off, clearing all non-perma­nent registers.

o On/Clear Key — Turns on

power. Pressing once clears
the display. Pressing twice
clears all temporary values.

Ç Convert Key — Used with

the dimensional keys to
convert between dimen­sions or with other keys to
access special functions.

find the Square Root of a
non-dimensional or area
value.

Ç √ x2Function — Finds the

Square of a linear or non­dimensional value.

GETTING STARTED

OCKET REFERENCE GUIDE — 2

® Recall Key — Used with

other keys to recall stored
values and settings.

μ 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

y Yards Key — Enters or

converts to Yards.

f 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.

P

OCKET REFERENCE GUIDE — 3

i 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.

m Meters Key — Enters or

converts to Meters.

c Centimeters Key — Enters

or converts to Centimeters.

M Millimeters Key — Enters

or converts to Millimeters.

b Board Feet Key — Enters

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

P

OCKET REFERENCE GUIDE — 4

w Weight Key — Enters or

converts (a volume value)
to Tons, Pounds, Metric
Tons or Kilograms.
Repeated presses will cycle
through these units.

Arc/Circle Keys

C 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

p 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:

P

OCKET 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. A solution
will be replaced by its
entered value once the
calculator is cleared.

Ç p Enters Pitch Ratio (e.g., •

5 8 3 Ç p).

r Rise Key — Enters or cal-

culates the Rise or vertical
leg (height) of a Right
Triangle.

R Run Key — Enters or cal-

culates the Run or horizon­tal leg (base) of a Right
Triangle.

d 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.

H Hip/Valley Key —

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

P

OCKET REFERENCE GUIDE — 6

Ç H Irregular Pitch — Enters

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

j 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.

Stair Layout Key

s Stair Key — Given Rise

and/or Run and entered/
stored variables, calculates
or displays:

1 Riser Height
2 Number of Risers
3 Riser Overage/

Underage
4 Tread Width
5 Number of Treads

• 10” Desired Tread Width

P

OCKET REFERENCE GUIDE — 8

Stair Settings

You may set “desired Riser height” and
“desired Tread width” to any value by
using the following keys:

Ç 7 Riser Height — Stores a

desired Riser height other
than 7-1/2” (default). For
example, enter 8 Inches:

8 i Ç 7.

Ç 9 Tread Width — Stores a

desired Tread width other
than 10” (default). For
example, enter 12 Inches:
1 2 i Ç 9.

Miscellaneous Functions

B Backspace Key — Used

to delete entries one key­stroke at a time (unlike the
o function, which deletes
the entire entry).

Ç ÷ 1/x — Finds the reciprocal

of a number (e.g., 8 Ç

÷ 0.125).

Ç x Clear All — Returns all

stored values to the default
settings. (Does not affect
Preference Settings.)

Ç – (+/–) Toggle
Ç + Pi (π) 3.141593

P

OCKET REFERENCE GUIDE — 9

Ç √ x2— Squares the value in

the display.

√ Square Root Key — Used

to find the Square Root of a
non-dimensional or area
value.

Ç • Total Cost — Based on

entry of per unit cost.

Ç 0 Store Weight per Volume

— Stores a new Weight per
Volume value as listed

below:

Note: After entering a value
and pressing Ç 0, continue
pressing the 0 digit key until
you’ve reached the desired
Weight per Volume format. To
recall your setting, press ® 0.

• Ton Por YD CUB

• LB Por YD CUB

• LB Por PIES CUB

• MET Ton Por M CUB

• kG Por M CUB
This value is stored until

you change it or perform a

Clear All (Ç x).

Ç 5 On-Center Spacing (o.c.)

— Stores a new on-center
spacing (e.g., 2 4 i
Ç5). The value is used
for jack and rake wall stud
calculations. Default is 16”.
