INTRODUCTION

Thank you for purchasing the SHARP Scientific Calculator
Model EL-530V. This calculator will help you understand math­ematical concepts behind fraction calculation, such as simpli­fication and reduction.
After reading this manual, store it in a convenient location for
future reference.

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
excessively humid or dusty environments.

• Since this product is not waterproof, do not use it or store it
where fluids, for example water, can splash onto it. Rain­drops, water spray, juice, coffee, steam, perspiration, etc.
will also cause malfunction.

• Clean with a soft, dry cloth. Do not use solvents or wet
cloth.

• Do not drop it or apply excessive force.

• Never dispose of batteries in a fire.

• Keep batteries out of the reach of children.

• This product, including accessories, may change due to
upgrading without prior notice.

SHARP will not be liable nor responsible for any incidental
or consequential economic or property damage caused by
misuse and/or malfunctions of this product and its periph­erals, unless such liability is acknowledged by law.

♦ Press the RESET switch (on the back), with the tip of a ball-

point pen or similar object, only in the following cases.
not use an object with a breakable or sharp tip. Note that
pressing the RESET switch erases all data stored in
memory.

• When using for the first time

• After replacing the batteries

• To clear all memory contents

• If an abnormal condition occurs and all keys are
inoperative.

If service should be required on this calculator, use only a
SHARP servicing dealer, SHARP approved service facility, or
SHARP repair service where available.

Priority Levels in Calculation

This calculator performs operations according to the following
priority:
1 Functions expressed with numerical data placed before

(such as x

2 y
3 π
4 Functions expressed with numerical data placed after (such

as sin, cos)

5 Multiplications with the sign “×” omitted from the front of a

function (such as 3cos20)

6 ×, ÷
7 +, –
8 Operations end commands (such as =, M+, %, DATA, CD)

•A parenthesized calculation section has precedence over
other sections of the calculation.

Constant Calculations

• In constant calculations, the addend becomes a constant.
Subtraction and division are performed in the same manner.
For multiplication, the multiplicand becomes a constant.

• After performing calculations using constants, on pressing
<(>) to edit an equation, the constants will be
displayed as K.

INITIAL SETUP

Mode Selection

Normal Mode:
Used to perform arithmetic operations and function calcula­tions.

Statistical Mode:
Used to perform statistical operations. To enter statistical
mode, press @”. ’ appears on the display to
indicate that the statistical mode is selected. To return to
normal mode, press @” with ’ on the display.
’ disappears as the calculator returns to normal mode.

• The mode will remain selected when the calculator is turned
off.

• When executing mode selection, last answer memory will
be cleared.

Selecting the Display Notation and Decimal
Places

This calculator has two display notation systems for displaying
calculation results: floating point system and fixed decimal
point system.

When the fixed decimal point system is selected, the number
of decimal places can be set to any value between 0 and 9.
The last decimal digit will be rounded off.

• Use @fl to switch to the fixed decimal point system,
press @i, then enter a value between 0 and 9 to set
the decimal placement.

• The number will be displayed in scientific notation if the
calculation results for floating point system does not fit in
the following range:

0.000000001 ≤ | x | ≤ 9999999999

1 ÷ 3 =
