The correction spectrum
represents the amount of
spectral correction
required to provide a
virtual 100% reflectance
reference at each data
point.
Click “OK” to plot the
correction spectrum in the
next window.
A final spectrum (green
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 correction will be
applied in real time to all
spectra – in the “Use Tray”
mode -- taken with a DCM
where “Reference
Standardization” is
checked.
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 correction. Therefore, maintain a clean window at all times.
