FIRST TIME USE
Before installing and using the biological microscope, make sure to read carefully the Safety
Instructions.
1. When unpacking and handling, please do not touch the optical surfaces. After unpacking,
place the biological microscope on a flat workbench and remove any foam padding or spacer
used to prevent vibration during transportation.
2. Connect the cable/ charger to the power supply. Before plugging in, keep in mind that the
working voltage of the biological microscope shall be the same as the supply voltage.
3. Turn on the power switch at the back of the arm.
Note: Make sure that the brightness control is in the minimum position before turning on or
off the power switch.
4. Rotate the brightness control to the desired illumination.
5. After use, turn the brightness control to the minimum position, and then turn off the power
and put on the dustproof cover.
6. The coarse focus tension has been set at the factory, but can be readjusted as required.
OPERATION OF THE BIOLOGICAL MICROSCOPE
Interpupillary distance adjustment
1. While looking through the microscope, grasp the eyetubes and move them on their hinges
until the two circular fields in the observation field coincide with each other.
2. If several people will be using the same microscope, each user can record the correct
interpupillary distance for them from the scale. The microscope can then be quickly reset to
the correct distance.
Setting bright field illumination
The SILVER150 Series biological microscope has been set already before delivery and can
be adjusted as follows:
1.
Put the specimen on the stage and fix it with the slide clips.
Note: The thickness of the cover slip should be 0.17 mm.
2.
Open the condenser aperture diaphragm to the position matching the numerical aperture
of the objective.
3.
Lower or raise the condenser to locate the best illumination for the field.
4.
Rotate the brightness control to the desired intensity.
