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).
