6. Operating Instructions
6.1 Connecting the Microscope
Once the software is installed and the microscope is physically connected to your device, open the installed application. The live view from the microscope should appear on your screen.
6.2 Adjusting Magnification and Focus
The microscope offers 40X to 1000X stepless magnification. Rotate the focus wheel on the microscope body to adjust the magnification and bring the object into clear focus. For optimal viewing, adjust the distance between the microscope lens and the object.
6.3 Controlling LED Illumination
The microscope is equipped with 8 built-in LED lights. Use the LED dimming wire control knob located on the USB cable to adjust the brightness of the lights. The diffuser ensures soft, non-dazzling illumination of the viewed object.
6.4 Capturing Images and Videos
With the installed software, you can capture still images (screenshots) and record videos. Please note that the SNAP and ZOOM buttons on the microscope body are only functional with Windows systems, as the proprietary software for these functions is designed for Windows.
6.5 Using Measurement Software (Windows Only)
The measurement software included with the Windows application allows for precise measurements of magnified objects. This feature is exclusively available for Windows users.
