Z850 STEREO MICROSCOPE
Adjusting Interpupillary Distance (Fig. 6)
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. 7)
Set the dioptor rings ② 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 ③ to the highest
magnification 5x, then turn the focusing knob ④
to focus the specimen.
Rotate the zoom knob ③ to the lowest
magnification 0.8x, looking only into the left
eyepiece, adjust the diopter ring on left eyepiece
to focus the specimen. Then repeat procedure
for the right eyepiece.
NOTE: The working distance (the distance
between the microscope objective to the top of
the specimen) of the microscope is 115mm, the
binocular head bracket ⑤ can be mounted onto
higher or lower positions according to your
needs by removing the clamping bolt with the
Allen wrench provided.
