General Exterior Cleaning
The case, front panel, sample holder and surface of your instrument should be kept clean and
free of dust. This can be accomplished by dusting these components with a lint-free cloth.
General cleaning should be performed on a weekly basis or more often if the unit is used in a
dusty operating environment.
Cleaning the Transmission Compartment
Use clean, dry compressed air to blow any dust, dirt or other contamination out of the
transmission compartment.
Cleaning the Calibration Tiles
Ceramic standards (calibration tiles) are widely used in color science as standards of reflectance
factor. Their principal virtue is the stability of their reflection properties. If they are to serve their
intended purpose, it is necessary that the surfaces of these tiles be maintained in a stable
condition. The cleaning of any precision optic risks degrading the surface. Therefore, the need for
cleaning should be minimized by returning the tile to its storage case or covering it with a
protective bag when it is not in use. If cleaning is required, the following procedure is
recommended.
Materials Required
•
Isopropyl alcohol, Glass cleaner, Lint-free wipes, and Distilled water
To remove dust, lint, and invisible particles, proceed as follows:
1.
Place the tile on a stable surface and hold the tile by its edges.
2.
Spray a small amount of Isopropyl Alcohol onto a portion of a lint free wipe, then wipe with a
circular motion making sure to clean the entire surface. Use a dry portion of the wipe to wipe
the surface of the tile until dry. Discard the wipe.
3.
Spray a liberal amount of glass cleaner onto the surface of the tile. Using a clean lint-free
wipe, allow the wipe to become saturated with the glass cleaner on the tile, then wipe the tile
in a circular motion, making sure to clean the entire surface of the tile. Discard the wipe.
Excess glass cleaner will remain on the tile. Quickly move to the next step before it dries.
4.
Hold tile vertically and spray a liberal amount of distilled water onto surface of tile allowing to
run off, rinsing off the remaining glass cleaner. Dry the surface using a lint-free wipe in a
circular motion. Discard the wipe.
Cleaning the Black Plastic Blocking Panel
Dust on the black plastic blocking panel can be very tightly bound by static electricity. To remove
the dust, blow canned air across the surface.
Cleaning the Sphere
NOTE
: Do not touch the inside surface of the sphere or stick anything into the sphere.
The sphere should be inspected for any debris that may be present. Follow the procedure to clean
the sphere.
1.
Open the sample door to the fully open position.
2.
Use clean, dry compressed air and blow short bursts into the sphere. This should remove any
dust, dirt or other contamination off the inside surface of the sphere.
