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.
Once configured, the filenames for each archive file are assigned automatically.

Note. The time and date are formatted according to the date format set in 'Common Configuration' – see Section 6.1.3, page 29.

Note. The analyzer's internal clock can be configured to adjust automatically at the start and end of 'Daylight Saving Time' periods.
Table 7.4 Text Format Stream Data Format
Filename extensions are assigned according to the data type archived, as detailed in Table 7.5.
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.
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.
