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
register. [Rcl] [M+] displays the value in
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.
