T
he Construction Master Plus EZ (CMP EZ) is the newest in
Calculated Industries′ line of award-winning Construction Master
Plus construction-math calculators. The big difference 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 Construction Master Plus EZ 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

ConStrUCtion MaSter PlUS eZ
The Construction Master Plus EZ is a Prompting Calculator. To use it
you simply 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.
You can also use the
Ce
(Solve) function to skip any remaining
input prompts and go directly to the solution.
AUTO SHUT-OFF AND AUTO SHUTDOWN
The LCD display on your calculator is designed to shut off after 4 minutes
of non-use. If the display powers off, 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 off. 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 Construction Master Plus EZ 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

Note: Within Preferences, there is a setting for Riser Height that
determines which type of calculation will be used. The default is Target
Riser Height.
• 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

assigned the corresponding default Metric units
of the selected function.
3) Area Answer
Format
– STANDARD: if units entered are the same – e.g.,
Inch x Inch – area answers will remain in this
format (Square Inch), but if units entered are
different – 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.
– SQUARE YARDS: area answers always

Battery
The Construction Master Plus EZ uses one CR2025

actual use. Should your calculator display become very
dim or erratic, replace the battery.
Note: Please use caution when disposing of your old battery, as it
contains hazardous chemicals. Replacement batteries are available
at most discount or electronics stores. You may also call Calculated
Industries at 1-775-885-4900.
Battery Replacement Instructions
While the calculator is off, turn the calculator over and use a
#1 Phillips screwdriver to remove the battery holder screw located near
the center at the top. With the screw removed, pull battery holder out,
remove old battery, and slide new battery into holder. The negative side of
the battery should be facing you as you insert the battery holder into the
calculator. Replace screw using a #1 Phillips screwdriver.
Reset
If your calculator should ever "lock up," insert the tip of a paperclip or a
small diameter wire into the small Reset hole above the
o
key.
