Stair Key
The
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, desired
tread width, and rise and run values to compute and display the fol-
lowing:

Note: Default values are 7-1/2 inches for Desired Riser Height and
10 inches for Desired Tread Width.

Note:
It is not possible for the calculator to include the
nose/overhang measurement. Thus, you need to adjust for this
measurement per local codes.
[Stor] [Stair] — Store Desired Riser Height
Stores a value
other than the default desired stair riser height of
7-1/2 inches (e.g., 8 [Inch] [Stor] [Stair] stores an 8-inch desired
stair riser height). To recall the stored setting, press
[Rcl] [Stair].
[Stor] [m] — Store Desired Tread Width
Stores a value
other than the default desired stair tread width of 10
inches (e.g., 12 [Inch] [Stor] [m] stores a 12-inch desired stair tread
width). 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 and
with the run value to solve the stair parameters when a rise has not
been entered.) To recall the stored setting, press [Rcl] [m].
