Maitiro ekutsvaga waya ine multimeter (matanho matatu-gwara)

Iyi inogona kunge iri chirongwa chekuisa waya kumba, kana kutsvaga waya mumotokari yako; mune chero mamiriro ezvinhu, pasina nzira yakakodzera uye kuuraya, unogona kurasika. 

Isu tinokwanisa kuronda zviri nyore waya dzemagetsi epamba pako kana maseketi emota yako nebvunzo yekuenderera mberi. Nekuita izvi, tinoda digital multimeter. Shandisa multimeter kuona kuenderera kweimwe dunhu.

Chii chinonzi continuity test?

Heino tsananguro yakapfava kune avo vasina kujairana neshoko rekuenderera mberi mumagetsi.

Kuenderera mberi ndiyo nzira yakazara yeshinda yazvino. Mune mamwe mazwi, nekuenderera mberi bvunzo, tinogona kutarisa kuti dunhu rakavharwa here kana rakavhurika. Dunhu rinoramba riripo rine kuenderera mberi, izvo zvinoreva kuti magetsi anofamba nzira yakazara kuburikidza nedunhu iroro.

Pane zvakawanda zvinobatsira pakushandisa bvunzo dzekuenderera mberi. Heano mamwe acho.

• Iwe unogona kutarisa mamiriro efuse; zvakanaka kana kuputika.
• Inogona kutarisa kana switch inoshanda kana kwete
• Kugona kutarisa conductors; kuvhura kana kupfupika
• Inogona kutarisa dunhu; zvakajeka kana kwete.

Iyi positi ichashandisa yekuenderera bvunzo kutarisa nzira yedunhu. Ipapo tinogona kuronda waya nyore nyore.

Nzira yekugadzira multimeter kuti uedze kuenderera kwedunhu?

Kutanga, isa iyo multimeter kune ohm (ohm) kuseta. Batidza bepi. Kana iwe ukatevera matanho nemazvo, OL icharatidzwa pachiratidziri. Multimeter yako ikozvino yagadzirira bvunzo yekuenderera mberi.

Zano: OL inomirira kuti open loop. Iyo multimeter ichaverenga pamusoro zero kana bvunzo redunhu riine kuenderera. Zvikasadaro, OL icharatidzwa.

Chinangwa cheKuenderera mberi Muedzo

Kazhinji mota yako inosanganisira akawanda maseketi. Iine wiring chaiyo, maseketi aya anotakura masaini uye simba kune chimwe nechimwe chikamu mumotokari. Nekudaro, idzi waya dzemagetsi dzinogona kukuvadzwa nekufamba kwenguva nekuda kwetsaona, kushandisa zvisizvo, kana kutadza kwechikamu. Kukanganisa kwakadaro kunogona kutungamirira kudunhu rakazaruka uye pfupi pfupi.

Vhura dunhu: Iyi idiscontinuous circuit uye ikozvino kuyerera i zero. Kazhinji inoratidza kuramba kwakanyanya pakati pemapoinzi maviri.

Denderedzwa Rakavharwa: Panofanira kunge pasina kushorwa munharaunda yakavharwa. Nokudaro, ikozvino ichayerera nyore nyore.

Isu tinotarisira kuona akavhurika edunhu uye akavharwa edunhu mamiriro tichishandisa bvunzo yekuenderera tichishandisa nzira inotevera.

Mashandisiro Ekushandisa Muedzo Wekuenderera Kuziva Waya Dzakashata muMota Yako

Kune iyi yekuyedza maitiro, isu tichatarisa maitiro ekutsvaga waya ne multimeter mumotokari. Izvi zvinogona kubatsira zvakanyanya pakuona mamwe matambudziko akakomba mumotokari yako.

Zvishandiso zvinodikanwa zvekufambisa waya mudunhu

• Dhijitari multimeter
• wrench
• girazi diki
• Mwenje

Usati watanga maitiro, unofanirwa kuunganidza zvese zviri pamusoro apa. Zvino tevera matanho aya nemazvo kuronda waya.

Danho 1 - Dzima simba

Kutanga, dzima simba kune chikamu chekuyedza chemotokari yako. Haufanire kufuratira danho iri; nzira yakanaka yekuita izvi ndeyekubvisa tambo yebhatiri. Shandisa chipanera kubvisa tambo yebhatiri. Zvakare, bvisa iyo chaiyo mudziyo wemagetsi waunoronga kuyedza kubva kumagetsi.

Nhanho 2 - Tarisa zvese zvinongedzo

Kutanga, tsvaga waya dzemagetsi dzaunoda kuti uedze mukuita uku. Ita shuwa kuti waya dzese idzi dzinosvikika kuitira kuti ugone kudziedza zviri nyore nemultimeter. Zvakare, dhonza pawaya idzi kuti uedze kusimba kwenzvimbo dzekubatanidza. Mushure mezvo, tarisa kureba kwetambo dzauri kuedza. Tarisa zvakare kune waya dzakapwanyika.

Nekudaro, dzimwe nguva haugone kusvika pese pese. Saka shandisa girazi diki netochi kuti usvike panzvimbo idzi. Zvakare, unogona kuona mashoma madotsi matema pane insulation; ichi chingava chiratidzo chekupisa. Muchiitiko ichi, waya dzinoshanda nekudzivirira dzinogona kukuvara. (1)

Danho rechitatu - Tracking

Mushure mekutarisa zvese, ikozvino unogona kutsvaga waya. Tsvaga waya yekubatanidza woibvisa kuti iongororwe zvirinani. Iye zvino unogona kuongorora waya dzakakanganiswa. Wobva waisa multimeter kuti uedze kuenderera mberi.

Zvino isa imwe yea multimeter inotungamira pane simbi positi inochengetedza waya kune chinongedzo.

Zvadaro isa imwe waya pane chero chikamu chewaya. Kuzunungusa waya kana uchida kuona kubatana kwakashata. Kana iwe ukatevera maitiro nemazvo, iwe zvino uchave uine imwe inotungamira pane simbi terminal uye imwe pane waya.

Iyo multimeter inofanira kuratidza zero. Nekudaro, kana ichiratidza kumwe kuramba, idunhu rakavhurika. Izvi zvinoreva kuti waya imwe chete haisi kushanda zvakanaka uye inofanira kutsiviwa nekukurumidza. Shandisawo nzira imwechete kusvika kumagumo etambo. Ita izvi kune ese asara waya. Pakupedzisira, cherechedza chigumisiro uye uone waya dzakaputsika.

Nzira yekushandisa sei bvunzo yekuenderera mumba mako?

Izvi zvinogona kuitwa nyore kana iwe uchida kutsvaga waya panguva yeimba DIY chirongwa. Tevera matanho aya.

Zvishandiso zvinodiwa: Digital multimeter, waya refu, mamwe lever nzungu.

1 Step: Fungidzira kuti iwe unoda kuyedza kubatana kubva kune imwe nzvimbo kuenda kune imwe (funga mapoinzi A uye B). Hatikwanise kuziva kuti iwaya ipi nekuitarisa. Saka, tinodhonza waya dzinoda kuongororwa. Semuenzaniso, iwe unofanirwa waya mapoinzi A uye B.

2 Step: Batanidza tambo refu kune imwe socket waya (point A). Shandisa lever nut kuchengetedza waya. Wobva wabatanidza imwe magumo etambo refu kune multimeter's black wire.

3 Step: Zvino enda kunongedzo B. Ikoko unogona kuona zvakawanda zvakasiyana waya. Seta iyo multimeter kuti uedze kuenderera mberi. Woisa waya tsvuku pane imwe neimwe yewaya idzodzo. Waya inotaridza kuramba pamultimeter panguva yebvunzo yakabatana nepoinzi A. Kana dzimwe waya dzisingaratidzi kuramba, waya idzodzo hadzina kubatanidza kubva pamapoinzi A kusvika kuB.

Summing up

Nhasi takakurukura kutsvaga waya ine multimeter mumamiriro akasiyana. Isu tinoshandisa bvunzo yekuenderera kuteedzera waya mune ese ari maviri mamiriro. Tinovimba iwe unonzwisisa nzira yekutevera waya ne multimeter mumamiriro ese. (2)

Pazasi pane mamwe maitirwo-emadhairekitori emamultimeter aunogona kuongorora uye kuongorora gare gare. Kusvikira chinyorwa chedu chinotevera!
