Adjusting the rotating torque of the coarse focus knob

4.4
Adjust the rotation torque of the coarse focus knob
(rotation resistance) by turning the torque
adjustment ring (TORQUE) located at the base of
the coarse focus knob. If the torque is too low, the
stage may descend under its own weight.

How to Use the Coarse Focus Upper-limit Clamp

4.5
The coarse focus upper-limit clamp restricts the movement of the coarse focus knob to maintain
the stage at a position where the specimen is in focus. (The clamp does not restrict stage
motion adjustments made with the fine focus knob.)
When the coarse focus upper-limit clamp is engaged, the stage cannot be raised with the coarse
focus knob. Engaging the coarse focus upper-limit clamp after accurate focus has been achieved
lets you return to this precise focus position simply by turning the coarse focus knob until the
stage reaches the limit position set by the clamp. This function is intended to save time when
several similar specimens are observed in sequence.
[Directions of use]
(1) With a specimen in focus, rotate the coarse
focus upper-limit clamp about 3/4 turns in the
direction of the arrow on the microscope
base. This engages the coarse focus
upper-limit clamp.
(2) To change specimens, lower the stage using
only the coarse focus knob.
(3) After positioning a new specimen, use the
coarse focus knob and gently raise the stage
until the stage contacts the clamp. When the
stage contacts the clamp, the specimen
should be in focus. Use the fine focus knob for
precise focusing adjustments.
(4) When not using the coarse focus upper-limit
clamp, loosen the coarse focus upper-limit
clamp until it reaches the stopper. (Turn in
the direction opposite the direction of the
arrow indicated on the microscope base until
no farther rotation is possible.)
