There are a number of ways that the logging session can end:
1. When the logger memory becomes full, and data rollover was not selected during logger setup, the logger will automatically stop logging and enter the idle state.
2. If the logging session was started by closing the logger door (Logging Starts When Door Is Closed, Stops When Door is Opened option was selected from the setup screen), the logging can be stopped by opening the door. When the door is opened, the logger will flash the status light red for 10 seconds. If during this period the door is closed again, the logging will not stop. This helps preventing accidental stoppage of logging.
3. Selecting End Logging from the Logger menu.
4. If the logger detects a low battery condition, the logging will stop and the logger will enter the low battery state.
5. If the battery is removed from the logger, logging will stop. No data will be lost.
Once the logging has ended, it cannot be resumed without erasing the logged samples stored in the logger memory.
