Adding Dimensions

Add 7 feet 3-1/2 inches to 11 feet 4 inches:

7 [Feet] 3 [Inch] 1[/] 2 [+]

11 [Feet] 4 [Inch] [=] 18 FT 7-1/2 IN

Add 11 inches to 2 feet 1 inch:

11 [Inch] [+] 2 [Feet] 1 [Inch] [=] 36 IN

Add 2 feet 1 inch to 11 inches:

2 [Feet] 1 [Inch] [+]

11 [Inch] [=] 3 FT 0 IN

Note: The format of the first value you enter

determines the format of the answer.

However, with the [Conv] key you can

change to any format you want, provided

that you maintain convention.

Subtracting Dimensions

Subtract 3 feet from 11 feet 7-1/2 inches:

11 [Feet] 7 [Inch] 1 [/] 2

[–] 3 [Feet] =] 8 FT 7-1/2 IN

Subtract 32 inches from 81 inches:

81 [Inch] [–] 32 [Inch] [=] 49 IN

Multiplying Dimensions

Multiply 5 feet 3 inches by 11 feet 6-1/2 inches:

5 [Feet] 3 [Inch] [x]

11 [Feet] 6 [Inch] 1 [/] 2 [=] 60.59375 SQ FT

User’s Guide – 11

Multiply 2 feet 7 inches by 10 :

2 [Feet] 7 [Inch] [x] 10 [=] 25 FT 10 IN

Dividing Dimensions

Divide 30 feet 4 inches by 7 inches:

30 [Feet] 4 [Inch] [÷] 7 [Inch] [=] 52

Divide 20 feet 3 inches by 9:

20 [Feet] 3 [Inch] [÷] 9 [=] 2 FT 3 IN

Percentage Calculations

The Percent [%] key is used to find a per-

cent of a number or for working add-on,

discount or division percentages. It can be

used with any type of number, any

dimension (feet, inch, millimeter, etc) and

convention (non-dimensioned, linear,

square or cubic).

Find 18% of 500 feet:

500 [Feet] [x] 18 [%] 90 FT 0 IN

Add 10% for waste to 137 square feet:

137 [Sq] [Feet] [+] 10 [%] 150.7 SQ FT

Take 20% away from 552 feet 6 inches:

552 [Feet] 6 [Inch] [–] 20 [%] 442 FT 0 IN

Recall & clear [Rcl] [Rcl] 50.

The memory function can also be used

with dimensional units, as long as they

are of the same convention (all linear,

square or cubic). The calculator will

display the word “ERROR” if you try to

enter numbers of different conventions.

Fractional Settings

When you first receive your calculator

it is set to its default state. When in this

state, fractional values are rounded to

the nearest 1/16 of an inch. However,

you may program your preference for

six different accuracy levels and two

different modes (Normal and Fixed), all

of which remain in permanent memo-

ry until revised or reset.

The fractional level can be revised by

using the keystrokes below:

Keystroke Fraction Setting

[Conv] 1 1/1

6

[Conv] 2 1/2

[Conv] 3 1/32

[Conv] 4 1/4

[Conv] 6 1/64

[Conv] 8 1/8

Note: Whenever the calculator is set to any-

thing other than 1/16 normal mode, a star

(

★

) will appear in the bottom left of the dis-

play during power up to indicate a special

fractional setting has been stored within.

The fractional setting can be displayed at

any time by pressing [Rcl] [/].

User’s Guide – 15

Normal Fractional Mode

The default, Normal Mode ([Conv] 7),

reduces a fraction to its lowest common

denominator (for example, 8/16 reduces

to 1/2). If a fraction is entered having a

higher fractional accuracy than the cur-

rent setting, the setting will be tem-

porarily revised to the level of accuracy

of the entered value.

Fixed Fractional Mode

In the Fixed Mode ([Conv] 9), fraction-

al results are displayed in the set frac-

tional value, not reduced. Entries of

higher accuracy values will be rounded

to the nearest fraction of the accuracy

setting (for example, for a fraction level

setting of 1/16, an entry of 5 [/] 32 [=]

will result in a display of 3/16).

Flashing Denominator

Your calculator can be set to flash the

denominator (bottom) when entering

fractions by pressing [Conv] [/ ]. In this

way, you can see what fractional accu-

racy level is set. Pressing [Conv] [/]

again will turn the flashing denomina-

tor off. This is a permanent setting that

will remain until revised or reset.

“Paperless Tape” Feature

The “Paperless Tape” feature allows the

user to display the last 20 entries. While

in the Paperless Tape mode, your dis-

play will look similar to this:

The display shows the entered or cal-

culated value (12 Inch), sequence num-

ber (04), and the math operator (in this

case it is “+”) for each entry.

As you scroll through the entries, you will

see the designators TTL and SUB. “SUB”

indicates a subtotal. “TTL” indicates the

final total (all subtotals combined).

How to Use the Tape

Steps/Keystrokes Display

1. Clear calculator and enter a string of

numbers:

[On/C] [On/C] 0.

4 [Feet] [+] 4 FEET 0 INCH

5 [Feet] [+] 9 FEET 0 INCH

6 [Feet] [+] 15 FEET 0 INCH

†Note: At this point, you can press any

key twice (except [Off], [+] or [–]) to exit the

tape feature.

When you press a key to exit the tape,

the total value displays. The next key

press begins a new tape function.

Clearing the Paperless Tape

The paperless tape is cleared:

1) when you press

[On/C] [On/C] (clear);

2) when you press

[Conv] [x] (all clear);

3) when you turn the unit off.

User’s Guide – 19

Entering Dimensions & Units

When entering feet-inch dimensional

values, you must enter the largest

dimension first — feet before inches,

inches before fractions. To enter frac-

tions of an inch, enter the numerator

(value above the line), press [/] (frac-

tion bar key) and then enter the

denominator (value below the line).

numerator 3

fraction bar —

denominator 16

For all other units of measurement, you

can only enter whole numbers or dec-

imal numbers. You cannot enter com-

binations of units (for example, you

cannot enter 12 meters 6 centimeters 4

millimeters).
