Mode:
There are four buttons allow the user to select from 4 different
"modes": FT-IN (foot inch and fractions ), Inch ( inch and fractions),
DEC (decimal), and MM (millimeter). The current selected mode will be
indicated with a blue button, while the other buttons will indicate a
green color (signaling that the button can be depressed). Note, during
computations, these buttons will be disabled and turn red until an
operation is performed (+, -, =, etc). Normally conversions take place
after a series of computations, but occasionally a user may want to
just enter a number and perform a conversion. For example, convert 4'-3
1/2" to inch, decimal, or mm. The user would enter 4'-3 1/2" and press
the "=" key, the mode buttons would become enabled and the user selects
inch, dec, or mm.
How
to input data:
Entering input in the
FT-IN mode: The
input key stokes have been optimized for the fewest key stokes possible
and will be equal to the qty of digits that represent the feet, the
foot mark, one key for the inch, and one key for the fraction. So for
example, 12'-11 15/16" will be entered with 5 key inputs: "1", "2",
"FT", "11", and "15/16". Additionally, thirty-seconds of an inch can be
entered with the same amount of keystrokes. If the user wishes to
access the x/32 buttons, just rotate the calculator in your hand
"counterclockwise" (approximately 10 degrees). The x/32" buttons will
appear over the x/16th keys. If the user just wants x/16, no rotation
is required.
Note that the
keys change after
the "ft" button is pressed, exposing the "10" and "11" keys. Also note
that after one of the inches are selected that all of the fraction keys
are displayed. It is at this point where the user can rotate the
calculator and the x/32 keys are exposed.
Entering input in
the INCH mode:
The input key stokes have been optimized for the fewest key stokes
possible and will be equal to the qty of digits that represent the
inches, the inch mark, and one key for the fraction. So for
example, 11 15/16" will be entered with 4 key inputs: "1",
"1",
"INCH", and "15/16". Additionally, thirty-seconds of an inch
can
be entered with the same amount of keystrokes. If the user wishes to
access the x/32 buttons, just rotate the calculator in your hand
"counterclockwise" (approximately 10 degrees). The x/32" buttons will
appear over the x/16th keys. If the user just wants x/16, no rotation
is required.
Note
that the keys change after the "in" button is
pressed, all of the fraction keys are displayed.
Note: the current mode
effects how
the data is displayed on the main calculator view, the triangle input
view and the triangle results view.
STO:
There are three storage areas for triangle input. STO 1, STO 2, and STO
3.
Whatever value is presently displayed will be stored in any of the
three storage locations.
