Hi All,

The following  is a very interesting paper coming from
GORE-TEX microwave test cables : 

                       DO

      HANDLING & STORAGE

1) Keep connectors clean
2) Extend sleeve or connector nut
3) Cap when not in use
4) Store in provided box
5) Unroll any cable loops

       VISUAL INSPECTION

1) Inspect all connectors-including
     mates-carefully before every 
     connection

2) Look for metal particles, debris,
     scratches, dents, loose pins,
     jammed  collects, worn plating, 
     damaged nuts

                 CLEANING

1) First try compressed air only
2) Use pure isopropanol with cotton
     swabs

3) Clean connector threads
4) Dry with compressed air

                 GAGING

1) Gage all connectors before first use
    and periodically thereafter 

2) Clean and zero the gage before using

          MAKING CONNECTIONS

1) Align connectors carefully
2) Make preliminary connection lightly
3) Turn connector nut only to tighten
4) If possible, use a torque wrench for
     final connection

5) Use proper torque
6) Loosen and re-torque periodically
7) Prevent rotation of connector bodies 

------------------------------------------------------

                    DO NOT

         HANDLING & STORAGE

1) Touch mating plane surfaces
2) Set connectors contact-end down
3) Allow free cable end to drop
4) Store loose in drawer
5) Pull out cable loops
6) Use cables to reposition equipment

           VISUAL INSPECTION

1) Use or connect to a damaged or 
     dirty connector-ever 

                    CLEANING

1) Use any abrasives, chlorinated solvents,
    or lubricants

2) Get isopropanol onto plastic support beads
3) Blow into connectors
4) Tap connectors to remove debris

                      GAGING

1) Use an out-of-spec connector
2) Hold gage by housing-use plunger barrel only

     
          MAKING CONNECTIONS

1) Apply bending force to connection 
2) Overtighten preliminary connection
3) Connect by rotating the famale 
4) Tighten past "break" point of torque wrench 
5) Snap wrench more than once
6) Approach break point rapidly
7) Use an end wrench to tighten
