This event did not have an adverse effect on the health and safety of the public.

This revision reports that other factors affecting instrument uncertainty in addition to repeatability need to be considered for determining instmment accuracy. A more rigorous Design Criteria for Instrument Loop Uncertainty and Setpoint Methodology for use in establishing instrument setpoint and scaling values has been applied. Changes are indicated by revision bars.
