Chapter 4

Defining Formulas

4–38

• Enter the desired formula name, by picking the appropriate keys on the

keyboard (see Chapter 5 in the Color CVIM User’s Manual for more

keyboard usage information). Pick Ret when the name is entered as

desired. When you do, this message appears:

Name restrictions: Names can contain up to seven characters, including

spaces. Any additional characters entered are truncated from the right.

Once you have defined a formula’s contents, you must then enable the

formula, in order for the formula to function as part of the configuration, and

in order to set range limits and assign outputs for the formula.

Define formula first: The Formula #: Disabled box for a selected formula

is itself disabled until the formula has been defined. Thus you cannot enable

a formula until you first define it (see “Defining a Formula” in this chapter).

To enable a formula:

• Pick the Formula #: Disabled box on the Config. Results menu (see

Figure 4.20).
