GETTING STARTED You may want to practice getting a feel for your calculator keys by reading through the key definitions 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.
Using Parentheses Your calculator has parentheses keys and for performing mathematical operations. (In the Order of Operations method, expressions inside of parentheses are performed first.) The calculator offers up to 21 levels of parenthesis: 1) First parenthesis level opened – press for one rightsided parenthesis. 2) Second level opened – press a second time for two right-sided parentheses . 3) Third level opened – press a third time for three rightsided parentheses .
KEY DEFINITIONS 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 nonpermanent memory. Arithmetic operation keys – and Keys used for entering numbers. Convert – Used with the dimensional keys to convert between units or with other keys to access special functions. Store – Used for storing values.
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. 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.
Weight/Volume Functions Weight/Volume – Stores a new weight volume as pounds per cubic feet or other format as shown below. Default value is 62.42796 pounds per cubic foot of water (1000 kg/m3). ● Pounds per cubic foot ● Pounds per cubic inch ● Pounds per gallon ● Kilograms per cubic meter ● Kilograms per liter Pounds (lbs) – Enters or converts a weight or volume value to pounds. Kilograms (kg) – Enters or converts a weight or volume value to kilograms.
Pipefitting Project Keys Offset Slope Travel Angleº Enters or calculates a linear Slope, Slope Angle, or Percent Grade. The linear slope is the amount of "Offset" over 12 inches of "Run." Values may be entered as: ● a Dimension: ● an Angle or Degrees: ● a Percentage (percent grade): Once an angle or slope has been entered, consecutive presses of will convert to the remaining formats listed above. Take-Out (T.O.
Defines the Pipe Material. (Steel, Stainless Steel, Brass, Aluminum, Cast Iron, PVC or Copper). Elbow Type – Defines the type of radius (long or short) and whether a factory or field cut 45˚ Butt Weld elbow is being used. Default value is Butt Weld – Long. Enters the nominal Pipe Size and provides data pertaining to the entered size. Pipe Type – Defines the Pipe Type based on Pipe Material. Cutback – Calculates pipe Cutback after Bend Angle and Offset are entered.
Miscellaneous Functions Open parenthesis key Close parenthesis key Enters an exponential value other than x 2 or Square Root Exponential Root Value – Enters the exponential root value (x1/y) Pi – Displays value of Reciprocal (1/x) – Finds the reciprocal of a number (e.g., 0.125). Change Sign (+/–) – Toggle displayed value between minus and plus value Clear All – Returns all stored values to the default settings. (Does not affect Preference settings.

PERCENTAGE CALCULATIONS The keys can be used for finding a given percent of a number or for working add-on, discount or division percentage calculations. It can be used with any type of number, in any dimension (feet, inch, millimeter, etc.) and any type of convention (non-dimensioned, linear, square or cubic). Calculating Percentages Find 18% of 500 feet: KEYSTROKE DISPLAY 0. 90 FEET 0 INCH Take 20% from 286 Feet 6 inches: KEYSTROKE DISPLAY 0.
MEMORY OPERATION Whenever the key is pressed, the displayed value will be added to the Memory. Other memory functions: FUNCTION KEYSTROKE Add to Memory Subtract from Memory Recall total in Memory Display/Clear Memory Clear Memory Memory is semi-permanent, clearing only when you: 1) turn off the calculator; 2) press ;; 3) press ;; 4) press (Clear All).
Using Memory Storage Keys (M1 - M9) In addition to the standard cumulative Memory (as previously described), your calculator has nine independent Storage Registers – M1 through M9 – that can be used to permanently store single, noncumulative values. The following example shows the use of M1 ( ). To use M2 - M9, replace the presses of the key with presses of the corresponding number key ( - ). You can replace a value in one of these Memory registers by storing a new value in place of the stored value.
PAPERLESS TAPE The Paperless Tape allows you to display and review the last 30 entries of a calculation. accesses the tape mode and or scrolls forward or backward through the entries. Note: The Paperless Tape is cleared each time is pressed twice, the unit is shut off, or an All Clear ( ) is performed. Paperless Tape Function — Normal Mathematics 1. Enter a string of numbers: KEYSTROKE DISPLAY 0. 4 FEET 0 INCH 9 FEET 0 INCH 15 FEET 0 INCH 22 FEET 0 INCH 2.
CALCULATE COSTS The Cost function provides the total cost for material, based on a stored unit cost and an entered quantity of material. This is convenient for quickly calculating costs on a job that requires many of the same kind of items. Example: You are doing an installation that includes 120 feet of pipe that comes in 10' lengths at $3.21 per 10' pipe. KEYSTROKE Store the unit cost of the pipes needed: DISPLAY 0. COST PER 3.
USING THE PIPE TRADES PRO Pipe Material Key The Pipe Material key lets you choose a pipe material, which defines the available sizes and surface roughness used by the calculator.

Find the arc lengths for an odd bend angle of 37° for 12” pipe. KEYSTROKE 1. Enter the Pipe Size: 2. Enter the known bend angle: INSIDE ARC ARC CENTE R OUTSI DE A RC Note: All Take-Out calculations are based on Standard type steel pipes. O.D.
Cut Length – Known Take-Out Value The Pipe Trades Pro can solve cut lengths for materials and fittings not currently built into the calculator by entering a known Take-Out value. Find the cut length (end-to-end) for a pipe offset with a 10” Offset and bend angle of 45°. This example assumes 4” Type 40 PVC, with a known Take-Out value of 2 and 3/16 inches. Note: Override the Welder’s Gap for this example. KEYSTROKE DISPLAY 1. Select PVC: (press until PLAStIC id displayed) 2.
Combination Rolling Offset Unlike a regular rolling offset, the entry and exit fittings for a combination rolling offset are on different planes and therefore have different fitting angles from each other. Horizontal to Vertical Find the pipe length, and entry and exit fitting angles for a combination rolling offset with a vertical pipe exit, given a Roll of 23”, Offset of 15”, and Advance of 29”. Use the box in Diagram 1 to review the entry and exit pipe perspectives.

Horizontal to Horizontal In the next example, the same box dimensions are used except the exit fitting now creates a pipe exit horizontally instead of vertically. The entry fitting angle of 43.44° and pipe length of 39 and 15/16 inches remain the same since the dimensions in this example are the same (if they were different, steps 1 and 2 on the previous pages could be repeated to calculate them).
