Arithmetic operation keys. |
÷ = |
|
0– 9 |
Keys used for entering |
and • |
numbers. |
%Percent Key — Four-func - tion (+, –, x, ÷) percent key.
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 dimensions or with other keys to access special functions.
Square Root Key — Used to find the Square Root of a non-dimensional or area value.
Çx2 Function — Finds the Square of a linear or nondimensional value.
POCKET REFERENCE GUIDE — 1
®Recall Key — Used with other keys to recall stored values and settings.
µMemory Key — Adds the displayed value to Memory. Clears when the calculator is shut off.
ǵ Memory Minus (M–) —
Subtracts the displayed value from Memory.
Ç® Memory Clear — Clears Memory without changing current display.
®® Memory Clear — Clears Memory and displays Memory Total.
Dimension 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., 6 f9 i 1 /2). Repeated presses during conversions toggle between Fractional and Decimal Feet.
POCKET REFERENCE GUIDE — 2
iInch 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., 9 i1 /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.
mMeters Key — Enters or converts to Meters.
cCentimeters Key — Enters or converts to Centimeters.
MMillimeters Key — Enters or converts to Millimeters.
bBoard Feet Key — Enters or converts Cubic values to
Board Feet. One Board Foot is equal to 144 Cubic Inches.
POCKET REFERENCE GUIDE — 3
wWeight Key — Enters or converts (a volume value) to Tons, Pounds, Metric Tons or Kilograms. Repeated presses will cycle through these units.
Arc/Circle Keys
CCircle Key — Calculates Circle Area and Circumference based on entered Diameter.
ÇC Arc — Calculates Arc Length or Degree based on entered Diameter and Arc Degree or Length (e.g., if Arc Degree is entered, it will calculate Arc Length, and vice versa).
Right Triangle/Roof Framing Keys
pPitch Key — This key is used to enter or calculate the Pitch (Slope) of a roof (or Right Triangle). Pitch is the amount of “Rise” over 12 Inches of “Run.” Pitch may be entered as:
POCKET REFERENCE GUIDE — 4
a Dimension |
9ip |
an Angle |
30p |
a Ratio 0•75Çp |
|
a Percentage |
75%p |
A Pitch entry will remain in permanent storage until revised or reset. A solution will be replaced by its entered value once the calculator is cleared.
Çp Enters Pitch Ratio (e.g., •
5 8 3 Ç p).
rRise Key — Enters or cal - culates the Rise or vertical leg (height) of a Right
Triangle.
RRun Key — Enters or cal - culates the Run or horizontal leg (base) of a Right Triangle.
dDiagonal Key — Enters or calculates the common or Diagonal leg (Hypotenuse) of a Right Triangle. Typical applications are “squaring” slabs or finding common rafter lengths.
HHip/Valley Key —
Calculates length of the Regular or Irregular Hip/ Valley rafter.
POCKET REFERENCE GUIDE — 5
ÇH Irregular Pitch — Enters
Irregular Pitch used to calculate lengths of the Irregular Hip/Valley and Jack rafters.
jJack Key — Calculates Jack rafter lengths on the Regular-pitched roof side.
Çj Irregular Jack — Calculates Jack rafter lengths on the Irregular-pitched roof side.
Rake-Wall Key — Finds the stud sizes based on entered Right Triangle values and the stored OnCenter spacing. If a dimensional value is entered before pressing , that value is considered the base and will be added to the stud lengths.
POCKET REFERENCE GUIDE — 6
Stair Layout Key
sStair Key — Given Rise and/or Run and entered/ stored variables, calculates or displays:
Press Result
1 Riser Height
2 Number of Risers
3 Riser Overage/ Underage
4 Tread Width
5 Number of Treads
6 Tread Overage/ Underage
7 Stringer Length
8 Angle of Incline
9 Stored Run
10 Stored Rise
11 Stored Desired Riser Height
12 Stored Desired
Tread Width
STAIR DEFAULT VALUES
•7-1/2” Desired Riser Height
•10” Desired Tread Width
POCKET REFERENCE GUIDE — 7
Stair Settings
You may set “desired Riser height” and “desiredTread width” to any value by using the following keys:
Ç7 Riser Height — Stores a desired Riser height other than 7-1/2” (default). For example, enter 8 Inches:
8 i Ç 7.
Ç9 Tread Width — Stores a desired Tread width other than 10” (default). For example, enter 12 Inches:
1 2 i Ç 9.
Miscellaneous Functions
BBackspace Key — Used to delete entries one keystroke at a time (unlike the
ofunction, which deletes the entire entry).
Ç÷ 1/x — Finds the reciprocal of a number (e.g., 8 Ç
÷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
POCKET REFERENCE GUIDE — 8
Çx2 — Squares the value in the display.
Square Root Key — Used to find the Square Root of a non-dimensional or area value.
Ç• Total Cost — Based on entry of per unit cost.
Ç0 Store Weight per Volume
—Stores a new Weight per Volume value as listed below:
Note: After entering a value and pressing Ç 0, continue pressing the 0digit key until you’ve reached the desired Weight per Volume format. To recall your setting, press ®0.
•Ton Per CU YD
•LB Per CU YD
•LB Per CU FEET
•MET Ton Per CU M
•kG Per CU M
This value is stored until you change it or perform a
Clear All (Ç x).
Ç5 On-Center Spacing (o.c.)
—Stores a new on-center spacing (e.g., 2 4 i Ç5). The value is used for jack and rake wall stud calculations. Default is 16”.
POCKET REFERENCE GUIDE — 9
®= Paperless Tape – Useful for checking figures, as it scrolls through your past 20 entries or calculations. Press ® =to access Paperless Tape mode. Press +or –to scroll forward or backward. Press = to exit mode and continue with a new entry or calculation. See example below.
PAPERLESS TAPE EXAMPLE
Add 6 Feet, 5 Feet and 4 Feet, then access the paperless tape mode and scroll back through your entries. Then, back up one entry, exit the tape mode and add 10 Feet to the total.
