GETTinG STaRTEd

You may want to practice getting a feel for your calculator keys

by reading through the key denitions and learning how to enter

basic feet-inch-fractions and metric, how to store values in

Memory, etc., before proceeding to the examples.

Order of Operations

Unlike other Calculated Industries calculators, which use the

Chaining Method of Operations, this calculator uses the Order

of Operation Method.

● Chaining Method (“as entered”): 10 + 4 x 5 = 70

● Order of Operations: 10 + 4 x 5 = 30

The Order of Operations method of computing is based on the

following order of precedence:

1) Expressions inside of parentheses

2) Single-variable functions that perform the calculation and

display the result immediately (trig functions, square,

square root, xy, percent, reciprocal, angle conversions)

3) Multiplication and division

4) Addition and subtraction

5) Equals (completes all operations)

If you need to calculate using the Chaining Method, you can

change this in your calculator Preference Settings.

Basic Function Keys

On/Clear Key – Turns on power. Pressing once

clears the last entry and the display. Pressing twice

clears all non-permanent values.

Off – Turns all power off. Clears all non-

permanent memory.

Arithmetic operation keys



– Keys used for entering

and numbers.

 Convert – Used with the dimensional keys to

convert between units or with other keys to access

special functions.

Store – Used for storing values.

Recall –Used with other keys to recall stored

values and settings.

 Memory Clear (M-R/C) – Clears Memory without

changing current display.

Accumulative Memory – Adds value to

Accumulative Memory.

 (M-) –Subtracts value from Accumulative Memory.

Dimensional Function Keys

Feet – Enters or converts to feet as whole or

decimal numbers. Also used with and keys

for entering feet-inch values (e.g., 

). Repeated presses during conversions toggle

between fractional feet-inch and decimal feet.

6 — Pl U m b i n G Ca l C ™ Pr o

Inch – Enters or converts to inches. Entry can be

whole or decimal numbers. Also used with for

entering fractional inch values (e.g., 

). Repeated presses during conversions toggle

between fractional and decimal inches.

Fraction Bar – 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. Results are always

shown in typical building fractional format.

Enters or calculates the Run.

Enters or calculates the Travel (Diagonal). Used to

calculate pipe length.

Defines the pipe material used for various pipe

sizes used in Pressure Loss calculations.

Defines the nominal Pipe Size being used.

 Denes the Pipe Type based on Pipe Material.

Enter or calculate volumetric Flow Rate through

a Pipe.

(Velocity) – Enter or calculate Velocity and convert

between feet per second, feet per minute and

meters per second.

Enter value for Force/Area calculations. Calculate

Pressure Loss. Convert between units of pressure.

Calculate Force and convert between lbf, newton.

Enter for Flow, Velocity, Pressure, Force

calculations. Calculate Area given values for Flow/

Velocity or Force/Area. If a Pipe Size has been

selected, Area will match Inside Dimension for pipe

of the current material and type.

Miscellaneous Functions

Displays value of π (3.141593).

(+/–) Toggle displayed value between minus and

plus value.

Clear All – Returns all stored values to the default

settings. (Does not affect Preference settings.)
