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.
