Xa usebenza ngamaqhosha, kubalulekile ukuqonda umahluko phakathi kwemigca eqhelekileyo evulekileyo (NO) neqhele ukuvalwa (NC).Olu lwazi lunceda kwiingcingo ezichanekileyo kunye nokuqwalasela iqhosha lesicelo sakho esithile.Kule khokelo, siza kuhlolisisa iindlela zokuhlukanisa phakathi kwe-NO kunye ne-NC imigca kwiqhosha, ukuqinisekisa ukufakela kunye nokusebenza ngokuchanekileyo.
Ukuqonda iSiseko: HAYI kunye namaqhosha e-NC
Ngamagama alula, avula ngesiqhelo(NO) inabafowunelwa bayo abavulekileyo xa bengasetyenziswanga, kwaye ivala isiphaluka xa iqhosha licofa.Kwelinye icala, iswitshi eqhele ukuvalwa (NC) inabafowunelwa bayo abavaliweyo xa ingasetyenziswanga, kwaye ivula isekethe xa iqhosha licofa.
Ukuphonononga abafowunelwa beqhosha
Ukuchonga imigca ye-NO kunye ne-NC kwiqhosha, kufuneka uhlole abafowunelwa beqhosha.Jonga ngokusondeleyo kwidatadata yeqhosha okanye iinkcukacha ukumisela uqwalaselo lomfowunelwa.Umfowunelwa ngamnye uya kuba nophawu oluthile lokubonisa umsebenzi walo.
HAYI Iqhosha: Ukuchonga abafowunelwa
Kwiqhosha elithi HAYI, uya kufumana abafowunelwa ababini ababhalwe njenge "COM" (Common) kunye no "NO" (Ngesiqhelo Vula).I-terminal ye-COM ludibaniso oluqhelekileyo, ngelixa i-NO terminal ingumgca ovulelekileyo.Kwimeko yokuphumla, isiphaluka sihlala sivulekile phakathi kwe-COM kunye ne-NO.
Iqhosha le-NC: Ukuchonga abafowunelwa
Kwiqhosha le-NC, uya kufumana abafowunelwa ababini ababhalwe njenge "COM" (Common) kunye "NC" (Evalwe Ngokuqhelekileyo).I-terminal ye-COM ludibaniso oluqhelekileyo, ngelixa i-terminal ye-NC ingumgca oqhele ukuvalwa.Kwimeko yokuphumla, isekethe ihlala ivaliwe phakathi kwe-COM ne-NC.
Ukusebenzisa iMultimeter
Ukuba abafowunelwa beqhosha ababhalwanga okanye abacacanga, ungasebenzisa i-multimeter ukumisela imigca ye-NO kunye ne-NC.Seta i-multimeter kwimowudi yokuqhubeka kwaye uchukumise iiprobes kubafowunelwa beqhosha.Xa iqhosha lingacinezelwa, i-multimeter kufuneka ibonise ukuqhubeka phakathi kwe-COM kunye ne-NO okanye i-NC terminal, kuxhomekeke kuhlobo lweqhosha.
Ukuvavanya ukusebenza kweQhosha
Wakuba uchonge imigca ye-NO kunye ne-NC, kubalulekile ukuba uqinisekise ukusebenza kwayo.Qhagamshela iqhosha kwisekethe yakho kwaye uvavanye ukusebenza kwayo.Cofa iqhoshakwaye ujonge ukuba iziphatha ngokomsebenzi wayo omiselweyo (ukuvula okanye ukuvala isekethe).
Ukuqukumbela
Ukwahlula phakathi kwemigca eqhelekileyo evulekileyo (NO) kwaye ngokuqhelekileyo ivaliwe (NC) kwiqhosha ibalulekile kwiingcingo ezifanelekileyo kunye noqwalaselo.Ngokuqonda iilebula zoqhagamshelwano, ukuhlola i-database yeqhosha, okanye usebenzisa i-multimeter, unokwazi ukuchonga ngokuchanekileyo i-NO kunye ne-NC imigca.Soloko uqinisekisa ukusebenza kweqhosha emva kofakelo ukuqinisekisa ukuba lisebenza ngokulindelekileyo.Ngolu lwazi, unokusebenza ngokuzithemba ngamaqhosha kwiisekethe zakho zombane.
