Khetha indandatho yombala ngendandatho ukuze ufunde inani lokumelana, noma faka inani le-ohm ukuze uthole indandatho yombala emele; zonke izibalo ziqedwa endaweni esipheqululini.
Nquma 4, 5 noma 6 izindandatho kuqala. Ukuqala ngendandatho yamadijithi abalulekile eduze kwasekugcineni, khetha idijithi yombala ngedijithi. Indandatho yesi-4 iqukethe amadijithi amabili, iringi engu-5/6 iqukethe amadijithi amathathu; isiphetho ukubekezelelana, futhi indandatho 6 yengeza i-coefficient yokushisa. Uma isiqondiso singaqiniseki, ungasebenzisa ukuqhathanisa okuphambene. Izinhlelo ezingokomthetho kuphela ezihlehliswayo ezizobonisa imiphumela.
Isibonelo, okuphuzi, okunsomi, okuwolintshi, negolide kungu-47 kΩ, ±5%, futhi ububanzi bokubekezelela bungu-44.65–49.35 kΩ; ensundu, emnyama, emnyama, ebomvu, nensundu ngu-10 kΩ, ±1%.
Ukumelana = isibalo esisebenzayo × ukukhuliswa. Isikhawu sokubekezelelana = ukumelana okuzisholo × (1 ± iphesenti lokubekezelela). Umbuzo wokuhlehlisa ubala wonke amakhodi asekelwa yileli khasi; lapho ingakwazi ukuvezwa ngokunembile, amanani aseduze aphansi naphezulu anikezwa ngokulandelanayo, futhi ayihlungi ngochungechunge luka-E noma i-inventory.
Amakhodi anemibala ajwayelekile aqinisekiswa esidlangalaleni anikezwayo; akubandakanyi ukubekezelelana okungenambala, ukukhuliswa okuphinki nezinye izinhlanganisela ezingaqinisekisiwe, futhi ayisho ukuthi ifaka lonke isethi yamazinga e-IEC. Ayiboni izithombe, inkombandlela yokufiphala, amandla noma ukucaciswa kwengxenye.
Izinjongo zokufundisa. Hlola ngethuluzi elifanele ngemva kokunqamuka kukagesi; amasongo ombala afiphalayo noma okushisa ngokweqile angase angafundiwe kabi. Isifunda sangempela kufanele sihlolwe ku-data sheet futhi sahlulelwe ngabasebenzi abaqeqeshiwe.
Khetha inombolo yamaringi kanye nesiqondiso sombuzo. Izikwele ezinombala zilebulwe ngombhalo; okokufaka okuhlanekezelayo kwamukela amanani e-ohm ephozithivu futhi akuqinisekisi ukuthi isiphikisa esibaliwe sizoba ukumelana nokuthengeka.
