Left side of microscope
The upper key is pressed to increase the
magnification, the lower key to decrease the
magnification. Short pressure on the key
switches to the next lower or higher
magnification. If you sustain the key for longer
then 0.3 sec., the display jumps to the next
higher or lower magnification every 0.5 sec. The
nosepiece is not actually turned until you
choose a specific magnification by releasing the
key. All you have to do to switch from any higher
magnification down to survey magnification, for
example, is to sustain the lower objective key for
approx. 3 sec. The selected objective is turned
into the light path in the direction that involves
the shortest travel distance.
n. b.:
When installing the system (see “Individual user
adjustments”, p. 48) it is possible to operate
the objective change function on the right side
of the microscope instead of the left.
Motorized objective nosepiece
The electronic nosepiece control allows easy
and safe change of the objective magnification.
Objectives are changed with 2 push buttons
(objective changing keys) which are easily
accessed behind the focusing handwheel on the
left of the microscope.
