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. 
The fractional level can be revised by
using the keystrokes below:

Keystroke

Fraction Setting

[Conv]  1 

1/16

[Conv]  2

1/2

[Conv] 3

1/32

[Conv]  4

1/4

[Conv] 6

1/64

[Conv]  8

1/8

Note:

Whenever the calculator is set to any-

thing other than 1/16 normal mode, a star
(

★

) will appear in the bottom left of the dis-

play during power up to indicate a special
fractional setting has been stored within.
The fractional setting can be displayed at
any time by pressing
