SAFETY NOTES
1. Open the shipping carton carefully to prevent any accessory, i.e. objectives or eyepieces, from
dropping and being damaged.
2. Do not discard the molded Styrofoam container; the container should be retained should the
microscope ever requires reshipment.
3. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty environments.
Ensure the microscope is located on a smooth, level and firm surface.
4. If any specimen solutions or other liquids splash onto the stage, objective or any other component,
disconnect the power cord immediately and wipe up the spillage. Otherwise, the instrument may
be damaged.
5. CAUTION: the lamp, lamp housing and adjacent parts will become very hot. Do not touch these
parts until they have completely cooled. Never attempt to handle a hot halogen bulb.
6. All electrical connectors (power cord) should be inserted into an electrical surge suppressor to
prevent damage due to voltage fluctuations.
7. For safety when replacing the halogen lamp or fuse, be sure the main switch is off (“O”), remove
the power cord, and replace the halogen bulb after the bulb and the lamp house has completely
cooled.
8. Confirm that the input voltage indicated on your microscope corresponds to your line voltage. The
use of a different input voltage than indicated will cause severe damage to the microscope.

CARE AND MAINTENANCE
1.
Do not attempt to disassemble any component including eyepieces, objectives or focusing
assembly.
2.
Keep the instrument clean; remove dirt and debris regularly. Accumulated dirt on metal surfaces
should be cleaned with a damp cloth. More persistent dirt should be removed using a mild soap
solution. Do not use organic solvents for cleansing.
3.
The outer surface of the optics should be inspected and cleaned periodically using an air stream
from an air bulb. If dirt remains on the optical surface, use a soft cloth or cotton swab dampened
with a lens cleaning solution (available at camera stores). All optical lenses should be swabbed
using a circular motion. A small amount of absorbent cotton wound on the end of a tapered stick
makes a useful tool for cleaning recessed optical surfaces.
Avoid using an excessive amount of
solvents as this may cause problems with optical coatings or cemented optics or the flowing
solvent may pick up grease making cleaning more difficult. Oil immersion objectives should be
cleaned immediately after use by removing the oil with lens tissue or a clean, soft cloth.
4.
Store the instrument in a cool, dry environment. Cover the microscope with the dust cover when
not in use.
5.
ACCU-SCOPE microscopes are precision instruments which require periodic servicing to
maintain proper performance and to compensate for normal wear. A regular schedule of
preventative maintenance by qualified personnel is highly recommended. Your authorized
ACCU-SCOPE distributor can arrange for this service.

Placement of Slide Specimen (Figure 22)
1.
Place the slide on the mechanical stage. Use the slide
holder to gently secure the slide.
2.
Rotate the X and Y adjustment knobs of the mechanical
stage to position the specimen for viewing.
Figure 21
 Use caution when changing objectives. Do not allow an
objective to touch a specimen slide.
Focusing (Figure 23)
1. With the 10x objective in position, raise the mechanical stage
using the coarse focusing knob until the specimen is close
to the objective.
Figure 22
2. Rotate the coarse focus knob① until the specimen is in
focus. Then use the fine focus knob② to obtain a sharp image.
You may now switch to another magnification objective.
 To prevent your specimen slide from making contact with
an objective, raise the stage to its highest position
without contacting the 100x objective, then tighten the
upper limit mechanical stage lever.

Adjusting the Condenser (Figure 24)
Turn the condenser focus knob to raise or lower the condenser.
The condenser is raised when using high magnification objectives
and lowered when using the low magnification objectives.
Figure 24
 The centering of the condenser and the light axes of the
objective are factory adjusted. Do not attempt
re-adjustment.
 The highest position of the condenser has been factory
adjusted. Do not attempt re-adjustment.
Adjusting the Iris Diaphragm (Figure 25)
Move the Iris Diaphragm Lever① left or right to adjust the
aperture size.
The iris diaphragm is designed to adjust the aperture size,
not to adjust brightness.
Generally, reducing the diaphragm opening to 70- 80%
of the N.A. value of the respective objective will provide
an image of acceptable quality. If you want to observe
the image of the iris diaphragm, remove one eyepiece
and look through the tube. You will see a dark circle
encroaching on the bottom of the tube.
Figure 25
Adjusting the Interpupillary Distance (Figure 26)
The interpupillary distance range: 55mm~75mm.
While observing with both eyes, hold the left and right
prism eye tubes. Rotate the eye tubes around the central
axis. The interpupillary distance is correct when the left
and right fields of view coincide completely with one
image.
Figure 26

Adjusting the Eyepiece Diopter (Figure 27)
1.
Using the 10x objective and your right eye only, observe your
specimen through the right eyepiece and bring it into focus,
2.
Then observe the specimen with your left eye only through the
left eyepiece. If the specimen is not in focus, rotate the diopter
ring① until a sharp image is obtained.
The diopter adjustment collar is on the left eyetube.
Figure 27
The right eyepiece tube is fixed. Do not attempt to rotate
the right eyetube.
★ The diopter range is ±5
Adjusting the Tension Adjustment Collar (Figure 28)
The tightness of the tension adjustment collar has been pre-set at
the factory. If the mechanical stage drops by itself, rotate the
tension adjustment collar① until the tension is in maintained.
Figure 28
Rotate the collar in the direction show in the picture. The
Coarse Focus Knob② will become tighter.
