T

he ConstruCtion Master Plus EZ (CMP EZ) is the newest in

Calculated Industries′ line of award-winning Construction Master

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.

1

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 & Open Wall

● Elliptical Arches

● Crown Molding

● Compound Angles

● Polygons

● Spacing

● Material Calculations for

Blocks, Drywall, Fencing,

Footings, Pavers, Roong,

Studs, Tile and Grout

sequence, pressing once clears the last entry and what is

displayed. Pressing twice clears all non-permanent values.

Within a prompting input sequence, pressing once clears

the entry and leaves the prompt displayed. Pressing twice

exits the prompt function, but does not clear non-permanent

values. A third press clears non-permanent values.

Within an output sequence, pressing once exits the prompt

function, but does not clear non-permanent values. Pressing

twice clears non-permanent values.

o

Off – Turns all power off. Clears all non-permanent memory.

Using the Construction Master Plus EZ

This Pocket Reference Guide has step-by-step keystroked examples for

some of the CMP EZ’s functions. You can see, and download, a complete

illustrated User’s Guide with examples for all of the CMP EZ’s functions at

www.calculated.com/4067/UG.

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.

15

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

). For keystroked

examples on changing and setting Preferences, see the User’s Guide.

16

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
