SAFETY NOTES
1. Open the shipping carton carefully to prevent any accessory, i.e., objectives or eyepieces, from dropping
and being damaged.
2. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty environments.
3. 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.
4. LAMP REPLACEMENT -- CAUTION: the glass housing of the lamp may be extremely hot.
DO NOT attempt to change the lamp before it is completely cooled or without wearing
adequate skin protection.
5. All electrical connectors (power cord) should be inserted into an electrical surge protector to prevent
damage due to voltage fluctuations.
6. FUSE REPLACEMENT -- For safety when replacing the fuse (ONLY replace with the same
size, type and rating of original fuse), be sure the main switch is in the off position, disconnect
the power cord from outlet, and replace the fuse. Reconnect the power cord and turn unit on.
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.
NOTE: Always plug the microscope power cord into a suitable grounded electrical outlet.
A grounded 3-wire cord is provided.
CARE AND MAINTENANCE
1. Do not attempt to disassemble any component including eyepieces, objectives or the 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 bulb. If dirt
remains on the optical surface, use a soft, lint free 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.
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.

IMPORTANT FEATURES
ACCU-SCOPE’s stereo microscopes have fixed magnification systems. Total magnification power is the
product of objective magnification multiplied by the eyepiece magnification:
Catalog # Eyepieces x Objective = Total Magnification
3052 10x 1x/3x 10x/30x
Inclined eyepiece tubes allow for interpupillary distance of 55mm to 75mm and diopter adjustment of ±5.
Working distance is 57mm. ACCU-SCOPE’s stereo microscopes feature a two-way illumination system which
may be used to provide transmitted light or reflected light. Your Stereo microscope comes completely
assembled and ready for use. Simply follow the step-by step operating procedure outlined in section 5.0 for
years of use from your stereo microscope.
MAGNIFICATION SYSTEM
Each microscope in the 3052-LED stereo microscope series has two objectives. The rotatable turret housing
the two objectives allows the user to easily change magnifications while the specimen remains in focus.
Additional magnification ranges can be obtained through the use of different eyepieces. Information, product
availability and pricing information is available from your authorized ACCU-SCOPE distributor.
ILLUMINATION SYSTEM
The 3052-LED Stereo microscope series is equipped with a built-in, two-way illuminator system. The
convenient on/off switch is located on the base of the instrument and controls both the incident and
transmitted illumination. The illumination system consists of a LED illumination from above and below.
OPERATING INSTRUCTIONS
Follow these simple instructions to begin using your stereo microscope:
1. Your stereo microscope should always be used on a hard, flat and stable surface.
2. Plug the stereo microscope power cord into a grounded electrical outlet. A grounded 3-wire line cord is
provided.
3. Select the appropriate light switch for the specimen. There are two types of illumination:
-Incident Light (top) - to view opaque specimens.
-Transmitted Light (bottom) - to observe translucent specimens.
4. Place a specimen on the stage plate area directly below the center of the stereo microscope body. While
looking through the eyepieces with both eyes, slowly adjust the distance between the eyepiece tubes until
you see a complete circle of light at the same time without moving your head. The eyepiece tubes are
inclined at 45 degrees to maximize your viewing comfort.
5. Focus the stereo microscope at the highest power by turning the objective turret to the highest
magnification power and then use the large focusing knob to bring the specimen into focus. Rotate the
turret to the lower power, making focal corrections by rotating the diopter collar off of the zero setting for
proper focus. This will keep the specimen in close focus at any magnification. A slight turn of the focus
knob may be needed to sharpen the focus.

CLEANING THE OPTICS
Do not attempt to disassemble the inclined binocular body or focusing mechanisms. These have been aligned
and sealed for protection against dust, dirt, or other particles by our factory technicians. Only exposed
surfaces should require cleaning. To clean the Stereo microscope:
1. Blow dust particles from the lens surface with an ear syringe.
2. Using a lens cleaning solution (available from most camera stores) moisten a cotton swab, cover
the swab with lens paper and carefully clean the lenses and eyepieces. This method may also be
used to remove oily smears and fingerprints, which detract from the image quality. Glass surfaces
should be cleaned very carefully and only when necessary. Use a circular motion when cleaning
glass surfaces.
