Connect the power cable to the power input on the LCD screen and connect it to the network. The red LED will light up.
Turn the LCD screen on with the power on/off button; the LED light will change to green.
•
Insert the SD card (included) in the SD slot to view the image and save the resulting photos and videos.
Menu and functions
•
Use the buttons on the back of the LCD screen to control the camera functions and parameters. After modifying the
parameters, exit the interface to save data.
•
Press the Menu button to call up the menu. Use
↑↓

button once again to save the modified parameters and exit the interface.
Photo and video
•
Photo. Press the Snap button on the LCD panel to take a photo. The image will be saved on the SD card.
•
Video. Before recording a video, make sure that the SD card is formatted with the FAT32 file system and has enough free
space. You cannot take photos while recording a video. Enter the menu and select "Record Video" to record a video.
Basic settings
•
White Balance. In this parameter, you can adjust the color temperature. The default option is "Auto White Balance".
• Exposure
. In "Auto Exposure", you can set the exposure value. In "Manual Exposure", you can adjust the "time" parameter.
•
Color Adjustment. In this parameter, you can adjust saturation, hue, brightness, and contrast.
•
Monochrome. By selecting this parameter, you will see the image in different tones of a single color (e.g. shades of gray).
• Flip
. This feature allows you to flip the image horizontally or vertically.
Measurements
1. Cross Line
. You can select a cross line in four colors, turn the display on or off, and adjust the position of the center point of
the cross line.
2. Calibration
. The camera is calibrated by default, but you may need to recalibrate the camera.
•
Put the calibration slide on the stage so that the scale is placed horizontally on the screen. Adjust the focus as clearly as
possible.
•
Enter the Calibration menu. Drag a segment of the calibration ruler so that its ends are next to the marks on the physical
scale of the calibration slide. For maximum accuracy, try to capture as many scales as possible.
•
Example: The image above uses a ruler with 0.01 mm (10 µm) divisions under a 10x lens. The camera parameters are set
to: "magnification 10x", "units μm", and "length 40".
•
Each objective lens must be calibrated to take measurements at different magnifications.
•
After adjusting the parameters, exit the calibration menu to complete the procedure.
3. Recalibration
. The calibration process has to be repeated if the magnification or focus has been changed during observations.
Enter the Measurement menu. Select the magnification, adjust the start and end point, and then the value of the measured
segment will be displayed.
