POCKET REFERENCE GUIDE — 40
ACCURACY/ERRORS
Accuracy/Display Capacity – Your calcu-
lator 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 ERROR TYPE
OFLO Overflow (too large)
MATH Error Divide by 0
DIM Error Dimension error
ENT Error Invalid entry error
None Attempts to calculate stairs
without entering rise and run
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 automatical-
ly expressed in the next larger units
(instead of showing “ERROR”) –
