Page 3: Introducing Concretecalc
NTRODUCING ONCRETE Designed for today’s concrete profes- sional, the all-new ConcreteCalc™ adds even more power to the already pow- erful Construction Master line-up. Like earlier models, this calculator is so sim- ple to use, even the novice user can easily solve dimension-related prob- lems. -
Page 4: Key Definitions
Dimensions can only be converted with- in the same convention (i.e., linear, square or cubic). Also used to access spe- cial functions when used in combination with other keys as defined herein. 4 – ConcreteCalc™... - Page 5 Square Root — Used to find the square Note: Attempts to find root of a number. the square root of a linear or volume dimension will cause an “Error”. [Conv] [ ] — Finds the square of the displayed Note: Attempts to find the square of value.
- Page 6 This key can also be used in conjunction with the [ / ] key for enter- ing values in Fractional Inch format. Repeated presses of this key during conversions will toggle between Fractional Inch and Decimal Inch formats. 6 – ConcreteCalc™...
- Page 7 [ / ] Fraction Bar — This key is used to enter fractions. Fractions can be entered as proper (1 or less — 1/2, 1/8, 1/16) or improper (greater than 1 — 3/2, 65/64). For example, to enter 1/2, the key sequence would be: 1 [ / ] 2. If the denominator (the bottom number) is not entered, then the set fractional level (1/16, 1/2, etc.) is used.
- Page 8 Cubic Yard, or Kilograms per Cubic Meter. Default is 1.5 Tons/Cu. Yd. To set a dif- ferent weight per volume, for example, 2 Tons/Cu. Yd, press 2 [Conv] [%]. Value will be permanently stored. To recall stored value, press [Rcl] [%]. 8 – ConcreteCalc™...

Fractional Settings When ConcreteCalc is set to its default state, it rounds fractional values to the nearest 1/16 of an inch. However, you may program your preference for six different accuracy levels and two dif- ferent modes (Normal and Fixed), all of which remain in permanent memory until revised or reset. - Page 26 [Conv] [ / ] . In this way, you can see what fractional accu- racy level is set. Pressing [Conv] [ / ] again will turn the flashing denomina- tor off.
