(I) TROUBLE SHOOTING
Stage drops out of focus
If you notice that when you focus on a specimen the stage drops out of focus the tension on the stage must be adjusted. To fix
look on the coarse focus arm on the left side of the microscope there are 4 little holes. Take the wrench that is supplied and
attach it to any to of the holes. Then give a quarter turn clock-wise. Tighten only enough to keep stage from drifting down and out
of focus.
Coarse focus is very hard to turn
If the coarse focus is very hard to turn, take the wrench that is supplied and attach it to the tension adjustment holes behind the
focus knob and turn until the tension for focusing is how you like it.
Objectives
If you are using any type of liquid on the slides and then view through the microscope, make sure that you clean the objectives
immediately after you are done. You can clean with paper towel and xylene. If you do not clean after contact with liquid th e
objective lens ill become very dirty and hinder the viewing quality of the objective.
The Eyepiece
If view is hindered check for fingerprints on the eyepiece or eyepiece lens could be scratched. Do not scratch eyepiece with your
fingernail, as this will remove the optic coating. Only clean outer lens do not attempt to take eyepiece apart. Clean by using a can
of compressed air for dust or breath on lens and wipe with lens paper.
Rack Stop Screw
In the microscope illustration, you see a stage rack stop screw. This screw sets how far up the stage will move. Students have a
tenancy to screw this all the way down. This limits the upper movement of the stage and objects will not come into focus. Simply
turn the screw back up, the more the screw comes up the higher the stage will come up. Do not turn the screw to far up because
the stage may hit the 40x and 100x objectives.
Slide and Cover Slip
If the slide does not come into focus check to see that the slide is not upside down. Make sure the cover slide is facing up .
Also make sure the slide is not dirty, spots will show up if it is. Also make sure that the cover slip over the specimen is not too
thick, use a 0.17mm thick cover slip over your specimen.
