Selecting the Variable Tool
You must select the specific tool whose results are plotted in the Graph
viewport – either a gage, a window, or a formula.
To select a gage, window, or formula as the variable tool:
•
Pick the appropriate box on the Define Graph Var. menu – Gage,
Window, or Formula . This causes the calculator keypad to appear.
•
Use the calculator pad to enter the number for a specific gage, window, or
formula.
Note: You must have the MATH–PAK option package (Cat. No.
5370–MPK) installed in order to successfully use any
Formula selection.
Calculator Pad
Window box
Value Out of Range: If you try to enter a number which is not valid,
such as a gage number 35 (there are only 32 gages), the calculator pad
will flash the message –
Value Out of Range. If this happens, pick an
appropriate number, and then pick the Enter key again.
Defining the Graph
After defining the variables, you next define the graph, using the Define
Graph menu. This menu appears when you pick the Define Graph box.
Using the Define Graph menu, you can:
•
Set the Upper and Lower limits of the Graph viewport (all variables will
then be plotted in the viewport relative to these limits).
•
Define the Event, or circumstances under which the graph variable
plottings are updated.
