IV. OPERATION
1. Plug in the power plugs.
2. When you use the “BRESSER Science ETD-101” with trans-
mitted illumination, you should turn on the power switch (21)
at first, then turn on the transmitted light brightness adjusting
knob (17), which means the transmitted light working. Then
put the plastic object plate (16) on the base, and take down
the organic glass plate (16).
When you use it with incident illumination, you should plug
the incident illumination power plug (6) and turn on the
power switch (21) as well as the incident light brightness ad-
justing knob (14), which means the incident light working.
Then adjust the angle and brightness of the incident light il-
lumination to satisfy your needs.
When you use it with mixed illumination, you should turn on
both light brightness adjusting knobs and adjust their bright-
ness to obtain satisfactory mixed illumination.
3. If you want to change the position of observation, you can
loose the holding screw of tube (18). Then turn the binocu-
lar or trinocular head in any angle which you need, then
tighten the screw (18) again.
4. Turn both diopter rings (3) to "0" and the zoom knob (7) to
4.5x. Observe through the right tube with your right eye and
turn the focus adjustment knob (10) to make the image of
the specimen clear. Then observe through the left tube with
your left eye and adjust its diopter, not adjusting the focus
adjustment knob (10) again, to make the image of specimen
clear.
5. Turn the zoom knob (7) from 4.5x to 0.7x. If the image isn't
clear, you should observe through the left and the right eye-
piece tube with respective eye and adjust the respective di-
opter ring (3) to make the image clear. Then turn the
zoom knob (7) to 4.5x again. If the image isn't clear, you
should adjust the focus adjustment knob (10) to make the
image clear. According to the adjustment above, you can ob-
tain a clear and continuous image from 4.5x to 0.7x.
6. Observe the image with both eyes. Adjust the interpupillary
distance of the eyepiece tubes (4) until the both fields of view
can be superpositioned.
7. If you need an accessorial objective, you can turn it into the
objective hood (8).
8. If you need the annular illumination, you can connect it to
the objective hood (8) with a holding screw.
V. EXCHANGE OF THE LAMP
1. Turn off the power switch (21). Plug out the mains adaptor
(13) and the power supply plug (12).
2a. Incident illumination: Unplug the power supply plug (6).
Loosen off the lamp cover (19), pull out the bad lamp and
then install a new lamp. Tighten the lamp cover again and
plug in (6).
2b. Transmitted illumination: Remove the object plate (16) and
pull out the bad lamp. Then install a new lamp and mount
the plate again.
2c. Annular illumination: Loose the annular illumination holding
screw, take off the bad illumination and install a new.
Tighten the holding screw again.
VI. MAINTENANCE
1. Sweep the lens: Sweep the lens by lens tissue or soft fabric
immersed with alcohol (e.g. isopropanol).
2. Clean the painted parts: The dust on the painted parts can
be removed by gauze. For the grease spots, the gauze
immersed slightly with aviation gasoline is recommended. Do
not use organic solvents such as alcohol, ether or other
thinner etc. for cleaning the painted parts or plastic compo-
nents.
3. Avoid disassembling the microscope: Because of being a
precise instrument, do not disassemble the microscope ca-
sually. That may cause serious damage to its performance.
4. Being not used: Cover the microscope with the dust cover
(made of polymethylmethacrylate or polyethylene) and
place it there, where it is dry and mouldless. We suggest the
storage of all objectives and eyepieces in a closed
container with drying agent.
