Convert [Conv] Key—Unit Conversions and Second Functions The [Conv] key is to convert between measurement units or to access second functions, listed below: [Conv] — Convert Used with the measurement keys to convert between units or with other keys to access special functions. [Conv] [ x ] — All Clear Clears all values, including Memory. Resets all permanent settings to defaults. þ Note: Use only when necessary, as it deletes all stored values. [Conv] [%] — x 2 Squares the value in the display.
[Conv] [ 9 ] — Total Cost Computes total material cost given a unit dimension and an entered Per Unit Cost. [Conv] [ Stor ] — Access Preference Settings Used to access various customizable settings, such as dimensional answer formats (see Preference Settings on page 96). Memory and Storage Functions Your calculator has two types of Memory: 1) basic memory or semi-permanent, cumulative [M+]; 2) non-cumulative Storage Registers (M1) and (M2).
Recall [Rcl] Key The [Rcl] key is used to recall or review stored values (e.g., [Rcl] [Pitch] to recall a previously entered pitch value). It is also used in reviewing stored settings, or in Paperless Tape and Memory operation (see below). [Rcl] [ = ] — Paperless Tape Accesses the paperless tape mode (see “Paperless Tape,” page 36), which keeps track of your past 20 entries. Useful for checking strings of numbers. [Rcl] [Rcl] — Clear M+ Displays and clears M+.
DIMENSIONAL MEASUREMENT UNIT KEYS The following keys are used for entering units of measure, with ease and accuracy: [Yds] — Yards Enters or converts to yards. [Feet] Enters or converts to feet. Also used with the [Inch] and [/] keys for entering feet-inch values (e.g., 6 [Feet] 9 [Inch] 1 [/] 2). Note: Repeated presses after [Conv] toggle between feet-inches and decimal feet (e.g., 6 [Feet] 9 [Inch] 1 [/] 2 [Convert] [Feet] = 6.791667 feet; press [Feet] again to return to feet-inch-fractions).
[Conv] [ 2 ] — Acres Enters or converts (a square value) to acres. [Conv] [ 0 ] — Board Feet Enters or converts cubic values to board feet. One board foot is equal to 144 cubic inches. WEIGHT KEYS [Conv] [ 1 ] — Kilograms Enters or converts (a weight or volume value) to kilograms. A dimensioned volume will convert using the stored weight per volume value. [Conv] [ 3 ] — Metric Tons Enters or converts (a weight or volume value) to Metric tons.
Construction Project Keys The following Construction Project Keys help you instantly figure quantities and costs of materials, so you can build like a pro! Block/Brick Key The Block key helps you quickly estimate the quantity of blocks or bricks required for building walls, walkways or other areas. [Block] — Number of Blocks or Bricks Calculates the total number of concrete blocks required to fill a given area. Uses a standard block/mortar area of 128 square inches.
Circular Function Keys The circle key helps you quickly solve circular area, volume or arc problems. [Circ] — Circle Displays and calculates the following values, given an entered circle diameter* or radius: • • • diameter circle area circumference *To enter a diameter (e.g., 10 feet), press 10 [Feet] [Circ]. [Conv] [Diag] — Radius Enters or calculates the circle radius (e.g., 5 [Feet] [Conv] [Diag]).
[Rise] — Rise (Segment Rise) Used with [Run] or [Conv] [Diag] to find the rise or the radius of a circular segment. If the chord length and radius have been entered, this key will display the segment rise of the circular segment. Column/Cone Key The Column and Cone functions help you quickly estimate volume and surface area of columns or cones. [Column] Calculates the total volume and surface area of a column using the values stored in [Circ] and [Rise].
Right Triangle/Roof Framing Keys Right Triangle: Rise Unit Rise Pitch = Unit Run Diagonal Pitch ° Run Using the Pythagorean theorem, the top row of keys on your Construction Master Pro provide 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: 1) Rise, 2) Run, 3) Diagonal or 4) Pitch.
þ Note: An entered (vs. calculated) pitch is a permanent entry. This means that it will remain stored even after you turn the calculator off. To change the pitch, simply enter a new pitch value. In contrast, a calculated pitch value is not permanently stored. This means that the calculator will return to the pitch value you last entered when you clear the calculator or press [On/C] twice. [Rise] Enters or calculates the rise or vertical leg (height) of a right angle.
Hip/Valley and Jack Rafter Keys Irregular Side [I/Jack] Hip Rafter Common Side [Jack] Jack Rafters 16” The Construction Master Pro uses the rise, run, diagonal, pitch and o.c. spacing values to compute regular (45°) and irregular (non-45°) Hip/Valley and Jack rafter lengths (excluding wood thickness, etc.).
• Subsequent presses of the [Hip/V] key will also display Plumb, Level, and Cheek cut angle values in degrees. [Conv] [Hip/V] — Irregular Pitch Enters the irregular or secondary pitch value used to calculate lengths of the irregular Hip/Valley and Jack rafters. You may enter the irregular pitch as: • • • þ a dimension: 9 [Inch] [Conv] [Hip/V] an angle: 30 [Conv] [Hip/V] a percentage: 75 [%] [Conv] [Hip/V] Note: An entered irregular pitch can be recalled by pressing [Rcl] [Conv] [Hip/V].

CONNECTING THE AC ADAPTER Your calculator operates on AC power so you don’t have to use batteries. To connect the AC adapter, first make sure your calculator is turned off (power switch to “Off”). Then, plug the AC power plug into a power outlet (Step 1) and plug the connecting end into the small outlet at the end base of your calculator (Step 2), as shown. If you do not want to use AC power but prefer to run the unit on battery power instead, you must purchase and install batteries.
USING BATTERY POWER As your Construction Master Pro DT Printer works on AC power, it does not come with batteries. You can purchase AA batteries at your local RadioShack, or any store that sells batteries. • Batteries: Four AA batteries 1. 2. 3. 4. Switch power to “Off.” Turn calculator over and remove the battery cover by sliding it in the direction of the arrow. See (1) on figure below. Insert 4 AA batteries, making sure the “-” and “+” on the calculator match the “-” and “+” on each battery.
REPLACING THE PAPER ROLL You can find replacement printer paper for calculators at your local Staples, Office Depot, or other office supply store: • Paper Type: Width: 57mm (2-1/4”); Diameter: 86mm (3-3/8”) or less. 1. Cut leading edge of paper roll first, prior to inserting (as torn paper will jam). See (A) on next page. 2. Insert the leading edge of the paper roll into the slit located on the back of the calculator. See (B) on next page. 3. Turn the power on (switch to Print Mode or “Print”). 4.
