3. Nastavitev
3.1 vir energije
The Sharp EL-W531 calculator operates using both solar power and a single AAA battery. The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions.
3.2 Namestitev/zamenjava baterije
- Prepričajte se, da je kalkulator izklopljen.
- Poiščite pokrovček predalčka za baterije na zadnji strani kalkulatorja.
- Z majhnim izvijačem previdno odstranite vijak, s katerim je pritrjen pokrov.
- Snemite pokrov.
- Remove the old AAA battery (if applicable) and insert a new AAA battery, ensuring correct polarity (+/-).
- Ponovno namestite pokrov prostora za baterije in ga pritrdite z vijakom.
3.3 Začetni vklop
Pritisnite VKLOP/C button to turn on the calculator. The display will show the last calculation or be cleared, depending on the previous state.
4. Navodila za uporabo
4.1 Osnovni izračuni
Za izvajanje osnovnih aritmetičnih operacij:
- Vnesite prvo številko.
- Pritisnite želeno tipko za upravljanje (+, -, ×, ÷).
- Vnesite drugo številko.
- Pritisnite = za prikaz rezultata.
4.2 PišiteView Zaslon
The WriteView zaslon vam omogoča vnos in view mathematical expressions as they appear in textbooks. Fractions, roots, and other complex expressions are displayed in a natural format. Use the navigation keys (up, down, left, right arrows) to move the cursor within an expression for editing.
4.3 Function Modes
The calculator offers various modes for different types of calculations. Press the NAČIN key to cycle through available modes such as:
- NORMALNO: For general arithmetic and function calculations.
- STATISTIKA: For statistical calculations.
- EQN: For solving equations.
Refer to the on-screen indicators (e.g., DEG, RAD, GRAD) for the current angle unit. Press DRG► (dostopno prek 2. F) to change the angle unit.
4.4 Znanstvene funkcije
The EL-W531 includes 335 functions. Many functions are accessed directly, while others require pressing the 2. F key first. Common functions include:
- Trigonometric: sin, cos, tan in njihove inverzne funkcije (sin-1, cos-1, torej-1).
- Logarithmic/Exponential: log, ln, 10xex.
- Power/Root: x2, √, xy, y√x.
- ulomki: a b/c key for mixed numbers and improper fractions.
- Pomnilnik: STO (store), RCL (recall), M+ (memory plus).
Consult the key labels and the calculator's display for specific function usage.
5. Vzdrževanje
5.1 Čiščenje
Kalkulator očistite tako, da ga nežno obrišete z mehko, suho krpo. Ne uporabljajte abrazivnih čistil, topil ali mokrih krp, saj lahko poškodujejo kalkulator.asing ali notranjih komponent.
5.2 Shranjevanje
Store the calculator in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. If storing for an extended period, it is advisable to remove the battery to prevent leakage.
5.3 Skrb za baterije
Replace the AAA battery promptly when the display becomes dim or erratic. Dispose of used batteries according to local regulations.
6. Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Kalkulator se ne vklopi. | Low or dead battery; insufficient light for solar panel. | Replace the AAA battery. Ensure adequate lighting for the solar panel. |
| Zaslon je zatemnjen ali prazen. | Low battery; insufficient light. | Replace the AAA battery. Move to a brighter area. |
| Napačni rezultati izračuna. | Incorrect mode setting; input error; memory error. | Check the current mode (e.g., DEG/RAD). Clear all memory (2. F M-CLR). Re-enter the calculation carefully. |
| Prikazano je sporočilo »NAPAKA«. | Mathematical error (e.g., division by zero, invalid input). | Pritisnite VKLOP/C to clear the error. Review your input and the mathematical operation. |
