This User’s Guide helps you solve common construction math and

material estimation problems using the latest

Construction Master Pro

calculators—three of the most powerful feet-inch-fraction calculators

to date:

The

Construction Master Pro III

Series —

1. Construction Master Pro v3.0 (#4065)

2. Construction Master ProTrig v3.0 (#4080)

3. Construction Master Pro Desktop v3.0 (#44080)

IMPORTANT: The

Construction Master Pro Trig

The

Construction Master Pro

line includes the most advanced feet-

inch-fraction calculators

designed specifically for building pro’s!

The

Pro

calculators handle practically any problem involving meas-

urements and can be used to save time, prevent errors, and accu-

rately perform common building projects such as: estimating con-

crete volume, squaring-up foundations, framing roofs, ordering lum-

ber, building stairs, walls, laying driveways, carpet or floor covering,

figuring precise angle calculations, or simply working in feet-inch-

fractions or decimal feet!

Your Calculator Helps You Solve:

• Dimensional Math Problems

• Conversions Between Feet-Inch-Fractions, Decimal Feet,

Decimal Inches, and Yards

• Imperial/Metric Conversions

• Problems Involving All Common Fractions —

1/2” to 1/64”!

• Area/Volume Calculations

• Board Feet/Lumber Calculations

• Circle Calculations

• Column/Cone Area and Volume

• Compound Miter Cuts for Crown Moulding

• Material Estimations and Costs

• Polygons

• Rake-Walls

• Right Angle/Triangle Solutions

• Roofing Materials

• Stair Layout (Risers/Treads)

• Studs

• Weight/Volume Conversions

Pro and Desktop Models (

NOT AVAILABLE ON TRIG MODEL

#4080)

Also Solve:

• Block/Bricks, Concrete Footings and Drywall

• Instant Square-up, Perimeter, Wall Area, Room Area and

Volume

KEY DEFINITIONS

Basic Operation Keys

On/Clear

— Turns power on. Pressing once clears

the display. Pressing twice clears all temporary

values.

OTurns all power off, clearing all non-permanent

registers.

+ – x Arithmetic operation keys.

÷ =

%Four-function (+, -, x, ÷) percent key. (See page 33

for examples.)

0– 9and •Keys used for entering digits.

)(DESKTOP ONLY)Enters “00” to save keystrokes (e.g.,

1 ) to enter 100).

Backspace Key

— Used to delete entries one key-

stroke at a time (unlike the ofunction, which

deletes the entire entry).

Convert ÇKey —

Unit Conversions and Second Functions

The Çkey is to convert between measurement units or to access

the second functions listed below:

Ç x

Clear All

— Clears all values, including Memory.

Resets all permanent entries to default values

(except Preference Settings which are retained).

Note: Use only when necessary, as it resets all stored values to

factory defaults. See page 88 for a listing of default values.

Ç %

— Squares the value in the display. For example,

to square the value 10, enter 1 0 then Ç %.

Ç B

Square Root Function ( )

— Used to find the

square root of a non-dimensional or area value

(e.g., 1 0 0 Ç B = 10).

Ç /

x10y

— Allows entry of an exponent. For example,

8 Ç / 1 4 is 8 times 10 to the 14th power.

Ç ÷

1/x

— Finds the reciprocal of a number (e.g., 8

Ç ÷ = 0.125).

Ç –

Change Sign (+/–)

— Toggles the sign of the dis-

played value to positive or negative.

Ç +

Pi (

)

— Constant = 3.141593

Ç •

Degrees:Minutes:Seconds

— Converts between

D:M:S and decimal degree formats.

Ç 0

Total Cost

— Calculates total material cost given a

unit dimension and an entered Per Unit Cost.

Ç ß

Access Preference Settings

— Used to access

various customizable settings, such as dimensional

answer formats (see Preference Settings on page

89).

Memory and Storage Functions

Your calculator has two types of Memory:

1) basic memory or semi-permanent, cumulative µ;

2) non-cumulative Storage Registers (M1-M3).

Semi-Permanent Memory

— Adds any displayed

number, dimensioned or unitless, to the semi-per-

manent, cumulative Memory. Values can be sub-

tracted from this Memory using Ç µ

(M–)

. ®

µwill display the value in the Memory. ® ®

will display and clear the value in the Memory. Ç

®will clear the cumulative Memory without dis-

turbing the existing display.

ß 1 – 3

Storage Registers (M1) through (M3)

— Stores

the displayed value in non-cumulative, permanent

Memory (e.g., 1 0 ß 1). Good for storing a

single value, for future reference (® 1 = 10).

Note: Non-cumulative means it only accepts one value (does not

add or subtract) and a second entered value will replace the first.

Permanent means the value is stored even after the calculator is

shut off. To delete a stored value, enter a new value or perform a

Clear All
