f
Feet 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., 6 f 9 i
1 / 2). Repeated press-
es during conversions tog-
gle between Decimal Feet
and Feet-Inch-Fractions.
i
Inch 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., 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 denomina-
tor (bottom) is not entered,
the calculator's fractional
accuracy setting is automat-
ically used.

used with a dimension key
(Feet, Inches, Yards,
Meters, etc.) to identify a
value as being a volume.
Example:
5 C y
S
Square Key
— This key is
used with a dimension key
(Feet, Inches, Yards,
Meters, etc.) to identify a
value as being an area.
Example:
1 0 S f

4320PRG-E-A 6/16/04 7:53 AM Page 7
POCKET REFERENCE GUIDE — 8
Ç d
Slope
— Used to enter
Slope as a ratio of Run per
Unit Rise (e.g., 4:1), or in
Decimal Degrees (e.g.,
10°). Also calculates Slope
using entered value for
Width and Depth or Percent
Grade.
v
Volume Key
— Computes
the Volume (Length x Width
x Depth) in Cubic Yards
based on entered Length,
Width and Height values. A
second press will display
the area (in Square Feet)
based on entered Length
and Width. Successive
presses will toggle the dis-
play between the calculated
Area and Volume.
Ç v
Area
—Computes the area
in Square Feet based on
entered Length and Width.
Excavation/Volume Keys
FUsed 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.

—
Enters or calculates the vol-
ume 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.
Ç ç
% Shrink
— Enters or
recalls percent shrink factor
for converting between bank
and compacted fill volumes.
L
Loose Volume Key
—
Enters or calculates the vol-
ume for loose fill material.
Loose fill is material that
has been disturbed or
excavated.
Ç L
% Swell
— Enters or recalls
the percent swell factor used
for converting between
bank and loose volumes.
