14. Slide the sample drawer back to the normal
position.
15. Install the Smart Probe module back onto
the monochromator, and tighten the
release handle.
16. Place the Smart Probe into the reference
position.
17. Warm up the instrument thoroughly. Run
Performance Test to verify proper
operation.
(See section 7.2 for test instructions and
information.)
18. Run Reference Standardization to create a
new calibration for the newly-cleaned
internal reflectance reference.
(See section 7.1 for test instructions and
information.)
Always protect the Certified 99% Reflectance Reference from contamination:
1. Always clean the tip of the Interactance Reflectance probe thoroughly before performing
Reference Standardization.
2. Store the Reference Standard in its protective case between uses.
3. Avoid any introduction of dirt or contaminants into the surface of the Reference Standard.
Dirt and sample carryover will change the optical characteristics of the standard, which will
then affect how the instrument reads samples.
The quality of the instrument spectra depend upon proper Reference Standardization. This XC-1200
Reference Standard has been calibrated on a Master Smart Probe instrument which reads on a scale
of true reflectance. The calibration for the Reference Standard is the linkage back to traceability, and
is essential for good method transfer with the Smart Probe.
