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 shipping carton; the container should be retained should the microscope
ever require 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. All electrical connectors (power cord) should be inserted into an electrical surge suppressor to
prevent damage due to voltage fluctuations.
6. 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.
7. Confirm that the input voltage indicated on your microscope corresponds to your line voltage. The
use of a different input voltage other than indicated will cause severe damage to the microscope.
IMPORTANT NOTICE TO PREVENT
DAMAGE TO THE STAGE
To prevent damage to the mechanical stage during transit, the mechanical stage
is locked into place by a metal plate and two screws.
PRIOR TO OPERATION of the microscope, the metal plate and both screws MUST be removed.
An Allen wrench is included in the shipping carton to use for removing the screws.
Failure to remove the metal plate and two screws prior to operation
will cause severe damage to your mechanical stage.
See diagram on next page.

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 such as
cotton swabs or Q-tips, 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 preventative
maintenance to maintain proper performance and to compensate for normal wear. An annual
schedule of preventative maintenance by qualified personnel is highly recommended. Your
authorized ACCU-SCOPE® distributor can arrange for this service.

INTRODUCTION
Congratulations on the purchase of your new ACCU-SCOPE® microscope. ACCU-SCOPE®
microscopes are engineered and manufactured to the highest quality standards. Your microscope will
last a lifetime if used and maintained properly. ACCU-SCOPE® microscopes are carefully assembled,
inspected and tested by our staff of trained technicians in our New York facility. Careful quality control
procedures ensure each microscope is of the highest quality prior to shipment.
UNPACKING AND COMPONENTS
Your microscope arrived packed in a molded shipping carton. Do not discard the carton: the carton
should be retained for reshipment of your microscope if needed. Avoid placing the microscope in dusty
surroundings or in high temperature or humid areas as mold and mildew will form. Carefully remove the
microscope from the Styrofoam container by its arm and base and place the microscope on a flat,
vibration-free surface. Check the components against the following standard configuration list:
1. Stand, which includes the supporting arm, focusing mechanism, mechanical stage, slide holder,
nosepiece, N.A. 1.25 Abbe condenser with iris diaphragm and illumination system.
2. Viewing head (binocular or trinocular depending upon the model ordered)
3. Eyepieces as ordered
4. Objectives as ordered
5. Immersion oil
6. Dust cover
7. 3-prong electric power cord
Optional accessories such as optional objectives and/or eyepieces, slides sets, etc., are not shipped as
part of the standard equipment. These items, if ordered, are shipped separately.

ASSEMBLY
Objectives
The objectives have been pre-installed on the microscope. Always rotate the nosepiece by using the
knurled nosepiece ring.
Viewing Head
Remove the protective plastic disk from the head and neck. Loosen the viewing head clamp screw
slightly and set the head onto the microscope arm. Tighten the thumb screw to lock the head in the
desired position. Ensure the viewing head is firmly secured by the dovetail and thumb screw before
releasing your hold.
Eyepieces
Remove the eyetube plugs and insert the eyepieces into the eyepiece tubes. Lock in the eyepieces using
the supplied Allen wrench to tighten the Allen screw on each eyetube.
Mechanical Stage
The mechanical stage is held in place by a metal retainer. Remove the two screws holding the retainer
using the supplied Allen wrench.
Condenser
The condenser was installed and centered by our technicians prior to delivery. If the condenser needs to
be re-installed or adjusted in the future, please follow the following procedure: from below, mount the
condenser on the condenser holder with the aperture control lever facing forward. Tighten the two
centering screws until the condenser is in the center of the field of view when the diaphragm is closed.

ASSEMBLY (continued)
Filter
If desired, a blue filter may be installed onto the bottom of the condenser. NOTE: When installing the
filter, hold it from the edges as you do not want to leave fingerprints on the filter. Remove the filter holder
from the bottom of the condenser and insert the filter into the filter holder Insert the filter holder back into
the bottom of the condenser.
Voltage Check
Confirm that the input voltage indicated on the rear label of the microscope corresponds to your line
voltage. The use of a different input voltage than indicated will cause severe damage to your
microscope.
OPERATION
Plug the 3-prong line cord into the microscope and then into a grounded 120V or 220V A.C. electrical
outlet. Usage of a surge suppressor outlet is highly recommended. Turn the illuminator switch to “―.”
For longer bulb life always turn the illuminator variable intensity knob to the lowest illumination intensity
setting possible before turning the power on or off.
Binocular or Trinocular Viewing Head
To adjust the interpupillary distance, hold the left and right eyetubes while observing a specimen. Rotate
the eyetubes around the central axis until the fields of view of both eyetubes coincide completely. A
complete circle should be seen in the viewing field when viewing the specimen slide. An improper
adjustment will cause operator fatigue and will disrupt the objective parfocality.

OPERATION (continued)
Illumination
The light level may need adjustment depending upon the specimen density and objective magnification.
Adjust the light intensity for comfortable viewing. The illumination level may vary when changing from
one objective to another. To eliminate irregular light when using low power objectives (4X, 10X) raise or
lower the condenser using the condenser adjustment knob. The iris diaphragm should be slightly
opened or closed to obtain optimal contrast of the specimen being observed. Adjust the iris diaphragm
to the smallest size allowable for a clear, sharp image of the specimen. The setting for the iris
diaphragm will vary depending on the specimen being viewed.
Focusing
To ensure that you obtain sharp images with both eyes, (since eyes vary, especially for those wearing
glasses) any eyesight variation can be corrected in the following manner. Set both diopter collars to “0”.
Using your left eye only and the 10X objective, focus your specimen by adjusting the coarse adjustment
knob. When the image is in view, refine the image to its sharpest focus by turning the fine adjustment
knob. Rotate the diopter collar to obtain the sharpest focus. To obtain the same sharp image using your
right eye, do not touch the coarse or fine adjustments. Instead, rotate the right diopter collar until the
sharpest image appears. Repeat several times to check. NOTE: do not counter rotate the focusing
knobs as this will cause severe problems and damage to the focusing system.
Adjustable Tension Control
Located on the left side of the stand between the coarse adjustment knob and the vertical arm is an
adjustable tension control dial that is preset at our facility. This allows the user to adjust the coarse
control tension to their individual preference.
