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.
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”.
This is a plot of the un-calibrated
sample fiber in the instrument. (The plot
color is cyan, which is made darker and
“heavier” here for readability. The
spectrum will be plotted in 1-pixel width
on the user screen.)
The wavelength scale is 800-2100nm,
the scale of this process instrument.
Click “OK” to plot a spectrum of the
Certified 99% Reflectance Reference.
