Example usage

using Itt.ScaleApi;

void HandleError(object? sender, UnhandledExceptionEventArgs e)
{
    Console.WriteLine(e.ExceptionObject);
}

void HandleReading(object? sender, ScaleMeasurementEventArgs e)
{
    Console.SetCursorPosition(0, 0);
    var stable = e.Stable ? "Stable" : "      ";
    Console.WriteLine($"{e.Weight,10:0.##} g {stable}");
}

using (var scale = SiScale.Create2400_8N1("COM8", HandleError))
{
    scale.WeightChanged += HandleReading;
    Console.ReadLine();
}
Console.WriteLine("Closed");

Notes on specific scales

Setra SI-2000S

• Manual is available at https://www.setra.com/hubfs/SI%20EL%20Manual%20v.C.pdf
• Default configuration is for 2400 8N1. Option to speed up to 9600 8N1 through mode/power button

Ohaus Adventurer ARA520

• Manual is available at https://dmx.ohaus.com/WorkArea/showcontent.aspx?id=3348
• Multiple modes available through front panel buttons
• Option to print when stable reading changes
• Default configuration is for 2400 7N2
• RS232 commands to scale seem to be ignored (cabling issue?)
• API is setup assuming "print when stable" is set
