14. File name display
(1) During data capture
A capture file name is displayed during capture.
* If the ring capture setting is ON, a file name displayed during capture ends with "_RINGx" (x represents
a number) but the actual file name does not include "_RINGx".
In the above figure, if the ring capture is set to ON, the file name during capture will be displayed, for
example, as "<MEM>091225\091225-130620_UG_RING4.GBD" but the actually created file will be
"<MEM>091225\091225-130620_UG.GBD".
* Refer to page 3-26 for details on the ring capture setting.

Amount of memory used
If, for example, 256 MB USB memory is inserted and about 96 MB is used before data capture, the total
amount of memory is 256 MB, the amount of memory used is about 96 MB, and the amount of memory
remaining is about 160 MB. As time elapses during data capture, the amount of used memory 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 memory. If the amount of remaining memory 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
