PRG8528E-G 10/23/09 Page 2 The ProjectCalc Plus® MX was designed specifically for DoIt-Yourselfers in the United Kingdom and other countries that use Metric measurements. It helps you quickly figure project material quantities, linear distances, areas/volumes and material costs like a pro. Unlike other calculators, it works and converts directly in Metric measurements and can also convert to Imperial (feet-inch) units, including Square and Cubic, so you don’t have to figure tedious maths.
PRG8528E-G 10/23/09 Page 1 KEY DEFINITIONS Basic Keys o — On/Clear Key Turns power on. Pressing once clears the display. Pressing twice clears all temporary values. Ç o — Off Turns calculator off and clears all temporary/non-permanent registers. r — Recall Key Recalls stored values. Also works with Memory keys (see Memory keys for details). +–x÷= Arithmetic operation keys. 0 — 9 and • Keys used for entering numbers.
PRG8528E-G 10/23/09 Page 2 Ç 8 — Percent (%) Memory Ç = (M+) — Adds the displayed value to the semipermanent memory register (e.g., 1 5 0 Ç =). Semi-permanent means the value is cleared when the calculator is turned off. r = (M-R/C) — Recalls memory value (e.g., if 150 has been stored in Memory, pressing r = will display 150). Note: This function displays, but does not clear, the memory register. r r (M-R/C) — Displays and clears/deletes any value stored in the memory register.
PRG8528E-G 10/23/09 Page 3 / — 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). However, if you are only entering fractions of an inch, you don’t need to assign it, the calculator knows it is a fractional inch if you use the / key—e.g., enter 1/8 of an inch by pressing 1 / 8. Fractions can be entered as proper (1/2, 1/8, 1/16) or improper (3/2, 9/8).

INCH 0-1/16 INCH 0-3/64 INCH 0-1/16 INCH DIY (Do-It-Yourself) Project Keys The following keys help you quickly estimate material quantities for common DIY projects. In addition, the s key allows you to change material values for selected functions (i.e., you may replace the “default values” with your own). Note that these changes are stored until you change them again, or perform a “Clear All” by pressing Ç x.
PRG8528E-G 10/23/09 Page 5 tiles based on various Standard Tile Sizes (see “Default/ Standard Values for Materials”). Note: In the calculation, the corresponding tile size will show in the upper right of the display. Tile sizes are labeled in millimetres, not square millimetres (or sq. metres). In other words, a “100mm tile” is really 100mm x 100mm or a 10,000 square-mm (0.01 sq. m) size. Note: Calculation does not account for grout width, so you will need to adjust for this.
PRG8528E-G 10/23/09 Page 6 Ç 6 — Custom Tile Calculates number of tiles based on an entered area and a stored Custom Tile Size. This is used separately from the regular t key, which has various Standard Tile Sizes built in. 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. You must enter or find the tile size area first. Use length x width, then s 6. To recall this setting, press r 6.
PRG8528E-G 10/23/09 Page 7 Note on DIY Project Keys: For most problems, the DIY Project Keys will also find the Coverage Area given an entered Quantity. For example, you can find the Coverage Area of Paint given “X” Number of Litres/Cans. DEFAULT/STANDARD VALUES FOR MATERIALS The ProjectCalc Plus MX uses the standard (default) settings or material sizes listed below.
