Accuracy/Errors
Accuracy/Display Capacity — Your calculator has an eleven-digit dis-
play made up of seven digits (normal display) and four fractional digits.
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 [On/C] button once. At this point
you must determine what caused the error and re-key the problem.
Error Codes:
Display Error Type
0-fL0 Overflow (too large)
Error 1 As above, but for exponents (value > 1e74)
Error 2 Divide by 0
Error 3 Dimension error
Error 4 Entry error
Error 5 Type error
Error 6 Trig. error (for example, tan of 1 foot)
Error 7 Does not occur (tape error)
None Attempt to calculate stairs without entering rise or
run
Auto-Range — If an “overflow” is created because of an input and cal-
culation with small units that are out of the standard seven-digit range
of the display, the answer will be automatically expressed in the next
larger units (instead of showing “ERROR”) — e.g., 10,000,000 mm is
shown as 10,000 m. Also applies to inches, feet and yards.
þþ Note: If Exponential Notation is activated through the Preference
Setting, the value will be shown in scientific notation (e.g., 10 million
mm—1.0000
07
mm).
