KEY DEFINITIONS/FUNCTIONS

Basic Functions

[+] [–] [x]

[÷] [=] Arithmetic operation keys.

[%] Four-function percent key.

0 – 9 Digits used for keying-in numbers.

[ • ] Decimal point.

[Off]

Turns all power off. Resets the dis-

play and all non-permanent registers.

[On/C] Turns on power. Pressing once

clears the last entry and the dis-

play. Pressing twice in succession

clears all temporary registers.

[Conv]

Used to convert between dimen-

sions. Dimensions can only be con-

verted within the same convention

(i.e., linear, square or cubic). Also

used to access special functions.

GETTING STARTED

4—C

ONSTRUCTION

ASTER

Used to find the square root of a

number.

[Conv]

x2 — Finds the square of the dis-

played value.

[M+] Memory Plus — Stores the dis-

played number in the semi-perma-

nent Memory. Also adds the

displayed number to any previous-

ly stored value in Memory. The

total stored in Memory is recalled

by pressing [Rcl] prior to [M+].

[Conv]

[M+] Memory Minus (M–) — Subtracts

the displayed value from Memory.

[Rcl] Recall — Recalls values stored in

any register (i.e., press [Rcl] and

then the key you wish to display

the value of). [Rcl] [M+] displays

Memory content.

******************************************

[Rcl] [x] Imperial/Metric Mode — Selects

either Imperial or Metric defaults

for the following settings: pitch,

stair riser height, and on-center spac-

ing for jack rafters and rake-walls.

Note: This is a permanent setting

cleared only by removing batteries

or manually resetting.

******************************************

[Conv]

[Rcl] Memory Clear — Clears the

Memory without changing the

current display.

Dimension Keys

[Yds] Yards — This is an entry and con-

version key (when used with

[Conv]).

[Feet] Feet — This is an entry and con-

version key (when used with

[Conv]). This key can also be used

in conjunction with the [Inch] and

[/] keys for entering in Feet-Inch-

Fractions.

6—C

ONSTRUCTION

ASTER

[Inch] Inches — This is an entry and con-

version key (when used with

[Conv]). This key can also be used

in conjunction with the [/] key for

entering values in Fractional Inch

format.

[/] Fraction Bar — This key is used to

enter fractions. For example, to

enter 1/2, the key sequence would

be: 1 [/] 2.

[Cu] Cubic — This key is used with a

dimension key to identify a value

as being a volume.

Example: 5 [Cu] [Yds].

[Sq] Square — This key is used with a

dimension key to identify a value

as being an area.

Example: 10 [Sq] [Meters].

[m] Meters — This is an entry and con-

version key used to enter decimal

meters or to convert decimal

meters.

[cm] Centimeters — Entry and conver-

sion key for centimeters. Operates

the same as metric.

7 — User’s Guide

[mm] Millimeters — Entry and conver-

sion key for millimeters. Operates

the same as metric.

[Bd Ft] Board Feet — This key is used to

enter or convert cubic values to

board feet (using [Conv]). One

board foot is equal to 144 cubic

inches (1 inch x 1 foot x 1 foot).

[Weight] Weight — This key is used to con-

vert volume to a weight value using

the [Conv] key and the stored

Weight per Volume factor (see

below). Press repeatedly to toggle

between tons, pounds and kilo-

grams.

[Conv]

[%]

Weight per Volume — Used to set the

Weight per Volume factor. Factor

can be entered as Kilograms per

Cubic Meter, Tons per Cubic Yard,

or Pounds per Cubic Yard. To set a

different weight per volume, i.e.,

2150 Kilograms per Cubic Meter,

press 2150 [Conv] [%] [%] [%].

Right Triangle/Rafter Keys

[Pitch] Pitch — This key is used to per-

manently enter or calculate the

pitch (slope) of a roof (or right tri-

angle). Pitch may be entered as an

inch format (9 [Inch] [Pitch]), or

as an angle in degrees (i.e., 30

[Pitch] for 30°), or also as a unit-

less ratio (0.75 [Conv] [Pitch]).

[Rise] Rise — This key enters or calcu-

lates the rise or vertical leg of a

right triangle.

[Run] Run — This key enters or calcu-

lates the run or horizontal leg (or

base) of a right triangle.

9 — User’s Guide

[Diag] Diagonal — This key enters or

calculates the diagonal leg or

hypotenuse of a right triangle.

[Conv]

[Diag] Rake-Wall — This function finds

the decreasing stud sizes in a rake-

wall based on computed or entered

values for pitch, rise and/or run.

Repeated presses of [Diag] will dis-

play the descending stud sizes from

longest to shortest.

The on-center spacing of a rake-

wall can be permanently stored by

entering a dimension prior to solv-

ing for stud sizes (for example, 750

[mm] [Conv] [Diag]

will store 750

millimeters as the on-center spac-

ing). Default on-center spacing is

600 millimeters in Metric Mode

(16 inches in English Mode).

[Hip/V] Hip/Valley — Finds the regular (45°)

hip/valley rafter length based on

entered or solved values for Pitch,

Rise, Run and/or Diagonal. If this

key is pressed after an irregular pitch

entry (see below), the length of the

ASTER

irregular (non-45°) hip/valley rafter

is displayed. Answers will show an

“I” on the display to indicate if it’s

an irregular.

[Conv]

[Hip/V] Irregular Pitch — Stores the irreg-

ular pitch or slope value for calcu-

lating lengths of the irregular

hip/valley and irregular jack rafters.

For instance, to enter a 38° irregu-

lar pitch or slope, press 38 [Conv]

[Hip/V] (or, to enter a ten inch

irregular pitch, enter 10 [Inch]

[Conv] [Hip/Valley]). To recall

the irregular pitch, press [Rcl]

[Conv] [Hip/Valley]. An irregular

pitch is designated with an “I”.
