when plotted on-screen) is
plotted to verify that the
corrected spectrum
produces the same results
as the Certified 80%
Reflectance Standard.
Click “Close Report” to
continue. The correction is
automatically downloaded,
and is saved in the
Diagnostic Data Base.
The “Use Tray” correction
will be applied in real time
to all spectra taken with a
DCM where “Reference
Standardization” is
checked, and a tray is
used.
Next, perform a Reference Standardization in the “Use Iris” position. Be sure to select “Use Iris” in the
tray menu. Follow instructions for removal of tray, and insertion of the Iris Adapter. Repeat steps
given on pages 45-47 in the “Use Iris” position. The Reference Standardization will be stored for use
when scanning sample in the “Use Iris” mode.
NOTE: Perform Reference Standardization immediately after changing the spot
size, to have the proper reference correction loaded in the instrument.
Note that cleanliness of the sample window is very important when this program is run. If the
window is not extremely clean, the character of the window contamination will be imparted to the
Reference Standardization correction. Therefore, maintain a clean window at all times.
