Nzira yekuedza pasi ne multimeter
Zviri mukati
Maraiti ako ari kupenya here? Muchina wako wekugeza unononoka, haushande, kana kusashanda zvachose?
Kana mhinduro yako kumibvunzo iyi iri hongu, saka kubatana kwepasi mumba mako ndicho chikonzero chinogona kuitika.
Kudzika mumba mako ndechimwe chezvinhu zvakakosha zvaunofanira kutarisira.
Kushanda kwakakodzera kwemidziyo yako yemagetsi hakuna kukosha chete, asi kunogona kuve mutsauko pakati pehupenyu nerufu.
Mugwaro iri, iwe unowana zvese zvaunoda kuziva nezve bvunzo saiti.
Ngatitangei.
Chii chinonzi grounding?
Grounding, iyo inonziwo grounding, itsika yekudzivirira mukubatanidza magetsi inoderedza njodzi kana migumisiro yemagetsi.
Nekudzika kwakakodzera, magetsi anobuda kunze kwezvitoro kana midziyo yemagetsi inotungamirirwa pasi, iyo inopera.
Pasina pasi, magetsi aya anovaka muzvitoro kana simbi dzemudziyo uye anogona kukonzera kuti midziyo isashande kana kushanda nemazvo.
Munhu akasangana nesimbi idzi dzine chaji yemagetsi kana waya dziri pachena ari panjodzi yekubatwa nemagetsi anouraya.
Grounding inotungamira iyi yakawandisa magetsi pasi uye inodzivirira zvese izvi.
Zvino iwe unonzwisisa kuti nei zvakakosha kuti zvitoro zviri mumba mako zvidzike zvakanaka.
Multimeter chishandiso chekugadzirisa matambudziko emagetsi, uye yakanaka zvakakwana kuti uedze nzvimbo dziri mumadziro ako ekubuda.
Nzira yekuedza pasi ne multimeter
Isa iyo multimeter tsvuku inotungamira mune ine simba rekubuda chiteshi, isa iyo nhema inotungamira muyasina kwayakarerekera port, uye rekodha kuverenga. Chengetedza probe dzvuku muchiteshi chinoshanda uye isa probe nhema muchiteshi chepasi. Kana kuverenga kwacho kusina kufanana nemuedzo wekare, imba yako haina kubatana kwepasi kwakakodzera..
Vanozotsanangurwa zvinotevera.
- Danho 1. Isai probes mu multimeter
Paunenge uchitarisa kugadzika padzimba dzekumba, iwe unofanirwa kuterera kuti unobatanidza sei ma probes kune multimeter.
Isa iyo dzvuku (yakanaka) bvunzo lead mumultimeter port yakanyorwa "Ω, V kana +" uye dema (negative) bvunzo inotungamira mumultimeter port yakanyorwa "COM kana -".
Sezvo iwe uchange uchiyedza waya dzinopisa, ita shuwa kuti madhairekitori ako ari muchimiro chakanaka uye haungasanganise madhiri pamultimeter kudzivirira kuikuvadza.
- Danho rechipiri: Isa iyo multimeter kune AC voltage
Zvishandiso zvako zvinomhanya pane alternating current (AC) uye sezvingatarisirwa, iyi ndiyo mhando yevoltage inobuditswa muzvitoro zvako.
Iye zvino iwe unongotendeutsa iyo multimeter dial kune AC voltage kuseta, inowanzonzi "VAC" kana "V~".
Izvi zvinokupa kuverenga chaiko.
- Nhanho 3: Kuyera voltage pakati pekushanda uye kwaakarerekera zviteshi
Isa iyo multimeter's tsvuku (yakanaka) bvunzo inotungamira mune ine simba rekubuda chiteshi uye dema (negative) bvunzo inotungamira muyasina kwayakarerekera port.
Chiteshi chinoshanda chinowanzo diki chezviteshi zviviri pane yako yekubuda, nepo isina kwayakarerekera port ndiyo yakareba kupfuura mbiri.
Chiteshi chepasi, kune rumwe rutivi, chinowanzo kuumbwa se "U".
Zviteshi pane mamwe madziro emadziro anogona kuumbwa zvakasiyana, mune iyo mamiriro ekushanda chiteshi chinowanzo ari kurudyi, isina kwayakarerekera port iri kuruboshwe, uye chiteshi chepasi chiri pamusoro.
Iko kuverenga kwemagetsi pakati pewaya yako mhenyu uye kusarerekera kwakakosha kuti kuenzanisa kuitwe gare gare.
Tora zviyero zvako uye enda kune imwe nhanho inotevera.
- Nhanho 4: Edza iyo voltage pakati pezviteshi zvepamoyo uye pasi
Zvino tora probe yako nhema kunze kweyakarerekera inobuda chiteshi woiisa muchiteshi chepasi.
Ziva kuti probe yako tsvuku inoramba iri muchiteshi chinoshanda.
Iwe zvakare uchaita shuwa kuti maprobes ari kusangana nemidziyo yesimbi mukati mezvigadziko kuitira kuti yako multimeter iverenge kuverenga.
Tora zviyero zvako uye enda kune imwe nhanho inotevera.
- Nhanho 5: Edza iyo voltage pakati pekusarerekera uye pasi zviteshi
Chimwe chiyero chaunoda kutora ndeye voltage kuverenga pakati pekusarerekera kwako uye pasi zviteshi.
Isa iyo dzvuku probe muyairerekera inobuda port, isa dema probe muvhu rechiteshi uye tora zviyero.
- Danho rechitanhatu: Ongorora zvabuda
Ino ndiyo nguva yekuenzanisa uye iwe unenge uchigadzira yakawanda yavo.
- Chekutanga, kana chinhambwe chiri pakati pebasa rako nezviteshi zvepasi chiri pedyo ne zero (0), imba yako inogona kunge isina kudzika zvakanaka.
- Kuenderera mberi, kana kuyerwa pakati pezviteshi zvako zvinoshanda uye zvisina kwazvakarerekera zvisiri mukati me5V kana zvakafanana nechiyero pakati pezviteshi zvako zvinoshanda nepasi, imba yako inogona kunge isina kudzika zvakanaka. Izvi zvinoreva kuti pamberi pevhu, kana bvunzo yechikamu uye isina kwayakarerekera ichiona 120V, chikamu uye bvunzo yepasi inotarisirwa kuona 115V kusvika 125V.
- Kungoti kana zvese izvi zvikasimbiswa, iwe uchaita imwe imwe kuenzanisa. Izvi zvinodiwa kuti utarise huwandu hwekudonha kubva pasi uye kuona kunaka kwayo.
Wana mutsauko pakati peiyo live uye isina kwayakarerekera bvunzo uye live uye pasi bvunzo.
Wedzera izvi kune zvakarerekera uye pasi bvunzo kuverenga.
Kana kuwedzera kwavo kuchipfuura 2V, saka kubatana kwako kwepasi hakusi muchimiro chakakwana uye kunofanirwa kutariswa.
Muvhidhiyo iyi tinotsanangura maitiro ese:
Imwe bvunzo iwe yaunogona kuita ine chekuita nepasi resistivity yekubatana kwako pasi.
Nekudaro, iyi inyaya yakasiyana zvachose, uye iwe unogona kutarisa yedu yakadzama chinyorwa pamusoro pekuyedza pasi kuramba nemultimeter.
Nzvimbo yekuyedza girobhu remwenje
Kuti utarise kuti imba yako yakamira sei negirobhu, unoda socket yebhora netambo mbiri.
Kara girobhu remwenje wobatanidzawo tambo pasocket yebhora.
Ikozvino ita shuwa kuti mamwe magumo etambo angangoita 3cm asina (hapana insulation) uye avhare mumhenyu uye isina kwayakarerekera inobuda ports.
Kana mwenje ukasauya, saka imba yako haina kudzika zvakanaka.
Sezvauri kuona, iyi bvunzo haina kutsanangurwa uye yakarurama seyedzo ine multimeter.
mhedziso
Kutarisa pasi mumba mako inzira iri nyore.
Zvese iwe zvunofanirwa kuita kutora zviyero pakati peakasiyana emadziro emadziro uye kuenzanisa iwo zviyero kune mumwe nemumwe.
Kana zviyero izvi zvisingaenderane kana kugara mukati memamwe matunhu, nzvimbo yemba yako yakashata.
Inowanzobvunzwa Mibvunzo
Unoziva sei kana une waya yepasi yakaipa?
Chiratidzo chimwe chete chekusadzika zvakanaka mudzimba mwenje usina kujeka kana kupenya. Mune zvimwe zviitiko, midziyo yemagetsi mumba mako inogona kusabatika kana kusashanda zvakanaka.
Iko maohm mangani inofanira kuva newaya yepasi?
Zvinotarisirwa kuti kuramba munzvimbo yako yekumba hakuzopfuure 5 ohms, nepo iyo yakanyanya kukosha iri zero (0) ohms. Iyo iri padyo kukosha kwekupikisa kune zero, zviri nani kudzika pasi.
Chii chingaitwa newaya yakasununguka?
Kudzika kwakashata kuchaita kuti magirobhu emwenje ako aite rima kana kupenya. Zvinokonzerawo kuti midziyo yemagetsi ikundikane kana kumira kushanda zvachose nekuti hapana simba rakakwana rekuishandisa.
