Instalacja baterii

The Sharp EL-531TGBBW calculator operates on Twin Power (solar and battery). One AAA battery is included. To install or replace the battery:

1. Upewnij się, że kalkulator jest wyłączony.
2. Znajdź pokrywę komory baterii z tyłu kalkulatora.
3. Carefully slide or unscrew the cover to open it.
4. Insert the AAA battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
5. Dokładnie załóż pokrywę komory baterii.

Pierwsze włączenie zasilania

Naciśnij WŁ./C key to turn on the calculator. The display should show '0' or a previous calculation result. If the display is dim or blank, ensure the battery is correctly installed and that there is sufficient light for the solar panel.

Display and Direct Algebraic Logic (D.A.L.)

The calculator features a 2-line LCD display, showing both the calculation entry and the result simultaneously. The Logika algebraiczna bezpośrednia (DAL) system allows you to input elements of an expression in the exact order they appear when written, simplifying complex calculations.

Podstawowe operacje

• Dodawanie, odejmowanie, mnożenie, dzielenie: Wprowadź liczby i użyj +, -, ×, ÷ Klucze. Naciskać = dla wyniku.
• Wyczyść wejście/Wszystko jasne: Naciskać WŁ./C Naciśnij raz, aby wyczyścić bieżący wpis. Naciśnij dwukrotnie, aby wyczyścić wszystkie obliczenia i pamięć (z wyjątkiem pamięci niezależnej).

Funkcje naukowe (273 funkcji)

The calculator supports a wide range of scientific functions. Many keys have secondary functions, accessed by pressing the 2 piętro key first, then the desired function key.

• Funkcje trygonometryczne: grzech, sałata, dębnik i ich funkcje odwrotne (arc sin, arc cos, arc tan).
• Funkcje logarytmiczne: dziennik (common logarithm), ln (logarytm naturalny).
• Moce i korzenie: x², √, yˣ.
• Factorials: n!
• Reciprocals: 1/x
• Funkcje hiperboliczne: hipnoza (hyperbolic sine, cosine, tangent).

Funkcje pamięci

The calculator includes eight temporary memories, one independent memory (M+, M-, RCL M), and one last answer memory (ODP.).

• STO (Store): Stores a value into a variable (A-F, X, Y).
• RCL (Recall): Recalls a value from a variable.
• M+ / M-: Adds/subtracts the displayed value to/from the independent memory.
• ODP.: Przywołuje wynik poprzedniego obliczenia.

Funkcje statystyczne

The calculator supports 1-variable and 2-variable statistics, along with six regression types.

1. Naciskać TRYB wybrać STAT tryb.
2. Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
3. Enter data using the Płyta CD z danymi klawisz.
4. Perform calculations using the statistical function keys.

N-Base Calculations

Perform calculations in Hexadecimal (KLĄTWA), Binary (KOSZ), Decimal (GRUDZIEŃ), Octal (PAŹDZIERNIK), and Pentadecimal (PIÓRO) bases.

• Use the dedicated keys for base conversions (e.g., →HEX, →BIN).
• Logical operations like AND, OR, NOT, XOR, and XNOR are also available.

Equation Editing & Playback

The calculator allows for editing previously entered equations and multi-line playback. Use the arrow keys to navigate through entries and make corrections.

Klucz do domu

Ten DOM key allows users to return to the initial calculation screen, clearing any previously entered data or settings without turning off the calculator.

Konserwacja

Czyszczenie

To clean the calculator, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator. Avoid excessive moisture.

Protective Hard Cover

The calculator comes with a protective hard cover. Always use this cover when the calculator is not in use to prevent scratches, dust accumulation, and accidental damage to the display and keys.

Źródło zasilania

The EL-531TGBBW utilizes Twin Power, meaning it operates on both solar energy and a AAA battery. Ensure the solar panel is exposed to light for optimal performance and to extend battery life. Replace the AAA battery when the display becomes dim or unresponsive in low light conditions.

Rozwiązywanie problemów

• Wyświetlacz jest pusty lub przyciemniony: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
• Nieprawidłowe wyniki obliczeń: Verify the input sequence and selected mode (e.g., DEG/RAD/GRAD, Normal/STAT). Press NASTAWIĆ (located on the back, may require a thin object like a paperclip) to return the calculator to its default settings. Note that resetting will clear all memory contents.
• Kalkulator nie reaguje na naciśnięcia klawiszy: Ensure the calculator is turned on. If it remains unresponsive, try removing and reinserting the battery, or perform a reset.
