6)
Maximize the field diaphragm by manipulating the field diaphragm adjust lever
on the Epi-fluorescence device.
7)
Focusing by rotating the coarse and fine focusing knobs to make the image
clear.
8)
To observe with other magnification objectives after getting ideal image.
9)
Centering the filament image of the high pressure mercury lamp.
Indistinct bright block of mercury lamp filament image can be seen in the view
field after getting the clear fluorescence image, pulling the light condenser to
move the light condenser axially to move the bright block in the brightest
position. If the bright block diverges the view field center, it can be centered by
adjusting the horizontal or vertical lever on the mercury lamp house (the
instrument has been adjusted before dispatching, in normal case, it would be
better not to center again).
10)
When use multigroup light source , can choose just compare with module
conversion position witch in front of the fluorescence device .
11)
Rechargeable Lithium power source specially for LED illumination can be used
above 10 hours continuously without external power supply. When it is
charging, the indicator is dark as the battery capacity lower than 80%, and the
indicator is flashing as the the battery capacity is 80%. The indicator is bright
as the battery capacity is full. The indicator comes dark after the external
power supply cut.
▲
Before perform fluorescence observation, locate the specimen with the
transmission light first.
▲
To prevent the fluorescence from attenuation quickly, block the excitation light
with barrier when preparing for fluorescence observation or photography. Only
when observing or photographing, irradiate the specimen with the excitation
light.
▲
Don’t switch off the mercury lamp within the initial 15 minutes it lights on for
avoiding shorten its lifetime. The user can block the light with the barrier when
leaving for a short time, and the lamp once turned off should be lighted on
again after 3 minutes.
▲
Fluorescence microphotograph requires a long exposure time, so it is better to
use the high sensitivity film (e.g.27 DIN).
▲
If Mercury lamp with strong light source
,
should in half light position of light
shutter in case of sample cancellation.
▲
Ordinary LED Power Box and Lithium power source without start button.
