Manually
sampled data A manually sampled data file is generated on the CF card when manual
sampling first occurs. Data is added to that file whenever manual sampling
occurs. A file is created every 100 data values. For operating instructions,
see section 4.4.
Report data Report data is stored in a report data file that is generated on the CF card
when report data is first produced. Report data is added to this file at the
report filing time.
Report File Division
At the set time, the MV stops recording to the current file and begins
recording to a new file. Files can be divided in the following ways.

Directory That Data is Saved To
You can specify the name of the directory that data will be saved to (the default
directory is “DATA0”). The MV will create the directory on the CF card and save data
to it.
Save Operation (when not using media FIFO)
If there is not enough free space on the CF card, internal memory data cannot be
saved. Before the internal memory data is overwritten, change CF cards and save the
data.
Save Operation (always retain most recent data file/media FIFO)
When the MV saves data files automatically, it can save files so that the newest data
files are always retained. With this method, the MV can be used continuously, and the
CF card does not need to be changed.
