4. Use the objective nosepiece (13) to rotate the objective lenses (12) until the 4x objective lens is directly over the specimen and clicks into place. Always start with
the lowest power objective (4x with this microscope) which gives you 40x power and work your way up to higher powers. At 40x power you will have the widest field
of view and the brightest image.
5. Look at the LCD screen while turning the focus knob (7) until the specimen comes into view. You may need to adjust the stage adjustment knobs (See Figure 8 above)
to center the specimen.
6. With the 4x objective lens, you can vary the power anywhere from 40x to 160x by using the digital zoom. To do this, use the Navigation Buttons on the LCD. Press
UP once and the zoom will adjust to 2x. Each additional press of the button will adjust the zoom by 1x, until it is at 4x. If you press UP again from 4x, it will go
back to 1x. Press DOWN (from 1x) and the zoom will adjust to 4x, then 3x, 2x and back to 1x.
7. To view in higher powers, rotate the objective nosepiece to the 10x or 40x objective. You will need to refocus after this change.
Tip: When changing objective lenses, lower the stage to ensure there is no contact between any objective lens and the stage surface which may result damage.
Using Filters
To change the filter settings, you rotate the filter wheel. (see Figure 9 below)
The filter wheel choices are as follows: Color: Red, Green, Blue - Clear: 1 mm, 3 mm and 6 mm apertures. Color filters work well with bright transparent specimens.
The different diameter apertures (1 mm, 3 mm, 6 mm) can help focus light on a section of a specimen, providing a more detailed image.
DIGITAL IMAGING
The LCD Digital Microscope II allows you to take snapshots and take short video clips, without the need to connect to a PC.
Note: Do NOT connect your microscope via USB while shooting images as doing so may cause damage to your microscope and/or computer.
The included 1G SD card allows for saving up to 625 still images (at highest resolution) or 20 minutes of video.
Settings
Adjusting the settings is a good idea before recording images with your LCD Microscope. Take note of your current settings by looking a the main screen.
