Save Operation (Always retain most recent data file/media FIFO)

When the DX saves data files automatically to the CF card, it can save them so that

the newest data files are always retained. With this method, you can use the DX

continuously, without changing the CF card.

For the setting procedure, see section 6.2 in the User’s Manual.

• Operation

When the DX is saving data to the CF card, if there is not enough space to save a

new le, the DX deletes the oldest les and then saves the new le. This operation is

referred to as FIFO (rst in rst out).

•

FIFO is only used when the following les are saved automatically

. When les are

saved using other methods, FIFO is not used.

Display data les, event data les, report data les, manual-sampled-data les, and

snapshot data les.

• Files subject to deletion

All les in the destination directory, except for the ones listed below

, are subject to

deletion.

Files not subject to deletion: Hidden les, read-only les, and les contained within

subdirectories in the destination directory.

• The most recent 1000 les are retained. If there are more than 1000 les in the

destination directory

, even if there is enough free memory, older les will be deleted

so that the le number remains at or below 1000.

• When there are more than 1000 les in the destination directory

, one or more les

are deleted before the new le is saved. The number of les does not remain at or

below 1000 in this case.
