Cleaning the test tile
• Do not use any acetone!
The accuracy of the measurement can be
significantly impacted by using a dirty or
damaged test tile.
Since the surface of the test tile is highly
sensitive, cleaning must be undertaken with
great care.
To clean the test tile, use a new lint-free cloth,
dust-free lens paper or an optical cloth.
Apply only slight pressure as you clean and
make certain there are no large particles stuck in
the cloth that could damage the surface.
For dirt that is difficult to remove, use an pre-
moistened optical cloth. Then wipe the surface
with a dry optical cloth.
If the condition of the test tile seems doubtful
because of its appearance or measurement
errors, we will be happy to check it for you.
