APPENDIX
ACCURACY/ERRORS
Accuracy/Display Capacity — 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 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 to display)
DIV Error Divide by 0
DIM Error Dimension error
ENT Error Entry error
None Attempt to calculate stairs
without entering Rise and Run
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, 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.
