Creating Custom Runtime Displays

Note these additional considerations when setting Upper and Lower limits:

• The limits you set are for the Graph viewport itself, and therefore

encompass all variables plotted in the viewport. You cannot set Upper

and Lower limits ranges for each variable individually. Therefore, be

sure to accommodate the results of all variables you are plotting when

setting the Upper and Lower limits.

• Results which go beyond the Upper limit are plotted along the top of the

viewport. Results which go beyond the Lower limit are plotted along the

bottom of the viewport.

To set either the Upper or Lower limit:

• Pick the Upper or Lower box, as appropriate, on the Define Graph

menu, which causes the calculator pad to appear.

• Use the calculator pad to enter the range limit.

Upper box

Valid Range: The valid range for the Upper and Lower limits are

–32767 to 32767, and the difference between the two limits must not

exceed 32767. If you try to enter a number which is not valid, such as a

Lower limit value which is higher than the current Upper limit, the

calculator pad will flash the message – Value Out of Range.

Defining the Event

For each Graph viewport you define, you must specify the Event. In

defining the event, you are defining the conditions which must be met, upon

completion of an inspection, in order for the Graph viewport variables to be

updated. You define the event using the Event menu. See Chapter 8 for

more information on setting the Event.

For example, the default setting specifies that the Graph viewport is always

updated upon completion of an inspection. You can define other conditions –

you can specify that the viewport is updated every 100 inspections, for

example.
