2. Unpacking and assembly

The microscope is packed in a molded

styrofoam container.



Take the container out of the carton remove

the tape and carefully lift the top half off the

container. Be careful not to let the optical

items (objectives and eyepieces) drop down.



To avoid condensation on the optical com-

ponents, leave the microscope in the original

packing to allow it to adjust to room temper-

ature.



Using both hands (one around the pillar and

one around the base), lift the microscope

from the container and put it on a stable

desk.



The objectives will be found within individual

protective vials. Install the objectives into the

microscope nosepiece from the lowest mag-

nification to the highest, in a clockwise direc-

tion from the rear.



Insert the eyepiece into the tube and secure

it in place using the small hex key.



Secure the head with the large hex key.

3. Operation

3.1 General information



Set the microscope on a level table.



Place the object to be observed in the center

of the object plate.



Connect the mains cable to the net and turn

on the switch to get the object illuminated.



Make certain that the specimen is centered

over the opening in the stage.



Make the necessary eyepiece dioptre ad-

justments to suit your eyes (refer to 3.2).



Adjust the interpupillary distance so that one

circle of light can be seen (refer to 3.3).



Adjust the aperture of the iris diaphragm to

get the background brightness suitable for a

high contrast image.



Rotate the nosepiece until the objective with

the lowest magnification is pointed at the

specimen. There is a definite "click" when

each objective is lined up properly.

NOTE: It is best to begin with the lowest power

objective. This is important to reveal general

structural details with the largest field of view

first. Than you may increase the magnification

as needed to reveal small details.
