ERROR AND CALCULATION RANGES

1. Errors

An error will occur if an operation exceeds the calculation

ranges, or if a mathematically illegal operation is attempted.

When an error occurs, pressing

<

(or

>

) automati-

cally moves the cursor back to the place in the equation

where the error occurred. Edit the equation (see page 4)

or press

N

to clear the equation.

In the statistical calculation formulas, an error will occur when:

•

the absolute value of the intermediate result or calcula-

tion result is equal to or greater than 1

×

10

100

.

•

the denominator is zero.

•

an attempt is made to take the square root of a negative

number.

Syntax error (Error 1):

•

An attempt was made to perform an invalid operation.

Ex. 2

@{

Calculation error (Error 2):

•

The absolute value of an intermediate or final calculation

result equals or exceeds 10

100

.

•

An attempt was made to divide by 0.

•

The calculation ranges were exceeded while performing

calculations.

Depth error (Error 3):

•

The available number of buffers was exceeded. (There are 8

buffers* for numeric values and 16 buffers for calculation

instructions). *4 buffers in STAT mode.

Equation too long (Error 4):

•

The equation exceeded its maximum input buffer (159 char-

acters). An equation must be shorter than 159 characters.

3.

Calculation Ranges

•

Within the ranges specified below, this calculator is

accurate to ±1 in the least significant digit of the

mantissa. When performing continuous calculations (in-

cluding chain calculations), errors accumulate leading

to reduced accuracy.

•

Calculation ranges

±10

and 0.

If the absolute value of an entry or a final or intermediate

result of a calculation is less than 10

, the value is con-

sidered to be 0 in calculations and in the display.

BATTERY REPLACEMENT

Notes on Battery Replacement

Improper handling of batteries can cause electrolyte leak-

age or explosion. Be sure to observe the following han-

dling rules:

•

Replace both batteries at the same time.

•

Do not mix new and old batteries.

•

Make sure the new batteries are the correct type (LR44).

•

When installing, orient each battery properly as indi-

cated in the calculator.

•

Batteries are factory-installed before shipment, and may

be exhausted before they reach the service life stated in

the specifications.

When to Replace the Batteries

If the display has poor contrast, the batteries require re-

placement.

Caution

•

Keep batteries out of the reach of children.

•

Exhausted batteries left in the calculator may leak and

damage the calculator.

•

Explosion risk may be caused by incorrect handling.

•

Batteries must be replaced only with others of the same

type.

•

Do not throw batteries into a fire as they may explode.

Replacement Procedure

1.

Turn the power off by pressing

@

F

.

2.

Loosen both screws and remove the battery cover. (Fig. 1)

Fig. 1

Fraction Calculations

•

A decimal number, variable, or exponent cannot be

entered as a fraction.

•

In all cases, a total of up to 10 digits including integer, nu-

merator, denominator and the symbol (

) can be entered.

•

If the number of digits to be displayed is greater than 10, the

number is converted to and displayed as a decimal number.

Coordinate Conversions

•

Before performing a calculation, select the angular unit.

(See page 6)

Time, Decimal and Sexagesimal Calculations

Conversion between decimal and sexagesimal numbers

can be performed. In addition, the four basic arithmetic

operations and memory calculations can be carried out

using the sexagesimal system.
