APPENDIX
ACCURACY/ERRORS
Accuracy/Display Capacity – Your
calculator has a twelve digit display. This
is 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.
Errors – When an incorrect entry is made,
or the answer is beyond the range of the
calculator, it will display the word "ERROR."
To clear an error condition you must press
the o button once. At this point you
must determine what caused the error and
re-key the problem.
Error Codes
DISPLAY
OFLO
MATH Error Divide by 0
DIM Error
ENT Error
None
Auto-Range – If an "overflow" is created
because of a calculation with small units
that are out of the standard digit range of
the display, the answer will be automatically
expressed in the next larger units
(instead of showing "ERROR") e.g.,
20,000,000 mm is shown as 20,000 m.
Also applies to inches, feet and yards.
Note: If exponential notation is activated through the
preference setting, the value will be shown in scientific
notation (e.g., 20 million mm – 2.00000 07 mm).
ERROR TYPE
Overflow (too large)
Dimension error
Invalid entry error
Attempts to calculate stairs
without entering rise and run
