19. Data capture bar
(1) During data capture
Displays the elapsed time and the internal memory (SD1) and SD CARD usage status.
Elapsed time
Amount of internal memory and
SD CARD used
If, for example, 4 GB SD CARD is inserted and about 100 MB is used before data capture, the total
amount of memory is 4 GB, the amount of SD CARD used is about 100 MB, and the amount of SD CARD
remaining is about 3.9 GB. As time elapses during data capture, the amount of used SD 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 CARD. If the amount of remaining SD 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
Displays the display position, cursor position, and trigger position graphically.
