Storage; Cleaning The Black Trap; Cleaning The Spectralon® Plaque - Datacolor 650 User Manual

Storage

Large temperature variations will affect the accuracy of your calibration, requiring
•
more frequent calibration. The calibration tiles should be stored in an
environment that simulates the temperature of the samples to be measured.
Prolonged exposure to sunlight or other sources of ultra-violet radiation will
•
cause the color of the tiles to change. The tiles should always be stored in a
protective case or container away from direct sunlight and environmental
contaminants.

Cleaning the Black Trap

The black trap should be kept dust-free. Dust accumulating in the black trap should be
blown out with compressed air.
Cleaning the Spectralon® Plaque
This is the white plaque used for transmission calibration and measurement. It is an optical
standard and should be handled in the same way as other optical standards. All efforts
should be made to prevent contaminants from contacting the surface of the plaque. We
recommend that you wear gloves when handling this plaque.
WARNING
Do NOT use Freon to air brush this plaque.
Cleaning Instructions
If the tile is lightly soiled, it may be air brushed with a jet of clean dry air or nitrogen. For
heavier soil, the material can be cleaned using the following procedure:
1. Sand the surface under running water
2. Blow dry with clean air or nitrogen, or allow the material to air dry.

Low reflectance Spectralon (<10% reflectance) should be dry sanded.
