24 — CONSTRUCTION MASTER PROStair KeyThe Construction Master Pro easily computes stair layout solutions.Given values for rise and/or run, your calculator will compute riser,tread, stringer and angle of incline values simply by pressing the[Stair] key.[Stair]A multi-function key that uses a stored desired riser height, desiredtread width, and rise and run values to compute and display the fol-lowing:Press Result1 Riser Size2 Number of Risers3 Riser Overage/Underage4 Tread Width5 Number of Treads6 Tread Overage/Underage7 Stringer Length8 Angle of Incline˛˛ Note: Default values are 7-1/2 inches for Desired Riser Height and10 inches for Desired Tread Width.˛˛ Note: It is not possible for the calculator to include thenose/overhang measurement. Thus, you need to adjust for thismeasurement per l ocal codes.[Stor] [Stair] — Store Desired Riser HeightStores a value other than the default desired stair riser height of7-1/2 inches (e.g., 8 [Inch] [Stor] [Stair] stores an 8-inch desiredstair riser height). To recall the stored setting, press [Rcl] [Stair].[Stor] [m] — Store Desired Tread WidthStores a value other than the default desired stair tread width of 10inches (e.g., 12 [Inch] [Stor] [m] stores a 12-inch desired stair treadwidth). This value is used when the run or the rise has not been en-tered (used as the tread width when a run has not been entered andwith the run value to solve the stair parameters when a rise has notbeen entered.) To recall the stored setting, press [Rcl] [m].
