maintenance necessary to keep the instrument functioning properly and provides tests to
assess performance.
Cleaning the ColorFlex EZ Citrus

directly on the instrument.
Maintaining the Instrument Standards
Before standardizing, inspect the calibrated White Tile and Black Glass for dust and fingerprints.
Do the same for the diagnostic Green Tile prior to running the Green Tile Test. Keep the
calibration tiles in the carrying case when not being used. If a tile is lost or damaged, contact
HunterLab as described in
WHEN YOU NEED ASSISTANCE concerning replacement.
Clean the tiles using a soft nylon bristle brush and a solution of warm water and a laboratory
grade detergent such as SPARKLEEN. Rinse the tiles in a stream of warm tap water. Blot them
dry using a clean, non-optically brightened, lint-free paper towel.

and may be ordered from them using catalog number 04-320-4. One tablespoon
of SPARKLEEN should be added to every gallon of water.
