NOTICE
Cleanliness of plate and glass components
To ensure proper measurement, make sure that the measuring plate and the
components are free of all contaminants (particularly the fiducials in the corners of the
glass components).
The glass components should be cleaned with glass cleaning agent (e.g. Viss universal
from Lever)
► Clean the measuring plate and apply the double-sided adhesive foil as described below.
NOTICE
Applying the foil without air bubbles
► Make sure that the foil is applied without air bubbles, particularly in the area around
the line markings on the measuring plate.
Applying the foil
► Remove the narrow strip of protective paper from the foil (Figure 3-3).
