Maitiro ekuyedza Ground neMultimeter (Matanho matanhatu)
Zviri mukati
Kune chero yemagetsi wiring system, kuvepo kwetambo yepasi kunokosha. Dzimwe nguva kusavapo kwetambo yepasi kunogona kutungamirira kumigumisiro yakaipa yedunhu rose. Ndicho chikonzero nhasi tichatarisa nzira yekutarisa pasi ne multimeter.
Sezvo mutemo, mushure mekuisa iyo multimeter kune yakanyanya voltage, iwe unogona kuisa bvunzo inotungamira kuti utarise inopisa, isina kwayakarerekera uye pasi waya uye iwo voltages. Ipapo iwe unogona kuona kana iyo yekubuda nayo yakadzikwa zvakanaka kana kuti kwete. Pazasi isu tichanyura mune izvi.
Chii chinonzi grounding?
Tisati tatanga maitiro ekuedza, tinoda kukurukura nezvekudzika. Pasina kunzwisisa kwakakodzera kwepasi, kufambira mberi hakuna maturo. Saka heino tsananguro yakapfava yegrounding.
Chinangwa chikuru chekubatanidza pasi ndechekutamisa magetsi akadzimwa kubva kune mudziyo kana chinobuda kuenda pasi. Naizvozvo, hapana achawana kuvhunduka kwemagetsi nekuda kwekubuda kwemagetsi. Yakakodzera kuchengetedza protocol ine nzvimbo yekushanda inoda waya. Unogona kushandisa nzira iyi yeimba yako kana mota. (1)
6 Nhanho Yekuyedza Iyo Ground Wire ine Multimeter
Muchikamu chino, tichakurukura nzira yekuyedza pasi ne multimeter. Zvakare, kune iyi demo, tichave tichishandisa yakajairika magetsi emumba. Chinangwa ndechekuona kana nzvimbo yekubuda nayo yakadzikwa zvakanaka. (2)
Nhanho 1 - Seta yako multimeter
Kutanga, iwe unofanirwa kumisa nemazvo iyo multimeter yekuyedza maitiro. Saka, isa multimeter yako ku AC voltage mode. Nekudaro, kana iwe uri kushandisa analog multimeter, iwe unofanirwa kuseta iyo dial kune V chinzvimbo.
Kune rimwe divi, kana uri kushandisa DMM, unofanirwa kutenderera kuburikidza nezvirongwa kusvika wawana iyo AC voltage. Kana wangoiwana, isa iyo cutoff kukosha kune yakanyanya voltage. Rangarira, kuseta voltage kune yakanyanya kuseta kunokubatsira zvakanyanya mukuwana kuverenga chaiko.
Nekudaro, mamwe ma multimeter anotumirwa pasina cutoff kukosha. Mune ino kesi, isa iyo multimeter kune AC voltage marongero uye tanga kuyedza.
Nhanho 2 - Batanidza masensa
Iyo multimeter ine maprobe maviri emavara akasiyana, tsvuku uye dema. Aya maprobe maviri anofanirwa kunge akabatana nemazvo kune multimeter's ports. Naizvozvo, batanidza iyo dzvuku bvunzo inotungamira kuchiteshi chakanyorwa V, Ω, kana +. Wobva wabatanidza probe nhema kuchiteshi chakanyorwa - kana COM. Kubatana kusiri iko kweaya ma sensors maviri uye zviteshi zvinogona kukonzera pfupi dunhu mumultimeter.
Zvakare, usashandise masensa akakuvadzwa kana akatsemuka. Zvakare, dzivirira kushandisa maprobe newaya dzisina chinhu nekuti unogona kuwana kuvhunduka kwemagetsi panguva yekuyedzwa.
Nhanho 3 - Tarisa Kuverenga Uchishandisa Active uye Neutral Ports
Iye zvino unogona kutarisa tambo yepasi ne multimeter. Panguva ino, iwe unofanirwa kuyedza iyo inopisa uye isina kwayakarerekera waya ine multimeter's test lead.
Usati waita izvi, iva nechokwadi chekubata probes kubva kune insulating wraps, izvi zvinokudzivirira kubva kune chero kukanganisa.
Wobva waisa probe dzvuku muchiteshi chinoshanda.
Tora probe nhema uye uiise mu neutral port. Kazhinji, doko diki ndiro chiteshi chinoshanda uye chiteshi chikuru ichiteshi chisina kwazvakarerekera.
“Zvisinei, kana usingakwanise kuona zviteshi, unogona kugara uchishandisa nzira yechinyakare. Budisa waya nhatu, uye ipapo nemavara akasiyana, unogona kunzwisisa zviri nyore waya.
Kazhinji waya mhenyu ishava, waya isina kwayakarerekera ibhuruu, uye waya yepasi ndeyeyero kana kuti yegirini.”
Mushure mekuisa ma probes maviri mukati meiyo mhenyu uye isina kwayakarerekera ports, tarisa iyo voltage pane iyo multimeter uye irekodhe.
Nhanho 4 - Tarisa voltage uchishandisa chiteshi chepasi
Iwe zvino unofanirwa kutarisa voltage pakati pemachiteshi mhenyu uye pasi. Kuti uite izvi, bvisa dzvuku probe kubva kune isina kwayakarerekera port uye nekunyatsoiisa muchiteshi chepasi. Usabvisa iyo dema probe kubva kune inoshanda chiteshi panguva iyi. Chiteshi chepasi igomba rakatenderera kana rakaita U-rinowanikwa pazasi kana pamusoro pekubuda.
Tarisa kuverenga kwevoltage pane multimeter uye nyora pasi. Zvino enzanisa kuverenga uku nekuverenga kwapfuura.
Kana iyo yekubuditsa yekubatanidza ikadzikwa, uchawana kuverenga kuri mukati kana mukati me5V. Zvisineyi, kana kuverenga pakati pechiteshi chengarava nepasi kuri zero kana pedyo ne zero, zvinoreva kuti kubuda hakuna kudzika.
Nhanho 5 - Enzanisa Zvese Kuverenga
Unoda kanenge katatu kuverenga kwekuenzanisa kwakakodzera. Unotova nekuverenga kuviri.
Kutanga kuverenga: Kuverenga mhenyu uye isina kwayakarerekera port
Kuverenga kechipiri: Real time port uye kuverenga pasi
Zvino tora kuverenga kubva kune kwaakarerekera port uye pasi chiteshi. Zviite:
- Isai probe dzvuku muchiteshi chisina kwazvakarerekera.
- Isai probe nhema muchiteshi chepasi.
- Nyora pasi kuverenga.
Iwe uchawana kukosha kudiki kune aya maviri madoko. Zvisinei, kana kubatanidzwa kweimba kusina kusvibiswa, hapana chikonzero chekuverenga kwechitatu.
Nhanho 6 - Verengai yakazara leakage
Kana wakapedza nhanho 3,4, 5, XNUMX uye XNUMX, iwe zvino wava nekuverenga katatu kwakasiyana. Kubva pazviverengero zvitatu izvi, verenga kudonha kwese.
Kuti uwane kubvinza kwese, bvisa kuverenga kwekutanga kubva pane yechipiri. Wobva wawedzera kuverenga kwechitatu pakuverenga kunobuda. Kana mhedzisiro yacho yakakura kupfuura 2V, unogona kunge uchishanda newaya yepasi isina kunaka. Kana mhedzisiro yacho iri pasi pe2V, socket yakachengeteka kushandisa.
Iyi inzira yakanaka yekuwana waya dzepasi dzakakanganisika.
Matambudziko ekugadzirisa magetsi emotokari
Kune chero mota, panogona kunge paine matambudziko emagetsi nekuda kwekusadzika pasi. Pamusoro pezvo, matambudziko aya anogona kuratidzira nenzira dzakawanda, seruzha muodhiyo system, matambudziko nepombi yemafuta, kana kusashanda zvakanaka kweinjini yemagetsi. Kana iwe ukakwanisa kudzivirira matambudziko aya, zvichave zvakakunakira iwe nemota yako.
Heano mamwe mazano ekudzivirira mamiriro akadai.
Ground quality point
Vazhinji vedu vanofunga kuti kana neimwe nzira waya yepasi ikasangana nemota, zvese zvinodzika. Asi ichi hachisi chokwadi. Waya yepasi inofanira kusungirirwa zvakanaka pamotokari. Semuenzaniso, sarudza poindi isina pendi uye ngura. Zvadaro batanidza.
Shandisa multimeter kutarisa pasi
Mushure mekubatanidza tambo yepasi, nguva dzose zviri nani kutarisa pasi. Saka, shandisa multimeter kune iyi maitiro. Shandisa bhatiri uye waya yepasi kuti uone voltage.
Shandisa waya dzakakura
Zvichienderana nesimba razvino, ungada kushandura ukuru hwetambo yepasi. Kazhinji, waya dzakagadzirwa nefekitari dzine 10 kusvika ku12 geji.
Pazasi pane mamwe ma multimeter ekudzidzisa madhairekitori aunogona zvakare kutarisa kunze.
- Maitiro ekushandisa multimeter kutarisa voltage yewaya mhenyu
- Maitiro ekuona iyo isina kwayakarerekera waya ine multimeter
- Maitiro ekushandisa Cen-Tech Digital Multimeter kutarisa Voltage
