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
oll through all the available calculations and solutions. You
scr
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, Roofing, Studs, Tile and Grout
