APPENDIX I — ACCURACY, AUTO SHUT-OFF,
BATTERIES, ERRORS
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 ten 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 hit the o button once. At this point
you must determine what caused the error and re-key the problem.
Error Codes:
Display
0-fL0
EXP Error
DIV Error
DIM Error
ENT Error
TYP Error
TRIG Error
None
Auto-Range — If an "overflow" is created because of an input and
calculation with small units that are out of the standard range of the
display (e.g. 19,999,999.99), 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., 100 million mm—1.000000
