WORLD PRECISION INSTRUMENTS 1
Introduction
WPI’s PZMIV stereomicroscope is an ideal tool for tissue dissection, cell injection,
specimen manipulation, electrode inspection and many other applications
requiring a magnified stereo view and ample working distance. It offers quality and
performance at an affordable price. Advanced optics provide image sharpness
found only among the best of this class.
PZMIV uses modular, parallel-beam path design and a high quality optical system.
The advanced optical design with plan achromatic objectives provides sharp and
distortion-free image throughout the entire zoom range. The ergonomic design
makes it easy to use — zooming is smooth and effortless, controlled by a large
spring-loaded knob.
With an extensive array of optional accessories, PZMIV is suitable for almost any
bio-research application requiring a stereomicroscope.

Operation
Refer to Figure 1 on page 3 and system diagram on page 4 along with the
following instructions on normal operation.
1. Set Up Microscope on Track Stand
Mount the microscope head into the focus mount. Use focusing knob to bring
microscope to focus.
2. Interpupilary Distance Adjustment
Looking through the eyepieces with both eyes, adjust the interpupillary
distance by sliding the two eyepiece tubes with both hands until a single
image is observed.
3. Focus Adjustment
Place a sample under the microscope, turn magnification knob (4) to its
greatest setting (5.0). Focus the image by turning the focusing knob (7).
Once image is in clear focus at its highest magnification you may zoom out
to lower magnification by adjusting magnification knob (4) while remaining in
focus.
4. Diopter Adjustment
If image does go out of focus when zooming out, zoom to the lowest setting
and focus each eyepiece individually by adjusting the diopter adjustment ring
(2).
5. Video/Photo Applications
Slide the light path selector bar (13) to the “PHOTO IN” position in order
to direct the light to the video/photo port (12). Remove the protective cap
on top of the video/photo port. Slip and secure the body of C-mount CCD
camera Coupler (11) over the video/photo port, with its focus ring facing
back. Attach C-mount video or digital camera (when using cameras with an
integrated lens filter thread of 28, 37 or 43 mm, Digital Camera Adapter Kit
#501384 is required). Refer to camera’s manual for connecting camera to
monitor. Focus image on screen by adjusting the fine focus ring located at the
back of the C-mount CCD camera coupler (11).

Maintenance
This instrument should be kept in a cool, dry place free from direct sun, dust, alkali
and acid fumes as well as moisture.
Do not disassemble any of the lenses since they have all been properly aligned
at the factory. The glass surfaces of the lenses should be cleaned with lens tissue
or brushed with a soft camel-hair brush. Any dust which has fallen on lens exterior
surfaces may be blown away with a commercial grade clean dust spray.
If stains deposit on exterior surfaces of the lenses, clean them gently using a mild
soap solution with a lint free cloth. Industrial solvents should not be used since they
may penetrate to the inside of the lens components and dissolve the lens cement.
When cleaning and lubricating the mechanical parts, special attention must be
taken not to stain the optical surfaces with grease. The moveable mechanical parts
should be lubricated occasionally with a non-corrosive grease.
When not in use, remove the eyepieces and put them back into the lens box.
Replace them with the eyepiece tube dust covers. The microscope should then be
secured in its box or covered with a dust cover.

Appendix: Boom Stand Assembly
1. Remove all parts from box
2. Unscrew hex screw from Vertical Post. Vertical post
should have cross block attached to it.
3. Screw Vertical Post and Base together using hex screw.
(Insert screw from bottom of base, into threaded section
of vertical post)
4. Insert Horizontal Bar into opening in cross block, slot side
facing up.
Two different types of focusing assemblies are available:
E-arm
1. Remove E-arm from protective packaging
2. Insert E-arm into the end of the Horizontal Bar, secure by
tightening set screw.
3. Tighten one or both hex screws (2.5 mm and 4 mm) so the microscope head is
tiltable but not free to swing.
Tips
E-arm can be inserted from the TOP, BOTTOM or END of the Horizontal Bar.
For oblique viewing, set E-arm up at various angles and then tighten handle.
