• imensional Math Problems

• Conversions Between Feet-Inch-Fractions, ecimal Feet,

ecimal Inches and Metric

• Problems Involving All Common Fractions – 1/2” to 1/64”

• Area/Volume Calculations

• Arc/Circle/Column/Cone Areas and Volumes

• :M:S

• Scientific Notation, Cubed Root

• Offset Calculations

• Trigonometry

• Law of Cosines

• Fan Laws 1, 2 and 3

• Velocity/Velocity Pressure Conversions

• Right Angle/Rafter Solutions

• Stair Layout (Risers/Treads), and more!

It also includes handy construction math and material estimation

examples — such as right angle/rafter and stair calculations — that

will also help you build faster and more accurately.

BASIC OPERATION KEYS

On/Clear — Turns power on. Pressing once clears the

display. Pressing twice clears all temporary values.

Turns all power off, clearing all non-permanent registers.

+ – x Arithmetic operation keys.

÷ =

Ç + Percent (%) — Four-function percent. See page 30

for examples.

0–9and •Keys used for entering digits.

BBackspace Key — Used to delete entries one key-

stroke at a time (unlike the ofunction, which

deletes the entire entry).

CONVERT ÇKEY —

UNIT CONVERSIONS and SECOND FUNCTIONS

The Çkey is to convert between measurement units or to access

second functions, listed below:

ÇConvert — Used with the measurement keys to

convert between units or with other keys to access

special functions.

Ç x Clear All — Clears all values, including Memory.

Resets all permanent entries to default values

(except Preference Settings, which are retained).

Note: Use only when necessary, as it deletes all stored values.

XSquares the value in the display. For example, to

Square the value ten, enter 1 0 then press X.

Ç X x3— Cubes the value in the display. For example, to

Cube the value ten, enter 1 0 then press ÇX.

√Square Root Function — Used to find the Square

Root of a non-dimensional or area value

(e.g., 1 0 0 √ = 10).

KEY DEFINITIONS

USER’SGUIDE — 7

Ç √

Ç /

Ç ÷

Ç–

Ç π

Ç •

Ç =

Cube Root Function — Used to find the Cube Root

of a non-dimensional or volume value

(e.g., 1000Ç√= 10).

x10 y — Allows entry of an exponent. For example,

8Ç/14is 8 times 10 to the 14th power

(8x1014).

1/x — Finds the reciprocal of a number (e.g., 8

Ç÷= 0.125).

Change (+ / –) Sign — Changes the sign of the dis-

played value to negative or positive.

Pi — Constant = 3.141593

ArcK — Constant = 0.017453. This value is equiva-

lent to the constant of a 1° arc angle for a one-unit

value. The formula for this constant is π ÷ 180.

Degrees: inutes:Seconds — Converts between

:M:S and ecimal egree formats.

Note: Your calculator uses a floating d:m:s format (that is, dis-

plays decimal degrees to the maximum number of decimal points,

for greater accuracy). If you desire rounding to two decimal points

(0.00°), you must set your calculator via Preference Settings (see

page 107).

Access Preference Settings — Used to access

various customizable settings, such as dimensional

answer formats (see Preference Settings on page

107).

MEMORY and STORAGE FUNCTIONS

Your calculator has two types of Memory:

1) basic Memory or Semi-Permanent, Cumulative µ;

2) non-cumulative Storage Registers (M1-M3).

µSemi-Permanent emory — Adds any displayed

number, dimensioned or unitless, to the semi-per-

manent, accumulating Memory. Values can be sub-

tracted from this Memory using Ç µ.® ®

will recall and clear the Memory. Ç ® will swap

the value stored in accumulative Memory with the

value that is currently displayed.

8 — SHEET METAL/HVAC PRO CALC

Ç 1 Storage Register ( 1) — Stores the displayed

value in non-cumulative, permanent Memory (e.g.,

1 0 Ç 1,® 1 = 10). Good for storing a

single value, for future reference.

Note: Non-cumulative means it only accepts one value (does not

add or subtract) and a second entered value will replace the first.

Permanent means the value is stored even after the calculator is

shut off. To delete a stored value, enter a new value or perform a

Clear All (Çx).

Ç 2 Storage Register ( 2) — Same function as Ç

1.See above.

Ç 3 Storage Register ( 3) — Same function as Ç

1.See above.

RECA ®KEY

The ®key is used to recall or review stored values (e.g., ® p

to recall a previously entered pitch value). It is also used in review-

ing stored settings and Memory operation (see below).

® ® Clear + — isplays and clears M+.

® µ Recall + — isplays value stored in M+.

® 1 Recall 1 — Recalls the stored value in M1.

® 2 Recall 2 — Recalls the stored value in M2.

® 3 Recall 3 — Recalls the stored value in M3.

FEET-INCH-FRACTION and METRIC KEYS

The following keys are used for entering units of measure, with ease

and accuracy:

fEnters or converts to Feet. Also used with the i

and /keys for entering Feet-Inch values (e.g., 6

f9i1/2).

Note: Repeated presses after Çtoggle between Feet-Inches and

Decimal Feet (e.g., 6f9i1/2Çf= 6.791667

FEET; press fagain to return to Feet-Inch-Fractions).

USER’SGUIDE — 9

iEnters or converts to Inches. Also used with the /

key for entering fractional inch values (e.g., 9 i

1/2).

Note: Repeated presses after Çtoggle between Fractional

and Decimal Inches (e.g., 9i1/2Çi= 9.5

INCH; press iagain to return to Inch-Fractions).

/Fraction Bar — Used to enter Fractions. Fractions

may 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 resolution setting is auto-

matically used (e.g., entering 15/=or +

will display 15/16, based on the default fractional

resolution setting of 16ths.

meters — Enters or converts to Meters.

Ç m illimeters — Enters or converts to Millimeters.
