1)
Use of the focusing text rod (M)
Fig.19
The rod is supplied as one of
standard accessories for confirming
the
microscope’s
accurate
adjustment. Insert it into the main
shaft hole with the flat surface facing
the objective lens the direction of the
operator (Fig.19).
Attention:
After
adjusting,
remember to take out the rod.
2) Brightness adjustment
Switch on the main power switch
and set the brightness control switch
(7) at ‘N’ position. Turn the slit
width control knob (35) to make the
slit width to be 2~3mm.
3) Diopter compensation
The focus of the microscope is
calibrated
according
to
the
emmetropia. If the operator is an
ametropia, he should adjust the
eyepiece diopter. One eyepiece
with four short reticle lines witch is
usually placed at the right side
helps to focus accurately after
accessories being attached.
Fig.20
Suggest adjusting the diopter as
following procedures
First,
rotate
the
diopter
adjustment ring (19) counter
clockwise down to the end.
(Fig.20).
Second,
rotate
the
ring
clockwise until a sharp slit
image
appears
on
the
focusing text rod.. At this
time, it is also the clearest
observation of the reticule in
the eyepiece
Adjust another eyepiece in
the same procedure.
Record the diopter value on
each eyepiece for future
reference.
4)
Interpupillary
distance
adjustment
Separate the prism box of the
microscope with both hands
to adjust the P.D. until both
eyes could see the same
image on the focusing test
rod through the eyepieces,
and at the same time a
stereovision will be obtained.
