4. USAGE OF MICROSCOPE COMPONENTS
4.1 Coarse and fine focusing (Fig.7)
Focusing is carried out with the coarse and fine focus knobs at the left and right of the microscope
stand.
The direction of vertical movement of the stage corresponds to the turning direction of the focus
knobs.
One rotation of the fine focus knob moves the stage 0.2mm. The graduation on the fine focus knob
is 2 microns.
Never attempt either of the following actions, since doing so will damage the
focusing mechanism:
Rotate the left and right knob while holding the other.
Turning the coarse and fine focus knobs further than their limit.

To increase the torque, turn the torque adjustment ring located behind the left-hand coarse focus
knob in the direction indicated by the arrow. To reduce the torque, turn the ring in the direction
