Start-Up and Operation
3.4
Unplug the plug-in power unit from
line power before converting the
microscope.
3.4.1
• Loosen clamp screw (Fig. 11/2), turn the
installed
approximately 90° (Fig. 11/A) and on the right
side take it of upward (Fig. 11/B).
For reasons of space, the tube may
also be clamped by the grub screw
with hexagonal socket head supplied
with the tube.
• Insert the tube to be installed, with the
eyepieces pointing to the right and its dovetail
mount slightly inclined, under the two holding
elements (Fig. 11/4) in the stand.
• Then, place the tube horizontally onto the
stand. In doing so, the groove on the underside
of the tube must be located above the third
holding element (Fig. 11/3) of the stand.
• Turn
the
(eyepieces pointing frontward), align it to the
stand and tighten clamp screw (Fig. 11/2).
For
microscope (e.g. in a cabinet) the tube
may also be rotated by 180° to the
back.
3.4.2
• Move the condenser carrier fully up by turning
the knurled screw for vertical adjustment
(Fig. 4/15).
• Unscrew the cover cap (Fig. 12/3) from the
luminous-field diaphragm (Fig. 12/1).
• Put the desired filter – yellow, green or blue –
(Fig. 12/2) onto the mounting surface of the
luminous-field diaphragm and screw the cover
cap back into place.
