Auto-Shut Off
Your calculator will shut itself off after
about 8-12 minutes of non-use.
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 o button once. At this
point, you must determine what caused
the error and re-key the problem.
Err
or Codes:
DISPLAY ERROR TYPE
OFLO Overflow (too large)
MATH Error Divide by 0
DIM Error Dimension error
ENT Error Entry error
POCKET REFERENCE GUIDE — 29
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., 10,000,000 mm is
shown as 10,000 m. Also applies to inches,
feet and yards.
Batteries
This model uses two (2) LR44 batteries
(included).
Should your calculator display become
very dim or erratic, replace the batteries.
Note: Please use caution when disposing of
your old battery, as it contains hazardous
chemicals.
Replacement batteries are available at
most discount or electronics stores. You
may also call Calculated Industries at
1-775-885-4900.
POCKET REFERENCE GUIDE — 30
Replacing the Batteries
To replace the batteries, slide open the
battery door (at top backside of unit) and
replace with new batteries. Make sure the
batteries are facing positive side up.
Reset Key
If your calculator should ever “lock up,”
press Reset — a small hole located to the
left of the O key — to perform a total
reset.
