessary, using a lint-free swab or cleaning cloth moistened with isopropyl alcohol. Always
completely dry a connector before use. Do not use abrasives to clean the connectors. Re-inspect
connectors, making sure no particles or residue remains.
Making Connections
Before making any connections, review the
“The Automotive Test Adapter Care and Handling
on page 7 then follow these guidelines when making connections:
• Align cables carefully
• Make preliminary connection lightly
• To tighten, turn connector nut only
• Do not apply a bending force to the cable
• Do not over-tighten preliminary connections
• Do not twist or screw-in cables
• When attaching instrumentation cables to the Automotive Ethernet Test Adapter, the test
adapter is recommended to be firmly held and that the instrument cable SMA connectors be
tightened to the equipment manufacturer's torque recommendations, normally use a 5/16-inch
open-end torque wrench for 5 in-lbs. Do not tighten past the "break" point of the torque wrench.
