Remove the battery compartment cover by
pressing lightly on the cover clip. Insert the
batteries into the holder.
Important! Pay attention to the polarity as
marked on the battery holder terminals.
As your device has continuously controllable
lighting (dimmer) optimal illumination of the
object to be viewed is guaranteed.
3. Colour filter disc
The colour filter under the microscope
table (Fig. 1, 19) aids in viewing very bright
and transparent objects. Just select the
right colour for the specimen in question.
The components of colourless/transparent
objects (e.g. starch particles, single-cell
-specimens) can thus be better recognised.
4. Interchangeable illumination lenses
The illumination of your microscope contains
two lenses (Fig. 2, 16+17). These are –
according to the object being viewed – to be
attached to the LED illumination for best results.
The ground glass lens Fig. 1, 16) is already
mounted on the lighting unit. To change the
lenses, simply screw them on and off. Just turn
the upper lighting unit (Fig. 1, 10).
An overview of purposes:
Matted lens (Fig. 2, 16) to be used for
• views with the PC eyepiece (Fig. 2, 4)
• viewing of extremely small items with
eyepiece (Fig. 2, 1+2) and Barlow lens
(Fig. 2, 3)
Condenser lens (Fig. 6, 17) to be used for
• viewing of standard items with eyepieces
(Fig. 2, 1+2) and Barlow lens (Fig. 2, 3)
5. Attach mechanical desk
A mechanical desk is included along with
your microscope (located in the case, under
the CD). To install this on the microscope,
proceed as follows:
1. Place the mechanical desk (Fig. 4, 28) on
the microscope stage (Fig. 4, 8) in such a
way that the attachment screws (Fig. 4, D)
are positioned over the middle threaded hole
(Fig. 4, E).
2. Tighten the attachment screws securely.
6. Microscope setup
The microscope's eyepiece
6) will now be prepared for the first
observation.
First, loosen the screw (Fig. 1, X27) and rotate
the eyepiece into a convenient position.
Begin every observation with the lowest
magnification.
Place the microscope's table (Fig. 1, 8) with the
focus knob (Fig 1, 9) into the lowest position
and rotate the objective revolver (Fig. 1, 7) until
it locks on the lowest magnification (4x).
nOTe:
First, drive the Microscope's
table (Fig. 1, 8) to its lowest
position before changing the
objective in order to prevent
damage.
Insert the 5x eyepiece (Fig. 3, 1) in the Barlow
lens (Fig. 3, 3).
Take care, that the Barlow lens is inserted
completely in the monocular head (Fig. 3, 5).
7. Observation
After you have set up the microscope with
the corresponding illumination, the following
principles are important:
Begin each observation with a simple
observation at lowest magnification, so that
the centre and position of the object to be
viewed is in focus.
(Fig 1,
The higher the magnification the more light is
required for good picture quality.
Place a permanent slide culture (Fig. 5, 15)
directly under the microscope lens on the plate
(Fig. 5, 8) and clamp it on the cross-table (Fig.
5, 28). To do so push the lever (Fig. 5, C) aside.
The specimen to be examined must be directly
over the lighting. If not turn the two knurled
screws (Fig. 5, A+B) on the mechanical plate.
