Installing a Mechanical Stage
The MI-4100STD model comes pre-drilled
for the addition of an optional mechanical stage
(our item MI-MESTAGE). This added feature
gives precise slide control for optimal viewing.
To install the mechanical stage follow these
steps:
1.
Remove the stage clips with a Phillips #2
screwdriver. The clips are screwed in tightly,
so be careful not to strip the screw heads.
2.
The mechanical stage attaches to the three
holes that are located between the stage
clips. The two pins on the bottom of the
mechanical stage fit into the smaller holes
on each side of the threaded hole in the
center. Align the pins with these holes and
seat the mechanical stage firmly against the
microscope stage.
3.
Secure the mechanical stage to the
microscope stage by tightening the center
set screw securely into the center (threaded)
hole.
Operating Procedure
Now that you have an overview of how to
use each component on your microscope, follow
this step-by-step procedure to help you get
started using it.
1.
Set the microscope on a tabletop or other
flat sturdy surface where you will have
plenty of room to work. Plug the power cord
into an outlet, making sure that the excess
cord is out of the way so no one can trip
over it or pull it off of the table.
2.
Flip the switch to turn on your microscope's
light source and then turn the disc
diaphragm to the largest hole (number 5),
which allows the greatest amount of light
through. On MI-4100DXL, open the iris
diaphragm to the fully open position.
3.
Rotate the nosepiece to the lowest-power
(4x) objective. You will hear a click when it is
properly in place. Always start with the
lowest power: it is easiest to scan a slide at
a low setting, as you have a larger field of
view.
4.
Turn the coarse focus knob to move the
stage down (away) from the objective lens
as far as possible.
5.
Set a microscope slide (coverslip facing up)
in place under the stage clips. A prepared
slide works best the first time. (If you do not
have a prepared slide, place a strand of
colored yarn or thread on a blank slide and
place a coverslip over it.) Move the slide
until the specimen is under the objective
lens.
6.
Adjust the larger coarse focus knob until the
specimen is in focus. Slowly move the slide
to center the specimen under the lens,
nudging it with your fingers if necessary.
7.
Adjust the small fine focus knob until the
specimen is clearly in focus. Then adjust the
diaphragm to get the best lighting. Start with
the most light and gradually decrease until
the specimen image has clear, sharp
contrast.
8.
Scan the slide (right to left and top to
bottom) at low power to get an overview of
the specimen (nudge the slide very slowly
with your fingers). Then center the part of
the specimen you want to view at higher
power.
9.
Rotate the nosepiece to the 10x for 100x
magnification. Refocus using the fine focus
knob and view your specimen carefully.
Adjust the diaphragm until the image has the
best contrast. Repeat with the 40x objective
for 400x magnification.
