The (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.

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
