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.
