Fractional Settings
When you first receive your calculator it is
set to its default state. When in this state,
fractional values are rounded 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 – 15
Normal Fractional Mode
The default,
Normal Mode
([Conv] 7),
reduces a fraction to its lowest common
denominator (for example, 8/16 reduces
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.

“Paperless Tape” Feature
The “Paperless Tape” feature allows the
user to display the last 20 entries. While
in the Paperless Tape mode, your display
will look similar to this:
The display shows the entered or calculated value (12 Inch), sequence number
(04), and the math operator (in this case
it is “+”) for each entry. As you scroll
