Gen er a l In for m a tion
To obtain optimum performance from this cable set, observe these simple precautions:
•
•
Flex and straighten the cables as little and seldom as possible.
Make connections carefully to avoid misalignment and connector damage or inaccurate
measurements.
•
•
Keep the connectors free of dirt and metallic particles.
If you must clean the connectors, try clean compressed air first. Do not use abrasives. With
a plastic swab, apply only liquid Freon (trichlorotrifluoroethane) as a solvent.
•
7 mm center conductor recession with collet removed: 0.0 to 0.003 inch.
