Step 2: Configure the Sensor
When you are ready to begin the study, click on the Start button to:
Enable ash storage
Save the selected settings to the sensor
Synchronize the sensor date and time
Erase stored data from both SRAM and ash memory
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 bottom of the screen.
Note
If the start time does not coincide directly with the beginning of an interval, the first
interval in memory will contain a partial aggregation of data.
Interval Data Buer Status
As soon as the study begins, the View Interval Data Buer Status window will appear. is
window shows you how much of the guaranteed onboard storage space is lled with inter-
val 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.
e blue bars indicate the amount of memory that contains data (see Figure 7.2).
