three position sliding rod (b) allows user to easily direct microscope image into desired path.

1) Rod pushed completely into head; 100% of microscope image is directed to binocular
eyepieces.

2) Rod at mid-position (pull or push rod until you feel a gentle click stop), 100% of microscope
image is directed to trinocular port.

3) Rod pulled to fully extended position; 30% of image directed to binocular eyepieces, 70%
directed to trinocular port.

5

E. Eyepieces: Remove the dust caps from eyepiece tubes. Avoid touching any lens surface and Insert

eyepieces into the eyepiece tubes.

F. Filter: Swing out filter holder has built in frosted filter – must be in place when using the 4x and 10x

objectives.

OPERATION

G. Illumination.

1. Before operating microscope, adjust intensity control located on side of base to the minimum

H. Interpupillary adjustment of viewing head (Models 168 and 169 only)

I. Focusing the microscope.

position. This should be done prior to each time light is turned on or off. This will extend bulb life.

2. Insert power plug into 12VDC switching power converter, then insert plug on other end of converter into
power jack on back of microscope base. Note that the 12VDC converter will operate on either 120v or
240v current, 50 hertz or 60 hertz, eliminating the need for any other transformer.

3. Push rocker switch at rear of base to ON position.

4. Rotate intensity dial on illuminator base until image is illuminated.

5. Adjust intensity of light to match requirements of objective and specimen slide.

6. In case of equipment malfunction, see “Trouble Shooting” procedures.

1. Look through microscope and adjust distance between the two eyepiece tubes by grasping the sliding
mounts to left and right of eyepieces and sliding together or apart.

2. When a full field of view is observed through both tubes, and images blend into one, interpupillary
distance is corrected for your eyes. Check the interpupillary scale and note index reading for future
reference, in case other users will be changing this adjustment from time to time.

3. Adjust the diopter scales, located on each eyepiece tube, to the same numerical value as indicated on
the interpupillary scale. This must be done in order to maintain parfocality of objective lenses. If
interpupillary distance is changed, adjust eyepiece diopters accordingly.

1. Position the 4x objective lens into the optical path, making sure that lens is properly indexed in its click­stop position.

2. Place standard specimen slide (cover slip up) on top of stage surface.Swing moveable finger on slide
holder outward. Place specimen slide against fixed side of slide holder. Slowly release moveable finger
until it makes contact with specimen slide.

3. Rotate coarse focusing controls until specimen comes into focus.

6

4. Adjust fine focus controls until specimen is in sharp focus.

5. Adjust diopter for difference in eyesight.
a. Using right eye, peer into the right eyepiece tube. Adjust sharpness of image by utilizing fine focus

controls.

b. Using left eye, peer into the left eyepiece tube. Adjust sharpness of image by turning diopter

adjustment located on left eyepiece tube.

6. Adjusting the aperture (opening) of iris diaphragm.
Iris diaphragm should not be used to control the brightness of illumination, use light intensity control

knob to adjust light level. Iris diaphragms are designed to help achieve high resolution of specimen and
provide contrast in the image. Smaller apertures will deliver higher contrast to image. However, closing
aperture too much will reduce resolution. Experimentation is the best method of determining the correct
opening of diaphragm. Some suggested openings for iris diaphragm are:

OBJECTIVE DIAPHRAGM OPENING

4x 1/8 open (MIN)
10x 1/8 to 1/4 open
40x 1/4 to 1/2 open
100x 1/2 to 3/4 open (MAX)

7. Changing magnification.

a. Rotate revolving nosepiece to position 10x objective into optical path.
b. This microscope has been parfocalized, which allows changes from one objective to another while

requiring only a slight adjustment of the fine focus controls.

c. When changing to the 40x and 100x objective lens, care must be exercised in order to prevent

damaging the front lens element and specimen slide.

d. In order to obtain maximum resolution of the 100x oil immersion lens, it is necessary to apply

immersion oil between the coverglass of slide and front lens of the objective.

1) Use of a very small amount of immersion oil is required. Only the very tip of the lens

should ever come in contact with the immersion oil. Oil should not come in contact
with the white sealant ring on the objective. Excess use of immersion oil will ruin your
objective and void your warranty.

2) All air bubbles must be removed from between lens and slide by rotating nosepiece back and
forth.

8. When finished viewing, all parts that come in contact with oil must be cleaned. Failure to do so could
permanently damage the 100x oil immersion objective lens. Use of Windex to clean immersion oil off
lens surfaces is recommended.

9. Coarse focus tension adjustment.
a. Tension adjustment knob is located between stand and coarse focus knob of microscope, on the

right side.

b. To tighten tension of coarse focus knobs, turn control in a counter-clockwise direction. It is

advisable to leave controls as loose as possible, tightening only enough to keep stage from drifting
down and out of focus. To loosen tension, turn control in clockwise direction.

7

INSTALLING C-MOUNT CAMERA (to trinocular model only)

(b)

(c)

(a)

Trinocular model #169 is equipped with a port on top of head. Using the included C-Mount adapter and the
three-position sliding rod (c) allows use to easily direct microscope image into desired path.

1) Rod pushed completely into head; 100% of microscope image is directed to binocular eyepieces.

2) Rod at mid-position (pull or push rod until you feel a gentle click stop); 100% of microscope images is directed
to trinocular port.

3) Rod pulled to fully extended position; 30% of image is directed to binocular eyepieces, 70% directed to
trinocular port.

4) Remove front cap from the D-Moticam c-mount camera. Thread front of
camera onto threads of video adaptor (b).

Locate knurled screw located on side of trinocular port on microscope.
Turn screw counter-clockwise to permit removal of black plastic disk
covering trinocular port.

Insert video adaptor tube into trinocular port. If adaptor does not insert
easily, further loosen knurled screw at side of port until adaptor tube drops
into port and is firmly seated. Retighten knurled screw to secure adaptor
and camera in place. Pull sliding rod (c) until half way extended, to direct
100% microscope image to trinocular port. Proceed with operation of

digital camera and computer/monitor according to manufacturer’s

directions. With the live image on the monitor, slowly rotate the knurled
diopter on “C” adapter until image is in focus on monitor. If microscope
image does not remain in focus when microscope magnification is
changed, recheck digital c-mount camera chip size. Perhaps it will be

necessary to either replace or remove the top “CS” adaptor ring in order for

the video adaptor to be compatible with the chip size of your digital c-mount
camera.

MAINTENANCE
WARNING: FOR YOUR SAFETY, TURN SWITCH OFF AND REMOVE PLUG FROM POWER SOURCE

OUTLET BEFORE MAINTAINING YOUR MICROSCOPE. TO AVOID SHOCK OR FIRE HAZARD, IF
POWER CORD IS WORN, CUT OR DAMAGED IN ANY WAY, HAVE IT REPLACED AT ONCE.

A. OPTICAL MAINTENANCE

1. Do not attempt to disassemble any lens component. Consult an expert technical service company when
repairs not covered by these instructions are required.

2. Prior to cleaning any lens surface, brush dust or dirt off lens surfaces using a camel hair brush. Or use
air to blow dust and lint off surfaces. Use of compressed air in a can, available at any computer supply
store, is a good source of clean air.

3. Cleaning eyepiece lenses. Do not remove eyepiece from eyepiece tube. Clean only the outer surface.
Breathe on lens to dampen surface, then wipe with lens paper. Do not wipe lens surface while dry as
lenses are scratched very easily. Wipe a circular motion from center to outer edges.

4. Cleaning objective lenses. Do not remove objective lenses from microscope. Clean front lens element
only. Using a cotton swab saturated with distilled water, clean front lens surface. Inspect the lens using
a magnifying glass to insure that the element is clean. If immersion oil or specimen material of any kind
is evident, use a cotton swab dipped in a small amount of Windex to clean all foreign material from
objective lens surface. Such material will reduce, or totally block, image quality.

5. Cleaning condenser lens. Clean only the top lens surface, visible when looking through hole in top of
stage. Use same procedure as used for eyepiece or objective lenses.

6. Illuminator condenser lens. Use same procedure as used for eyepiece or objective lenses.

CALIBRATION

– (*Optional – not necessary to use your microscope*)

To prepare for the calibration process, please make sure you have the calibration slide. The calibration slide
has four individual dark round circles. Each dark round circle corresponds with each objective on your
microscope.

 The 1.5mm dot (150um – microns) with the 4X objective.
 The 0.6mm (600um – microns) with the 10X objective.
 The 0.15mm (150um – microns) with the 40x objective.
 The 0.07mm (70um – microns) with the 100X objective.

To begin the calibration process, place the calibration on the stage.

1. First place your calibration slide on the stage, switch to the 4X objective, and move the slide over to the

1.5mm dot.

2. With the dot centered on the tablet screen, select the calibration button, located on the bottom right hand

side of the screen. Select Calibrate the Image.

3. Make the captured image is clean and round. Then click the Calibration button again.

4. You should have a bright green circle on the screen.

5. This time the calibration settings window will open.

6. In the objective magnification window select the objective you captured the dot with. In this case the 4X

objective.

7. In the diameter window select the diameter of the dot you captured. In this case the 150um. Then click

OK.

8. The last window that will open is the Save Calibration window. Since you capture this image with the 4X

objective, it is best to enter this on this line.

9. The objective line should default to the objective you are calibrating. In this case it should say 4X.

10. The X and Y numbers on the next two lines should be near identical. Look at the first three numbers. As

long as they are the same within one or two digits, you have a good calibration.

Click Ok and you are done.

TRANSFERING IMAGES TO YOUR COMPUTER

By default all your images are saved to the Micro SD card included with your M10T-BTW series microscope.
This card is provided as a courtesy. If it is missing or lost, you will need to purchase a replacement. It is highly

CLEANING YOUR MICROSCOPE

Dirty

Clean

National microscopes are designed to function with minimal maintenance, but certain components should be
cleaned frequently to ensure ease of viewing. The power switch should be turned off or the microscope should
be unplugged when not in use.

Do not disassemble your microscope

Disassembly may significantly affect the performance of the instrument, and may result in electric shock or
injury and will void the terms of the warranty.
Never attempt to dismantle any parts other than the ones described below. If you notice any malfunction,
contact your nearest National Optical supplier.

Optics
Keeping the optics of your microscope clean is essential for obtaining clear images.
Choosing the best cleaning method depends on the nature of the optical surface and type of dirt.

Dirtiness on the image may be caused by the following
variables:

 Dirt on the outer or inner eyepiece lens.
 Dirt on the front lens of the objective.
 Dirt on the upper lens of the condenser.
 Dirt on the surface of the sample slide glass.
 Dirt on the upper lens of illuminator.
 Dirt on other optical components of the microscope such

as mirrors, lamps, filters, intermediate lenses …

In the case of microscopes with a camera attached to it:

 Dirt on the camera adapter.
 Dirt on the protection filter of the camera sensor.

For Eyepieces with reticules:
 Dirt on the outer or inner reticle glass.

Objectives are the optical component of the microscope that
require the most maintenance. Because for their actual use,
they can get dirty easily.

For objectives that work without oil (dry): The first step is to carefully unscrew the objective from the nosepiece.
In order to make things easier and safer, screw the objective onto one of the objective cases supplied with

microscope. By doing it this way, the objective will be in a stable position avoiding possible falls.
(1) Proceed by cleaning it using pressurized dry air - or an air gun if available – and, if after this is done we still

observe spots of dust or dirt, (2) Clean with a cotton swab dampened with a low graduation of alcohol 70% or
with a mixture of alcohol and ether (ratio alcohol: 3 to ether: 7). (3) With a spiral movement (starting from the
center of the lens) we will then clean the surface of the lens. (4) Dry its surface by using pressurized dry air
and check that the lens is clean either with the help of a magnifying glass or by screwing the lens back on the
revolving nosepiece of the microscope.

37

For objectives that work with immersion oil it is essential to clean them after each observation session. To
clean use a cleaning cloth for lenses slightly dampened with a low graduation of alcohol. Proceed by cleaning
the frontal objective lens (normally 100X-Oil). It is important for those objectives that work at a very close
distance to the sample.

For optical components such as eyepieces, condensers, filters, etc. we recommend using the same
cleaning method. First cleaning it with pressurized dry air, then cleaning it with a cotton swab or a cleaning
cloth for lenses (slightly moistened with a low graduation of alcohol) and finally drying it with pressurized dry air.
Once the cleaning process is finalized if the image is still not clear, you can either contact us or you can contact
your National Optical supplier.

For users that have a digital camera mounted on the microscope and whom observe dirt on the digital
image, it is important that the first step is to proceed with objectives maintenance, as explained above. If the
dirt persist, it must be determined if it is within the microscope or the camera. To check this simply loosen the
adapter and rotate the camera. If the dirt rotates while turning it, then it means that it is in the microscope. If it
does not rotate, then it is either in the adapter or in the protection filter of the sensor. If the dirt is on the surface
lens of the adapter then you can use the same cleaning method that we have explained above, but if the dirt is
in the protection filter of the sensor then use pressurized dry air only. If the dirt persist you can either contact us
or you can contact your National Optical supplier.

Mechanics
The mechanical components of the microscope require less maintenance than the optical components. Our
first maintenance advice is to use the dust cover provided with the microscope, to avoid the accumulation of
dust on the microscope.

To clean the stand or the specimen holder, Use a cleaning cloth moistened with soap diluted in distilled
water. After this proceed drying the entire surface of the microscope. Take special care with the electrical
components of the microscope such as the ON / OFF switch, the dimmer, the lamp holder…
If there are grease stains, use the same cloth moistened with a low graduation of alcohol.

If you face any problems related to the maintenance of your microscope, please contact us. Our technicians
will gladly help you solve your maintenance issue/s.

CLEANING – The front lens of the objectives (particularly the 100XRD) should be cleaned after use. The lens
surface may be gently cleaned with a soft camel hair brush, or blown off with clean, oil-free air to remove dust
particles. Then wipe gently with a soft lens tissue, moistened with optical cleaner (eyeglass or camera lens) or
clean water. Immediately dry with a clean lens paper.

CAUTION - Objectives should never be disassembled by the user. If repairs or internal cleaning should be
necessary, this should only be done by qualified, authorized microscope technician. The eyepiece(s) may be
cleaned in the same manner as the objectives, except in most cases optical cleaner will not be required. In
most instances breathing on the eyepiece to moisten the lens and wiping dry with a clean lens tissue is
sufficient to clean the surface. Lenses should never be wiped while dry as this will scratch or otherwise mar the
surface of the glass.

The finish of the microscope is hard epoxy and is resistant to acids and reagents. Clean this surface with a
damp cloth and mild detergent.

Periodically, the microscope should be disassembled, cleaned and lubricated. This should only be done by a
qualified, authorized microscope technician.

DUST COVER AND STORAGE – All microscopes should be protected from dust by a dust cover when in
storage or not in use. A dust cover is the most cost-effective microscope insurance you can buy. Ensure that
the storage space is tall enough to allow the microscope to be placed into the cabinet or onto a shelf without
making undue contact with the eyepieces. Never store microscopes in cabinets containing chemicals which
may corrode your microscope. Also, be sure that the objectives are placed in the lowest possible position and
the rotating head is turned inward and not protruding from the base. Microscopes with mechanical stages
should be adjusted toward the center of the stage to prevent the moveable arms of the mechanical stage from
being damaged during storage in the cabinet.
