5. THE FIRST OBSERVATION - IN BRIEF
HOW TO PROCEED:
I. Sit down comfortably and, preferably, place the microscope in front of you on a table
(e.g.
a desk or dining table)
.
II. Connect the mains adapter or insert the batteries.
III. Set the POWER switch to the 'I' position.
IV. Place your fi rst test object on the round glass plate
(the microscope’s 'stage')
. This could be
a leaf, an insect, fi bres, a prepared slide or any other item you may choose.
V. Move the rotary lighting switch from the 'OFF' position to 'I', 'II' or 'III', as desired.
VI. Using both eyes, look through the eyepieces and move them either together or further
apart to suit your particular eye separation.
The image fi eld should appear relatively round and should not be darker on one side
than on the other one.
VII. Use the focusing wheel to fi nd optimum sharpness.
VIII. If one eye is weaker than the other, then accomodate this by adjusting the 'dioptre' eye-
piece on the left-hand side while simultaneously looking through both eyepieces.
IX. Have a good look at the object.
X. If necessary, adjust the brightness for optimum illumination.
XI. Turn the objective lens unit to 4X. You now have 40-fold magnifi cation and will see that
the object appears much larger.
