INTRODUCTION

Thank you for purchasing the SHARP Scientiﬁ c Calculator

Model EL-W531/W531G/W531H/W531HA/W535.

About the calculation examples (including some formulas

and tables), refer to the reverse side of this English manual.

Refer to the number on the right of each title in the

manual for use.

After reading this manual, store it in a convenient location for

future reference.

Notes:

• Some of the models described in this manual may not be

available in some countries.

• This product uses a period as a decimal point.

Operational Notes

• Do not carry the calculator around in your back pocket, as it

may break when you sit down. The display is made of glass

and is particularly fragile.

• Keep the calculator away from extreme heat such as on a

car dashboard or near a heater, and avoid exposing it to

Key Notations Used in this Manual

In this manual, key operations are described as follows:

To specify ex: @ "

To specify ln: i

To specify E: ; E

• Functions that are printed in orange above the key require

@ to be pressed ﬁ rst before the key. When you specify the

memory, press ﬁ rst. Numbers for input values are not ;

shown as keys, but as ordinary numbers.

• Functions that are printed in gray adjacent to the keys are

effective in speciﬁ c modes.

The WriteView and Line Editors

This calculator has the following two editors in NORMAL mode:

WriteView and Line. You can select between them in the SET UP

menu.

The WriteView editor (default) The Line editor

Note: In certain calculation examples, where you see the o

symbol, the key operations and calculation results are

shown as they would appear in the Line editor.

as follows:

• Angular unit: DEG

• Display notation: NORM1

• N-base: DEC

• To clear all variables and memories (A−F, M, X, Y, D1−D4, ANS,

and STAT) at once, press 1 0 .

• To RESET the calculator, press 2 0. The RESET

operation will erase all data stored in memory and restore the

calculator’s default settings.

ENTERING, DISPLAYING, AND EDITING THE EQUATION

The WriteView Editor

Entry and display

In the WriteView editor, you can

enter and display fractions or certain

functions as you would write them.

Notes:

• The WriteView editor can only be

used in NORMAL mode.

• If the equation grows too large, it may extend off the edge of the

display after you obtain the result. If you want to see the entire

equation, press or to return to the editing screen.l r

Displaying calculation results

When possible, calculation results will be displayed using

fractions, , and rπ. When you press , the display will cycle U

through the following display styles:

• Mixed fractions (with or without π) improper fractions (with 󱽔

or without π) decimal numbers󱽔

• Proper fractions (with or without

π) decimal numbers󱽔

• Irrational numbers (square roots, fractions made using square

roots) decimal numbers󱽔

Notes:

• In the following cases, calculation results may be displayed

using :r

• Arithmetic operations and memory calculations

• Trigonometric calculations

• In trigonometric calculations, when

entering values such as those in

the table to the right, results may be

shown using .r

• Calculation results may extend off

the edges of the screen. You can

see those parts by pressing l

or (depending on whether the left or right portion is r

hidden).

• Improper/proper fractions will be converted to and displayed as

decimal numbers if the number of digits used in their expression

is greater than nine. In the case of mixed fractions, the maximum

number of displayable digits (including integers) is eight.

• If the number of digits in the denominator of a fractional result

that uses π is greater than three, the result is converted to and

displayed as a decimal number.

The Line Editor

Entry and display

In the Line editor, you can enter and

display equations line by line.

Notes:

• Up to three lines of text may be

viewed on the screen at one time.

• If the length of the equation exceeds three lines, parts of it may

be hidden from view after calculation. If you want to see the

rest of the equation, press l or to return to the editing r

screen.

• In the Line editor, calculation results are displayed in decimal

form.

Editing the Equation

Just after obtaining an answer, pressing brings you to l

the end of the equation and pressing brings you to the r

beginning. Press , , , or to move the l r u d

cursor. Press or to jump the cursor to the @ l @ r

beginning or the end of the equation.

In the WriteView editor, you can use and to move the u d

cursor up and down—between the numerator and denominator,

for example.

Back space and delete key

To delete a number or function, move the cursor to the right of it,

then press . You can also delete a number or function that N

the cursor is directly over by pressing .@ y

Multi-line Playback Function 2

This calculator is equipped with a function to recall previous

equations and answers in NORMAL mode. A maximum of 340

characters can be stored in memory. When the memory is full,

stored equations will be deleted to make room, starting with the

oldest.

Pressing will display the previous equation. Further u

pressing will display preceding equations (after returning to u

the previous equation, press to view equations in order). In d

addition, can be used to jump to the oldest equation, @ u

and to jump to the newest one.@ d

• To edit an equation after recalling it, press or .l r

• The multi-line memory will be cleared by the following operations:

@ Z , mode change, RESET, N-base conversion,

angular unit conversion, editor change ( or J2 0

J P ), and memory clear ( 2 1 @ ).1 0
