First, make sure the area is
clean and dust free. Then, remove the eyepiece from the
eyetube.
Flip the eyepiece upside
down and locate the mounting ring that will be removed.
The ring may appear a different color of metal as shown
in the photo.
On the ring, there will be
two notches that are opposite each other.
You will need a tool like
a jewelers screwdriver that will fit well into the slot
and not damage the ring or eyepiece body.
The reticle retaining ring screws
into the eyepiece with a fine pitch thread.
With your tool, unscrew the
ring by rotating it counter-clockwise or to the left as
shown in the photo.
Be careful not to scratch
any of the surfaces inside your eyepiece.
Also be careful not to introduce
dirt or dust into your eyepiece during this procedure,
Next, carefully remove the ring
from the eyepiece.
Resist the temptation of
using your can of compressed air.
Oftentimes the mist that
comes from cans of compressed air leaves a white film
that is VERY hard to remove.
A very small paint brush
or a small very fine dusting brush used in cosmetics is
a good choice.
Next, you are ready to drop
in your eyepiece micrometer.
If you can tell which side
of the glass has the image etched on it, that side faces
into the microscope.
If you cannot, the markings
on your reticle may be out of focus which means the reticle
is installed backwards. You will need to remove the reticle
and flip it around the opposite way.
With the reticle in place, it's
time to return the threaded ring.
Again be careful not to introduce
dirt or dust into your eyepiece.You may need to clean
and start over again if too much debris is present.
Rotate the ring in a clockwise
motion until the ring is snug with the reticle.
Do not overtighten.
Check if the reticle is tight
by shaking the eyepiece and detecting no rattle.
With your reticle installed,
it's time to check your work.
Put the eyepiece to your
eye and point it to a light source overhead.
You should see the pattern
clearly.
If not, slide the eyepiece
into the microscope and make a basic setup.
If the reticle is still out
of focus, you may have the reticle installed backwards.
If flipping the reticle does not work, contact
Meiji or your local dealer for assistance.
