Assembly
All the steps described for the assembly of the stereomicroscope must be undertaken with extreme
care, and without forcing the placement of the distinct parts and elements of the stereomicroscope.
A. Place the base of the microscope (13) upright on a flat,
stable and clean surface.
B. Ensure that the head holder locking screw (Fig. 1) is
tight.
C. Loosen the head holder locking screw (5) and place
head (14) in head holder (17) with extreme care.
D. Tighten screw.
E. Connect incident illumination to power cord (15) located
at the upper part of the column (21).
WARNING: Before connecting the stereomicroscope to a
power source, always check that the voltage coincides
with that of the stereo microscope.
Operation
A. Starting Up
The stereomicroscope has two stages. One is frosted glass and is used for the observation of
microscope slides or samples that are thin or transparent, such as leaves, insect wings, etc. The
black and white stage is used for non transparent objects, or for dissection. For best contrast,
choose the side of the stage to use.
Warning
: Transmitted illumination can ONLY be used with the frosted glass stage. THE HEAT
GENERATED BY THE TRANSMITTED ILLUMINATION CAN MELT OR DAMAGE THE BLACK
AND WHITE STAGE. SUCH DAMAGE WOULD NOT BE INCLUDED UNDER WARRANTEE.
1. Changing the stage.
a. Loosen the stage plate locking screw (12) and remove the stage (11).
b. If wishing to use the glass stage, insert the blue filter in the centre of the base with
the frosted surface facing down.
c. Place the glass stage with the frosted surface, again, facing down.
d. Retighten the stage plate locking screw.
2. Before connecting the stereomicroscope to a power source, adjust light intensity to its
minimum (24). This must be repeated every time the stereomicroscope is turned on or off, to
prolong the life of the bulb.
Three light switches are located on the base of the microscope.
MAIN : The principal switch, which turns the whole unit on or off.
I
: Turns incident light on or off. (Illumination from above)
T
: Turns transmitted illumination on or off (illumination from below)
