Ngezansi ngizokufundisa indlela yokuhlola i-fuse nge-multimeter. Udinga futhi ukubheka ngaphakathi kwe-fuse ukuze ufinyelele ekugcineni kwezinto futhi ubone ukuthi ishaywa yini. Ngizokufundisa ukuthi ungakwenza kanjani kokubili ngezansi.

Izinyathelo ezibalulekile esizodlula kuzo:

Kunikezwe i-voltage ye-fuse.
Ohm isilinganiso
Ukuhlola ama-fuse ebhokisini le-fuse
Isilinganiso sokumelana ne-fuse evuthelwe
Ihlola isimo samanje samasekhethi

Uma ufunda phakathi kuka-0 - 5 ohms (ohms), i-fuse ilungile. Noma yiliphi inani eliphakeme lisho i-fuse embi noma enesici. uma ufunda i-OL (ngaphezu komkhawulo) kusho ukuthi i-fuse eshaywayo.

Ungahlola kanjani nge-multimeter uma i-fuse ishaywa?

Kulokhu, ukuhlola ukuthi I-fuse eshaywa ukuhlolwa kwamehlo kungenzeka nje akwanele. Ngakho-ke, kufanele usebenzise i-multimeter ukuqeda konke ukungabaza.

Ukubheja kwakho okuhle ukwenza ukuhlolwa kukagesi futhi uhlole ukuthi yini engalungile ngefuse.

Okokuqala, kufanele ube nemodi yokuqhubeka ku-multimeter yakho. Iningi lama-multimeters angcono kakhulu manje linale ndlela yokusetshenziswa. Khona-ke enye ye-probes kufanele ibekwe ekupheleni kwe-fuse. Vele, enye i-probe ye-multimeter yakho kufanele futhi ibekwe ngakolunye uhlangothi lwe-fuse efanayo.
Lapha umgomo oyinhloko uwukuthola ukuthi i-fuse ilungile yini. Ngakho, kumodi eqhubekayo, i-multimeter kufanele ikhale ukuze ibonise ukuqhubeka.
Uma ungabheka ukuqhubeka, i-fuse ayishaywa. Ngamanye amazwi, lokhu kusho ukuthi akukho ukuxhumana okonakele noma okwehlisiwe.
Ngokuphambene nalokho, kungenzeka ukuthi i-multimeter ikhombisa izinga eliphezulu lokumelana ngaphandle komsindo. Ngakho-ke, uma lokhu kwenzeka, isizathu esiyinhloko ukuthi i-fuse isivele iqhume futhi ngakho-ke ayinamsebenzi.
Ungasebenzisa futhi i-multimeter ohmmeter uma ingenayo imodi yokuqhubeka. Ngakho-ke, kufanele ukhethe i-ohmmeter bese ubeka i-waveform ngayinye ekugcineni kwefuse.
Uma i-fuse iphelele, ukufundwa kwe-ohmmeter kufanele kube phansi. Ngakolunye uhlangothi, ukufundwa kuzoba phezulu kakhulu uma i-fuse ilimele noma ishaywa. (Ifuse inhle uma ukufundwa kwayo kuphakathi kuka-0 no-5 ohms (Ω).. Noma yiliphi inani eliphakeme lisho i-fuse embi noma enesici. Uma ukufunda kwakho ithi OL (Over the Limit), okusho ukuthi i-fuse eshaywayo.)

Ungahlola kanjani ukuthi i-fuse ayilungile?

Yilapho ukuhlola impilo ye-fuse kuzokuvumela ukuba ugweme izimo eziningi ezivamile ezingalindelekile. Kodwa-ke, i-fuse enhle ayitholakali ngaso sonke isikhathi, ngakho-ke kufanele ufunde ukuthi ungabheka kanjani isimo se-fuse. Ungasebenzisa i-multimeter noma ungakwazi ngokushesha ukunquma ukuthi i-fuse ishaywa ngokuphelele.

Ukuthola i-fuse eshaywayo akunzima kakhulu. Kwesinye isikhathi isixhumi se-fuse esiyinhloko siyancibilika noma siyaphuka.

Uma ungeke ukwazi ukuqinisekisa lokhu, ungaqhubeka nokusebenzisa i-multimeter. Imvamisa, lapho i-fuse eshaywayo inesixhumi esiphukile, akukho okusele okumele kwenziwe ngaphandle kokuyilungisa. Ngokuphambene, i-fuse ILUNGILE uma isixhumi sangaphakathi singancibilikisiwe. Lesi sixhumi kufanele sibe sesimweni esihle ukusuka kolunye uhlangothi lwefuse ukuya kolunye.

Ngokusobala bekungaba ngcono uma une-fuse entsha yokushintsha eshaywayo. Yiqiniso, maningi ama-fuse atholakalayo emakethe. Ngakho-ke kufanele futhi uqinisekise ukuthi i-fuse entsha iwuhlobo olufanayo nendala.

Ungahlola kanjani i-fuse futhi udlulisele nge-multimeter?

Ukuze uhlole i-fuse nge-multimeter, kufanele usebenzise imodi yokuqhubeka ku-multimeter.
Kungaba ngcono uma uxhuma i-multimeter iholela ekupheleni kwefuse ngayinye. Uma ungakwazi ukunquma ukuqhubeka ku-multimeter, i-fuse ilungile. Ngokuphambene, i-fuse eshaywayo ngaphandle uma uthola ukuqhubeka ku-multimeter yakho.
Ngakolunye uhlangothi, ungabheka ukuthi i-coil relay isesimweni esihle noma cha. Kungaba ngcono uma futhi ube ne-multimeter yedijithali enemisebenzi eyisikhombisa yalokhu.
Kulokhu, kuyadingeka ukusebenzisa imodi yokumelana phakathi kwesigxobo ngasinye se-relay. Lapha ukufundwa kufanele kube nguziro esigxotsheni esihambisanayo sabo bonke abathintwayo. (1)
Ngesikhathi esifanayo, othintana nabo kule ndawo kufanele futhi baphathwe njengokufunda kokumelana okungapheli uma ubeka ama-probe esigxotsheni esifanele. Bese ungaqhubeka ngemva kokuvula i-relay. Uzozwa ukuchofoza lapho ukudluliselwa kunikezwa amandla.
Ngemuva kwalokho kuzodingeka uphinde inqubo nge-multimeter. Lapha, ukumelana koxhumana nabo bokuvula nokuvala kufanele kube ngokwanele. Ungaphinda uhlole ukudluliselwa kwesimo esiqinile nge-multimeter. (2)
Kulokhu, udinga ukufunda i-diode ukuze uhlole lolu hlobo lwe-relay. I-multimeter izobonisa i-voltage esetshenziswe ku-relay. Ikhawunta izokhombisa uziro noma i-OL uma i-relay ingasebenzi.
Ngokuphambene, i-relay esesimweni esihle kufanele inikeze umphumela we-0.5 noma 0.7, kuye ngohlobo lwe-relay.
I-Solid state relay ngokuvamile ishibhile futhi kulula ukuyilungisa.

Sinezinye izindatshana ZOKWENZA KANJANI ongazihlola futhi ubeke uphawu ukuze uzisebenzise esikhathini esizayo. Nazi ezinye zazo: "Indlela yokushuna i-amplifier nge-multimeter" futhi "Indlela yokusebenzisa i-multimeter ukuhlola i-voltage yezintambo ezibukhoma." Sethemba ukuthi lesi sifundo sizokusiza.
