APPENDIX
ACCURACY/ERRORS
Accuracy/Display Capacity
— Your calculator has a twelve-
digit display made up of eight digits (normal display) and
four fractional digits . You may enter or calculate values up
to 19,999,999 .99 . Each calculation 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
On/C
button
once . At this point, you must determine what caused the
error and re-key the problem .
Error 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 .
