It will take several seconds before the study actually begins. When the study
does begin, the start time will be displayed in the status bar at the boom of the
screen.
Note
If the start time does not coincide directly with the beginning of an
interval, the rst interval in memory will contain a partial aggregation of
data.
Interval Data Buffer Status
As soon as the study begins, the View Interval Data Buer Status window will
appear. This window shows you how much of the guaranteed onboard storage
space is lled with interval data. If the data collection setup process has just
nished, the storage space should be mostly unused. If you leave this window
open, the status will be updated every 30 seconds. The blue bars indicate the
amount of memory that contains data (see Figure 7.2).
