point 4.1.2. . The eyepiece - cross-line divides
the field of view into 4 quadrants and marks
the field of views centre. To use the eyepiece
measuring plates the eyepiece - line disk ver-
sion is unscrewed, and the line plate is in-
serted in such a way into these that the engrav-
ing points downward to the object. When
connecting, the screen is again screwed in.
The eyepiece measuring plate has to align ver-
tical to avoid measuring errors because of the
oblique viewing onto the object (parallax)

plate. For calibrating, the division is turned to
the objective.  For direct linear measurement of
even objects these are placed on the object

on the object surface.

Several measuring programs are available.
For the use of these programs it is necessary

The measuring programs will be describe
