Hidupkan/Mati Kuasa
- Untuk menghidupkan: Tekan butang ON kunci.
- Untuk mematikan: Tekan SHIFT kemudian AC (MATI).
Pengiraan Asas
Masukkan nombor menggunakan papan kekunci berangka. Gunakan +, -, ×, dan ÷ keys for standard arithmetic operations. Press = untuk memaparkan hasilnya.
Multi-Function Keys and 2-Line Display
The calculator features a 2-line display, showing both the input expression and the result simultaneously. Many keys have multiple functions, indicated by colored labels above or below them. These functions are accessed using the SHIFT dan ALPHA kunci.
- SHIFT: Activates the yellow-labeled functions. Press SHIFT, then the desired key.
- ALPHA: Activates the red-labeled functions (variables, constants). Press ALPHA, then the desired key.
- MODE: Changes the calculator's mode (e.g., COMP, STAT, EQN). Press MODE repeatedly to cycle through options.
- CLR: Clears specific data or settings. Press SHIFT kemudian CLR to access clear options.
- DEL: Deletes the character at the cursor position.
- AC: Clears all input and returns to the initial state.
Fungsi Lanjutan
The 82Ms-A supports 240 functions, including trigonometric (sin, cos, tan), logarithmic (log, ln), power (x², x³), roots (√, ³√), fractions (a b/c), and statistical calculations. Refer to the specific key labels and their SHIFT/ALPHA functions for detailed usage.
- Fungsi Trigonometri: Gunakan dosa, cos, sawo matang keys. For inverse functions (sin⁻¹, cos⁻¹, tan⁻¹), use SHIFT with these keys.
- Fungsi Logaritma: Gunakan log (asas 10) dan ln (natural logarithm) keys.
- Fungsi Kuasa dan Akar: Gunakan x² for squaring, SHIFT kemudian x² for square root (√). For other powers and roots, use x³ or SHIFT kemudian x³ (³√).
- Pecahan: Gunakan ab/c key to input and convert fractions.
Penyelenggaraan
Pembersihan
To clean the calculator, use a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Do not use strong solvents, alcohol, or abrasive cleaners, as these can damage the casing dan paparan.
