Vabiooth Professional Microscope VB-M006

1. Before Use

1-1. Operation

• As the microscope is a precision instrument, always use it with care. Avoid dropping or shaking during operation. Make sure the microscope is placed on a flat surface.
• Do not put the microscope in direct contact with the sun. Do not expose the microscope to high temperature, damp, or dusty environment.
• When moving the microscope, use both hands: typically one hand under the base and one hand on the arm (stand) of the microscope, and set it down carefully.

CAUTION:

• Be sure the microscope is unplugged before replacing the bulb or fuse and wait until the bulb has cooled down.
• This microscope has a built-in voltage transformer and can be used with a wide voltage range from 110 to 240V.
• Only use the power cord supplied with the microscope.

1-2. Maintenance

• Wipe the lens gently with a soft lens tissue. After every use with oil or fingerprints, clean the lens surfaces with lens paper or lens paper moistened with a little rubbing alcohol. If you do not have lens paper, use a lint-free towel or cloth.

CAUTION:

• Do not use organic solutions to wipe the surfaces of other components.
• If the microscope comes in contact with liquid, turn off the power immediately and wipe it dry.
• Never disassemble or service the microscope yourself.
• After using, cover the microscope with a dust cover.

3. Assembly

3-1 Install the Objectives

Install the objectives into the microscope nosepiece, starting from the lowest magnification to the highest, in a clockwise direction.

3-2 Insert the Eyepieces

1. Remove the eyepiece tube covers.
2. Insert the eyepieces into the tubes completely.

3-3 Install plug

Insert one side of the power plug into the back socket of the microscope.

4. Operation

4-1 Turn on

1. Insert the power plug into an outlet and turn on the microscope.
2. Adjust the light adjustment knob until you achieve the suitable brightness. (Refer to Figure 1, which shows the light control knob).

4-2 Set the specimen slide

1. Push the arm of the specimen holder back.
2. Insert the slide with the cover glass facing up, and then allow the arm of the specimen holder to move forward. (Refer to Figure 2, which illustrates placing the specimen slide).
3. Rotate the X and Y-axis knobs on the mechanical stage to move the specimen to the center, aligning it with the objective.

4-3 Adjust focus

1. Move the 4X objective into the light path.
2. Rotate the coarse-focusing knob until an image appears.
3. Turn the fine-focusing knob to make the specimen clearer. (Refer to Figure 3, which indicates the focus knobs).

Note: When using the 4X and 10X objectives, open the aperture diaphragm and field diaphragm to their widest positions.

4-4 Adjust tension of the focus

If the coarse focus knob is difficult to turn or the stage drifts downwards by itself, adjust the tension adjustment ring. Turn clockwise to tighten the controls or counterclockwise to loosen them. (Refer to Figure 4, showing the tension adjustment ring).

4-5 Adjust the interpupillary distance

When observing with both eyes, hold the bases of the eyepieces and rotate them around their axis until you see a single, unified field of view. (Refer to Figure 5, showing eye distance indication). The numbers on the left and right eyepiece bases should align to indicate the interpupillary distance.

4-6 Adjust diopters

Rotate one eyepiece to the "0" position using the white thread. Focus on a specimen clearly using only that eyepiece (this is for your dominant eye). Then, observe with the other eyepiece and rotate its diopter adjusting ring until the image is clear in that eyepiece as well. (Refer to Figure 6, illustrating diopter adjustment).

4-7 Adjust diaphragm

The diaphragm controls the amount of light entering the condenser, which can strengthen the image. For the clearest image, adjust the diaphragm so its image is just on the edge of the field of view.

4-8 Adjust aperture diaphragm

The aperture diaphragm determines the illumination's numerical aperture (N.A.). Matching the illumination N.A. with the objective's N.A. provides better resolution and contrast. If contrast is low, adjust the condenser's N.A. to 70%-80% of the objective's N.A. Adjust the upper diaphragm ring until the image appears as shown in Figure 7. For example, with a 40X objective (N.A. = 0.65), set the aperture diaphragm to approximately 0.52 (0.65 * 0.8). (Refer to Figure 8 for diaphragm adjustment).

4-9 Use the oil objective

Follow these steps for using the 100X oil objective:

1. Use the 40X objective to focus on the specimen.
2. Place a drop of immersion oil on the specimen. (Refer to Figure 9, showing oil position).
3. Rotate the nosepiece to place the 100X objective (oil) into the light path. Use the fine focusing knob to focus.

Important: Ensure there are no air bubbles in the oil.

To remove air bubbles:

• Remove the eyepieces. Open the aperture and field diaphragms fully. Observe the edge of the objective from the tube without the eyepieces.
• Slightly rotate the nosepiece and swing the oil objective a few times to remove air bubbles.

After using the oil objective, clean the 100X lens with clean lens paper and rubbing alcohol if the oil does not come off easily.

Using the Filter

Filters can soften the background. A frosted filter is included. A polarizer can also be placed in this position when using the optional simple polarizing set.

7. How to install the monitor or camera?

To install a monitor or camera:

1. Rotate the head of the tube counterclockwise; the bottom of the tube is twisted onto the machine.
2. The tube will then divide into two parts: one for the 23.2mm ocular port or tube, and the other for the C-Mount.

The monitor fits for the 23.2mm tube, while the camera is typically C-Mount.

Monitor Operation:

• Turn on the power button.
• Select the AV1 channel.
• Use the monitor's "M" button to adjust BRIGHTNESS, CONTRAST, COLOUR, ZOOM, TCON, and LANGUAGE.
