Safety Precautions
1. Avoid placing the microscope in places exposed to direct sunlight, high temperature or humidity, dusty, and
subject to strong vibrations, and ensure that the worktable is flat, level and strong enough. (Weight: about 29.5 kg
for the main unit).
2. If it is necessary to move the microscope, hold the transport handle tightly and keep the microscope and the
work surface with a gap before moving the microscope (above).
3. If bacterial solution or water splashes on the stage, objective lens or observation tube, unplug the power cord
immediately and wipe off the spilled liquid or water. Otherwise, the instrument may be damaged.
4.
When working, the lamp house will become very hot. Make sure there is enough space for heat
dissipation around the lamp house, otherwise heat will accumulate and the instrument will be damaged.
5. Before turning on power to the lamp house, make sure that the correct power source is connected. Before
replacing the bulb or fuse, switch off the power supply. Wait for the lamp chamber to cool down completely before
proceeding.

Ⅴ. Microscope observation
1. Objective lens
1. When the objective lens changer is rotated to change the objective lens, turn to positioning and hear a
"click" sound to ensure that the required objective lens enters the center of the optical path.
2. During operation, first use a low-magnification objective lens (4X or 10X) to search and focus the sample,
and then switch to a high-magnification objective lens for observation as needed.
3. If the objective lens is replaced, it can also be installed through the opening on the stage.
Note that the magnification of the objective lens is consistent with the scale on the converter. Generally,
turn the objective lens converter clockwise, and the order of magnification is from low to high.
2. Trinocular tube
(1) Adjust the viewing angle
First observe one side eyepiece with one eye and rotate the
coarse focus handwheel and the fine focus handwheel to focus
the sample. Then look with the other eye. Check the other side
of the eyepiece, if the image is not clear, you can use the
eyepiece diopter adjustment ring to focus on the sample so that
both eyes can see the specimen clearly at the same time.
★There are ± 5 diopters on the eyepiece diopter adjustment ring, which is the same as that on the eyepiece tube.
The value of the dot alignment is the diopter value of the eye.

(2) Adjust the interpupillary distance
The binocular hinges are rotated toward or away from each other to adjust the interpupillary distance of the
eyepiece, and the left and right visual fields are two as one. The height of the exit pupil can also be adjusted.
Interpupillary distance adjustment range: 55 ~ 75mm
The indication point "·" on the eyepiece seat corresponds to the scale on the interpupillary distance indicator, and
the size of the interpupillary distance at this time can be read.
