Accuracy/Errors
Accuracy/Display Capacity
— Your calcula-
tor has a twelve-digit display made up of
eight digits (normal display) and four frac-
tional digits. You may enter or calculate
values up to 19,999,999.99. Each calcula-
tion is carried out internally to twelve digits.
Most material calculations will result in an
answer rounded up two places. Press the
= key to see the non-rounded value.
Errors
— When an incorrect entry is made,
or the answer is beyond the range of the
calculator, it will display an error. To clear
an error condition you must hit the o
button once. At this point, you must
determine what caused the error and
re-key the problem.
Err
or Codes:
DISPLAY ERROR TYPE
OFLO Overflow (too large)
MATH Error Divide by 0
DIM Error Dimension error
ENT Error Entry error
Auto-Range
— If an “overflow” is created
because of an input and calculation with
small units that are out of the standard
seven-digit range of the display, the
answer will be automatically expressed in
the next larger units (instead of showing
“OFLO”) — e.g., 20,000,000 mm is shown
as 20,000 m. Also applies to inches, feet
and yards.
