trend file can always be graphed regardless of the number of logged
points.
When viewing alarm trend data in graph format, you have several
options:
• You can choose which gas you want to graph
• You can choose the zoom level, or displayed time interval, on the
graph. The zoom feature shows greater detail relative to time. Thus,
the length of a time division on the graph will depend on both the
length of the datalogging session and on the zoom factor.
• When selected, the Cursor feature allows you to display the gas
reading and log time for each data point in the alarm trend file. As
you use the left and right arrow buttons on your keyboard to move
the cursor across the graph horizontally, readings at specific log
times are displayed. Use the up and down arrows on the keyboard
