Preparations For Observation
1
Adjust the torque of the focus knob.
Adjust the torque of the focus knob so as not to fall down the zooming
body on its own weight.
[C-FMC]
Turn the torque adjustment ring using the
clamp tool. Turning the ring in the direction
of the arrow indicated on the side surface of
the focusing mount will increase the torque.
Note) • Do not twist the left and right focus
knobs.
• Do not turn the knob beyond its
turning limit.
• Do not turn the fine focus knob while
holding the coarse focus knob or vice
versa. Otherwise, the damage to the
instrument will result.
[C-PS and C-PSC]
Rotating the left and right focus knobs in the
opposite direction as shown in the illustration
will increase the torque.
2
Adjust the interpupillary distance.
This adjustment should be performed every
time the observer is changed since the
interpupillary distance differs between
individuals. Adjust the interpupillary distance
so that the view field for each eye is merged
into one. Move while holding each sleeve
with both hands.
Increasing the torque.
(To reduce the torque,
turn the knob in the direction
opposite to the arrow.)
