KEY DEFINITIONS

Basic Function Keys

+-x Arithmetic operation keys.

÷=

%Four-function (+, –, x, ÷)

percent key.

0– 9Keys used for entering

and •numbers.

OOff Key — Turns all power

off, clearing all non-perma-

nent registers.

oOn/Clear Key — Turns on

power. Pressing once clears

the display. Pressing twice

clears all temporary values.

ÇConvert Key — Used with

the dimensional keys to

convert between dimen-

sions or with other keys to

access special functions.

SStore Key — Used for stor-

ing values.

®Recall Key — Recalls

stored values.

GETTING STARTED

POCKET REFERENCE GUIDE — 2

Unit Keys

yYards Key — Enters or

converts to Yards.

fFeet Key — Enters or con-

verts to Feet as whole or

decimal numbers. Also

used with the iand /

keys for entering Feet-Inch

values (e.g., 6f9

i1/2). Repeated

presses during conversions

toggle between Fractional

and Decimal Feet.

iInch Key — Enters or con-

verts to Inches. Entry can

be whole or decimal num-

bers. Also used with the /

key for entering fractional

Inch values (e.g., 9i

1/2). Repeated press-

es during conversions tog-

gle 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 denomina-

tor (bottom) is not entered,

the calculator's fractional

accuracy setting is auto-

matically used.

mMeters Key — Enters or

converts to Meters.

POCKET REFERENCE GUIDE — 3

Ç7 Centimeters (cm) — Enters

or converts to Centimeters.

Ç9 Millimeters (mm) — Enters

or converts to Millimeters.

Ç2 Acres (Acre) — Enters or

converts to Acres.

Length, Width and Height Keys

lEnters Length for calculation

of Area or Volume.

WEnters Width and calculates

Area, Square-up and

perimeter.

hEnters Height and calculates

Volume, wall Area and total

room Area. Calculates Height

(Depth) based on entered

Width and Slope or Percent

Grade. This is a permanent

entry; stored value holds

when turned off.

Construction Project Keys

ÍSlope — Enters or calcu-

lates a slope ratio or slope

angle. Calculates based on

entered Width and Height

(Depth).

ÇÍ Percent Grade (%Grade) —

Used to enter or solve Percent

Grade. Calculates Percent

Grade based on entered

Width and Height (Depth) or

Slope.

POCKET REFERENCE GUIDE — 4

sSquare-Up Key —

Calculates the “Square-up”

(diagonal) Length given

entered Length and Width

values.

dDrop Key — Calculates

total drop (or fall) over an

entered Length given

entered percentage drop,

Inch per Foot drop, or

degrees of drop. Continued

presses will act as a “con-

stant add,” for displaying

successive drops.

Excavation/Volume Keys

¬Loads Key — Calculates

number of loads for a given

Volume or Length, Width,

and Height (Depth) values

and stored load size.

S¬ Load Size — Stores load

size. Load size must be

entered as a cubic value

(e.g., 8yyy

S¬). The default size

is 8 cubic Yards.

FCut/Fill Key — Used to

enter or calculate the cut or

fill amount. Based on entries

of proposed and existing

benchmarks. A fill is dis-

played as a positive value; a

cut as a negative value.

POCKET REFERENCE GUIDE — 5

eExisting Key — Used to

enter or calculate an existing

benchmark, Grade or value.

pProposed Key — Used to

enter or calculate a proposed

benchmark, Grade or value.

bBank Volume Key —

Enters or calculates the

Volume for bank fill material.

Bank fill is material in an

untouched, pristine state.

çCompacted Volume Key —

Enters or calculates the

Volume for compacted fill

material. Compacted fill is

material that has been com-

pacted.

Çç Percent Shrink (%Shrink)

— Enters or recalls percent

shrink factor for converting

between bank and com-

pacted fill Volumes. Default

is 5%.

LLoose Volume Key —

Enters or calculates the

Volume for loose fill material.

Loose fill is material that has

been disturbed or excavated.

ÇL Percent Swell (%Swell) —

Enters or recalls the percent

swell factor used for con-

verting between bank and

loose Volumes. Default is

10%.

POCKET REFERENCE GUIDE — 6

Miscellaneous Functions

aBackspace Key.

Ça ( ) Square Root.

®= Paperless Tape.

ÇS Preference Settings.

Ç÷ (1/x) Reciprocal — Finds

the reciprocal of a number

(e.g., 8Ç÷0.125).

Çx Clear All — Returns all

stored values to the default

settings. (Does not affect

Preference Settings.)

Ç- (+/–) Toggle.

Ç+ Pi (π) 3.141593.

Ç• Converts between D:M:S

and decimal degrees.

Ç% x2— Squares the value in

the display.

Ç/ Exponential Notation (x10y).

Ç0 Total Cost (based on entry

of per unit cost).

S0 Weight per Volume –

Stores a new Weight per

Volume value.

Note: After entering a value and pressing S0,

continue pressing the 0digit key until you’ve

reached the desired Weight per Volume format.

To recall your setting, press ®0.
