5. When viewing alarm data, you can see it either in table or
graph form.
6. In graph form, five or more events are required for interval
trend data. When viewing interval trend or alarm trend
information in graph form, you have several options:
• You can choose which gas you want to graph
• You can choose the zoom level, or time interval, on the
graph. For alarm trend data, the zoom will always
correspond to a particular time division because alarm
data files have the same number of data points over the
same period of time (every five seconds for 15 minutes
before and 15 minutes after an event). For interval data,
the zoom feature shows greater detail relative to time.
Thus, an interval on the graph will depend on both the
length of the datalogging session and on the zoom factor.
