Before use N2 SERIES
1、Operation
(1) As the microscope is a precision instrument, always handle
it with care, avoiding impact or abrupt movement during
transportation.
(2) Do not let the microscope emerge in the sun directly. Keep
it in a dry and clean place. Avoid high temperature and
acute shake. Following environment is required: Indoor
temperature: 0℃～40℃, Max relative humidity: 85%.
(3) Avoiding impact the definition of the image, do not leave
feculence or fingerprints on the lens surfaces.
(4) Before using, examine to ensure the power supply voltage
is consistent with the rating voltage.
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.
1. Nomenclature N2 SERIES
2.Operation N2 SERIES
The microscope is housed in a molded styrofoam container.
First take the container out of the carton, and lay the container
on its side. Open the container carefully and don’t let the
optical items drop down, avoiding them being damaged.
Check carefully to ensure the arm and accessories are well.
Second put the monocular head or binocular head onto the top
of the arm, and tighten the head-lock-screw. Install the
objective into the microscope nosepiece from the lowest
magnification to the highest, in a clockwise direction from
the rear. Insert the eyepiece into the eyepiece tube.
2-1 Angle of observation
Loosen the head-lock-screw and turn the monocular head or
binocular head to a comfortable position for observation.
Then lock the head-lock-screw.
2-2 Set the specimen slide
Place a specimen to be studied on a glass slide, and fix it by
the slide-holders of the mechanical stage. Turn the stage
knob to make certain that the specimen is centered over the
stage opening.
2-3 Set illumination
For the microscope only with mirror, turn the mirror to get
the field of view illuminated.
For the microscope with built-in electrical illuminator, insert
the plug of the main cable into the power socket and turn on
the power switch to get the specimen illuminated. Then turn
the brightness-adjustment-
knob slowly to get the brightness suitable.
2-4 Adjust focus
Loosen the limit-stop-knob, and adjust the coarse-focusing-
knob to bring the slide into focus. Then lock the limit-stop-
knob to avoid impact between the objective and slide. Adjust
the fine focusing knob
2.Operation N2 SERIES
to get the image clear.
For binocular head microscope, we also should do some
more adjustments:
(1)Hold the two ends of the head-cover and adjust the
interpupillary distance by pushing or pulling the cover, until
one circle of light can be seen.
(2)After finishing the interpupillary adjustment, look at the
graduation value in the middle of the head-cover. Turn the
two diopter-ring and aim the same graduation value at the
graduation line on the eyetube.
Avoiding decline of the stage, rotate the tension knob in a
clockwise direction to give a suitable force to the stage. If
we need to reduce the tension, rotate the tension knob in an
anti-clockwise direction.
2-5 Adjust diopter of binocular head
If the diopter of the two eyes is not same, binocular head
microscope has compensating function.
Turn the nosepiece to choose the objective 4X, and use the
left eye to observe the left eyepiece. Adjust fine-focusing-
knob and focus correctly. Use right eye to observe the right
eyepiece. Gain the clear image by turning the diopter-ring
up and down.
2-6 Adjust condenser
Turn the condenser-adjustment-knob to make the condenser
move up or down to concentrate light and to get the image
brightness suitable for observation.
2-7 Adjust diaphragm
Adjust the aperture of the iris diaphragm to get the
background brightness suitable.
2-8 Choose the objective
Turn the nosepiece to choose the objective. The objective
selected should be set vertically right to the slide. Generally,
first use the
2.Operation N2 SERIES
objective 4X to focus to reveal general structural image.
Then use the higher power objective to reveal smaller
details.
When using the oil objective 100XR, a little of immersion
oil must be put between the objective and the cover glass.
2-9 Change the lamp or put on the mirror
Before changing the lamp, first pull the plug out off the
electrical socket and wait for a while until the lamp cools
down to avoid being burnt. Loosen the door-screw on the
bottom to open the small door. Then you can see the lamp
and lamp holder. Pull the lamp out and insert a new one into
the holder. Close the door by tightening the screw.
While changing the mirror, screw off the base-lens or mirror
and screw on a new mirror.
