checking the entire list, please contact Olympus.
Problem Cause Remedy Page
1. The left and right fields of view do
not coincide.
Interpupillary distance is adjusted
improperly. Adjust it correctly.
The parallax is not corrected. Adjust it correctly.
The left and right eyepieces are
different. Use eyepieces with the same magni-
fications for the left and right by re-
placing one of them.
2. The edge of the field of view is ob-
scured or not evenly illuminated.
The aperture iris diaphragm is stopped
down (when the SZX-AS is used). Open the aperture iris diaphragm.
The binocular tube and/or intermedi-
ate attachment are installed improp-
erly. Install them properly.
The light path selector knob is in an
intermediate position. (SZX-TR30) Set it properly.
3. Dirt or dust is visible in the field of
view.
Dirt/dust on specimen. Clean thoroughly.
Dirt/dust on eyepieces
4. Details of observed image are
solid.
The aperture iris diaphragm is stopped
down (when the SZX-AS is used). Open the aperture iris diaphragm.
5. Visibility of observed image is poor.
· Image is not sharp.
· Contrast is poor.
The objective is tilted.
The objective is dirty. Clean thoroughly.
The top and/or bottom lenses of the
microscope body are dirty.
The bottom lens of the observation
tube is dirty.
6. Zooming causes defocusing of the
observed image.
The eyepiece diopter is adjusted
improperly. Adjust it correctly.
The focus adjustment is inaccurate. Adjust the focus accurately.
7. The focus adjustment knob does
not rotate smoothly.
The rotation tension of the knob is set
too high. Decrease the rotation tension to an
optimum level.
8. The microscope body drops spon-
taneously, causing the focusing to
be deviated during observation.
The rotation tension of the knob is set
too low. Increase the rotation tension to an
optimum level.
