The black diamond on the top scale starting at 19.2 inches is for truss layouts for 8-foot sheet goods—also referred to as the "black truss" markings. Originally the 19.2 was used in metric layouts. If you divide five into 96 inches (8 feet), it will give 19.2 inches—in other words, 5 trusses per sheet.
I hope this helps!

Those diamond marks are for proper spacing of engineered roof trusses.

Trusses not rafters. Rafters are every 16".
