The Whiten vibrating screen model may be invoked from the Excel formula bar with the following function call:

=mdUnit_Screen_Whiten(Parameters as Range, Size as Range, Feed as Range, Rows as Range)

Invoking the function with no arguments will print Help text associated with the model, including a link to this page.
