T
he  (CMP EZ) is the newest in
Calculated Industries′ line of award-winning Construction Master
Plus construction-math calculators. The big dierence between the
CMP EZ and the other models is that, in addition to many more built-in
calculations, the CMP EZ is a Prompting Calculator.
With a Prompting Calculator, you select a function and then scroll
through a series of prompts for quantities, measurements, placement,
materials and other possible inputs. After entering the inputs, you can
then
scroll through all the available calculations and solutions. You
can also change an input (or multiple inputs) and then re-solve the
problem, instantly seeing how the new entry changes calculations
without having to re-enter the entire problem.
The  has Basic and Advanced solutions
(lengths, angles, quantities, etc.) for these construction calculations:
● Rafters
● Hip/Valley Rafters
● Jack Rafters
● Stairs
Other solutions include
● Square-Ups, Areas and Volumes
● Circular
● Arcs
● Rake Walls
● Arch Studs
● Balusters ─ Cap Wall and Open Wall
● Elliptical Arches
● Crown Molding
● Compound Angles
● Polygons
● Spacing
● Material Calculations for Blocks, Drywall, Fencing, Footings,
Pavers, Roong, Studs, Tile and Grout

AUTO SHUT
-
OFF AND AUTO SHUTDOWN
The LCD display on your calculator is designed to shut o after 4 minutes
of non-use. If the display powers o, just press the
O
key to power it
back on. All values are maintained. Your most recent entry will be displayed
and you can scroll through or continue to enter values for the same
calculation you were working on before the display shut o. After 4 hours
of non-use, the calculator will shut down and all temporary settings and
values are cleared.
U.S. AND METRIC MODES
The  can be used in either U.S. Mode (the
calculator’s default setting), which uses inches, or Metric Mode, which uses
millimeters, as a basis for entries and calculations. To change the Mode,
go to Preferences, using the Extras function (
CN
).
DEFAULT VALUES
The table below shows the calculator’s U.S. and Metric Default Values.
Default Values can be changed by entering a new value. The new Default
Value will remain until you change it or reset it to zero. An All Clear
(
Cx
) will reset values to the calculator’s Default Values.
Roong calculations are based on 4' x 8' Sheathing Size.

CONSTRUCTION EXAMPLES
For each of the functions shown in the User’s Guide there is a box showing
all of the required entries, optional entries and possible solutions for
that function. You can also quickly see the prompts for entries and possible
solutions for each function on the calculator by accessing the function and
then scrolling through the prompts and solutions, with repeated presses of
the
e
key, the
^
key or the
v
key.
 After scrolling through all your entries and solutions, the calculator
will display REPEAT briey before returning to the rst input prompt. You
can then scroll through and view (or change) entries and solutions. It’s
recommended that you allow the REPEAT message to disappear before
continuing to scroll through the function. Not doing so will skip the rst

determines which type of calculation will be used. The default is Target

• Target Riser Height: Use this setting to get a stair calculation that will get as
close to the stored Riser Height as possible. The calculated Actual Riser Height
will either be shorter or taller than the Target Riser Height.
• Maximum Riser Height: This is used when local building codes prohibit risers
greater than this value. The calculated Actual Riser Height will not exceed the

Inch x Inch – area answers will remain in this
format (Square Inch), but if units entered are
dierent – e.g., Inches x Feet – area answers will
be displayed in Square Feet.
– SQUARE FEET: area answers always displayed
in Square Feet, regardless of unit entry – e.g.,
Inches x Inches = Square Feet.

answer will be displayed in Cubic Yards.
– CUBIC YARDS: volume answers always
displayed in Cubic Yards, regardless of unit entry
– e.g., Feet x Feet x Inches – volume answer will
be displayed in Cubic Yards.
– CUBIC FEET: volume answers always displayed
in Cubic Feet, regardless of unit entry – e.g.,
Inches x Inches x Inches = Cubic Feet.
