Using the microscope

Unpacking and getting started

•

Unpack the microscope.

•

Make sure all the parts are present.

•

Move the stage to the lowermost position using the focusing knob.

•

Press the ON/OFF button located on the back side of the microscope base next to the power cord to turn

the microscope on.

Focusing

•

Place an object on the stage and x it with the slide holders.

•

Rotating the revolving head, switch magnication to the 4x objective.

•

Move the object to x its thickest part exactly under the objective.

•

Rotate the focusing knob to raise the stage until the objective is close to the specimen; keep checking

the distance between the objective and the object to avoid their contact.

•

Look through the eyepiece installed in the monocular head and lower the stage slowly rotating the

focusing knob until you see the object image.

Such adjustment protects the frontal lens from contacting the object when you use objectives of other

magnications; though, slight refocusing might be required.

Selecting the objective

We recommend that you start your observations with the lowest power objective; it helps to select a seg-

ment for the detailed research. Once the segment is selected, you should center its image in the micro-

scope’s eld of view. This operation should be performed as precisely as possible, otherwise the required

segment might fail to appear in the eld of view of the higher power objectives.
