INTRODUCING HEAVYCALC™

User’s Guide – 3

Basic Functions

[+] [–] [x] [÷] [=]

Math Operators —Used to calculate

math problems.

[%]

Percent — Four-function percent key.

0 – 9 and [ • ]

Numerical Digits and Decimal Point

Used for keying in numbers.

[Off]

Power Off— Turns all power off.

Resets the display and all non-perma-

nent registers.

[On/C]

On/Clear — Turns on power. One

press clears the last entry and display.

Two presses clear all temporary registers.

[Conv]

Convert —Used with dimensional

keys to convert among dimensions.

Dimensions can only be converted with-

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

square or cubic). Also used to access

special functions when used in combi-

nation with other keys.

KEY DEFINITIONS

4 – HeavyCalc™

[Cnst]

Constant – This key is used to store a

value permanently for use as a con-

stant in repeated calculations.

[Conv] [Cnst]

Square Root —Used to find the square

root of a non-dimensional or area

value.

[M+]

Memory Add —Adds the displayed

value to the Memory total in the sum-

mation register. The Memory total is

recalled by pressing [Rcl] [M+].

[Conv] [M+]

Memory Subtract —Subtracts the dis-

played value from Memory.

[Rcl]

Recall —Recalls values stored in any

key you wish to display the value of).

[Rcl] [Rcl]

Memory Recall and Clear — Displays

and clears the value in memory.

[Conv] [Rcl]

Memory Clear — Clears Memory with-

out changing the display.

User’s Guide – 5

Dimension Keys

[Yds]

Yards —This is an entry and conver-

sion key (when used with [Conv]).

The entry can be a whole number or a

decimal number.

[Feet]

This is an entry and conversion key

(when used with [Conv]). The entry

can be in whole or decimal numbers.

This key can also be used in conjunc-

tion 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

with the [/] key for entering values in

Fractional Inch format. For example,

enter 9-1/2 inches as: 9 [Inch] 1 [/] 2.

Repeated presses of [Inch] during con-

versions, toggles between Fractional

Inch and Decimal Inch formats.

6 – HeavyCalc™

[ / ]

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 num-

ber) is not entered, then the set frac-

tional level (1/16, 1/2, etc.) is used.

[Rcl] [/] displays the current fractional

setting.

[Rcl] [x]

Imperial/Metric Mode —Selects

either Imperial or Metric defaults for

the following settings: pitch, stair riser

height, and on-center spacing.

[Cu]

Cubic —This key is used with a

dimension key (feet, inches, yards,

meters, or millimeters) to identify a

volume value. Example: 5 [Cu] [Yds].

[Sq]

Square —This key is used with a

dimension key (feet, inches, yards,

meters, or millimeters) to identify an

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

User’s Guide – 7

[m]

Meters —This is an entry and conver-

sion key used to enter decimal meters

or, when used with [Conv], to convert

to decimal meters from some other

dimensional format.

[mm]

Millimeters —This is an entry and

conversion key used to enter decimal

millimeters or, when used with [Conv],

to convert to decimal millimeters from

another dimensional format.

[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

presses of this key, after a cubic entry

or conversion, toggles among tons,

pounds and kilograms.

[Conv] [%]

Weight per Volume —Used to set the

Weight per Volume. Can be pro-

grammed as Tons per Cubic Yard,

Pounds per Cubic Yard, or Kilograms

per Cubic Meter. Default is 1.5 Tons

per Cubic Yard. To set a different

weight per volume, for example, 2

8 – HeavyCalc™

Tons per Cubic Yard, press 2 [Conv]

[%]. Value will be permanently stored.

To recall stored value, press [Rcl] [%].

Area/Volume & Angle Keys

[Length]

Enters the value for length in dimen-

sion problems (e.g., for calculating

area or volume).

[Conv] [Length]

Square-up —Computes the diagonal,

or “square-up,” based on entered

length and width.

[Width]

Enters the value for width in dimen-

sion problems (e.g., for calculating

area or volume). Also computes width

from entered values of depth and per-

cent grade or slope.

[Conv] [Width]

Percent Grade —Used to enter and

display percent grade. Also computes

percent grade using entered values for

width and depth, or slope.

[Depth]

Enters the value for depth in dimen-

sion problems (e.g., for calculating

volume). Also computes depth from

entered values of width and percent

grade or slope.

User’s Guide – 9

[Conv] [Depth]

Slope — Used to enter slope as a ratio

of run per unit rise (e.g., 4:1), or in

decimal degrees (e.g., 10°). Also com-

putes slope using entered value for

width and depth, or percent grade.

Note: Only works with width. Does not

operate in conjunction with length.

[Vol]

Volume —Computes the volume (in

cubic yards) based on entered length,

width and depth 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.

Excavation/Volume Keys

[Cut/Fill]

Used to enter or calculate the cut or fill

amount (based on entries of proposed

and existing benchmarks). A fill is dis-

played as a positive value; a cut as a neg-

ative value.
