4.2.1 Pupil distance adjustment
The pupil distance (eye distance) varies from person to person, so before using this instrument,
the pupil distance of the binocular should be readjusted.
A) transfer the eyepiece on the left and right sides to the 0 pairs of lines according to (Figure 06).
B) 10X objective is screwed into the light path, moving specimens to the light path, observing the
eyepiece, adjusting the coarse and find hand wheel to make the image clear.
C) hold the binocular left mirror tube and the right mirror tube respectively, and rotate it according to
(Fig.7) until the specimen is seen by both eyes. Complete coincidence (the process of A to B and then
to C)
4.3.1Visual adjustment
A) transfer the left eyepiece tube and right eyepiece tube to the 0 pairs of lines according to (Figure 06).
move the specimen to the light path.
B) Turn 40 X objective to light path. The right eyepiece is used to observe the specimen in the right
eyesight. Adjust the coarse and find focusing hand wheel to make the specimen clearly visible.
C) Observing the specimen on the left eyepiece. If the imaging is not clear, it is necessary to adjust
the eyepiece's visibility, so that a clear specimen image can be observed in left eye (adjust diopter ring,
the range is: N= + 5 diopter ).
4.4.1 Focus and stopper
A) Loosen the limit handle shown in Figure 07 and turn it into the 10X objective into the light path, and
slowly turn the coarse moving handwheel unit the image is clear in the eyepiece.Roughly clear, then
slowly rotate the micro motion handwheel to make the imaging clear. Turn to other times objective, it
should be properly rotate the hand wheel to make the image clear. The minimum scale handwheel is
0.002mm.

B) For convenience observation and avoid objective to touch with the slider, use stopper when focusing
well (figure 07).
