Upper Limit Bolt
3
The upper limit bolt is used to prevent the specimen touching the objective when a 40x or
larger-power objective (objectives with a small working distance) is used. Using the upper limit
bolt, the stage does not move up from a certain position. Attach the bolt as follows.
(1) Bring an objective with 40x or larger power
into the optical path. Focus on the specimen.
(2) Lower the stage to slightly below the position
set in step (1).
(3) Remove the field lens unit.
(4) A hexagonal socket head bolt is located in the
left hole at the lower part of the focusing
mechanism. Remove the bolt using a supplied
hexagonal wrench and screw it into the right
hole.
Note:
The upper limit bolt may not work well
depending on the thickness of the specimen
or the microscope itself. The specimen may
touch the 40x objective or the stage may
be stopped by the limit before the specimen
image is in focus. Check that the bolt works
before relying on it.
Cord Hangers
4
Push the cord hangers (optional) into the holes on
the rear of the microscope. The hangers can be
used for winding the power cord around when the
microscope is not in use. To remove the hangers,
use a screwdriver.
