the second value and then the equals

sign (=).

3 [+] 2 [=] 5

3 [–] 2 [=] 1

3 [x] 2 [=] 6

This feature also makes the calculator

simple to use for dimensional math, as

shown in the following examples:

Adding Dimensions

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

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

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

Percentage Calculations

The Percent [%] key is used to find a

percent 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

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

memory until revised or reset.

The fractional level can be revised by

using the keystrokes below:

Keystroke Fraction Setting

[Conv] 1 1⁄ 16

[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

anything other than 1⁄16 normal mode, a

star (

★

) will appear in the bottom left of the

display during power up to indicate a spe-

cial fractional setting has been stored with-

in. The fractional setting can be displayed

at any time by pressing [Rcl] [/].

User’s Guide – 15

4015-UG-B 4/4/03 12:29 PM Page 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 temporar-

ily revised to the level of accuracy of the

entered value.

Fixed Fractional Mode

In the

Fixed Mode

(

[Conv] 9

), fractional

results are displayed in the set fractional

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 accura-

cy level is set. Pressing

[Conv] [/]

again

will turn the flashing denominator 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 display

will look similar to this:

The display shows the entered or calcu-

lated value (12 Inch), sequence number

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

it is “+”) for each entry. As you scroll

through the entries, you will see the des-

ignators

TTL

and

SUB

. “

SUB

” indicates a

subtotal. “

TTL

” indicates the final total (all

subtotals combined).

How to Use the Tape

USING THE MEASURE

MASTER CLASSIC

Entering Dimensions and Units

When entering feet-inch dimensional val-

ues, you must enter the largest dimen-

sion first — feet before inches, inches

before fractions. To enter fractions of an

inch, enter the numerator (value above

the line), press [/] (fraction 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 decimal

numbers. You cannot enter combinations

of units (for example, you cannot enter 12

meters 6 centimeters 4 millimeters).
