Momwe mungagwiritsire ntchito multimeter kuyesa kutulutsa kwa 220v
Zamkatimu
Zida zamagetsi zosiyanasiyana zimafuna mphamvu zosiyanasiyana kuti zigwire ntchito.
Pazida zolemetsa m'nyumba mwanu, monga makina ochapira, mphamvu yochokera kumalo ogulitsira iyenera kukhala 220V.
Kuphatikiza apo, zida zitha kuonongeka ngati magetsi ochulukirapo agwiritsidwa ntchito. Zida zoterezi nthawi zambiri zimagwiritsa ntchito socket 120 V.
Kodi mumayesa bwanji kuchuluka kwa magetsi opangidwa ndi chotuluka kuti muwonetsetse kuti zida zanu zikuyenda bwino kapena sizikuwonongeka?
M'nkhaniyi, mupeza zonse zomwe muyenera kudziwa poyesa malo ogulitsira 220V, kuphatikiza momwe mungadziwire mwachangu ndi ma multimeter.
Tiyeni tiyambe.
Momwe mungayesere socket ya 220V ndi multimeter
Khazikitsani ma multimeter a digito ku AC voltage range pafupi ndi 220VAC ndi 240VAC, ikani kafukufuku wakuda wa multimeter mu doko losalowerera ndale ndi kafukufuku wofiira padoko lotentha. Ngati multimeter sikuwonetsa mtengo pafupi ndi 220 VAC, chotulukacho ndi cholakwika.
Pali zina zambiri zomwe muyenera kudziwa, ndipo tilowa mwatsatanetsatane tsopano.
- Samalani
Kuti mudziwe ngati chotuluka chikutulutsa mphamvu yokwanira yamagetsi, muyenera kukhala ndi madzi oyenda mumayendedwe ake.
Izi zikutanthauza kuti pali chiopsezo cha kugwedezeka kwa magetsi, ndipo ndi magetsi omwe tikulimbana nawo, njira ziyenera kuchitidwa kuti tipewe izi.
Monga kusamala, magolovesi a rabara otetezedwa ayenera kugwiritsidwa ntchito panthawiyi.
Mumapewanso ma probe achitsulo okhudzana wina ndi mzake, chifukwa izi zingayambitse dera lalifupi.
Zimalimbikitsidwanso kugwira ma probe onse ndi dzanja limodzi kuti muchepetse zotsatira za kugwedezeka kwamagetsi.
- Khazikitsani ma multimeter kukhala magetsi a AC
Zida zanu zimagwiritsa ntchito alternating current (AC voltage) ndizomwe zimayambira mnyumba mwanu zimatuluka.
Kuti mufufuze moyenera, tembenuzani kuyimba kwa multimeter kukhala voteji ya AC. Izi nthawi zambiri zimatchedwa "VAC" kapena "V~".
Komanso, popeza mukupeza 220V, onetsetsani kuti multimeter yanu yayandikira 220V (nthawi zambiri 200V).
Mwanjira iyi mudzapeza zotsatira zolondola kwambiri.
- Kupanga mawaya a multimeter
Ikani mapeto aakulu a mayesowo amatsogolera mumabowo ofanana pa multimeter.
Lumikizani waya wofiyira "zabwino" padoko lolembedwa "+" ndi waya wakuda "negative" ku cholumikizira cholembedwa "COM". Osawasokoneza.
- Ikani ma multimeter otsogolera mumabowo otuluka
Tsopano mumalumikiza ma multimeter otsogolera mumayendedwe oyenera. Monga tonse tikudziwira, zitsulo zamagulu atatu nthawi zambiri zimakhala ndi madoko otentha, osalowerera, komanso pansi.
Lowetsani chowongolera choyeserera cha multimeter mu doko lotentha kapena logwira ntchito, ndipo kuyesa koyipa kwa ma multimeter kumatsogolera ku doko losalowerera ndale.
Malo osalowerera ndale nthawi zambiri amakhala doko lalitali kumanzere kwa zotulutsa, ndipo malo otentha amakhala aafupi kumanja.
Doko la pansi ndi dzenje looneka ngati U pamwamba pa madoko ena.
Ngati mukuvutika kuzindikira madoko, nkhani yathu yamomwe mungadziwire mawaya otuluka ndi ma multimeter ikuthandizani.
Masiketi okhala ndi mapini anayi amatha kukhala ndi doko lowonjezera lokhala ngati L. Ili ndi doko lina lamtunda ndipo likhoza kunyalanyazidwa.
- Onani zotsatira za kuwerenga kwa ma multimeter
Apa ndipamene mumazindikira ngati 220 volt yanu ili bwino kapena ayi.
Mukayika bwino ma multimeter otsogolera mumabowo otuluka, mita imawonetsa kuwerenga.
Ngati mtengo uli pakati kapena pafupi kwambiri ndi 220V mpaka 240V AC, chotulukapo ndichabwino ndipo gawo lina lamagetsi likhoza kuyambitsa vutoli.
Nayi kanema yemwe angakuyendetseni poyang'ana kotuluka ndi multimeter:
Ngati mtengowo suli pafupi ndi izi, kapena ngati simuwerenga konse, zotsatira zake ndi zolakwika ndipo ziyenera kufufuzidwa mosamala.
- Kuyang'ana Mavuto
Mutha kuyesa zoyeserera zamtundu uliwonse kuti muwone chomwe chili choyipa.
Ikani kafukufuku wakuda mu doko la pansi ndikuyika kafukufuku wofiyira mu mipata ina iliyonse.
Ngati simukuyandikira 120VAC kuchokera pamipata iliyonse, ndiye kuti malowo ndi oyipa.
Njira ina yowonera chomwe chalakwika ndi chotulukapo chingakhale kuyang'ana pansi ndi multimeter.
Kuphatikiza apo, ngati multimeter ikupereka kuwerenga kolondola, mutha kulumikiza zida zamagetsi ndikuwona ngati zikugwira ntchito.
Ngati izi sizikugwira ntchito, yang'anani kuti muwone ngati mawaya omwe amatulukamo asinthidwa.
Kuti muchite izi, yang'anani ngati ma multimeter akupereka kuwerenga kolakwika mukalumikiza mawaya mu jacks zoyenera.
Mtengo woipa umatanthauza kuti wiring wasakanizidwa ndipo zipangizo sizingakhale zogwirizana nazo.
Pamenepa, musamangire zida zamagetsi m'malo opangira magetsi, chifukwa izi zitha kuwononga.
Konzani zoyenera mwamsanga ndikugwirizanitsa zipangizo kuti muwone ngati zikugwira ntchito.
Pomaliza, mutha kuyang'ana panyumba yozungulira nyumba yanu ndikuwona ngati siinagwe.
Tsatirani njira zomwezo kuyesa ma 120 volt.
Kusiyana kokha ndiko kuti m'malo moyang'ana zowerengera pafupi ndi 220 volts, mukuyang'ana zowerengera pafupi ndi 120 volts.
Pomaliza
Kuyang'ana kutulutsa kwa 220 volt ndi imodzi mwa njira zosavuta.
Mukungolumikiza ma multimeter olowera m'malo otentha komanso osalowererapo ndikuwona ngati zowerengera zili pafupi ndi 220VAC.
Pali chiopsezo cha kugwedezeka kwa magetsi, choncho onetsetsani kuti mukuchitapo kanthu.
Mafunso ofunsidwa kawirikawiri
Ndi makonda anji omwe ndiyenera kugwiritsa ntchito pa multimeter kuyesa kutulutsa?
Khazikitsani ma multimeter kukhala ma voteji a AC pafupi ndi 220 volts. Izi nthawi zambiri zimatanthawuza "VAC" kapena "V~". Multimeter yanu yakhazikitsidwa ku VAC chifukwa ndizomwe zida ndi malo ogulitsira amagwiritsa ntchito.
Kodi mungapeze kugwedezeka kwamagetsi ndi multimeter?
Inde, mutha kudabwa mukamagwiritsa ntchito multimeter kuyesa chotuluka. Izi zimachitika ngati mawaya akuwululidwa kapena ngati mukhudza zitsulo zotsogola, monga momwe ziliri pano zikuyendabe mumayendedwe otuluka.
