Accuracy/Errors
Accuracy/Display Capacity — Your calculator has an eleven digit display made up of seven digits (normal display) and four fractional digits. Each calculation is carried out internally to
10 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 twice. At this point you must determine what caused the error and re-key the problem.
Auto-Range — If an “overflow” is created because of an input and calculation with small units that are out of the standard 7-digit range of the display, the answer will be automatically expressed in the next larger units
(instead of showing “Error”) — i.e.,
10,000,000mm is shown as 10,000m.
Also applies to inches, feet and yards.
