3. Setha
3.1 Ukufakwa kwebhethri
Isibali se-Sharp EL-531WHBK sisebenza ngamabhethri amabili e-LR44, afakiwe. Ukufaka noma ukushintsha amabhethri:
- Qinisekisa ukuthi i-calculator ivuliwe VALIWE.
- Thola isembozo segumbi lebhethri ngemuva kwesibali.
- Usebenzisa i-screwdriver encane, susa ngokucophelela isikulufu esiqinisa isembozo.
- Susa isembozo bese ufaka amabhethri amabili e-LR44, uqinisekise ukuthi i-polarity (+/-) ilungile njengoba kuboniswe ngaphakathi kwegumbi.
- Shintshanisa ikhava yekhompathi yebhethri futhi uyivikele ngesikulufu.
Qaphela: Isibali siphinde sibe namandla elanga okuphila isikhathi eside kwebhethri ezimweni ezikhanyiswe kahle.
3.2 Amandla Okuqala Avuliwe
Ngemva kokufakwa kwebhethri, cindezela VULA/C ukhiye wokuvula i-calculator. Isibonisi kufanele sibonise u-"0" noma isimo sokuqala esifanayo. Uma isibonisi singenalutho noma sibonisa izinhlamvu ezingavamile, hlola kabusha ukufakwa kwebhethri noma ufake amabhethri amasha esikhundleni sawo.
4. Iziqondiso Zokusebenza
Lesi sigaba sichaza imisebenzi ehlukahlukene kanye nokusebenza kwesibali se-EL-531WHBK.
Umfanekiso 2: Ukusebenzisa i-Sharp EL-531WHBK Scientific Calculator.
4.1 Imisebenzi Eyisisekelo Yezibalo
Faka izinombolo usebenzisa ikhiphedi yezinombolo. Sebenzisa +, -, ×, futhi ÷ okhiye bokuhlanganisa, ukususa, ukuphindaphinda, kanye nokuhlukanisa, ngokulandelana. Cindezela = ukuze ubonise umphumela.
- Example: Ukuze ubale u-15 + 7: Cindezela 1 5 + 7 =. Umphumela: 22.
4.2 Imisebenzi Yesayensi
Isibali sinikeza imisebenzi eminingi yesayensi. Imisebenzi eminingi idinga ukucindezela 2ndF ukhiye wokuqala ukufinyelela imisebenzi yesibili ephrintiwe ngaphezu kwezinkinobho.
- Imisebenzi ye-Trigonometric: Sebenzisa isono, cos, i-tan. Ngemisebenzi ephambene (sin⁻¹, cos⁻¹, tan⁻¹), cindezela 2ndF bese kuba ukhiye we-trigonometric ofanele.
- Imisebenzi ye-Logarithmic: Sebenzisa log (isisekelo 10) kanye ln (i-logarithm yemvelo).
- Amandla Nezimpande: Sebenzisa x² ukuze kufakwe isikwele, √ ngempande yesikwele. Uma usebenzisa amanye amandla (xʸ) noma izimpande (ʸ√x), sebenzisa yˣ or ʸ√x imisebenzi.
- Izingxenyana: Sebenzisa i- ab/c ukhiye wokufaka kanye nokuguqula ingxenye.
4.3 Imisebenzi Yememori
Isibali sinememori ezimele (M) kanye nezinkumbulo eziyisikhombisa eziguquguqukayo (AF, X, Y).
- M+: Ingeza inani elibonisiwe kwimemori ezimele.
- M-: Isusa inani elibonisiwe kwimemori ezimele.
- I-RCL: Ikhumbula inani elivela kwimemori.
- I-STO: Igcina inani elibonisiwe kwimemori eguquguqukayo. Cindezela I-STO bese kuba ukhiye oguquguqukayo owufunayo (isb., A).
4.4 Izibalo Zezibalo
Ukuze ufake imodi yezibalo, cindezela IMODE bese ukhetha imodi yezibalo efanele (isb., STAT). Faka idatha usebenzisa I-CD YEDATHA ukhiye. Isibali singenza izibalo ezahlukahlukene zezibalo, okuhlanganisa isilinganiso, ukuphambuka okujwayelekile, kanye nokuhlaziywa kokuhlehla.
Amamodi eyunithi ye-engeli angu-4.5
Isibali sisekela izindlela ezintathu zamayunithi e-engeli: Amadigri (DEG), amaRadians (RAD), kanye namaGradians (GRAD). Cindezela DRG ukhiye ophindaphindwayo ukuze ujikeleze kulezi zindlela. Imodi yamanje ikhonjisiwe esibukweni.
5. Isondlo
5.1 Ukuhlanza
Ukuze uhlanze i-calculator, yisule kancane ngendwangu ethambile neyomile. Ungasebenzisi izihlanzi ezirhabaxa, izinyibilikisi, noma ufuthe ngqo ku-calculator.
5.2 Isitoreji
Uma ingasetshenziswa isikhathi eside, gcina i-calculator esikhwameni sayo esiqinile esivikelayo endaweni epholile, eyomile, kude nokukhanya kwelanga okuqondile kanye namazinga okushisa aphezulu.
5.3 Ukushintshwa Kwebhethri
Uma isibonisi siba lufifi noma izibalo zingaguquki, kungase kube yisikhathi sokushintsha amabhethri. Bheka isigaba 3.1 ukuthola imiyalelo yokufaka ibhethri. I-calculator isebenzisa amabhethri amabili e-LR44.
6. Ukuxazulula izinkinga
| Inkinga | Imbangela Engenzeka | Isixazululo |
|---|---|---|
