Tile Handling and Cleaning
Handling Tiles

Handle calibration tiles with extreme care. Do not drop them, or scratch the
glazed surface.

Always use the edges to grasp the tile.
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.
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.
