The operation method of microscope
1. Lighting
When open the power switch, the light bulb will be bright. Rotating brightness knob to adjust the brightness of the field.

2. Place specimen slides
Put glass slide on the stage, put the cover glass upward, part the specimen holder shrapnel with fingers,and hold the glass slide.

3. Use 10X objective to focus
Rotate the converter, move the 10 x object lens to optical lattice (when rotated, the converter will automatically locate object lens, focus the image on specimen by turning the coarse and the fine focal handwheel. Selecting the appropriate position,when the movement direction of the object stage and the focusing handwheel is matched. Coarse fine-tuning hand wheel adjust the stage lifting, and fine-tuning hand wheel is used to adjust the sharpness of the measured object imaging.

4. Eyepiece diopter adjustment

According the left and right eyes’ diopter to adjust diopter adjustment ring. Users can make full use of the advantages of the objectives and use the function of parfocality.
1） Move the 40 x（or 10×→4×，40×→100×） object lens to optical path, 2） turn the coarse and fine focal handwheel to focus the specimen.
Repeat the above steps to see images by left and right eyes at the same time.

5. Condenser vertical position adjustment
Using the condenser lifting handle to transfer it to the upper limit, then
lower it down a little bit. If you find scattering field background images, you can adjust the condenser slightly up and down,to make it disappeared.

6. Selection of the objectives
Rotate lens converter, select the desired objective magnification, adjust the according to the selected object lens.

7. Aperture diaphragm adjustment
Put the regulating rod dial of condenser aperture diaphragm to the optical path to make the ratio of the objective same number.

8. Aperture diaphragm adjustment

1. The regulating rod dial of aperture diaphragm changes its scale. If a narrow aperture, brightness and resolution will be lower, and the contrast and depth of field will increase. On the contrary, if a large aperture, brightness and resolution will be increased, while the contrast and the depth of field will be reduced.
2. In order to obtain ideal and appropriate contrast image, you can make the aperture diaphragm adjustment transferred to the numerical aperture of the objective of 70% to 80%. Aperture diaphragm controls the numerical aperture of the condenser. Don't use it to adjust the brightness,you can use brightness control knob to adjust the brightness instead.When observing the aperture diaphragm,please move the eyepiece, use the binocular tube to observe directly.
3. Numerical aperture of the condenser is said in the corresponding objective multiple,40 x / 0.65 tag is refers to the magnification of 40 x, numerical aperture of 0.65, the position of the aperture adjustment lever.

9. Oiled observation 1

Labeled "oil" font object lens for oil immersion objective. When using the oil objectives,they should be oiled by special microscope liquid between the lens and cover glass. Make sure that the cap is tight after using the oil.The cap may be a little loose after long-term use.So you should inspect the cap regularly to protect the oil from spilling. Don't extrude container excessively, it may be the cause of oil overflowing suddenly from the container. In the using process,please wipe the oil on the container.

10. Adjust the torque of coarse focusing handwheel

The coarse focusing handwheel looseness is adjustable.If you want to increase the torque, you can twist the torque adjustable ring of the coarse focusing handwheel counterclockwise. On the contrary, twist it clockwise. Don't tune it too loose, or the stage will be dropped automatically.

11. Troubleshooting Guide

Problem	Causes	Remedy
1) The bulb does not light.	Power cord of the power supply unit is unplugged.	Plug in the power cord into a power outlet.
	Main switch of the power supply unit is not ON.	Set the main switch to “I” (ON).
	The fuse is burnt out	Replace the fuse.
	The bulb is burnt out.	Replace the bulb.
2) The bulb lights but the field of view is dark.	The voltage is too low	Increase light intensity to an optimum voltage.
	Condenser is not well positioned.	Adjust the condenser height until the field iris diaphragm image is formed in the specimen plane.
	Condenser is not centered.	Center the condenser so that the field iris diaphragm image is centered in the field of view.
	Revolving nosepiece is not in a click position.	Make sure that the revolving nosepiece clicks properly into place.
	Field iris diaphragm is not opened wide enough.	Open the field iris diaphragm sufficiently.

	Too many filters are used.	Reduce the number of filters to the minimum required.
3) Field of view is obscured or not evenly illuminated.	The objective that falls outside the condenser’s illumination range is used.	Use a condenser that matches the objective.
	Field iris diaphragm is not properly centered.	Center the field iris diaphragm correctly.
	Field iris diaphragm is stopped down too far.	Open the field iris diaphragm sufficiently.
	Revolving nosepiece is in an intermediate position	Engage the revolving nosepiece at a click stop.
	A filter is stopped in an intermediate position.	Set the filter at the appropriate position.
	The frost filter is not engaged.	Engage the frost filter.
4) Dirt or dust is visible in the field of view.	Dirt/dust on the specimen.	Clean thoroughly.
	Dirt/dust on the Sensor.
	Dirt/dust on a mirror unit.
	Dirt/dust on the optical element.
	Condenser is not correctly positioned and the frosted filter or filter is focused.	Adjust the condenser height until the field iris diaphragm image is formed in the specimen plane.
5)Image glares	Condenser is raised too high.	Lower to the proper position.
	Aperture iris diaphragm is stopped down too far.	Open the aperture iris diaphragm.
6)Visibility of observe image is poor, Image is not sharp Contrast is poor,Details are poorly visible.	Objective in use is not designed for DIS series.	Replace with an objective designed for DIS optics.
	Front lens of the objective is dirty	Clean the objective.

	Inappropriate slide or cover glass thickness.	Replace with glass of appropriate thickness.
	Dirt/dust on glass components (condenser, objective, Sensor, )	Clean thoroughly.
	Phase plate are not centered.	Center it.
7) Image is blurred.	Objective is engaged incorrectly in the light path.	Make sure that revolving nosepiece clicks Into place correctly.
	Specimen is tilted with respect to the stage.	Place the specimen correctly on the stage.
8) The coarse/fine adjustment knobs will not rotate easily or at all.	The rotation tension adjustment ring is too tight.	Loosen the ring optimally.
9) The stage lowers by its own weight.	The rotation tension adjustment ring is too loose.	Tighten the ring optimally.

The following symbols are used to set off text in this instruction manual.


3. Safety Precautions

3.1 After the equipment has been used in an observation of a specimen that is accompanied with a potential of infection, clean the parts coming in contact with the specimen to prevent infection.
Moving this product is accompanied with the risk of dropping the specimen. Be sure to remove the specimen before moving this product.
In case the specimen is damaged by erroneous, promptly take the infection prevention measures.
3.2 The microscope is provided with a simplified waterproof mechanism. Therefore, if culture liquid or water is split on the stage, revolving nosepiece or microscope frame, damage to the equipment or an electrical shock may result. Immediately wipe the liquid or water off if it is spilt on them.
3.3 The microscope is not covered by warranty in terms of laser safety. The user should assume liabilities for any consequence of user modification,
3.4 The surfaces of the lamp housing will become extremely hot during long-time operation. Be sure to keep the flammable stuffs such as paper, alcohol, oil away from the lamp house to avoider.
3.5 When using the microscope, route the power cord away from the lamp housing. Should the power cord come in contact with the hot lamp housing, the power cord could melt and cause electric shock.
3.6 To avoid potential shock hazards and burns when replacing the light bulb, set the main switch to “O” (OFF) then disconnect the power cord from the wall outlet in advance. Whenever you replace the bulb during use or right after use, allow the lamp housing and bulb to cool before touching.
3.7 Electric shock warning:
