1. Remove all parts from their packing materials and retain the packaging in case you need to transport the
product.
2. Connect the power cord to a suitable power supply.
3.1 Basic Operation
1. Illumination controls, see figure 3
1.1. The power switch and transmitted / reflection
illumination toggle switch are located on the base. The
brightness control is located on the chassis. The
electrical system is fuse protected and the fuse holder
located on the power Inlet.
1.2. Press the power switch on the side of “I”, which
means the circuits is got through. If the light does not
appear to be ON, check the brightness control to see if
it’s on a sufficiently low setting. Then adjust the
brightness control until image can be observed
comfortably.
1.3. Note: Using the light at brightest setting will reduce
life span of bulb.

2. Focusing Controls, see figure 3
2.1. Focusing adjustment: Is accomplished by using the large coarse adjustment knobs located comfortably
on each side of the frame. Fine adjustment is accomplished using the smaller knobs located on the same
focus shaft. This coaxial arrangement allows for easy, precise adjustment without drift or discomfort.
2.2. Focus Control: Turning either of the coarse focus control knobs will raise or lower the stage. The smallest
graduation on the fine adjust knob index scale is 2μm of vertical.
2.3. Focus Tension Adjustment: The tension of the coarse focus is adjustable and preset at the factory for
ease of use. If you wish to adjust the coarse focus tension, first locate the tension adjustment ring. Turning
the ring toward the front of the microscope increases the tension, and toward the rear of the microscope
loosens it. Tension is too high if you experience physical discomfort.
2.4. Pre-focusing or Focus Stop Control: Use of this feature will insure that the short working distance
objectives don’t contact the stage or slide glass when using the microscope. Its use also simplifies
focusing. After focusing on the slide glass with the coarse adjustment, rotation of the lever toward the rear
of the microscope will set an upper limit on the coarse adjustment movement. After changing slide glass or
objectives, focusing is easily accomplished by rotating the coarse adjustment knob to reach the pre-
focused position, then making fine adjustments with the fine adjustment knob. Focusing movement with
the fine adjustment isn’t affected by using the pre-focusing lever.
3. Diopter and Interpupillary Adjustments
3.1. Diopter Adjustment Proper correction for
individual vision is accomplished via the diopter
adjustment located at the left eyepiece. Using the
10X objective, bring an image into focus with your
right eye only. Once the image is well focused,
observe with left eye, make fine adjustments with
the diopter adjustment ring to correct for your
vision.
3.2. Proper interpupillary distance, or the distance
between eyepieces, is crucial to the comfort of the
user. Adjusting the interpupillary distance is
accomplished through a “folding” action of the
optical head, at Figure 4, allowing for quick and
easy adjustment.

4. Rotatable Stage Controls, see Figure 5
4.1. Put a specimen on the stage, observe it using dividing
eyepiece and 10X objective.
4.2. Search one target in field of view, adjust it to the center
of view. See Figure 6 A.
4.3. Rotate the stage. If the stage out of center, the target
will encircle the center of circle. See Figure 6 B.
4.4. To center the center of circle in the field of view. Use
the two centering screws, the stage centering adjustment
can be finished. See Figure 6 C.
4.5. If other objectives out of center, you may adjust it using
the objective centering screws.
4.6. Tightening the stage setting screw can fix the rotatable
stage.
5. Condenser Alignment Controls.
5.1. Condenser Components: The condenser is located
below the stage, see Figure 7. Abbe condenser; its
mounting ring with lock screw and two large centering
screws at either side. The adjustment knob for raising
and lowering the condenser.
5.2. Condenser Alignment –to center the abbe condenser
in the optical light path. See Figure 8.
a. Turn the 10X objective to optics path, close iris
diaphragm and lower the Abbe condenser until
observe the image of iris diaphragm.
b. If the Abbe condenser optics axis offset optics
system axis, the image of iris diaphragm is similar
to figure 8A. The image may be out of focus and
out of center.
c. Adjust the sub-stage adjustment knob until the side
of image is clear. Adjust the Abbe condenser
centering screw until the iris diaphragm locate in
the center of field of view, see figure 8 B.
d. Open the iris diaphragm until the image is almost
as large as the field of view, see figure 8 C. Raise
Abbe condenser again for normal observe.

diaphragm, adjust the lamp transverse adjustment knob and vertical adjustment knob obtain a uniform
image. Adjust the condenser adjustment knob until a sharp image of the lamp filament is attained.
Refer to figure 10 for this step.
3. Reinstall the objective again.
4. Adjust the focusing control until the image clear. If brightness of field not equality, you may adjust the lamp
vertical adjustment knob and condenser adjustment knob slightly to make the brightness of field equality.
5. Reduce the field diaphragm, If it is not centered, move it to the center using the tool. Adjustment can be done by
opening the field diaphragm.
6. The filter seat contains a green, yellow, blue filter and ground glass, you may turn anyone to the light path to
obtain an image of good quality.
3.2 Changing the Light Bulb and the Fuse
1. Changing the lamp of the vertical illuminator. See figure.
a) Disconnect the power plug and wait to be sure the lamp
is cool. Loosen the set screw, remove the lamp house
from the body.
b) Pull the old lamp straight out of the socket. Insert the
new one into the same fixture. When installing the new
lamp, be careful not to touch the glass with your
fingers. The new lamp should be supplied in a plastic
protective envelope. If not, use a tissue or other medium
to grasp the lamp. This will prevent contamination from
your hand from reducing the lamp’s intensity and life.
Reinsert the lamp house into the body and retighten the
screw. If necessary, you may need to adjust the light
bulb transverse and vertical adjustment to center the
lamp.
