0 – 9 Keys used for entering
and • numbers.

O Off Key — Turns all power

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

Unit 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., 6f9
i1/2). Repeated
presses during conversions
toggle between Fractional
and Decimal Feet.

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., 9i
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.

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

l Enters Length for calculation

of Area or Volume.

W Enters Width and calculates

Area, Square-up and
perimeter.

h Enters 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

Í Slope — 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

s Square-Up Key —

Calculates the “Square-up”
(diagonal) Length given
entered Length and Width
values.

d Drop 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 “con­stant 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.

F Cut/Fill Key — Used to

enter or calculate the cut or
fill amount. Based on entries
of proposed and existing
benchmarks. A fill is dis­played as a positive value; a
cut as a negative value.

POCKET REFERENCE GUIDE — 5

e Existing Key — Used to

enter or calculate an existing
benchmark, Grade or value.

p Proposed Key — Used to

enter or calculate a proposed
benchmark, Grade or value.

b Bank Volume Key —

Enters or calculates the
Volume for bank fill material.
Bank fill is material in an
untouched, pristine state.

ç Compacted Volume Key —

Enters or calculates the
Volume for compacted fill
material. Compacted fill is
material that has been com­pacted.

Çç Percent Shrink (%Shrink)

— Enters or recalls percent
shrink factor for converting
between bank and com­pacted fill Volumes. Default
is 5%.

L Loose 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 con­verting between bank and
loose Volumes. Default is
10%.

ENTERING DIMENSIONS

Linear Dimensions

When entering Feet-Inch values, enter
dimensions from largest to smallest — Feet
before Inches, Inches before Fractions.
Enter Fractions by entering the numerator
(top number), pressing / (Fraction Bar
key) and then the denominator (bottom
number).

Note: If a denominator is not entered, the frac­tional setting value is used.
