INTRODUCING

CONCRETECALC™

User’s Guide – 3

Basic Functions

[+] [–] [x] [÷] [=]

Arithmetic Operation Keys —Used to

perform arithmetic functions.

[%]

Percent — Four-function percent key.

[0] – [9] and [ • ]

Numeric Keys —Used to key numeric

values.

[Off]

Power Off — Turns all power off. Resets

the display and all non-permanent reg-

isters.

[On/C]

Power On/Clear — Turns on power.

Pressing once clears the last entry and

the display. Pressing twice in succes-

sion clears all temporary registers.

[Conv]

Convert —Used with the dimensional

keys to convert between dimensions.

Dimensions can only be converted with-

in the same convention (i.e., linear,

square or cubic). Also used to access spe-

cial functions when used in combination

with other keys as defined herein.

KEY DEFINITIONS

4– ConcreteCalc™

[ ]

Square Root —Used to find the square

root of a number.

Note: Attempts to find

the square root of a linear or volume

dimension will cause an “Error”.

[Conv] [ ]

x2 — Finds the square of the displayed

value.

Note: Attempts to find the square of

an area or volume dimension will cause an

“Error”

[M+]

Memory Add —Adds the displayed num-

ber to the value stored within the semi-

permanent Memory.

[Conv] [M+]

Memory Minus —Subtracts the dis-

played value from Memory.

[Rcl]

Recall —Recalls values stored in any

Memory.

[Rcl] [Rcl]

Memory Display/Clear —Displays the

value in Memory and clears the register.

[Conv] [Rcl]

Memory Clear —Clears the Memory

without changing the current display.

User’s Guide – 5

Dimension Keys

[Yds]

Yards —This is an entry and conver-

sion key. The entry can be a whole

number or a decimal number. Used with

the [Conv] key converts any other dis-

played dimensioned number to yards.

[Feet]

This is an entry and conversion key.

The entry can be a whole number or

decimal number. This key can also be

used in conjunction with the [Inch] and

[/] keys for entering values in Feet-

Inch format. For example, 6 feet 9-1/2

inches is entered as follows:

6 [Feet] 9 [Inch] 1 [/] 2

Repeated presses of this key during

conversions will toggle between Feet-

Inch and Decimal Feet formats.

[Inch]

This is an entry and conversion key.

The entry can be in whole or decimal

numbers. This key can also be used in

conjunction with the [/] key for enter-

ing values in Fractional Inch format.

Repeated presses of this key during

conversions will toggle between Fractional

Inch and Decimal Inch formats.

6– ConcreteCalc™

[/]

Fraction Bar —This key is used to

enter fractions. Fractions can be

entered as proper (1 or less — 1/2, 1/8,

1/16) or improper (greater than 1 —

3/2, 65/64). For example, to enter 1/2,

the key sequence would be: 1 [/] 2. If

the denominator (the bottom number)

is not entered, then the set fractional

level (1/16, 1/2, etc.) is used. [Rcl] [/]

displays the current fractional setting.

[Cu]

Cubic —This key is used with a dimen-

sion key (feet, inches, yards, meters,

etc.) to identify a value as being a vol-

ume. Example: 5 [Cu] [Yds].

[Sq]

Square —This key is used with a

dimension key (feet, inches, yards,

meters, etc.) to identify a value as being

an area. Example: 10 [Sq] [Feet].

[m]

Meters —This is an entry and conver-

sion key used to enter decimal meters

or to convert decimal meters from some

other dimensional format (when used

in conjunction with the [Conv] key).

User’s Guide – 7

[mm]

Millimeters —This is an entry and con-

version key used to enter or to convert

to decimal millimeters (when used in

conjunction with the [Conv] key).

[Weight]

This key is used to convert a dimen-

sioned cubic value or volume, to a

weight value using the [Conv] key and

the stored Weight per Volume (see

below). For example, 5 [Cu] [Yds]

[Conv] [Weight] equals 7.5 tons, or 10

[Weight] (tons) [Conv] [Cu] [Yds] equals

6.666667 cubic yards. Repeated press-

es of this key, after a cubic entry or

conversion, will toggle between tons,

pounds and kilograms.

[Conv] [%]

Weight per Volume—Used to set the

Weight per Volume. Can be programmed

as Tons per Cubic Yard, Pounds per

Cubic Yard, or Kilograms per Cubic Meter.

Default is 1.5 Tons/Cu. Yd. To set a dif-

ferent weight per volume, for example, 2

Tons/Cu. Yd, press 2 [Conv] [%]. Value

will be permanently stored. To recall

stored value, press [Rcl] [%].

8– ConcreteCalc™

Area/Volume Keys

[Length]

Enters the value for Length in dimen-

sion problems (e.g., for calculating area

or volume).

Note: This key is also used to

enter the length for “Square-ups” and the

“Run” for stair problems.

[Width]

Enters the value for Width in dimension

problems (e.g., calculating area or vol-

ume).

Note: This key is also used to enter

the width for “Square-ups.”

[Height]

Enters the value for Height in dimen-

sion problems (e.g., for calculating vol-

ume).

Note: This key is also used to enter

the “Rise” for stair problems.

[Vol]

Volume —Computes the volume

(Length x Width x Height) in Cubic

Yards based on entered Length, Width

and Height values. A second press will

display the area (in square feet) based

on entered Length and Width. Successive

presses will toggle the display between

the calculated area and volume.

[Conv] [Vol]

Area —Computes the area in Square

Feet based on entered Length and Width.

User’s Guide – 9

Square-Up & Drop Keys

[Sq-Up]

Square-up —Enters or computes the

“Square-Up” (or Diagonal) length based

on entered Length and Width values.

[Drop]

Computes the total drop (or fall) over

an entered Length, given an entered

percentage drop or inch drop per foot

value. Successive presses will act as a

“constant add,” for displaying succes-

sive drops.

Block/Footing Keys

[Block]

Number of Blocks —Computes the num-

ber of blocks or bricks needed after enter-

ing a wall area, or values entered in

Length and Height.

[Conv] [Block]

Block Size —Used to permanently set

the size of a single block or brick. The

default size is 128 square inches for an

8” x 16” block. To recall the stored

block area, press [Rcl] [Block].

[Ftg]

Footing —Used to compute concrete

volume of footings, walls, curbs, etc.
