Data Graphs

Select the Graph icon to open a data graph for that parameter (Figure 4-23). Selecting a

parameter for graph view moves it to the top of the list. Select the Graph icon again to close the

graph for that parameter and return to a data list view.

Figure 4-23 Sample graph view

The icons that display on each data graph allow you configure settings for the selected graph only:

Triggers

Triggers establish threshold values, an upper limit and a lower limit, for recording a data snapshot.

A snapshot allows you to closely evaluate conditions that caused the triggering event.

When a snapshot is taken, the Scanner captures additional data after the trigger point is detected,

data collection pauses, and the buffered information is automatically saved as a movie. This gives

you a complete picture of what was happening before the fact, what occurred at the trigger point,

and what happened after the fact.

Data collection is paused following a trigger event. Select the Play icon to resume viewing live

data. A vertical line now appears on each of the data graphs to indicate the triggering point. The

trigger line on the parameter that triggered the snapshot is a different color than those on the other

graphs. This makes it easy to determine which parameter caused the trigger when triggers are set

for multiple parameters.
