OPERATING INSTRUCTIONS
Follow these simple instructions to begin using your zoom stereo microscope:
• Your stereomicroscope should always be used on a hard, flat and stable surface.
• Plug the stereomicroscope power cord into a grounded electrical outlet. A grounded 3-wire line cord is
provided.
• Select the appropriate light switch for the specimen. There are three types of illumination:
Incident Light (top) – to view opaque specimens.
Transmitted Light (bottom) – to observe translucent specimens.
Incident & Transmitted – to develop contrasting conditions on any variety of specimens.
• 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.
• Focus the stereomicroscope at the highest power by turning the zoom control knob to 4.5x and then use the
large focusing knob(s) to bring the specimen into focus. Rotate the zoom control knob to the lower powers,
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 knobs may be needed to sharpen
the focus.
TENSION ADJUSTMENT OF FOCUSING KNOBS
Turn one focusing knob with other focusing knob held tight by your opposite hand. This will increase or decrease
the rotation tension, depending on which direction the knobs are turned. This adjustment is intended to prevent the
microscope body from drifting, which will occur if the knobs are loosened too much.
CLEANING THE OPTICS
Do not attempt to disassemble the inclined binocular or trinocular body or focusing mechanisms. These have been
aligned and scales for protection against dust, dirt, or other particles by our factory technicians. Only exposed
surfaces should require cleaning. To clean the zoom stereo microscope:
• Blow dust particles from the lens surface with an ear syringe.
• 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.
LAMP REPLACEMENT
If replacement is necessary follow these simple instructions:
DANGER!!!
Do not attempt to change the lamp before allowing it to completely cool.
TRANSMITTED (BOTTOM) ILLUMINATION
• Unplug the electrical cord.
• Carefully lay the instrument on its back and unscrew the base assembly.
• Remove the old lamp, and insert the new lamp being careful to avoid leaving fingerprints on the lamp
surface. The bulb number to reorder is # 3368
• Reattach the base assembly. Do not operate the microscope unless the base is securely attached.
