Before Use D1 series
1. Notice
⑴As the microscope is a precision instrument, a always
operate it with care, avoiding physical shake during the
operation.
⑵Do not let the microscope emerge in the sun directly, either
not in the high temperature, damp, dusty or acute shake
place. Make sure the worktable is horizontal.
⑶When moving the microscope, you should use both hands to
hold ①and ②as shown on figure, and lay it down
carefully. (Figure 1)
★If hold the focusing knob, eyepiece tube or stage
during moving, you will damage it.
⑷During working, the light condenser will become hot.
Please make sure enough space around ③for
cooling.(Figure 2)
⑸Connect the microscope to earth avoid lightning
strike.
⑹Make sure the power switch ④is on “0” (off) before
replacing the bulb or fuse and wait until the lamp
cools down. (Figure 3
★Bulb: 6V/20W halogen bulb（Philips 7388）
⑺It can adapt wide voltage 90~240V. There is no need
for transformer. Make sure the voltage is in this
range.
⑻Use the special plug supplied by our company.

2．Maintenance
⑴Wipe the lens gently with a soft lens tissue. Carefully wipe off oil or fingerprints on the lens surfaces with
tissue moistened with a little of 3:7 mixture of alcohol and ether or dimethy lbenzene.
★Alcohol and ether is flammable. Don’t place these chemical near to fire or fire source. For example,
when turning on or turning off the electric device, you should use these chemical in a ventilated place.
⑵Don’t use organic solution to wipe the surfaces of the other components. Please use the neutral detergent.
⑶If the microscope damped by the liquid, you should cut off the power immediately and wipe it dry.
⑷Never disassemble or service the microscope yourself. It will influence its function or damage it.
⑸After using, cover the microscope with a dust cover.

If the coarse adjustment is too tight or uncomfortable
or image swiftly out of focal plane after focusing or
the stage sleeks down, please use knob  to adjust.
(Figure 13)
Turn the knob  with the direction showed to tight
the knob. And opposite direction for loosement.
3-5 Adjust diopter （Figure 14&15）
1. Turn one dioptor ring  to make it in line with
reticle  on eyepiece tube. At this time, the

(Suitable for sliding head)
Or
Turn one dioptor ring  to make “0”position in line
with reticle  and make the image clear. Then
observe through another eyepiece. If the image is
blur, please adjust another diopter till the image
clear. (Figure 15)
 Diopter is ±5 and when it is in line with reticle

3-6 Adjust interpupillary distance
Slide the board  with direction showed to make
image through both eyepieces syncretic. (Figure
16)
The interpupillary distance: 52-75mm
 Please remember own interpupillary distance
for future using.
(Suitable for sliding head)
Turn both prism houses to adjust interpupillary
distance till the image through both eyepiece
syncretic.
The “。”  on eyepiece tube point to reticle ,
then the number is interpupillary distance. (Figure
17)
Interpupillary distance: 50-76mm
 Please remember own interpupillary distance
for future using.
(Suitable for sliding head)
3-7 Adjust center of condenser
1. Turn the condenser up-down knob  with the
direction showed to make the condenser to top
position. (Figure 18)
2.Slide10Xobjectiveintolightpathtofindimage.
3.TurntheringonviewfielddiaphragmtoMin..
At this time, you may find image for the
diaphragm.
4. Adjust the condenser holder knob to make the
diaphragm image clear.
5. Adjust the adjusting-screw on condenser  to
make the diaphragm image center. (Figure 19)
6. Open the view field diaphragm slowly. If the
diaphragm image is always at center and inscribed
with view field, then the condenser has been
centered.
7. During operation, please open view field
diaphragm a little to make the its image exscribed.

D1 series
3-8 View field diaphragm（Figure 19）
The view field diaphragm can prevent the light
diameter into condenser in order to remove
varied-light and strength the image. When the image
of view field diaphragm is just outside of view field,
the objectives can provide optimal performance to
get the clearest image.
3-9 Aperture diaphragm (Figure 20&21)
1. Aperture diaphragm determines aperture number
of illumination. Only when the aperture number
for illumination and objective is matching, you
can get the better resolution and contrast of image
and to increase depth of field.
2.Asthecontrastofsampleformicroscopeisvery
low, please turn the knob  during operation to let
the arrowhead point to number chip which shows
same magnification as objectives. That means
adjust the aperture diaphragm of condenser to
70-80% of objective aperture. If necessary, take
off the eyepiece and observe through eyepiece
tube and adjust knob  till finding the image

3-10 Use objective (100X) with oil
1. Use objective 4X to find image.
2. Drop oil  on sample. (Figure 22)
3. Turn the nosepiece counter-clockwise and slide
the objective 100X into light path. Then turn fine
adjusting knob to make image clear.
Make sure no bubble inside oil because any
bubble will affect image quality.
A. Please take off eyepiece and open view field
diaphragm and aperture diaphragm thoroughly,
then observe through eyepiece tube to check
bubble. (If the edge of the objective is round and
bright, there is without bubble.)
B. Please turn nosepiece softly and let the 100X
objective swing the oil to wipe off the bubble.
4. After use oil, please clean the objective with 3:7
mixed alcohol and ether or dimethylbenzene on
cloth. Also please wipe off the oil on sample.
 Do not turn other objective into light path
before wipe off oil on sample to avoid oil
moisten objectives.
 It will dissolve glue on prism if use
more dimethylbenzene.
3-11 Use filter (Figure 23)
Filter can make the background of image more
suitable. No filter for the LED version.
There are blue, green, yellow and neutral for
selection.
3-12 Replace fuse (Figure 24)
Put the power switch on “OFF” before replacing the
fuse. Cut the power supply first, then screw off the
fuse group from the fuse base with “-”
screwdriver. And put a new fuse and screw on the
fuse base. (Fig.24)
 Specification: 250V，3.15A.

3-13 Select light path (Figure 25)
The light path selecting levercontrols the prismatic
between binocular and trinocular. When the lever 
is in the most inside, light enters the binocular fully;
when the lever  is in the most outside, the
prismatic is 8:2 for binocular and trinocular. Usually,
push the lever  to the most inside when using the
binocular and push it to most outside when using the
trinocular (TV or Photo). (Fig.25)
3-14 Set Video device (Figure 26)
1. Loose the lock-screw  on trinocular head and
take off the cap  on third tube. (Fig. 26)
2. Take off the cap on TV adapter  and screw the
adapter into third tube with the direction showed
and lock it.
3. Loose the lock screw  on TV adapter and take
off C-mount , and screw in CCD or vidicon.
Then screw the whole adapter into TV adapter and
lock the screw .
4. Pull the light path selecting lever  to the most
outside for observation for binocular. Adjust the
tube  till image clear
3-15 Set photo adapter (Figure 27/28)
1. Loose the lock-screw  on trinocular head and
take off the cap  on third tube.
2. Set the photo adapter into third tube with the
direction showed and lock the screw . (Fig. 27)
3. Loose the lock-screw  and take off photo tube.
4. Set 3.2X photo eyepiece  into the eyepiece hole
 and put on photo tube , then lock on screw .
5. Observe through binocular till image clear, then
pull the light path selecting lever  to the most
outside. And operate under the manual of camera.
