Note that Reference Standardization must have been selected under Configure, Options, for this to
take effect. Once selected, a new Data Collection Method (DCM) must be created for Reference
Standardization to be checked in the DCM box. It is not applied to a DCM retroactively.
When Reference Standardization is selected under Configure, Options, a Reference Standard must be
created for every sample channel that is “Used” even if the probe style is not Interactance
Reflectance. See the sections on these probes for full information.
Follow these steps to create a Reference Standardization on channels using Interactance Reflectance.
First select the channel. From the menu bar, click
on Acquire, then Select Channel. Use the spinner
to select the correct channel, then click on “OK”.
This must be performed for each channel. Always
verify the channel before proceeding with the
test.
Select Diagnostics,
Reference Standard,
Create Reference
Standard.
Vision takes an instrument
reference scan.
The XDS instrument has an
internal reference fiber,
which is selected for this
operation.
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.
