Torque setting: The torque has already been
optimally adjusted at the factory, but you can
change this setting as follows: move the lower
control (43.2) to the "long" position (see above).
Push the upper control (43.1) upwards.
Loosen the 1.5 mm Allen clamp screws (43.3 or
43.6), using either an offset screw key (1.5 mm
socket-head) or one of the two centering keys
(1.4 or 1.5). The threaded hole for the clamp
screw of the upper ring is at an angle.
After 1 – 2 rotations of the rings (43.4 or 43.5) the
x and y adjustment can be set tighter or looser,
respectively; move the x- and y-adjustment as
far as the stop if necessary. When you have set
the torque, fix the ring with the clamp screw
(43.3 or 43.6) and pull the upper control down.
Stage rotation: Loosen the clamp screw (12.6).
Pol rotary stage*, Pol object guide*
The specimen is fixed to the stage either with
two sp ring clip s or preferably, with the Pol 2
multi-format object guide (Fig. 13). For specimen
slides with a width of approx. 26 mm (1''), swivel
out the metal plate (13.2) and insert the object as
shown in the illustration. If ordinary specimen
slides with a width of 26 mm are inserted
vertically to this, the movement range of the
object guide of about 30 x 40 mm is not fully
utilized. The supplied set of pairs of clickstop
buttons enables clickstops at intervals of 0.1,
0.3, 0.5, 1 and 2 mm. These are replaced by a
strong axial pulling movement. Note the correct
orientation of the catch pins inside when
pushing on the new clickstop button. The stop
screw on the underneath must be moved
inwards by about 2 mm to limit the vertical travel
on smaller types of microscope.
The two verniers permit angle measurements
with a reading accuracy of 0.1.
45° clickstop : Screw in the rotary knob (13.5) until
you feel slight resistance, then turn the stage to
the next noticeable clickstop. Loosen the rotary
knob, look for the position of the next clickstop
(e.g. extinction position of object) and retighten
the rotary knob. The stage can now be rotated at
clickstop intervals of 45°.
