Installation
4.2 Instrument installation
a.
Take off the microscope from the carton box and remove all protections. Hold the
microscope with both hands from the stand to avoid damaging any component and
place it carefully on a stable flat surface.
b.
Remove all plastic and paper protections from each part of the microscope (eyepieces,
light, diaphragm,…)
c.
Place the head in its position and fix it with the lateral screw.
d.
Familiarize with the mechanical components of the microscope. Move these
components to see how they behave and if they operate properly.
e.
Insert the plug into the socket at the back of the microscope. Connect the other end to
the electrical power supply. If the batteries are charged the microscope can be used
without connecting to the electrical power supply.
Note:
in case of using the microscope connected to the power supply, it should be properly
earthed. Make sure the input voltage is the appropriate for this equipment (100-240V; 50-
60Hz).
4.2 Using the instrument
a.
Turn the power source of the microscope on by pressing the switch at the back of the
microscope. The light intensity can be regulated by means of the knob placed at the
left side of the base of the microscope. It is recommended to be used at 70% of
intensity.
b.
Place the simple (microscope slide) and hold it with the clamp; to open the clamp use
the metal lever at the left side.
c.
The amplitude of the light beam that reaches the simple can be adjusted by changing
the diaphragm aperture. The maximum resolution is obtained by adjusting properly
this aperture. Every time the objective is changed and to get the best resolution it is
