Defining Formulas
4–2
The first step in defining a formula is to select, by number (from 1–56), the
formula you want to define. The current formula number is listed in the
Formula #: box on the Config. Results menu (see Figure 4.1).

In selecting the formula(s) you want to define, and also when selecting
windows and gages to define, consider the following points:
•
Formulas are evaluated in numerical order: If you define formulas
which require results information from some other formula(s) from the
current inspection, make sure the formulas providing the required results
precede (in terms of numerical order) the formula requiring those results.
•
Formulas prevent the use of corresponding gage and window
outputs: Any formula you select and enable will disable the use of
results outputs from a corresponding gage or window, as listed in
Table 4.A, page 4–3. Note that gages 33–64 and windows 25–48 are
not listed in Table 4.A; they are not affected by the use of formulas.
Warning message: Whenever you enable a formula, a warning message
appears, identifying the corresponding tool that is being prevented from
driving an output (see “Enabling / Disabling a Formula” on page 4–38).
•
Formula results replace the results of the corresponding gage and
window in the results blocks: When you enable a formula, its
inspection results are listed in the results block, in place of the
corresponding gage or window results (as listed in Table 4.A, page 4–3).
Results blocks contain the comprehensive inspection results available by
transfer through the Color CVIM backplane, or through one of the Color
CVIM serial ports (see Appendix A for communications information).
When any formula is enabled, the Color CVIM module disables the
Range/Outputs box on the Range/Reference menu for the corresponding
tool (see “Setting Range Limits and Assigning Outputs” on page 4–41).
