P.6
is soft in light to suit the operator for a long time micro-observation. When the current and
voltage don't overstep their limits, its average life can reach to 100000 hours. It is very
securely because the bulb's temperature is lower than 30°C even in a long time using.
Equiped with rechargeable and high-capacity NiMH batteries, it can avoid the trouble of
power supply shortage.
The position of the bulb in microscope is very import to the imaging quility. When the
lighting centre is not coaxial with the objective, there will be large different in the eyepiece
veiwing field: one side may be dark and another side may be bright. The bulb has been
placed correctly in our factory. When change the bulb, please keep it centring.
Caution:
----Before change a bulb, ensure that the microscope has been disconnected with
the power source.
----The new bulb must be the same specifications as the old one.
----When the illuminator is halogen lamp or incandescent lamp, the base near the
lighting source may be very hot. Don't worry about it, but it must be treated
carefully. Please take the combustible material(such as gasoline, paper, plastic and
cloth) far away from the microscope.
----When change incandescent bulb or halogen bulb, wait until it is cool enough,
otherwise the hot bulb will burn your fingers
.
----Don't leave any dust and fingerprints on the bulb, otherwise it may affect its life
and illuminating efficiency.
Lay the microscope on its side, Loose the screw(16) under the bottom, open the bulb
case(19) to change the bulb.
D) How to use and assemble:
1. Unpack the microscope and its parts carefully. Check and sort out all parts according
to the packing list;
2. For the convenience of packaging and delivering, the components and parts may be
separated from the mainframe. Before using, please assemble them together according to
the structure draft(Fig 2).
1) Install the viewing head:
The viewing head of model XSP21-01M, or XSP21-01S, or XSP21-01V is fixed on the
mainframe. But the binocular head of model XSP21-01B and the trinocular head of model
XSP21-01T are usually separated from the mainframes. Loose the screw(27) and take off
the plastic plate cover on the body(22). Take the plastic plate cover on the viewing head.
Finally install the viewing head on the body(22) and fix it with the screw(27). Don't try to
loose another two screws for centring the viewing head on the body(22).
2) Install the objectives(4):
Usually, the objectives are fixed stably on the nosepiece by us. Sometimes, they are
separated from the mainframe. Screw the plastic dust cover out off the nospiece(1) and
take the objectives out off their plastic bottles. Screw them on the nospiece(1) by their
maganification order from low to high.
3)Install the eyepiece(3):
Take off the plastic dust cover from the eyepiece tube and insert the eyepiece needed.
3. The operating steps:
1) Select a position to work where little direct light falls on the instrument. Keep the
microscope far away from a large window and not to face the window, because the direct
light may adversely affect the contrast and resolution of the image.
The following working surroundings are required:
a) Room temperature: 0°C-40°C The highest relative humidity: 85%
b) High temperature and humidity can cause mildew and damage the instrument.
