19. Data capture bar
(1) During data capture
Displays the elapsed time and the SD memory card usage status.
Elapsed time
Amount of SD memory card used
If, for example, 4 GB SD memory card is inserted and about 100 MB is used before data capture, the
total amount of memory is 4 GB, the amount of SD memory card used is about 100 MB, and the amount
of SD memory card remaining is about 3.9 GB. As time elapses during data capture, the amount of used
SD memory card increases and the amount of remaining memory decreases.
The remaining time for data capture shows a length of time during which data capture is available with the
amount of remaining SD memory card. If the amount of remaining SD memory card is more than 2 GB,
however, this part shows remaining time during which data capture is available with one 2 GB file.
* Remaining time more than 99999 hours is displayed as "++++:++:++".
(2) During data replay
