GETTING STARTED

KEY DEFINITIONS

Basic Operation Keys

[On/C] —On/Clear Key

Turns power on. Pressing once clears the display. Pressing twice

clears any previously entered value.

[Conv] [On/C] —Off

Turns all power off.

[Rcl] —Recall

Recalls stored values (e.g., [Rcl] [Recipe # Servings]).

[0] –[9] [00] and [ •• ]

Digits used for keying in numbers. The [00] saves keystrokes when

entering ’00 values (e.g., 1 [00] for “100”).

[%] —Percent

Four-function percent.

[+] [–] [x] [÷] [=]

Arithmetic operation keys.

[Conv] —Convert

Converts to various unit keys (e.g., cooking units, temperature).

[Conv] [+] —(M+) Memory

Adds displayed value to the standard, cumulative Memory. (To sub-

tract from Memory, press a value, then [Conv] [–] [Conv] [+]).

[Conv] [Rcl] —Recall Memory

[Conv] [Rcl] [Rcl] —Clear Memory

[Conv] [–] —Change Sign (+/–)

Changes the sign of the displayed value from plus to minus and vice

versa.

4—KitchenCalc Pro—Master Chef’s Edition

[Conv] [x] —Clear Recipe Memory

Clears the values entered into the # of Servings and Portion Size

keys, as these values are stored in memory (i.e., remain stored even

after you turn your calculator off).

[Conv] [x] [x] —Clear All

Clears all stored values, including memory, serving and portion siz-

ing.

Cooking Unit Keys

[lb] —Pound

Enters or converts to pounds.

[dry oz] —Dry Ounce

Enters or converts to dry ounces.

[fl oz] —Fluid Ounce

Enters or converts to fluid ounces.

[cup] —Cup

Enters or converts to cups.

[tbsp] —Tablespoon

Enters or converts to tablespoons.

[tsp] —Teaspoon

Enters or converts to teaspoons.

[ / ] —Fraction Bar Key

Used to enter fractions (e.g., 1 [/] 3 [cup]).

[Conv] [ / ] —Rnd +/-(Remainder)

Displays the fractional remainder (if applicable), due to “kitchen-

friendly” values, or calculator rounding. This is an optional calculation

and should be used if you want more precise measurements. When

the calculator has rounded by more than 5%, the display will read

^Rnd (it has rounded up) or íRnd (rounded down). When this occurs,

press [Conv] [/] to display the remainder. A plus (+) tells you to add

the additional measurement, and a (-) tells you to subtract—e.g.,

[Conv] [/] = + 0-1/2 TSP means you should add an additional 1/2

teaspoons of the ingredient.

User's Guide —5

Note: If you want to minimize rounding altogether, convert to the next smallest cooking

unit (e.g., if it reads tablespoons, convert to teaspoons).

[Timer 1] / [Timer 2] —Built-in Cooking Timers

Accesses the dual count up/count down timers.

2nd Functions—Additional Conversion Units

Recipe Scaling Keys

Use the keys below to “scale” recipes (when you’re cooking or bak-

ing for less or more than the recipe’s stated serving size, and have

to calculate adjusted ingredient quantities). Your calculator quickly

converts recipe ingredients to their proper proportions, so you can

cook or bake precisely and avoid measurement errors.

First, find the recipe’s stated number of servings or yield, and then

determine how many servings you need to make (if other than the

stated serving size). Use the keys below to enter the “stated” and

“desired” serving sizes (and/or portion sizes), enter each ingredient

quantity and press [Adjust Recipe] to convert each ingredient to its

new, adjusted quantity.

Note: You may prefer to write the new quantities on a piece of paper, or note them

next to the recipe’s ingredients, or simply measure new ingredient amounts as you

go.

[Recipe # Servings] —Recipe’s Number of

Servings

Enters the recipe’s stated number of servings.

[Actual # Servings] —Actual Number of Servings

Enters your desired number of servings.

[Conv] [Recipe # Servings] —Recipe’s Portion Size

Enters the recipe’s stated per person portion size.

[Conv] [Actual # Servings] —Actual Portion Size

Enters your desired per person portion size.

[Adjust Recipe] —Recipe Adjust

Calculates adjusted ingredient quantities based on entered # of Serv-

ings and/or Portion Size.

[Rcl] [Adjust Recipe] —Recipe Scale Factor

Displays the ratio used for adjusting ingredients.

Note: Values entered in Recipe Scaling Keys are stored permanently, so use [Conv]

[x] to clear them prior to entering a new problem. Also, to review stored values, press

[Rcl] and the applicable key. For example, to review your stored Recipe’s Number of

Servings, press [Rcl] [Recipe # Servings]. To review your stored Recipe’s Portion Size,

press [Rcl] [Conv] [Recipe # Servings]).

ENTERING COOKING UNITS (WHOLE AND FRACTIONS)

Enter whole cooking units by entering: 1) the quantity and 2) press-

ing the appropriate cooking unit key. For example:

Enter 3 tablespoons:

Keystroke Display

3 [tbsp] 3 TBSP

Enter cooking units with fractions (e.g., 1/3 cup) by pressing the

fraction [/] key. For example:

Enter 2-1/3 cups:

Keystroke Display

2 1 [/] 3 [cup] 2-1/3 CUP

You can also enter the whole unit first, then the cooking unit key,

then the fraction. For example:

Enter 2-1/3 cups:

Keystroke Display

2 [cup] 1 [/] 3 2-1/3 CUP

BASIC MATH WITH COOKING UNITS

You can perform basic math with cooking units. For example:

What is 1-3/4 cups + 2-1/3 cups?

Keystroke Display

1 3 [/] 4 [cup] [+] 2 1 [/] 3 [cup] [=] 4-1/8 CUP

What is 1/8 tsp x 6?

Keystroke Display

1 [/] 8 [tsp] [x] [6] [=] 0-3/4 TSP

(Cont’d)

8—KitchenCalc Pro—Master Chef’s Edition

(Cont’d)

Find 2 tbsp ÷ 3:

Keystroke Display

2 [tbsp] [÷] [3] [=] 0-2/3 TBSP

Note: The results of math calculations will be shown as actual, not rounded, “kitchen-

fractions”(see following section for more details).

DISPLAYING ACTUAL FRACTIONS VS. “KITCHEN FRACTIONS”

A unique feature of your calculator is that it will display both actual

fractions and “kitchen fractions” during conversions or recipe scal-

ing calculations. That is, if the answer is 3/4 TBSP, it knows there is

no “3/4” of a tablespoon,or measuring spoon,available to measure

with; instead, it will show the rounded answer (i.e., 1 TBSP). For

more precise measuring, you can then press the [Conv] [/] keys to

display the remainder amount to add or subtract, or simply convert

the value to the next lowest cooking unit (e.g., TSP), to avoid the

remainder altogether.

“Kitchen Fractions,” or whole units or fractions displayed in recipe

scaling calculations or conversions, include:

AVAILABLE KITCHEN FRACTIONS

Tablespoon Teaspoon Cup

1 TBSP 1 TSP 1 CUP

1/2 TBSP 7/8 TSP 7/8 CUP

3/4 TSP 3/4 CUP

5/8 TSP 2/3 CUP

1/2 TSP 1/2 CUP

3/8 TSP 1/3 CUP

1/4 TSP 1/4 CUP

1/8 TSP 1/8 CUP

Note: 1/3 TSP, 2/3 TSP, 1/8 TBSP, 1/4 TBSP, 1/3 TBSP, 3/8 TBSP, 5/8 TBSP,

2/3 TBSP, 3/4 TBSP, 7/8 TBSP, 3/8 CUP and 5/8 CUP are not available kitchen

fractions.

User's Guide —9

If you do not want to view “kitchen” values, you can display actual

values by pressing the cooking unit key again. Important Note: The

calculator will tell you when an actual value is displayed by display-

ing the word “Actual.”

See examples below:

Basic Math—Displaying Actual vs. Kitchen Fractions

Find 5-1/2 tbsp [÷] 2:

Keystroke Display

5 1 [/] 2 [tbsp] [÷] [2] [=] 2-3/4 TBSP (Actual Fraction)

[tbsp] 3 TBSP (Kitchen Fraction)*

[tbsp] 2.75 TBSP (Actual Decimal Value)

*Here, the calculator rounded up to a measuring spoon value you can actually meas-

ure with (as there are no “3/4 tbsp” size measuring spoons).

Conversions—Displaying Actual vs. Kitchen Fractions

Convert 2-3/4 tbsp to a “kitchen fraction,” actual decimal value, then

return to the entered value:

Keystroke Display

2 3 [/] 4 [tbsp] 2-3/4 TBSP

[Conv] [tbsp] 3 TBSP (Kitchen Fraction)*

[tbsp] 2.75 TBSP (Actual Decimal Value)

[tbsp] 2-3/4 TBSP (Actual Fraction)

*Here, the calculator rounded up to a unit you can actually measure with.

Recipe Scaling—Actual vs. Kitchen Fractions Displayed

When performing Recipe Scaling using the [Adjust Recipe] key and

the answer is in a fractional format that does not support existing

measuring spoons or cups (see “Available Kitchen Fractions” on pre-

vious page),the “kitchen fraction” value will be displayed first. A sec-

ond press of the [Adjust Recipe] key will display the actual fraction

value. A third press will display the actual decimal value.
