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 data, how to store values, etc., before proceeding to the examples. Key Definitions Basic Function Keys 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 non-permanent registers. r Recall Key ─ Recalls stored values.
Convert Key Functions Ç Çx Ç– Ç÷ Convert Key ─ Used with the dimensional unit keys to convert between dimensions (e.g., cubic millimetres to cubic metres), with the “Project Keys” to calculate various material quantities (see “DIY Project Keys”), or with other miscellaneous keys to access special functions, such as those listed below. Clear All ─ Clears all values, including memory. Sets the calculator back to its default settings.
(contʼd) i Inch — 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 swap between Fractional and Decimal Inches. / Fraction Bar — Used to enter fractions (e.g., 1-1/2 inches is entered 1 i 1 / 2). Note: You need to assign the “whole” inch value (e.g., 1 i) first using the i key, then enter the fraction (1 / 2).
Entering Square or Cubic Values To assign a measurement 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 square metres, press 2 5 m m. To enter 25 cubic metres, enter 2 5 m m m. Fraction Resolution (for Imperial Measurements Involving Fractions) Your calculator is set to display fractional values to the nearest 16th of an inch (default setting). The 1/16-inch resolution can be displayed by pressing r /.
(contʼd) s p Coverage — Stores a new Paint Coverage per Litre (see grid, “Default/Standard Values for Materials,” for current setting). To recall your setting, press r p. w Note: Calculation does not account for grout width, so you will need to adjust for this. Also note that this key cannot be customized; you must use Custom Tile Keys Ç 6 if you are using other than the stored tile sizes.
(contʼd) Ç4 8 x 4 Sheets — Calculates number of plywood/drywall sheets based on an entered linear distance or area and Standard Sheet Sizes (see “Default/Standard Values for Materials”). s6 Stores Custom Tile Size — Stores Custom Tile Size. You must enter or find the tile size area first. Use length x width, then s 6. To recall this setting, press r 6. Ç1 Slabs — Calculates the number of slabs of concrete required, based on an entered length or area and Standard Slab Sizes.
Key Ç0 BTU (British Thermal Unit) — Calculates the number of BTUs required to heat a room given the room’s cubic capacity.

You may also use the ProjectCalc Plus mx to determine the cost of materials, if you know the material’s cost per unit. It’s a simple calculation, but useful, as you can quickly convert directly from a previously calculated quantity (e.g., cubic metres) to a total Euro cost format. See the following examples. Auto Shut-Off and Battery Reset If your calculator should ever “lock up,” press Reset — a small hole located above the b key/upper right. Use the end of a paper clip to press the button.
