• Try different baud rates (9600 is most common)
• Ensure no other applications are using the same COM port
• Use Device Manager to verify COM port availability

Data Reading Problems

• Check scale data format in console log
• Verify scale is configured to send continuous data
• Some scales require manual triggering for data transmission
• Ensure proper RS232 wiring (TX, RX, GND)

Interface Display Issues

• Increase screen resolution or decrease Windows scaling
• Minimum display resolution: 1400x800
• For smaller screens, consider using Windows magnifier
• Ensure graphics drivers are up to date

Performance Issues

• Close other resource-intensive applications
• Check Windows Task Manager for high CPU usage
