Recall Key

— Used with

other keys to

recall

stored

values and settings.

Memory Key

— Adds the displayed value to Memory. Clears when the calculator is shut off.

Ç µ

Memory Minus (M–)

— Subtracts the displayed value from Memory.

Ç ®

Memory Clear

— Clears Memory without changing current display.

® ®

Memory Clear

— Clears Memory and displays Memory Total.

Dimension Keys

Yards Key

— Enters or

converts to

Yards

Feet Key

— Enters or con-

verts to

Feet

as whole or decimal numbers. Also used with the i and / keys for entering Feet-Inch values (e.g., 6 f 9 i 1 / 2). Repeated presses during conversions toggle between Fractional and Decimal Feet.

POCKET REFERENCE GUIDE — 3

Inch Key

— Enters or con-

verts to

Inches

. Entry can be whole or decimal numbers. Also used with the / key for entering fractional inch values (e.g., 9 i 1 / 2). Repeated presses during conversions toggle between Fractional and Decimal Inches.

Fraction Bar Key

— Used

to enter

Fractions

. Fractions can be entered as proper (1/2, 1/8, 1/16) or improper (3/2, 9/8). If the denominator (bottom) is not entered, the calculator's fractional accuracy setting is automatically used.

Meters Key

— Enters or

converts to

Meters

Centimeters Key

— Enters

or converts to

Centimeters

Millimeters Key

— Enters

or converts to

Millimeters

Board Feet Key

— Enters or converts Cubic values to Board Feet. One Board Foot is equal to 144 Cubic Inches.

POCKET REFERENCE GUIDE — 4

Weight Key

— Enters or converts (a volume value) to

Tons, Pounds, Metric

Tons

Kilograms

. Repeated presses will cycle through these units.

Arc/Circle Keys

Circle Key

— Calculates Circle Area and Circumference based on entered Diameter.

Ç C

Arc

— Calculates Arc Length or Degree based on entered Diameter and Arc Degree or Length (e.g., if Arc Degree is entered, it will calculate Arc Length, and vice versa).

Right Triangle/Roof Framing Keys

Pitch Key

— This key is used to enter or calculate the Pitch (Slope) of a roof (or Right Triangle). Pitch is the amount of “Rise” over 12 Inches of “Run.” Pitch may be entered as:

POCKET REFERENCE GUIDE — 5

a Dimension 9 i p an Angle 3 0 p a Ratio 0 • 7 5 Ç p a Percentage 7 5 % p

A Pitch entry will remain in permanent storage until revised or reset. Asolution will be replaced by its entered value once the calculator is cleared.

Ç p Enters Pitch Ratio (e.g., •

5 8 3 Ç p).

Rise Key

— Enters or calculates the Rise or vertical leg (height) of a Right Triangle.

Run Key

— Enters or calculates the Run or horizontal leg (base) of a Right Triangle.

Diagonal Key

— Enters or calculates the common or Diagonal leg (Hypotenuse) of a Right Triangle. Typical applications are “squaring” slabs or finding common rafter lengths.

Hip/Valley Key

— Calculates length of the Regular or Irregular Hip/ Valley rafter.

POCKET REFERENCE GUIDE — 6

Ç H

Irregular Pitch

— Enters

Irregular

Pitch used to calculate lengths of the Irregular Hip/Valley and Jack rafters.

Jack Key

— Calculates

Jack rafter lengths on the

Regular

-pitched roof side.

Ç j

Irregular Jack

— Calculates

Jack rafter lengths on the

Irregular

-pitched roof side.

∑

Rake-Wall Key

— Finds the stud sizes based on entered Right Triangle values and the stored OnCenter spacing. If a dimensional value is entered before pressing ∑, that value is considered the base and will be added to the stud lengths.
