KEY DEFINITIONS o - On/Clear Key Turns power on. Pressing once clears the display. Pressing twice clears all temporary values. Ç o - Off Turns all power off, clearing all nonpermanent registers. r - Recall Recalls stored values. +–x÷= Arithmetic operation keys. 0 - 9 and • Digits used for keying in numbers. Dimensional Unit Keys y - Yards Key Enters or converts to Yards. f - Feet Key Enters or converts to Feet as whole or decimal numbers.
i - Inch Key Enters or converts to Inches. Entry can be whole or decimal number. Also used with the / key for entering Fractional Inch values (e.g., 9 i 1 / 2 ). Repeated presses during conversions toggle between Fractional and Decimal Inches. / - Fraction Bar Key Used to enter fractions. Fractions can be entered as proper (1/2, 1/8, 1/16) or improper (3/2, 9/8). m - Meter Key Enters or converts to Meters.
Ç – - Change Sign (+ / -) Toggles displayed value to positive or negative. (Repetitive presses of Ç – will change sign from positive or negative.) Ç ÷ - Square Root Finds Square Root of value in display. Ç + - x2 Finds Square of value in display. Ç s - Pi (π) Constant 3.141593. Memory s m (M+) - Adds or stores a value in the semi-permanent memory (e.g., 1 5 0 s m). Semi-permanent means the value is cleared when the calculator is turned off. Ç – s m (M-) - Subtracts a value from the semi-permanent Memory (e.
Entering Square or Cubic To label a dimension as “Square” or “Cubic,” enter the value, then press the desired dimension key twice for Square and three times for Cubic. For example, to enter 25 Cubic Yards, press 2 5 y y y. Fraction Resolution Your calculator is set to display Fractional values to the nearest 16th of an Inch (default setting). Press r / to access the fraction resolution setting. Repeated presses of / will then revolve through the available settings: 1/16, 1/32, 1/64, 1/2, 1/4 and 1/8.
w - Wallpaper Calculates number of rolls of wallpaper, based on an entered area and a stored Wallpaper Roll Coverage Area (see below). s w - Stores Wallpaper Roll Coverage Area Stores Coverage Area (in Square Feet) per Wall-paper Roll. To recall this setting, press r w. Default is 56 Square Feet per roll. t - Tile Finds the number of tiles, based on an entered area and a user-stored Grout Width (see below).
d - Deck Finds the number of boards for a deck, based on an entered area and a stored Board Width or Board On-Center (see below). Repeated presses will scroll between numbers of boards for various “standard” board lengths (12’, 10’, 8’, 20’, 18’, 16’ and 14’). s d - Stores Board Width/O.C. Stores Board Width or Board On-center for deck or fence calculations. To recall this setting, press r d. Also used to store the board On-center for Fence Spacing. Default is 5-11/16 Inches.
Ç 8 - Studs Calculates number of studs, based on an entered linear distance and a stored On-Center Spacing (see below). Note: Automatically adds one stud to the calculated answer to account for one on the end. s 8 - Stores On-Center for Studs Stores On-center spacing for studs in Inches. To recall this setting, press r 8. Default is 16”. Ç 9 - Roof Bundles Calculates number of bundles of roof shingles, based on an entered roof area and a stored Area per Roof Bundle (see below).
Ç 6 - Custom Tile Calculates number of tiles based on an entered area and a stored Custom Tile Size (see below). This is used separately from the regular Tile Key ( t ). Note: Calculation does not account for grout width for custom tiles, so you will need to adjust for this. s 6 - Stores Custom Tile Size Stores Custom Tile Size in Square Inches. To recall this setting, press r 6. Default is 24 Square Inches. Ç 1 - Concrete Calculates the number of bags of concrete required, based on an entered volume (e.g.
Ç 3 - Block Calculates the number of standard 128-Square Inch blocks (with 1/2” mortar), based on an entered linear distance or area and a stored Block Area (see below). s 3 - Stores Block Area Stores Block Area in Square Inches. To recall this setting, press r 3. Default is 128 Square Inches (includes 1/2” mortar). Note: When calculating the number of blocks for an entered length, calculator uses a 16-Inch block length, as the majority of blocks are 16” long.
Ç = - Mulch Calculates the number of bags of mulch you’ll need, based on an entered volume and a stored Volume per Bag (see below). s = - Stores Volume per Bag of Mulch Stores the Volume per Bag of mulch. To recall this setting, press r =. Default is 2 Cubic Feet per bag. BASIC DIMENSIONAL MATH Linear Conversions Convert 15 Feet 9-1/16 Inches to other units of measure.
