Isivivinyo Sokumelana Nokuphezulu se-YY321B
Hlola ukumelana kwendwangu kusukela ephuzwini kuya ephuzwini.
I-GB 12014-2009
1. Yamukela isibonisi sedijithali esinezinombolo ezintathu nengxenye, isekethe yokulinganisa ibhuloho, ukunemba okuphezulu kokulinganisa, ukufunda okulula nokunembile.
2. Isakhiwo esiphathekayo, usayizi omncane, isisindo esilula, kulula ukusisebenzisa
3. Ingasebenza ngebhethri, ithuluzi lingasebenza esimweni sokumiswa komhlaba, hhayi nje kuphela ukuthuthukisa ikhono lokulwa nokuphazamiseka nokususa ukunakekelwa kwentambo kagesi, lingasetshenziswa futhi ngezikhathi ezithile ukunikezwa kwamandla okulawula i-voltage yangaphandle.
4. Isibali sikhathi esakhelwe ngaphakathi, ukukhiya okuzenzakalelayo kokufunda, isivivinyo esilula
5. Ibanga lokulinganisa ukumelana lifinyelela ku-0 ~ 2×1013Ω, ikhono lokulinganisa ukumelana lamanje ukusuka ephuzwini kuya ephuzwini liyithuluzi ledijithali eliqinile. Liyithuluzi elihle kakhulu lokulinganisa ukumelana kwevolumu kanye nokumelana kobuso bezinto zokufaka umswakama. Isixazululo esiphezulu kakhulu yi-100Ω.
6. Izinhlobo ezine ze-voltage yokukhipha (10,50,100,500), ezifanele zonke izinhlobo zokuhlolwa kokumelana nezinto zokugqoka.
7. Ibhethri elishajekayo elakhelwe ngaphakathi elisebenza kahle kakhulu, gwema inkinga yokushintsha ibhethri, wonge izindleko zokushintsha ibhethri.
8. Isixhumi sokusebenza esenziwe umuntu. Isikrini esikhulu, isikrini se-LCD esikhanya kakhulu, ngaphezu kwesibonisi semiphumela yokulinganisa, kukhona isibonisi somsebenzi wokulinganisa, isibonisi se-voltage yokukhipha, isibonisi seyunithi yokulinganisa, isibonisi sesikwele esiphindaphindayo, isibonisi se-alamu ye-voltage ephansi yebhethri, isibonisi se-alamu yokungasebenzi kahle, lonke ulwazi ngokushesha.
1. Isilinganiso sokumelana: 0 ~ 2×1013 (Ω)
2. Isibonisi: Isikrini esikhulu esingamadijithi angu-3 1/2 esinesibonisi sedijithali esikhanyayo ngemuva
3. Isikhathi sokulinganisa: 1min ~ 7min
4. Iphutha eliyisisekelo lokulinganisa ukumelana:
5. Isixazululo: isibonisi sensimbi kububanzi ngabunye singazinza. Funda inani elincane lenani lokumelana elihambisanayo kufanele libe ngaphansi noma lilingane nephutha elivumelekile lebanga elingu-1/10.
6. Iphutha le-voltage yenkinobho yokugcina: iphutha le-voltage yenkinobho yokugcina yensimbi alidluli ku-± 3% wenani elilinganiselwe
7. Okuqukethwe kwe-voltage yenkinobho yokuphela: inani lesikwele eliphakathi kwempande lokuqukethwe kwe-voltage yenkinobho yokuphela kwensimbi akudluli ku-0.3% wengxenye ye-DC.
8. Iphutha lesikhathi sokulinganisa: iphutha lesikhathi sokulinganisa lethuluzi alidluli ku-±5% wenani elibekiwe.
9. Ukusetshenziswa kwamandla: ibhethri eyakhelwe ngaphakathi ingasebenza ngokuqhubekayo amahora angama-30. Ukusetshenziswa kwamandla kwamandla kagesi angaphandle kungaphansi kwama-60mA.
10. Ukunikezwa kwamandla: i-voltage ekalwe (V): DC 10, 50, 100, 500
Ukunikezwa kwamandla: Amandla ebhethri le-DC 8.5 ~ 12.5V
