Before Use

Notice

1. Microscope should be stored in a dry and clean environment. Do not expose the microscope to the direct sunlight. Avoid high temperatures and violent vibration.
2. This microscope is a precision instrument. Handle with care. Avoid impact and abrupt movement during transportation.
3. To keep the image clear, clean any fingerprints or stains on the surfaces of the lens.
4. Never turn the left and right focusing knob in the opposite direction at the same time. Microscope damage will occur.

Maintenance

1. All lenses must be kept clean. Fine dust on the surface of the lens should be blown off with hand blower or wiped off gently with a soft lens tissue. Fingerprints and oil marks should be cleaned with a tissue moistened with a small amount of a 3:7 mixture of alcohol and ether.
2. Never use organic solution to clean the other surfaces (especially the plastic surfaces). If necessary, please use a neutral detergent.
3. Once assembled, do not take the microscope apart as this may cause damage to the microscope.

Nomenclature

Assembly

Operation

Position the glass stage

1. Place the microscope base on a flat, firm surface and position the frosted stage plate on the base. (Figure 1)

Adjust the degree of tightness of the focusing arm

1. Check the coarse focus knob on either side of the main support. The coarse focus knob should turn easily.
2. If you want to adjust the degree of tightness of the focusing arm, you can hold one of the focusing knobs and turn another one to attain a suitable position. The degree of tightness relies on the direction to be turned. The clockwise direction is tight; counterclockwise is loose. (Figure 2)

Set the specimen slide

1. Set the specimen in the center of the stage plate. If necessary, clamp the slide with the clips.
2. To operate, plug the small round plug into the back of the base of the microscope and then plug the opposite end into the power outlet.

Adjust focusing knobs and diopter

1. Turn the focusing knob and observe the specimen through the right eyepiece until the image of the specimen is clear.
2. Observe the specimen through the left eyepiece and adjust the diopter ring 1 until the image is clear. (Figure 3)

Adjust the interpupillary distance

1. Adjust the two eyepieces along the direction of the arrow shown in Figure 4 until eyepiece feels comfortable and a single image is seen.
2. Use the left rheostat (dimmer knob) to adjust light intensity of the bottom (transmitted) light.
3. Use the right rheostat (dimmer knob) to adjust light intensity of upper (incidental) light.
