Interval Trend Data
Gas concentrations are logged over five minute time intervals in the interval
trend data files. Events are saved when they occur. The data may be
viewed in table format, as seen in the following figure, or graph format.
The above information was obtained after the Model GX-2001 recorded
gas concentration levels in the monitoring area. The unit was then placed in
the Data Logging/Charger Station and the information stored in the unit’s
memory was down loaded to the computer. From the main window of the
Data Logging Software, the Data Icon was “clicked” (using the computer
mouse) to display the main Data window, from which this screen was
displayed.
For a given data session (interval data), there must be at least five
scheduled logs (every five minutes) for the data to be seen in graphical
form. If an interval data session has fewer than five scheduled logs, as in
Figure 1 above, the graph button is not available for selection.
Note that the data count shown when you have selected an interval data
file, as in Figure 1above, can be more than five if you have events, such as
