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 0.01mm (10µm) 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.
