Microscope assembly

  • Open the battery compartment and insert the battery into the battery compartment matching the indicated polarity. The battery has to be fully charged before turning the microscope on for the first time. Plug the power cable into the power cable socket on the microscope body (7) and connect it to a power source. The battery status indicator (4) will turn red. Once the battery is fully charged, the indicator will go out. You can now disconnect the microscope from the power source and turn it on. The fully-charged battery allows you to use the microscope for 2.5 hours. The illumination will grow dim and the image quality will decrease to inform you that the battery is low. Charge the battery, as described above.
  • A micro SD card (purchased separately) is required to save captured images and recorded videos. Turn the microscope off and insert the micro SD card into the corresponding slot on the microscope body until it locks in place with a click. Do not apply excessive force when inserting the micro SD card. Try rotating the card, if it does not lock in place with ease. Format the card before using it. To turn the microscope on, open the LCD display or press the power button (17). To turn the microscope off, fold the LCD display or press the power button (17) again (refer to Power saving section for more information).

Calibration

  • Before calibrating the microscope, turn the grid display on. To do so, select On from Options > XY Guide. By default, the grid is visible. Place the calibration scale on the stage and focus your view. Make sure that the vertical axis of the grid is parallel to scale divisions and capture an image. Double-click the image thumbnail to open it in a separate window.

  • Click the corresponding icon on the toolbar to begin calibration. Using your mouse, choose two points on the image (you have to know the actual distance between these two points). Once you choose the second point, a dialog window will open, where you have to enter the known distance in the Actual dimension field. The application will automatically calculate the magnification of the image. Click OK  to close the dialog window. The calculated magnification will be displayed in the Magnification field.
    Note: Chosen points should form a horizontal line.

  • You can check calibration results by measuring the same distance with the Straight line tool. Click the measurements icon, choose the Straight line tool and draw a similar line on the image. If the measured distance is equal to the actual distance, calibration has been successful.

Recalibration

The calibration process has to be repeated if the magnification or focus has been changed during observations.
Click the corresponding icon on the toolbar again and select Reset picture magnification from Reset magnification. Repeat the calibration process, as described above. Change the magnification and capture a few images. Double- click one of the thumbnails to open the resulting image in a preview window. Click the calibration icon on the toolbar and select Set picture magnification from Set magnification. Enter the current magnification in the dialog window that appears and click OK.
If you want to use the same magnification when capturing images in the future, click the calibration icon on the toolbar and select Set capture magnification from Set magnification.

Measurements

  • It is recommended to calibrate the system before proceeding with measurements. Straight line. Press and hold the left mouse button to start drawing a line. Release the left mouse button to complete the line.
  • Continuous Line. Press and hold the left mouse button and draw a line. Release the left mouse button to complete the segment. You can continue adding more segments to the free-form line.
  • Radius Circle. Draw a straight line on the image. The application will automatically calculate the radius, as well as circumference and area of the corresponding circle.
  • Diameter Circle. Draw a straight line on the image. The application will automatically calculate the diameter, as well as circumference and area of the corresponding circle.
  • Three Points Angle. Press and hold the left mouse button to draw a line on the image. Release the left mouse button and draw another line. The application will automatically calculate value of the resulting angle.

Draw and text

Portable Capture allows you to add drawings and textboxes to your images. Open an image in a preview window and click the Pencil icon on the toolbar. Select one of the tools from the drop-down menu and draw something on the image. By clicking the TT icon on the toolbar, you can edit font type and color to be used in textboxes.

Care and maintenance

Never, under any circumstances, look directly at the Sun, another bright source of light or at a laser through this device, as this may cause PERMANENT RETINAL DAMAGE and may lead to BLINDNESS. Take necessary precautions when using the device with children or others who have not read or who do not fully understand these instructions. After unpacking your microscope and before using it for the first time check for integrity and durability of every component and connection. Do not try to disassemble the device on your own for any reason. For repairs and cleaning of any kind, please contact your local specialized service center. Protect the device from sudden impact and excessive mechanical force. Do not apply excessive pressure when adjusting focus. Do not overtighten the locking screws. Do not touch the optical surfaces with your fingers. To clean the device exterior, use only special cleaning wipes and special optics cleaning tools from Levenhuk. Do not use any corrosive or acetone-based fluids to clean the optics. Abrasive particles, such as sand, should not be wiped off lenses, but instead blown off or brushed away with a soft brush. Do not use the device for lengthy periods of time, or leave it unattended in direct sunlight. Keep the device away from water and high humidity. Be careful during your observations, always replace the dust cover after you are finished with observations to protect the device from dust and stains. If you are not using your microscope for extended periods of time, store the objective lenses and eyepieces separately from the microscope. Store the device in a dry, cool place away from hazardous acids and other chemicals, away from heaters, open fire and other sources of high temperatures. When using the microscope, try not to use it near flammable materials or substances (benzene, paper, cardboard, plastic, etc.), as the base may heat up during use, and might become a fire hazard. Always unplug the microscope from a power source before opening the base or changing the illumination lamp. Regardless of the lamp type (halogen or incandescent), give it some time to cool down before trying to change it, and always change it to a lamp of the same type. Always use the power supply with the proper voltage, i.e. indicated in the specifications of your new microscope. Plugging the instrument into a different power outlet may damage the electric circuitry of the microscope, burn out the lamp, or even cause a short circuit. Children should use the device under adult supervision only. Seek medical advice immediately if a small part or a battery is swallowed.

Battery safety instructions

Always purchase the correct size and grade of battery most suitable for the intended use. Always replace the whole set of batteries at one time; taking care not to mix old and new ones, or batteries of different types. Clean the battery contacts and also those of the device prior to battery installation. Make sure the batteries are installed correctly with regard to polarity (+ and –). Remove batteries from equipment that is not to be used for an extended period of time. Remove used batteries promptly. Never short-circuit batteries as this may lead to high temperatures, leakage,  or explosion. Never heat batteries in order to revive them. Do not disassemble batteries. Remember to switch off devices after use. Keep batteries out of the reach of children, to avoid risk of ingestion, suffocation, or poisoning. Utilize used batteries as prescribed by your country’s laws.
