operation mode, see the math tool example, Example: Using a Single
Math Tool to Generate Multiple Results, on page 7–144).
•
Loops –– This field enables you to set the number of results to produce
when
Multiple operation is selected.
•
Nominal –– When you pick this field, the currently selected and
configured math tool performs a test operation, and the results data from
the operation appear in this field. The type of results data depends on the
formula and the selected operation (
Single or Multiple ). The initial value
is 0.000.
•
Formula –– The button accesses the math tool’s formula entry
keyboard, which is used to configure all formulas.
•
Ranges –– The button accesses the range–selection panel, which
can be used to define range limits for formula results.
•
Values –– The button is active only when the Multiple operation
is selected. When you pick this button, the Math Values panel appears
and lists one or more results values from the formula.
•
P&P Name –– The button accesses the Pick & Place panel,
which enables you to reposition the math tool name within the image.
•
Done –– When you pick the button, the system exits back to the
toolset edit panel.
NOTE: If an “illegal” name is entered (such as “ tin ” for the trig function
“ tan ”), or an “illegal” math sequence used (such as “ {Tool 1} + ”), a “ Bad
formula. ” message box will appear on the screen.
A math tool can be selected when the toolset edit panel is on the screen.
Starting from the main menu bar, the selection path to this panel is as
follows: Editors
→ Configuration → Setup → Tools. This selection path
is shown by the example in Figure 7.1 (page 7–2).
Here is a summary list of the basic math tool configuration steps, listed in
their normal order of performance:
1. Select math tool operation mode.
2. Select number of loops (Multiple operation).
3. Select formula keyboard.
4. Configure formula.
5. Learn nominal value.
6. Check values (Multiple operation).
7. Select ranges.
8. “Pick and place” math tool name.
