Cleaning Tiles
The calibration tiles should be cleaned before each use. Wipe each tile clean with a soft, lint-free cloth.
A detergent, free of optical brighteners, fluorescent materials or photoactive dyes should be use as needed
to clear any oils, fingerprints or other deposits. Liquid dish detergent is a suitable detergent. The
detergent/water solution should be prepared as follows:
1 part detergent: 250 parts water
Use a few drops of the detergent solution to moisten a soft, lint-free cloth, and gently wipe the tile surface.
Rinse the detergent from the tile by wiping it with a cloth, moistened with clean water.
NEVER use abrasive cleansers, razor blades or other metal objects to remove dirt or foreign substances
from the calibration tiles. This will damage the surface.
Never immerse the tiles in water.
Tiles that have scratches, chips, abrasions or cracks must be replaced. Signs of wear and tear on the tile
surface will affect the accuracy of the calibration.
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.
Tile Storage
Large temperature variations will affect the accuracy of the 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.
