The Certified 99% Reflectance Reference is shown.
It comes with a diskette, which must be used
during Reference Standardization on Interactance
Reflectance channels.

The set is named RSSPxxxx, which includes the
R99Pxxxx Certified Reflectance Standard, and the
“Standards” diskette. The Standards diskette
contains a certified NIR spectrum, taken on the
Metrohm master instrument.

Place the Certified 99% Reflectance Reference
onto the Reflectance Probe, hold in place, and
click on “OK”.

NOTE: Orientation of the standard.

Vision prompts the user to rotate the Certified
99% Reflectance Reference. Rotate in 90-degree
increments, for a total of four scans, at the
prompts. The four spectra are averaged, and the
averaged spectrum is used for Reference
Standardization. This minimizes the directional
effects of the standard, to provide best
consistency.

Vision requests the Standard File for the Certified
99% Reflectance Reference. This file is on the
diskette (or Mini-CD) packed with the standard,
and may be copied to the Vision directory for ease
of use. It is shown here on the D: drive, on a Mini-
CD.

The file is named “RSSPxxxx.da”. Click on the file,
then click “Open”.
