Vision requests that the Certified Reflectance
Reference be scanned.
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
NIRSystems master instrument.
Place the Certified 99% Reflectance Reference onto
the Reflectance Probe, hold in place, and click on
“OK”.
Note the 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.
