Focus On The Specimen - Nikon Multizoom AZ100 Instruction Manual

Focus on the Specimen

Caution
To avoid malfunctions, do not rotate the right and left focus knobs and the right and left stage
height adjustment knobs in an opposite direction. Additionally, do not rotate those knobs
excessively. Do not rotate the fine focus knob with holding the coarse focus knob nor vice
versa.
On this product, two types of height adjustment can be
performed: the stage height adjustment and the zoom body
height adjustment. Use any appropriate knob for your
convenient.
Zoom body height adjustment
The focus knobs are located on the both sides of the stand
elevating section. These knobs are used to adjust the height of
the zoom body to focus on the specimen. The coarse focus
knob and fine focus knob are provided for this purpose. One
revolution of the coarse focus knob allows the stage to move
by 18.5 mm and that of the fine focus knob allows by 3.27 mm.
Torque of the focus knob
The torque adjustment ring is located inside the left focus
knob. Insert the hexagonal screwdriver into the hole on the ring
and adjust the torque enough to prevent the zoom body from
descending with its own weight.
The torque is increased by rotating the torque adjustment ring
upward and decreased by rotating the ring downward.
Stage height adjustment
The stage height adjustment knobs are located on the both
sides of the stand elevating section. The coarse focus knob
and fine focus knob are provided. One revolution of the coarse
focus knob allows the stage to move by 37.7 mm and that of
the fine focus knob allows by 0.27 mm.
The center of the elevating range (reference position) is
marked on the right elevating section of the stage. When the
mark is located at the height of the microscope base part, the
stage is located at the center of the elevating range. (Refer to
the right figure.)
Torque of the stage height adjustment knobs
The torque adjustment ring is located on the left stage height
adjustment knob. The torque required to rotate the knob can
be adjusted by rotating this ring.
The torque is increased by rotating the torque adjustment ring
in the direction of arrow. Adjust the torque enough to prevent
the zoom body from descending with its own weight.
