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 different 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 anything other than 1/16 normal mode, a star
(★) will appear in the bottom left of the display during power up to indicate a special
fractional setting has been stored within.
The fractional setting can be displayed at
any time by pressing [Rcl] [/].
User’s Guide – 25
Normal Fractional Mode
The default, Normal Mode ([Conv] 7),
reduces a fraction to its lowest common
denominator (for example, 8/16 rounds
to 1/2). If a fraction is entered having a
higher fractional accuracy than the current setting, the setting will be temporarily revised to the level of accuracy
of the entered value.
Fixed Fractional Mode
In the Fixed Mode ([Conv] 9), fractional results are displayed in the set fractional value, not reduced. Entries of
higher accuracy values will be rounded
to the nearest fraction of the accuracy
setting (for example, for a fraction level
setting of 1/16, an entry of 5 [/] 32 [=]
will result in a display of 3/16).
Flashing Denominator
Your calculator can be set to flash the
denominator (bottom) when entering
fractions by pressing [Conv] [/]. In this
way, you can see what fractional accuracy level is set. Pressing [Conv] [/]
again will turn the flashing denominator off. This is a permanent setting that
will remain until revised or reset.
26 – ConcreteCalc™
Paperless Tape Function
The Paperless Tape allows you to review
the last 20 entries of a calculation. To
access this function, press [Rcl] [=].
To review entered values, press [Rcl] [=]
to access the tape mode and then press
the [+] or [–] keys to either scroll forward
or backward through the entries.
While in the paperless tape mode, the display will show the entered or calculated
value, along with the sequence number of
entry (e.g., 01, 02, 03, etc.) and the math
operator (+, –, x, ÷, %) in the upper left
corner of the display.
If an equals ([=]) has been used in the
middle of a string and then added to, the
letters SUB (Subtotal) will display in the
upper left. If equals ([=]) was the last operation performed, the display will show TTL
(Total) as the last entry.
To exit the paperless tape mode, press
any key besides [Off], [+], [–]. Exiting the
tape will display the last entry (or TTL),
and allow you to either exit completely,
or continue using the last tape value for
another operation. For example, to store
the last value as “Length”, press any key
besides [Off], [+] or [–] and then press [=]
[Length].

Accuracy/Display Your calculator has
an eleven digit display. This is made up
of seven digits (normal display) and
four digits for the fraction. In a standard
calculation, each calculation is carried
out internally to 10 digits and rounded
to a 7-digit standard display. If the next
undisplayed digit is five or more, the
5/4 rounding technique adds 1 to the
least significant digit in the display. If
the digit is less than five, no rounding
occurs.
“Error” When an incorrect entry is
made, or an answer is beyond the calculator’s range, the word “Error” displays. To clear an error you must hit the
[On/C] key twice. When you have
determined what caused the error, rekey the problem. An “Error” will also
occur if you enter a mathematical
impossibility such as division by zero.
Auto-Range If an “overflow” occurs due
to an input or calculation that use more
digits than the display’s standard 7-digit
range, the answer automatically displays
in the next larger unit (instead of showing “Error”). i.e., 10,000,000 mm is
greater than the 7-digit range; therefore,
10,000 m is displayed instead. This auto-
APPENDIX A
54 – ConcreteCalc™
ranging also applies to other dimensional units such as inches to feet, feet to
yards, etc.
Battery & Auto Shut-Off Your calculator
is powered by a single 3-Volt Lithium
CR-2032 battery. This should last approximately 800 hours of actual use (1 year
plus for most people). Should the display become very dim or erratic, replace
the battery.
Warning! Please use caution
when disposing of your old batteries as
they contain hazardous chemicals.
Your calculator is designed to shut itself
off after about 8-12 minutes of non-use.
