If the software fails to "Refresh Communication," check your Device Manager. If a question mark appears next to "3197," you may need to manually point the Windows Wizard to the driver folder located at C:\Program Files\HIOKI\3197\drivers Compatibility
If the device is not recognized, manually reset the dedicated device driver via the Windows Device Manager by pointing it to the driver folder within the application directory (typically C:\Program Files\HIOKI\3197\drivers ).
