How to Operate

Mode key

1. KEY LAYOUT (EL-W535TG)

Read Before Using

This operation guide has been written mainly based on the EL-W535TG model.

And some functions described here are featured on the EL-W516T model only.

Note that key operations and symbols on the display may differ according to the model.

2nd function, ALPHA keys

Pressing these keys will enable

the functions written in orange

(2nd F) or green (ALPHA) above

the calculator buttons.

This calculator can operate in four different modes as follows.

[

NORMAL mode

]•

Mode = 0; normal mode for

performing normal

arithmetic and function

calculations.

ON/C, OFF key

Written in orange

above the ON/C key

[STAT mode]

•Mode = 1; mode for

performing 1- or 2-variable

statistical calculations. To

select the sub-mode, press

the corresponding number

key after .

HOME key

Pressing this key will return to

NORMAL mode.

Single variable statistic calculation

Linear regression calculation

Quadratic regression calculation

Euler Exponential regression calculation

Logarithmic regression calculation

Power regression calculation

Inverse regression calculation

Exponential regression calculation

[DRILL mode]

•Mode = 3; mode for

performing drill calculations.

To select the drill sub-mode,

press the corresponding

number key

after .

(MATH): Math drill

(TABLE): Multiplication table drill

[TABLE mode]

•Mode = 2; mode for

showing the changes in

values of a function in table

format.

NOTE:

The EL-W516T model has another modes (Complex, Equation, Matrix, Vector and

Distribution modes).

The actual display does not appear like this.

For convenient and easy operation, this model can be used in one of five display modes.

The selected display status is shown in the upper part of the display (Display format indicator).

Note: If more 0’s (zeros) than needed are displayed when the ON/C key is pressed, check

whether or not the calculator is set to a Special Display Format.

• Floating decimal point format 1/2 (N1/N2 is displayed)*1

Valid values beyond the maximum range are displayed in the form of [10-digit

(mantissa) + 2-digit (exponent)]

• Fixed decimal point format (FIX is displayed)

Displays the fractional part of the calculation result according to the specified

number of decimal places.

• Scientific notation (SCI is displayed)

Frequently used in science to handle extremely small or large numbers.

• Engineering scientific notation (ENG is displayed)

Convenient for converting between different units.

RESET SWITCH

Reset switch

RESET

If the calculator fails to operate

normally, press the reset switch on

the back to reinitialize the unit. The

display format and calculation mode

will return to their initial settings.

NOTE:

Pressing the reset switch

will erase any data stored

in memory.

4. DISPLAY FORMAT AND

DECIMAL SETTING FUNCTION

*1 The calculator has two settings for displaying a floating point number:

NORM1 (default setting) and NORM2. In each display setting, a number is

automatically displayed in scientific notation outside a preset range:

• NORM1: 0.000000001 <

x <

9999999999

• NORM2: 0.01 <

x <

9999999999

Let’s compare the display result of

[10000 8.1 =] in each display format.

(NORM1 mode)

(Mixed fractions)

Display format indicator

5. EXPONENT DISPLAY

0.32 191.6

(FIX mode, TAB = 3)

(SCI mode)

(ENG mode)

(NORM1 mode)

The distance from the earth to the sun is approx. 150,000,000 (1.5 x 108) km. Values

such as this with many zeros are often used in scientific calculations, but entering the

zeros one by one is a great deal of work and it’s easy to make mistakes. In such

cases, the numerical values are divided into mantissa and exponent portions,

displayed and calculated.

What is the number of electrons flowing in a conductor when

the electrical charge across a given cross-section is 0.32 coulombs.

(The charge on a single electron = 1.6 x 10-19coulombs).

(Improper fractions)

(Decimal numbers)

NOTE:

In EL-W516T,

Use instead of .

6. ANGULAR UNIT

Operation Display

Angular values are converted from DEG to RAD to GRAD with each push

of the DRG►

key (2nd function of ). This function is used when doing calculations related to

trigonometric functions or coordinate geometry conversions.

Degrees (DEG is shown at the top of the display)

A commonly used unit of measure for angles. The angular measure of a circle

is expressed as 360

Radians (RAD is shown at the top of the display)

Radians are different from degrees and express angles based on the circumfer-

ence of a circle. 180

is equivalent to πradians. Therefore, the angular mea-

sure of a circle is 2πradians.

Grads (GRAD is shown at the top of the display)

Grads are a unit of angular measure used in Europe, particularly in France. An

angle of 90 degrees is equivalent to 100 grads.

The relationships between the three types

of angular units can be expressed as right:

90° (DEG) =

π/2 (RAD) =

100 (GRAD) =

Check to confirm 90 degrees equaling π/2 radians

equaling 100 grads. (π=3.14159...)

(DEG)

Turns the calculator on or clears the data. It also clears the contents of the

calculator display and voids any calculator command; however, statistics, as

well as values stored in the memory, are not erased.

Clears all internal values, including the last answer (ANS) and statistics. Values

stored in memory are not erased.

These arrow keys are useful for Multi-Line playback, which lets you

scroll through calculation steps one by one.

Turns the calculator off.

These keys are useful for editing equations. The key moves the

cursor to the left, and the key moves the cursor to the right.

The key deletes the symbol/number at the left of the cursor,

and the key deletes the symbol/number at the cursor.

Functions and Key Operations

Data Entry Keys

0 to 9

Operation

21.496 8

Display

Decimal point key. Enters a decimal point.

Numeric keys for entering data values.

Pressing this key switches to scientific notation data entry.

Provided the earth is moving around the sun in a circular orbit,

how many kilometers will it travel in a year?

Circumference equals diameter x

; therefore,

1.496 x 108x 2 x

* The average distance between the earth and the sun being

1.496 x 108km.

Enters π(3.14159...).

The constant π, used frequently in function calculations, is the ratio of the

circumference of a circle to its diameter

Enters the minus symbol.

The subtraction key is not used for entering negative numbers.

Random Key

0. *** (A random number is generated.)

[Random Dice]

To simulate a die-rolling, a random integer between 1and 6can be generated by

pressing . To generate the next random dice number, press .

[Random Coin]

To simulate a coin flip, 0(heads) or 1(tails) can be randomly generated by pressing

. To generate the next random coin number, press .

[Random Integer]

You can specify a range for the random integer with “R.Int(”.

　R.Int(minimum value, maximum value)

For example, if you enter 1 99 , a random integer from 1 to

99 will be generated. To generate the next random integer, press .

Generates random numbers.

Random numbers are three-decimal-place values between 0.000 and 0.999. Using this

function enables the user to obtain unbiased sampling data derived from random

values generated by the calculator.

APPLICATIONS:

Building sample sets for statistics or research.

NOTE:

Using LINE mode is preferable, since the numbers are generated by fractions in

W-VIEW mode. In W-VIEW mode, press to convert it to decimal form.
