Isokhethi yokuhlola i-Multimeter (ukuhlolwa kwezindlela ezi-2)

19.02.2023 /

Ingabe unayo i-analog noma i-multimeter yedijithali kodwa awazi ukuthi isetshenziswa kanjani ukuhlola indawo kagesi? Ngomhlahlandlela wethu wokuhlola izitolo nge-multimeter, uzofunda konke odinga ukukwazi. Uma ukhathazeke kakhulu ngezitolo zezintambo, sizokukhava.

Ngamafuphi, ungaphuma nge-multimeter ngokulandela lezi zinyathelo. Okokuqala, setha i-multimeter yakho ngokufanele ukuze ulinganise i-voltage. Bese uxhuma ipulaki emnyama embobeni ye-COM kanye nepulaki ebomvu embobeni ye-Omega. Bese ufaka i-probe ezindaweni ezimbili eziqondile ze-outlet kagesi. Beka elibomvu endaweni encane bese elimnyama libe endaweni enkulu. Lindela ukufundwa kwama-volts angu-110-120 ukuze uthole indawo esebenza kahle. Akukho ukufunda kusho ukuthi i-wiring yesokhethi inephutha noma i-circuit breaker ikhubekile.

Izinzuzo ze-Checkout

  • Lokhu kusiza ukugcina i-chassis ivikelekile.
  • Lokhu kuzokusiza ukuthi unqume ukuthi izintambo eziku-outlet zihlehlisiwe yini.

izinto ezidumile

Qiniseka ukuthi ufunda imanuwali yeziqondiso eze ne-multimeter yakho yedijithali noma ye-analog. Ungazithinti izikhonkwane zensimbi ukuze ugweme ukushaqeka kukagesi. Ukuhlola i-voltage endaweni kagesi kulula kakhulu. Ukuba kuyo, ungaqiniseka ukuthi umzimba wayo uphephile.

Umhlahlandlela wesinyathelo ngesinyathelo sokuhlola izitolo nge-multimeter

Sesamukele indlela yezindlela ezimbili yokuhlola ukuphuma kwe-multimeter, okungukuthi;

  • Indlela yokuqala - Ukuhlola i-voltage kusokhethi
  • Indlela yesibili - Isheke lokuqalisa i-Chassis

Asihambe khona manje.

Indlela 1: Ukuhlola i-voltage endaweni yokuphuma

1. Zijwayeze nesimo sendawo kagesi. Izisekelo zesimanje zinezikhala ezintathu - ezishisayo, ezingathathi hlangothi kanye nomhlabathi. Eliphansi liyisiyingi esiyindilinga. I-Neutral iyisikhala eside ngakwesobunxele sakho futhi okushisayo yimbobo emfishane ngakwesokunene sakho. Bamba imbobo ngayinye ngokucophelela ngoba izintambo ezintathu zingakwazi ukuphatha umsinga.

2. Faka i-analog noma i-multimeter yedijithali. Setha i-multimeter yakho ngokufanele ukuze uthole izilinganiso ze-voltage. Uyawubona umugqa wamagagasi? Lona umsebenzi wamanje oshintshanayo (AC). Ikhethe. Nansi inkomba enemininingwane eyengeziwe yokuthi ungakala kanjani i-voltage nge-multimeter.

3. Xhuma izintambo. Ipulaki yentambo kabhanana emnyama (ipulaki eliwugqinsi olufushane) kufanele lingene kujeke obhalwe ukuthi "COM". Abanye ngokuvamile banophawu lokususa eduze kwabo. Bese uxhuma isixhumi esibomvu ngophawu oluhle (+) noma i-omega, uhlamvu lwesiGreki. (2)

4. Kala i-voltage endaweni yokuphuma. Ngesandla esisodwa, faka i-probe ezindaweni ezimbili eziqondile ze-outlet kagesi. Beka elibomvu endaweni encane bese elimnyama libe endaweni enkulu. Lindela ukufundwa kwama-volts angu-110-120 ukuze uthole indawo esebenza kahle. Akukho ukufunda kusho ukuthi i-wiring yesokhethi inephutha noma i-circuit breaker ikhubekile.

Isokhethi yokuhlola i-Multimeter (ukuhlolwa kwezindlela ezi-2)

Indlela yesi-2: Qinisekisa ukuthi i-outlet isekelwe kahle 

Vumela ucingo olubomvu luhlale kusokhethi encane bese uhambisa ucingo olumnyama kusokhethi yaphansi. Ukufundwa kwe-volt akufanele kushintshe (phakathi kuka-110 no-120). Uma ukufundwa kushintshashintsha, lokhu kubonisa ukuxhumana okungalungile komhlabathi.

Ngokuhlola ukuthi i-outlet isekelwe kahle, ungaqinisekisa ukuthi i-wiring ayihlehlisiwe. Hambisa i-probe ebomvu endaweni enkulu kanye ne-probe emnyama endaweni encane. Izintambo ziyahlehliswa uma ufunda ku-DMM. Nakuba le nkinga ingase ingaphazamisi izinto ezilula zikagesi njengezibani, kungase kube inhlekelele kuma-electronics ayinkimbinkimbi.

Ukufingqa

Ukuhlola i-voltage endaweni yokuphuma, ukuthi isekelwe kahle futhi uma izintambo zihlehlisiwe, kubalulekile ukuze kuphephe ikhaya noma ihhovisi. Ngaphandle kokubandakanya unjiniyela noma osebenza ngogesi, ukukwazi ukwenza lokhu kuwukuhlanganisa. Ngenhlanhla, ungakwenza lokhu nge-analog noma i-digital multimeter.
