SAFETY NOTES

1. Open the shipping carton carefully to prevent any accessory, i.e. auxiliary 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 envelope 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 stereomicroscope 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 the 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, 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 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.

Using the Black & White Stage Plate & Setting the Specimen (Fig. 2)
The White side of the stage plate is generally used when viewing specimens. If the specimen is white or bright in color, the Black side of the stage plate can be used to make the image appear clearer.
Set the glass stage plate ⑨ on the center of the base, and secure the slide with the two stage clips ⑩.
Using the Glass Stage Plate
For examination of specimens requiring transmitted illumination, use the frosted/glass stage plate.

Adjusting Binocular Viewing Head
Adjusting Interpupillary Distance (Fig. 3)
Different users have different interpupillary distances (this distance is between the centers of the pupils of each eye). When the operator changes, it will be necessary to adjust the interpupillary distance.
While looking through the eyepieces, hold the left and right eyetubes of the viewing head and adjust the eyetubes by opening or closing them until the left and right fields of view coincide completely and you are able to see a complete circle.

Adjusting Diopter Ring (Fig. 4)
Set the dioptor rings of both eyepieces to “0” position. (Do this when users change, because different users will have different diopter settings.)
Place an easy-to-observe specimen on the stage plate, i.e., a coin.
Rotate the zoom knob to the highest magnification, then turn the focusing knob to ocus the specimen.
Rotate the zoom knob to the lowest magnification, looking only into the left eyepiece, adjust the diopter ring on left eyepiece to focus he specimen. Then repeat procedure for the right eyepiece.

NOTE: The working distance (the distance between the microscope objective to the top of he specimen) of the microscope is 100mm, the binocular head focus mount can be mounted onto higher or lower positions according to your needs by removing the clamping bolt with the Allen wrench provided.
Focus Adjustment
Adjusting the Rotation Tension of the Focus Adjustment Knob (Fig. 5, Fig. 6)
To adjust tension, hold both left and right focus adjustment knobs ① with both hands, hold the left knob (to prevent it from turning), and rotate the right knob clockwise to increase (tighten) or counterclockwise to decrease (loosen) the focus knob tension.
After tension adjustment has been completed, always rotate both adjustment knobs in the same direction.

Changing the Magnification (Fig. 5)
The zooming knobs ③ located on both sides of the zooming body will change the magnification of the specimen image.
Total Magnification = Magnification of zoom body x magnification of eyepiece (i.e., 4.5 x 10=45x)
NOTE: If using any of the optional auxiliary objectives, then the above magnification would be multiplied by auxiliary objective magnification. (i.e., auxiliary 0.5 x 45=22.5x)
Moving the Microscope
Before moving the microscope, be sure to remove any slide/samples. When moving the microscope, hold the stand and base to keep it level.

Mounting & Removing the Reticle (Fig. 7)
Unscrew the mounting ring from the eyepiece. Clean the reticle and insert it into the mounting ring with the inscription side up. Screw the mounting ring back onto the eyepiece.
To remove the reticle, unscrew the mounting ring from the eyepiece, then carefully take out the reticle and wrap it in clean soft paper for storage. Screw the mounting ring back onto the eyepiece.

Using an Auxiliary Lens (Fig. 8)
The auxiliary lens can be threaded onto the bottom of the microscope body.
The 0.5x auxiliary lens can be used with most stands if purchased along with the extension tube.
The 0.3x and 0.4x auxiliary lenses can only be used with boom stands, ball bearing stands, or the flex arm stand. Trinocular Viewing Head
Mounting the Camera (Fig. 9)
The c-mount adapter is shipped assembled and separate from the microscope.
Mount the camera by screwing the threaded end 3 of the c-mount adapter into the camera first.
Insert the camera and adapter into the hole in the top of the viewing head and tighten the lock screw 2. Adjusting the Image (Fig. 10)
Turn the zoom knob to the maximum magnification, observe through the camera and adjust the focusing knob to make the image clear. Turn the zoom adjustment knob to the minimum magnification. If the image is not clear, turn the adjustment ring ① on the c-mount adapter until it is clear.
Repeat the process until the image is clear within the entire zoom range.
