. 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.

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

Slope

— Enters or calculates a slope ratio or slope angle. Calculates based on entered Width and Height (Depth).

Ç Í

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

Square-Up Key

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

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., 8 y y y S ¬). The default size is 8 cubic Yards.

Cut/Fill Key

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

POCKET REFERENCE GUIDE — 5

Existing Key

— Used to enter or calculate an existing benchmark, Grade or value.

Proposed Key

— Used to enter or calculate a proposed benchmark, Grade or value.

Bank Volume Key

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

Compacted Volume Key

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

Ç ç

Percent Shrink (%Shrink)

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

Loose Volume Key

— Enters or calculates the Volume for loose fill material. Loose fill is material that has been disturbed or excavated.

Ç L

Percent Swell (%Swell)

— Enters or recalls the percent swell factor used for converting between bank and loose Volumes. Default is 10%.
