*Please read these instructions
carefully before use.
.
1. OPERATION
(1.) As the microscope is a precision instrument, always handle
it with care, avoiding impact or abrupt movement during
transportation.
2. MAINTENANCE
(1.) All glass surfaces must always be kept clean. Fine dust on
the optical surface should be blown off by means of a hand
blower or gently wiped off with a soft lens tissue. Carefully
wipe off oil or fingerprints on the lens surfaces with tissue
moistened with a small amount of 3:7 mixture of alcohol
and ether.
(2.) Do not use organic solution to wipe the surface of the other
components. These parts, especially the plastic parts,
should be cleaned with a neutral detergent.
(3.) Do not take down or assemble it yourself.
(4.) After use, cover the microscope with the dustcover provided,
and keep it in a dry and clean place for preventing rust.
(2.) Do not let the microscope be in sunlight directly. Keep
it in a dry and clean place. Avoid high temperature and acute
shaking. Following environment is required: Indoor
temperature: 0°C~40°C, Max relative humidity: 85%.
(3.) Avoiding impact the definition of the image, do not leave
feculence and fingerprints on the lens surfaces.
(4.) Before using, examine to ensure the power supply voltage
is consistent with the rating voltage.

3. PARAMETER/TECHNICAL TERMS
4-5 TECHNICAL TERMS
(1) Total magnification=(magnification of objective) X (magnification
of eyepiece)
(2) Field of view=(line field of view of the eyepiece selected)
÷(magnification of the objective selected)
(3) N.A.=n·sinα (max), N.A.is very important parameter which
marks the features of the objective and condenser. The “n”
is the refractive index of the medium (air or immersion oil)
between the cover glass of the objective and the specimen.
The “α” is the half of the aperture angle. The N.A.is bigger,
the resolution of the objective is higher.
(4) Object to primary image distance: the distance between the
object plane to the primary image plane. The conjugate
distance is fixed.
(5) Mechanical tube length: The distance between the objective
shoulder and the ocular shoulder.
