Chapter 4

Defining Formulas

4–41

Formula name copied: The formula name is copied as well as the formula

contents. When you copy a formula, you may want to change the name of

the formula at the destination, or at the source, as appropriate.

Name and contents copied: Only the formula contents and formula name

are copied; the range limits and output assignment(s) are not copied.

Copying an undefined formula: If you copy an undefined formula (one

which has no contents currently entered), when you paste the formula to a

formula which has already been defined, you will delete the destination

formula, and this message will be displayed:

Example Copy and Paste

To copy the contents of formula 1 to formula 2, you would do the following:

• Pick the Previous or Next boxes, or use the Jump box, as required to

select formula 1.

• Pick the Copy box to select formula 1 as the source. The Paste box will

display the number of the source formula – in this case, the box reads

Paste 1, for formula 1 (see Figure 4.21, page 4–40).

• Pick the Next box to select the destination formula – formula 2.

• Pick the Paste box to place the source formula contents into the

destination formula.

The Paste box retains the source formula listing (1, in this case) until you

use the copy box to select another source formula. The source formula

designation is updated if and when you select a different source formula.

Once you have defined a formula’s contents, and have enabled the formula,

you can set range limits and assign outputs for the formula. The usage and

function of range limits and output line assignment for a formula are

identical to that of inspection gages and windows (see also the chapter on

range limits and output lines in the Color CVIM User’s Manual).

The term range limit refers to the tolerance limits you set for the formula

results. You can specify High and Low FAULT RANGE limits, and/or the

High and Low WARNING RANGE limits, for the formula results.
