3.2.4 Scrapers, Lower Measurement Carriage
In addition to the scrapers, the lower measurement carriage has scrapers on both sides
of the linear guide. The abrasion from the object being measured falls into a dirt pan and
is pushed by the scrapers on both sides to the respective end of the measuring system.
The abrasion falls through the measuring system there.

3.2.5 Master target
In the first step a temperature-stable master target is pneumatically swiveled into the
parking position; it is used for calculating the measuring gap. At the end of this measure-
ment, the master target is swiveled back pneumatically into its home position.
A reference measurement is also made. Here, the entire traverse width is traced with a
target of known thickness to detect errors and unevenness. These values are stored and
used by the measuring systems as a zero and error curve.
