I-multimeter fuse eshaywayo (umhlahlandlela, kungani futhi ungayilungisa kanjani)
Okuqukethwe
I-DMM ilula kakhulu ukuyisebenzisa. Kodwa-ke, uma ungeyena unjiniyela kagesi noma kagesi, izinto zingase zingahambi kahle, okuyinto evamile. Asikho isidingo sokuzishaya kakhulu. Yilokhu okwenzeka ngaso sonke isikhathi. Enye yezinto ezingase zingahambi kahle nge-multimeter yakho yedijithali noma ye-analog i-fuse eshaywayo.
Ngamafuphi, uma ukala okwamanje ngokungalungile uma i-multimeter yakho isethelwe kumodi ye-amplifier, ingase ishaye i-fuse yakho. I-fuse nayo ingavuthela uma ukala i-voltage ngenkathi i-multimeter isasethelwe ukukala yamanje.
Ngakho-ke uma usola ukuthi ubhekene ne-fuse eqhunyiswayo futhi ungazi ukuthi wenzeni ngokulandelayo, ngeke uthole indawo engcono kunalapha. Lapha sizokhuluma ngakho konke okuhlobene nama-fuses ashaywa nge-multimeter.
Izinto zokuqala kuqala; Kungani ifuse ye-DMM ishaywa?
I-fuse eku-DMM iyisici sokuphepha esivimbela ukulimala kwemitha uma kwenzeka ugesi ugcwala kakhulu. I-fuse ingavuthela ngenxa yezizathu eziningana.
I-multimeter inezimbobo ezimbili zezintambo ezinhle. Imbobo eyodwa ikala i-voltage kanti enye ikala yamanje. Imbobo yokulinganisa i-voltage inokumelana okuphezulu kuyilapho imbobo yokulinganisa yamanje inokumelana okuphansi. Ngakho-ke, uma usetha iphinikhodi ukuthi isebenze njenge-voltage, izoba nokumelana okuphezulu. Ezimweni ezinjalo, i-fuse ye-multimeter yakho ngeke ivunguze, ngisho noma uyisetha ukuthi ilinganise okwamanje. Lokhu kungenxa yokuthi amandla ayancipha ngenxa yokumelana okuphezulu. (1)
Kodwa-ke, uma usetha izikhonkwane emsebenzini wamanje, kungadala ukusabela okuphambene, okuzokwenza ukuthi i-fuse iqhume. Ngenxa yalokhu, kufanele uqaphele lapho ukala i-current. Isilinganiso samanje esihambisanayo ezimweni ezimbi kakhulu singaholela ku-fuse ephephethwa ngokushesha ngoba i-ammeter inokumelana cishe neqanda.
Ukulinganisa kwamanje okungalungile akuyona into kuphela ezokwenza ukuthi i-fuse iqhume. Lokhu kungenzeka futhi uma usetha i-multimeter ukuze ulinganise amandla amanje bese uzama ukukala i-voltage. Ezimweni ezinjalo, ukumelana kuphansi, okuvumela okwamanje ukugeleza ku-multimeter yakho.
Ngamafuphi, uma ukala okwamanje ngokungalungile uma i-multimeter yakho isethelwe kumodi ye-amplifier, ingase ishaye i-fuse yakho. I-fuse nayo ingavuthela uma ukala i-voltage ngenkathi i-multimeter isasethelwe ukukala yamanje.
Ulwazi oluyisisekelo mayelana nama-multimeters edijithali
I-DMM iqukethe izingxenye ezintathu: izimbobo, isibonisi, kanye nenkinobho yokukhetha. Usebenzisa iknobhu yokukhetha ukuze usethe i-DMM ekufundweni okuhlukahlukene kokumelana, okwamanje, kanye ne-voltage. Izinhlobo eziningi zama-DMM zinezibonisi ezikhanyisiwe ukuze kuthuthukiswe ukufundeka, ikakhulukazi ezimeni zokukhanya okuphansi.
Kukhona izimbobo ezimbili ngaphambili kudivayisi.
- I-COM iyimbobo evamile exhuma phansi noma ekususeni isekethe. Imbobo ye-COM imnyama.
- 10A - Le port isetshenziswa uma kukalwa amaza aphezulu.
- I-mAVΩ iyimbobo intambo ebomvu exhumeka kuyo. Leli ichweba okufanele ulisebenzise ukukala i-current, voltage, kanye nokumelana.
Manje njengoba uyazi ukuthi yini eya lapho maqondana namachweba we-multimeter, usho kanjani uma usebenzelana ne-fuse ye-multimeter eshaywayo?
Ukutholwa kwe-fuse eshaywayo
Amafuse ashaywayo ayinkinga evamile ngama-multimeters azo zonke izinhlobo zemikhiqizo. Ngokungeziwe ekulimaleni kwemishini, amafuse aphephethiwe angabangela ukulimala. Ezimweni ezinjalo, izinga lakho lolwazi lizonquma ukuphepha kwakho nokuthi uya kanjani phambili. Imikhiqizo eminingi yama-multimeters namadivayisi ahlobene iza nezici zokuphepha ezihlaba umxhwele. Nokho, kufiseleka kakhulu ukuqonda ukulinganiselwa kwabo futhi ukwazi ukugwema izingozi ezingase zibe khona.
Ukuhlolwa kokuqhubeka kuyasiza uma udinga ukuhlola i-fuse ukuze unqume ukuthi ishaywa yini. Ukuhlolwa kokuqhubeka kubonisa ukuthi ingabe izinto ezimbili zixhumeke ngogesi. Umsinga kagesi ugeleza ngokukhululeka usuka komunye uye komunye uma kukhona ukuqhubeka. Ukushoda kokuqhubeka kusho ukuthi kukhona ikhefu endaweni ethile kusekethe. Ungase ubheke i-fuse ye-multimeter eshaywayo.
I-fuse ye-multimeter yami iqhumile - yini elandelayo?
Uma ishile, kufanele ishintshwe. Ungakhathazeki; lokhu kuyinto obungayenza wena. Kubaluleke kakhulu ukufaka i-fuse esikhundleni se-fuse enikezwa umenzi we-DMM yakho.
Landela lezi zinyathelo esikhundleni se-fuse ku-DMM;
- Thatha i-screwdriver encane bese uqala ukukhulula izikulufi ku-multimeter. Khipha ipuleti lebhethri kanye nebhethri.
- Ubona izikulufu ezimbili ngemuva kwepuleti lebhethri? Zisuse.
- Phakamisa kancane ingaphambili le-multimeter.
- Kukhona izingwegwe emaphethelweni angaphansi kwe-faceplate ye-multimeter. Faka isicelo esincane samandla ebusweni be-multimeter; shelelisela eceleni ukuze ukhulule izingwegwe.
- Ukhiphe amahhuku ngempumelelo uma ukwazi ukususa iphaneli yangaphambili yeDMM kalula. Manje usubheke ingaphakathi le-DMM yakho.
- Phakamisa ngokucophelela i-fuse ye-multimeter eshaywayo bese uyiyeka iphume.
- Shintsha i-fuse eshaywayo ufake elungile. Isibonelo, uma i-fuse ye-multimeter engu-200mA ishaywa, ukushintshwa kufanele kube ngu-200mA.
- Yilokho kuphela. Manje hlanganisa kabusha i-DMM futhi uhlole ukuthi i-fuse iyasebenza usebenzisa ukuhlolwa kokuqhubekayo ukuze uqiniseke ukuthi konke kuhamba kahle.
Ukuba nolwazi olwanele lwendlela yokusebenzisa i-multimeter kubalulekile ukuze uvimbele ama-fuse aqhunyiswayo. Naka njalo uma usebenzisa i-multimeter ukuze ugweme ukwenza amaphutha angakufaka enkingeni.
Ukufingqa
Ukuze wenze lokhu, unolwazi oluyisisekelo mayelana namachweba we-multimeter (kanye nokusetshenziswa kwawo). Uyazi futhi ukuthi kungani i-fuse ye-multimeter yakho ingase iqhume nokuthi ungayigwema kanjani. Njengoba ubonile, ukuhlola ukuqhubeka kungakusiza ukuthi uhlole i-fuse ukuze unqume ukuthi ishaywa yini. Ekugcineni, ufunde ukuthi ungayishintsha kanjani i-fuse ye-multimeter eshaywayo - into elula kakhulu. Kufanele kube yinto engenzeka esikhathini esizayo futhi sithemba ukuthi uzizwa uqiniseka ngakho ngemva kokufunda lesi sihloko. (2)
