CHAPITRE 3. GETTING STARTED
Recording file size or duration limit
In addition to triggers, it is also possible to add a limit to the recording file. This can be used, for example, to avoid
obtaining a very large file if the event associated with the end-of-recording trigger is never reached.
If the "Enable record file size limit" checkbox is disabled, the DAS records for the maximum duration (available
disk space).
If the box is checked, the user can configure the limit in 2 different ways:
• Memory size on disk
if the channel configuration changes (addition or deletion of measurements, change
of recording frequency), the size limit will be retained and its equivalence in recording duration will be re-
evaluated
• Recording duration
if the channel configuration changes, the recording duration will be retained and the
size of the recording file will be reassessed.
• Please note that if you add measurements or increase the recording frequency, the corresponding file size
will increase while retaining the recording time. The system will then limit the size to the available disk space,
and the recording time cannot be retained.
User information
The user can add a certain amount of information to be included in the registration file:
• Author
• Department
• Project
• Subject
• Comments
Each of these fields is a character string. They can be left empty, but this has no influence on the file name or the
recording sequence.
