Accuracy/Errors
Accuracy/Display Capacity — Your calculator has a twelve-
digit display made up of eight digits (normal display) and
four fractional digits. 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 
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)
MATH Error Divide by 0
DIM Error Dimension error
ENT Error Invalid entry error
Auto-Range — If an “overflow” is created because of an
input and calculation 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., 20,000,000 mm is shown as 20,000
m. Also applies to inches and feet.
Auto Shut-Off
Your calculator is designed to shut itself off after about 8-12
minutes of non-use.
