Block/Brick Function (NOT AVAILABLE ON TRIG MODEL #4080) The Blocks function helps you quickly estimate the quantity of blocks or bricks required for building walls, walkways or other areas.
Circular/Arc Function Keys The circle key helps you quickly solve circular area, volume or arc problems. C Circle — Displays and calculates the following values, given an entered circle diameter* or radius: • Diameter (DIA) • Circle area (AREA) • Circumference (CIRC) *To enter a diameter (e.g., 10 Feet), press 1 0 f C. Ça Radius — Enters or calculates the circle radius (e.g., 5 f Ç a).
Column/Cone Function The Column and Cone function helps you quickly estimate volume and surface area of columns or cones. ÇC Column and Cone (Column/Cone) — With an entered diameter and height, the first and second presses of C (following Ç) will calculate the total volume and surface area of a Column; the third and fourth consecutive presses of C calculate the total volume and surface area of a Cone.
Drywall Function (NOT AVAILABLE Çh ON TRIG MODEL #4080) Drywall Sheets (Drywall) — Calculates the number of 4 x 8, 4 x 9, and 4 x 12 sheets for an entered or calculated area. Footing Function (NOT AVAILABLE ON TRIG MODEL #4080) The Footing function helps you quickly estimate the volume of concrete required for concrete footings. ÇW Footing — Calculates total quantity of concrete required for concrete footings based on an entered wall length and footing size.
Right Triangle/Roof Framing Keys Right Triangle: Using the Pythagorean theorem, the top row of keys on your Construction Master Pro will calculate instant solutions in dimensional format to right triangle problems (particularly, roof framing). The Construction Master Pro’s keys are labeled in easy to remember roofing terms. The right triangle is calculated simply by entering two of four variables: Rise, Run, Diagonal, or Pitch.
Çp Pitch Ratio or Slope (Slope) — Enters the Pitch as a ratio or Slope of a roof (or right triangle). For example, 0.58 slope is entered as • 5 8 Ç p. r Rise — Enters or calculates the Rise or vertical leg (height) of a right triangle. R Run —Enters or calculates the Run or horizontal leg (base) of a right triangle. d Diagonal — Enters or calculates the diagonal leg (hypotenuse) of a right triangle. Typical applications are “squaring up” slabs or finding common rafter lengths.
When calculating Regular and Irregular Jack rafter lengths, you will see the letters “JK” (Regular pitch side) or “IJ” (Irregular pitch side) and the corresponding jack number to the left of your calculator display. This will help you keep track of the descending sizes and which side the corresponding rafter is based on. H ÇH Hip/Valley Rafter — Finds the Regular or Irregular Hip/Valley rafter length. • Regular Hip/Valley Length: After right triangle/rafter values are entered or calculated (e.g.
(Cont’d) Note: You may set your calculator to display the Jack Rafter lengths in either ascending or descending order (see Preference Settings on page 83). Note: You may set your calculator to “mate up” with the Jack Rafters, rather than using the entered or default On-center spacing for both sides (see Preference Settings on page 83). ß5 Store On-center (o.c.) Spacing — Used to store a value other than the default of 16 Inches On-center (e.g.
Roof Materials/Covering Function The Construction Master Pro's Roof function provides a quick calculation of roof area, number of squares and bundles, and number of 4 x 8 sheets required for roof coverage.

Note: It is not possible for the calculator to include the nose/overhang measurement.
Çs Riser Limited — Used for situations when the riser height is limited by local code. When you press Ç s, the calculator will recalculate stair values so that the actual Riser Height will not exceed your stored desired Riser Height (e.g., it will never exceed the stored desired Riser Height of 7-1/2 Inches, if 7-1/2 Inches is the value stored using ß 7). To compensate for this limitation, the calculator will add one to the number of risers.
The Trig model (#4080) and Desktop (#44080) calculators have standard trigonometric keys, in addition to right triangle/rafter keys (e.g., Rise, Run, Diagonal), for advanced right triangle mathematics. The Sine, Cosine and Tangent of an angle are defined in relation to the sides of a right triangle. Using the Ç key with the trigonometric function displays the inverse (Arcsine, Arccosine, and Arctangent). These are used to find the angle for the Sine, Cosine, or Tangent value entered.
ENTERING DIMENSIONS Entering Linear Dimensions When entering Feet-Inch-Fraction values, enter dimensions from largest to smallest — e.g., Feet before Inches, and Inches before Fractions. Enter Fractions by entering the numerator (top), pressing / (fraction bar key), and then the denominator (bottom). Note: If a denominator is not entered, the fractional setting value is used.

RIGHT TRIANGLE AND ROOF FRAMING EXAMPLES 54 — CONSTRUCTION MASTER ® PRO / TRIG / DESKTOP
Roof Framing Definitions Rise: The vertical distance measured from the wall’s top plate to the top of the ridge. Span: The horizontal distance or full width between the outside edges of the wall’s top plates. Run: The horizontal distance between the outside edge of the wall’s top plate and the center of the ridge; in most cases this is equivalent to half of the span. Pitch: Pitch and slope are synonymous in modern trade language.
Regular Roof: A standard roof where the Hips and/or Valleys run at 45° and have the same pitch/slope on both sides of the Hip and/or Valley. Irregular Roof: A non-standard roof where the Hips and/or Valleys bisect two different pitches/slopes, or have “skewed wings” or irregular Jacks.

STAIR LAYOUT EXAMPLES Stair Layout Definitions Rise: The “floor-to-floor” or “landing-to-landing” rise is the actual vertical rise required for building a stairway after the finish flooring has been installed. Run: The run of a stairway is the amount of horizontal space required. The total run of a stairway is equal to the width of each tread multiplied by the number of treads. Desired Riser Height: The desired riser height is the amount of vertical rise you allow for each individual riser in the stairway.
Number of Risers: The number of risers includes both the first and the last riser of the stairway. Riser Overage or Underage: The riser overage or underage is the difference between the “floor-to-floor” rise and the total height of all of the risers. Many times the riser height does not divide evenly into the floor-to-floor rise and a small fraction of an inch is left over. A positive remainder is an overage, while a negative remainder is an underage.
Stairs — Given Only Floor-to-Floor Rise You’re building a stairway with a total rise of 9 Feet 11 Inches. Your desired riser height is 7-1/2 Inches and desired tread width is 10 Inches.
