Select Configure, Options from the menu

bar.

The menu shown at right is the set of

selections. A brief explanation follows:

Instrument must stabilize before data
acquisition:

This prevents spectral acquisition if the
instrument is cold.

Performance Test must pass before
data acquisition:

This prevents the user from taking data
on a non-functional instrument.

Run performance test after
wavelength linearization:

Forces user to run test sequentially. This is
not necessary with XDS.

Use Auto-Linearization:

Maintains correct wavelength registration
automatically, using internal wavelength
materials to keep instrument in precise
adjustment over time.

Reference Standardization:

Used to create a virtual 100% reflectance
or transmission reference, using a
photometric standard. This is explained in
the next section. Required for Calibration
Transfer.

Blank Correction

Does not apply to this instrument configuration. Leave unchecked.

Master Standardization

This method is not used with XDS. Do not select.

Use Instrument Calibration (XDS only)

This is a method to adjust the instrument wavelength profile to an external, traceable
wavelength standard. It is checked as a default for XDS. Required for Calibration Transfer.
