• Vision will plot the spectrum of the ceramic reference, click OK; plot the Reflectance
Reference spectrum, click OK; and plot the correction spectrum, click OK. Correction

• Click Close Report.
• Choose Diagnostics/Reference Standardization/Reference Standardize Project to Reference
Standardize the current project.
• Move to File/Project/Convert. The software will ask if you are sure. Answer YES. Remember
this is not reversible. Click OK
• If your project data was collected from 1100-2500nm it must be expanded to full range of
400-2500nm as all XDS instruments scan full range. Go to File/Project/Expand to expand to
full range. If the original data was collected from 400 to 2500 nm, this is not necessary.
• Now you can proceed to go through Sample Selection and Regression to develop a new
calibration equation using the standardized, converted, expanded data. Frequently the same
math treatments and regression techniques can be used.
• Create a new Operations Method using the Reference Standardized DCM and the new
Calibration Equation.
3.13.2 Transfer of Library on the same computer
Before leaving the System II instrument, open the project from which you developed the Library that
you want to convert for use on the XDS instrument:
• Go to Configure/Options and select the option for Reference Standardization followed by
Acquire/Connect
• At the Select Data Collection Method dialogue box, create a new DCM for your instrument.
The box for Reference Standardize should be active. Select that DCM followed by OK.
• Move to Diagnostics/Reference Standard/Create Reference Standard
• Vision prompts for the ceramic reference. Position the ceramic reference and click on OK for
scanning to begin.
• Vision requests positioning of the 80 % Reflectance Reference. Position the correct reference
standard for your instrument and click OK to scan the Certified Reference.
• Vision then requests the Standard File for the Certified Reference. This file is on the diskette
accompanying the Standard(s) and may be copied to the Vision directory for ease of use.
Insert the diskette into drive A and access the file. The file is contained in RSSxxxx.da Click on
the file, then click Open.
• Vision will plot the spectrum of the ceramic reference, click OK; plot the Reflectance
Reference spectrum, click OK; and plot the correction spectrum, click OK. Correction
