Determining Expected System Performance

Improper connection techniques and contact surfaces can degrade measurement accuracy.
Proper connection techniques include using a torque wrench with proper torque limits,
ensuring that the connector pin depths meet specifications, ensuring that the center
conductor of sliding loads is properly set, and observing proper handling procedures for
beadless airlines.
Contact surface errors are caused by improper cleaning procedures, scratches, worn
plating, and rough seating.
If proper connection techniques and connector care is observed, Table 10-1 provides an
indication of connector repeatability.
