APPENDIX D – ACCURACY, ERRORS
AND AUTO SHUT-OFF
Accuracy/Errors
Accuracy/Display Capacity – Your calcu-
lator has a seven digit display. You may
enter or calculate values up to 9999999.
Each calculation is carried out internally to
twelve digits.
Your calculator is designed to calculate
Yardage to the nearest allowable fraction.
In most cases, Yardage calculations will be
displayed to the next available fraction so
you calculate enough material (no short-
ages). Your calculator will, however, round
down if the calculation is less than 0.01 to
the nearest available fraction. Fractional
Inches are rounded to the nearest fraction.
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
N button once. At this
point you must determine what caused the
error and re-key the problem.
