Important: Valve spanning procedures in chapter 9 require unselected
valves be driven at signal levels representative of a normal production run.
We discuss process considerations that impend changing these values in
chapter 10. Changing these values may require you to re-span your valves.
Record all set-output values for unselected valves in worksheets 7.A – 7.D.
