Use Window Correction (XDS only):
This feature is used only with XDS Process instruments that operate with Transmission Pair probes.
Do not select.
Instrument matching (method transferability) requires that Reference Standardization and Instrument
Calibration be selected, and that Certified Standards are used on a regular basis to maintain
calibration.
These calibrations should be run when indicated by Photometric Test (Reference Standardization) or
Wavelength Certification (Instrument Calibration.).
Some of these selections are spectroscopic
calibrations, and are used to apply corrections
to the instrument to minimize differences
between units of the same configuration.
The correction programs are accessed from the
Diagnostics menu bar, shown at right. The
diagnostic steps are explained in the sections
that follow.
Before performing Diagnostic tests, click on “Acquire, Connect”, and establish a DCM for reflectance
analysis. The DCM shown is typical – note that the “Detector” is Reflectance.
Once the DCM is established, give the reflectance detectors time to stabilize. This may take 10-15
