Metrohm NIRS XDS Interactance OptiProbe Analyzer - Manual (Page 55)

Vision requests a “Standard File”. This is provided on
a mini-CD, packed in the wooden box with the
standards.
Insert this mini-CD into the appropriate drive, select
that drive in the dialog box, and click on the
RSS1xxxx.da file as shown. (The serial number will
be different, of course.) Click “Open”.
The standard file is “NSAS File” format, which refers
to an older software package. This format is used
where it aids in file transfer.
For Number of Replicates, enter “4”. Because the
OptiProbe has a small sampling window, the
replicates assure better consistency.
Click on “OK”.
Vision will begin to take an instrument reference
scan, if the instrument is operating in Reference
Standardized mode. The red progress bar at the
bottom of the screen indicates status.
If operating in Reference Standardized mode, Vision
requests the 99% standard from the set.
(If not operating in Reference Standardized mode,
Vision requests the 80% standard, which is used in
place of the internal instrument reference.)
