Navodila za uporabo

This section details the basic operation and function usage of your Sharp EL-W531TL scientific calculator.

Osnovne aritmetične operacije

Perform standard addition, subtraction, multiplication, and division using the dedicated keys (+, -, ×, ÷).

• Enter numbers and operators sequentially. Press the = tipko za prikaz rezultata.

Example: To calculate 15 + 7:

Pritisnite 1, 5, +, 7, =. Na zaslonu se bo prikazalo 22.

Function Access (2nd F Key)

Many keys have secondary functions printed above them. To access these functions, press the 2. F key first, then the desired function key. The "2nd F" indicator will appear on the display.

Example: To calculate sin(30):

1. Ensure the calculator is in STOP mode (see Display Modes).
2. Pritisnite 2. F, potem greh (which is the primary function of the key).
3. Vnesite 3, 0, nato pritisnite =. Na zaslonu se bo prikazalo 0.5.

PišiteView Zaslon

The WriteView feature allows you to input and display equations in a natural, textbook-like format.

• Enter equations as they appear in your textbook. The calculator will display fractions, roots, and other expressions clearly.
• Use the arrow keys (left, right, up, down) to navigate within an equation for editing.

Display Modes (DEG, RAD, GRAD)

The calculator supports three angle modes: Degrees (STOP), radiani (RAD) in Gradianci (GRAD).

• To change the mode, press the NAČIN key repeatedly until the desired mode (STOP, RAD, oz GRAD) is highlighted or selected.
• The current angle mode is indicated on the display.

Pomnilniške funkcije

The calculator includes memory functions to store and recall values.

• M+ (Memory Plus): Adds the displayed value to the independent memory.
• M- (Memory Minus): Subtracts the displayed value from the independent memory.
• RCL (Recall Memory): Recalls the value stored in the independent memory.
• STO (Store Memory): Stores the displayed value into a specific variable memory (A, B, C, D, E, F, X, Y, M).

Fractions and Decimals

• To enter a fraction, use the ab/c ključ.
• To convert a fraction to a decimal or vice versa, press the 2. F tipki, ki ji sledi ab/c ključ.

Statistične funkcije

The calculator includes various statistical functions.

• Za vstop STAT način, pritisnite NAČIN tipko do STAT je izbrana.
• Input data points and use the statistical function keys (e.g., mean, standard deviation) to perform calculations.
• Refer to the detailed function guide for specific statistical operations.

Vzdrževanje

Pravilno vzdrževanje zagotavlja dolgo življenjsko dobo in optimalno delovanje vašega kalkulatorja.

Čiščenje

• Zunanjost kalkulatorja obrišite z mehko, suho krpo.
