7.5.1 Text Format Stream Data Filenames

Text format stream data files can be configured to contain data
gathered over a predefined period of time (selected at the 'New
File Interval' parameter) – see Section 6.6.4, page 40. The
'Instrument Tag' is set in the configuration – see Section 6.1.1,
page 28.
Note. The time and date are formatted according to the
date format set in 'Common Configuration' – see Section
6.1.3, page 29.
Once configured, the filenames for each archive file are assigned
automatically.

Filename extensions are assigned according to the data type

In addition to creating new stream data files according to the
'New File Interval', they are also created in the following
circumstances:

If the analyzer's power is lost then restored.

If the analyzer is taken offline and the archive media
removed, replaced or refitted.

If the analyzer's configuration is changed.

If one of the current files exceeds the maximum
permissible size.

When the daylight saving period starts or ends.
Note. The analyzer's internal clock can be configured to
adjust automatically at the start and end of 'Daylight Saving
Time' periods.
When one of the above conditions occurs, new stream data files
are created for each enabled group and the file extension index
on each new file is incremented by one from the previous file.
Example: If the original file had an extension of .D00, after one
of the above events a new file is created with the same filename
but an extension of .D01.
