APPENDIX E – 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 up to the nearest allowable frac-

tion. In most cases, Yardage calculations

will be displayed to the next available frac-

tion so you calculate enough material (no

shortages). 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 near-

est 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.
