6.1 Cleaning and Maintenance
6.1.1 Cleaning the Test Tile
Since the surface of the test tile is highly sensitive, cleaning must be under-
taken with great care.
To clean standards, use a new lint-free cloth, dust-free lens paper or an op-
tical cloth as included with the device.
Apply only slight pressure when cleaning, and ensure the cloth is free of
dust or other particles that could damage the surface.
For dirt that is difficult to remove, use a pre-moistened optical cloth. Then
wipe the surface with a dry optical cloth.
An exact verification is not possible unless the test tile is in perfect condi-
tion. If the condition of the test tile seems doubtful because of its appear-
ance or measurement errors, have it checked by the manufacturer.
6.1.2 Usage of Reference Tile
To ensure a precise instrument test, only original test tiles from the manu-
facturer should be used. Their surface must not be touched and must be
protected against scratches.
Due to environmental influences, however, the values of test tiles can
change over the course of time even if they are handled gently.
For this reason, have the test tiles checked by the manufacturer at regular
intervals (annual checks are recommended).
