8.8 Orienting the specimen
(only with orienting specimen clamp
fixture)
The specimen orientation allows a simple correction
of the position of the specimen surface while the speci-
men remains fixed in the specimen clamp.
Use the coarse feed buttons to move the specimen
to the rear limit (HOME) position..
Release the clamping lever on the right side of the
microtome base plate and approach the knife holder
base with the knife holder closely to the specimen.
Never attempt to orient the specimen while
the instrument is in the retraction phase (i.e.
while the yellow RETRACT indication is illu-
minated)! Prior to the next section, the speci-
men will advance by the retraction value plus
the selected section thickness! There is dan-
ger that specimen and knife will be damaged.
Rotate the handwheel to position the specimen
clamping system at the top of the cutting stroke and
activate the handwheel locking system.
To release the clamping mechanism rotate the ec-
centric bolt
(4)
counterclockwise.
Rotate adjusting screw
(5)
to orient the specimen
in north-south direction. Use adjusting screw
(6)
to
orient it in east-west direction.
To clamp the specimen in the selected orientation,
turn eccentric bolt
(4)
clockwise.
When using the large version of the standard
specimen clamp (50 x 55 mm) the specimen
orientation of 8° in north-south direction can-
not be used fully.
The north-south orientation angle is limited
to about 4°.
