Mokhoa oa ho lekola betri ka multimeter

Betri e shoeleng ke e 'ngoe ea mathata a tloaelehileng ao mong'a koloi a tobanang le 'ona. Teko ea betri ea hlokahala ho etsa qeto ea hore na betri e hloka ho khutlisoa.

Hangata ho thata ho fumana bothata. Sesebelisoa se theko e tlaase joalo ka multimeter ea dijithale se ka leka betri mme sa u joetsa hore na betri ea koloi ea eona e tšoere tefiso. Multimeter e ka boela ea leka li-alternator, tse ka amang betri ea hau hampe.

Sehloohong sena, re tla u thusa ho tseba bophelo ba betri ka multimeter, hammoho le ho araba lipotso tse latelang:

• Ke tseba joang haeba betri ea koloi ea ka e felile?
• Ka kakaretso, bophelo ba betri ke bofe?
• Ke maemong afe moo ho sa khothaletsoang ho sebelisa multimeter ho lekola betri ea koloi?

Ke li-volts tse kae ka betri ea koloi?

Ka mor'a ho lekola betri, matla a loketseng ho feta betri ea koloi e lokela ho ba 12.6 volts. Ntho leha e le efe e ka tlase ho 12 volts e nkoa e le betri e shoeleng kapa e senyehileng.

Mehato ea ho lekola betri ea koloi ka multimeter

Ho etsa liteko tsa libeteri ka multimeter ke mokhoa o batlang o le bonolo ebile o nahanisisitsoe hantle. Sephetho se bontša hore betri ea koloi e hloka ho tjhaja, kapa hore ke nako ea ho khutlisa ea khale.

1. Tlosa tefiso e setseng

Tlohela mochine o sebetsa bonyane hora pele o hlahloba betri. Sena se tla u thusa ho fumana 'malo o nepahetseng ka ho fetesisa oa matla a betri.

Haeba sena se sa khonehe, khantša mabone ka metsotso e seng mekae koloi e koetsoe. Sena se tla felisa tefiso efe kapa efe e setseng eo sistimi ea motlakase ea koloi ea hau e ka bang le eona.

2. Lokisetsa multimeter ea hau

Etsa bonnete ba hore u fumana boleng bo nepahetseng ba hore na betri ea koloi ea hau e ka hlahisa li-volts tse kae tsa motlakase ka ho beha multimeter ea digital ho 20 volts. Khetha motlakase o tlase ho feta 15 volts ho DMM ea hau haeba DMM ea hau e se na motlakase ona.

3. Fumana betri ea koloi

Ho lekola betri ea koloi, u lokela ho qala ka ho etsa bonnete ba hore u ka fumana betri le li-terminals tsa eona. Likoloi tse ngata, betri e ka tlas'a sekoti ka kamoreng ea enjene ka lehlakoreng le leng la enjene. Leha ho le joalo, ho ka 'na ha e-ba le libeteri ka kutu ea likoloi tsa kajeno. Haeba u sa e fumane, u ka sheba buka ea litaelo ea mong'a koloi ea hau kapa webosaete ea moetsi oa likoloi ho e fumana.

Libetri tsa likoloi tsa sejoale-joale li na le sekoaelo sa polasetiki seo u ka tlamehang ho se qhaqha hore u fihlele liteishene tsa betri. Etsa bonnete ba hore ha ho na lintho tsa tšepe, joalo ka lisebelisoa, tse kopanang le li-terminals, kaha li ka khutsufatsa.

4. Hokela multimeter ho isa litsing tsa betri.

Hokela e 'ngoe le e 'ngoe ea DMM ho liteishene tsa betri tsa koloi tse mpe ho isa ho tse mpe le tse ntle ho isa ho tse ntle. Ka bobeli multimeter le betri li na le mebala-bala. Thenegative terminal le probe li tla ba ntšo, 'me theminale e nepahetseng le probe li tla ba khubelu. Haeba u sa fumane 'malo o nepahetseng oa DMM, u lokela ho o khutlisetsa morao.

Le hoja lisebelisoa tse ling e le likotoana tsa tšepe tse ka angoang, tse ling ke li-clamp tse lokelang ho hokelloa.

5. Hlahloba ho bala

Multimeter e tla u bontša ho bala. Ke kopa o e ngole fatshe. Ha e le hantle, esita le ka mor'a ho khantša mabone ka metsotso e 2, motlakase o lokela ho ba haufi le 12.6 volts, ho seng joalo u ka ba le betri e mpe. Haeba boleng ba motlakase bo phahame hanyenyane ho feta 12.6 volts, joale sena se tloaelehile ka ho feletseng. Haeba betri e theohela ho 12.2 volts, e tla lefisoa 50% feela.

Ntho efe kapa efe e ka tlase ho li-volts tse 12 e bitsoa e shoeleng kapa e lokollotsoe.

Esita le haeba betri ea hao e tjhajiloe hantle, ke bohlale ho hlahloba hore na koloi e ka khona ho sebelisa matla ka katleho.

6. E-re motho a qale enjene

Ka mor'a moo, ka lisebelisoa tsa multimeter tse khomaretsoeng betereng ea koloi, kopa motsoalle ho bulela mollo oa koloi. Pele o qala koloi, etsa bonnete ba hore koloi ha e nke lehlakore 'me mariki a ho paka a ntse a le teng. Ntle le moo, lead efe kapa efe ea multimeter ha ea tlameha ho leketla mabanta a tsamaeang kapa li-pulley tsa motor.

Ona ke mosebetsi oa batho ba babeli; e mong o lokela ho beha leihlo ho oscillation ea multimeter, 'me e mong o lokela ho laola ho khantša. Leka ho se etse sena sohle ka bouena, ho seng joalo u ka rekota lipalo tse fosahetseng.

7. Sheba 'malo oa hau hape

Ha e le hantle, ha koloi e leka ho qala, motlakase o lokela ho theohela ho 10 volts. Haeba 'malo o theoha ka tlase ho li-volts tse 10 empa o lula ka holim'a 5 volts, betri e tla shoa butle mme haufinyane e tla shoa. Haeba e theola li-volts tse ling tse 5, ke nako ea ho fetoha.

Ho feta moo, ha enjene e qala, jenereithara e tla fana ka hona joale, 'me lipalo tsa betri li tla qala ho phahama hape. Ho bala ho tla khutlela ho boleng bo phahameng ba hoo e ka bang 14 volts tlas'a maemo a loketseng. (1)

Boleng bofe kapa bofe bo ka ntle ho sebaka sena bo bonts'a betri e sa tjhajeng kapa e tjhajeng ho feta tekano. Kahoo, alternator e tlameha ho hlahlojoa ho seng joalo e tla senya betri ea koloi ea hau.

Matšoao a betri e mpe ea koloi ke afe?

U kanna ua ba le mathata a latelang a bonts'ang betri e mpe:

• Betri e tlase e bonts'a dashboard
• Tobetsa enjine ha o bulela koloi
• Tlhokahalo ea ho qhoma khafetsa
• Ho lieha ho hotetsa
• Mabone a hlooho ha a lumelloe, a lerootho 'me ha a khone ho mamella ts'ebetso ka metsotso e 2.

Betri ea koloi e lokela ho sebetsa nako e kae?

Libetri tse ngata tsa koloi li na le waranti ea lilemo tse 'nè, empa li ka' na tsa se ke tsa tšoarella nako e telele hakaalo. Hangata ba sebeletsa lilemo tse 3-4, ka mor'a moo ba tlameha ho nkeloa sebaka ke tse ncha.

Ha ke khone ho sebelisa multimeter ho lekola betri ea koloi?

Haeba u sena libeteri tse sa hlokeng tlhokomelo, u ka sebelisa hydrometer ho lekola libeteri tsena tsa koloi. Haeba u batla ho li tseba, libeteri tse sa hlokeng tlhokomelo li na le likatiba tsa polasetiki seleng ka 'ngoe. (2)

Qeto ea ho qetela

Ha u hloke thuso ea litsebi ho phethela mehato e kaholimo, 'me ho lekola betri ea hau ka multimeter ke e' ngoe ea litsela tse bonolo le tse theko e tlaase.
