Both Manage and Download buttons open it.

The dialog shows all records which have at least one file on the active disk(s): On analyzer(s) or on PC USB.

The preselection buttons have been split into 3 categories:

• All / None: for backup or disk cleaning.
• Downloadable: Select records which have corresponding project & measurement in the Project Manager.
• Orphans: Select records which haven't any corresponding project & measurement in the Project Manager.

NB: Preselection buttons do not select partial records. i.e. one or more disks are not connected. Use manual selection to download an incomplete record. Warning this is a definitive action. It will be impossible to add missing files later.

The Target choice allows choosing the download destination:

• Automatic: add each signal file in the Project/Measurement used for its acquisition. Note that records without Project/Measurement correspondence in the Project manager will be added in the current project.
• Project: add the signal files in the selected project regardless of original project.

Signal properties

The properties of recorded signals includes location and traceability.

The analyzer(s) which have been used to record the signal are memorized in the column Acquisition Front-end. It is the easy to identify records that may be altered by a faulty input.

• Same thing regarding the used (Mobi-) disks.
• The information is saved with the measurement itself. They are available even if the analyzer or the disk is not connected.
• The Signal on disk indicates the presence of record file on the connected disks: Yes/No or a question mark when the disk is not connected.
