The logger is configured to start logging on a particular date/time. The display counts down in
days, hours, minutes, and seconds until logging begins. In this example, 5 minutes and 38 seconds
remain until logging begins.
Displays when the logger is currently logging.
The logger is configured to stop logging when memory fills. The memory bar indicates the
approximate space remaining in the logger to record data. When first launched, all five segments in
the bar are empty. In this example, the logger memory is almost full (only one segment in the
memory bar is empty).
The logger is configured to never stop logging (wrapping). The logger continues recording data
indefinitely, with newest data overwriting the oldest data. When first launched, all five segments in
the memory bar will be empty. In this example, the memory is full (all five segments are filled in)
and new data is overwriting the oldest data. This continues until the logger is stopped or the battery
runs out.
