Momwe mungayesere batire ndi multimeter

Batire yakufa ndi imodzi mwazovuta zomwe mwini galimoto amakumana nazo. Kuyesa kwa batire kumafunika kuti mudziwe ngati batire ikufunika kusinthidwa.

Nthawi zambiri zimakhala zovuta kudziwa vuto. Chida chotsika mtengo ngati multimeter ya digito imatha kuyesa batire ndikukuuzani ngati batire yake yagalimoto ikugwira ntchito. Ma multimeter amathanso kuyesa ma alternators, omwe angasokoneze batri yanu.

M'nkhaniyi, tidzakuthandizani kudziwa thanzi la batri pogwiritsa ntchito multimeter, komanso kuyankha mafunso otsatirawa:

• Kodi ndingadziwe bwanji ngati batire yagalimoto yanga yafa?
• Nthawi zambiri, moyo wa batri ndi wotani?
• Muzochitika ziti zomwe sizikulimbikitsidwa kugwiritsa ntchito multimeter kuyesa batire yagalimoto?

Ndi ma volts angati mu batri yagalimoto?

Pambuyo poyesa batire, mphamvu yoyenera kudutsa batire yagalimoto iyenera kukhala 12.6 volts. Chilichonse chomwe chili pansi pa 12 volts chimatengedwa ngati batire yakufa kapena yotha.

Njira zoyesera batire lagalimoto ndi multimeter

Kuyesa mabatire ndi multimeter ndi njira yosavuta komanso yoganiziridwa bwino. Zotsatira zake zikuwonetsa kuti batire lagalimoto likufunika kulipiritsidwa, kapena kuti ndi nthawi yosintha yakale.

1. Chotsani mtengo wotsalira

Siyani makina akugwira ntchito kwa ola limodzi musanayang'ane batire. Izi zikuthandizani kuti muwerenge molondola kwambiri voteji ya batire.

Ngati izi sizingatheke, yatsani nyali zamoto kwa mphindi zingapo galimoto itazimitsa. Izi zidzachotsa ndalama zotsalira zomwe magetsi a galimoto yanu angakhale nazo.

2. Konzani ma multimeter anu

Onetsetsani kuti mwapeza mtengo wolondola wa ma volts angati amagetsi batri yagalimoto yanu ingapange pokhazikitsa ma multimeter a digito ku 20 volts. Sankhani magetsi otsika kwambiri kuposa ma volts 15 pa DMM yanu ngati DMM yanu ilibe mphamvuyi.

3. Pezani batire yagalimoto

Kuti muyese batire yagalimoto, muyenera choyamba kuwonetsetsa kuti mutha kupeza batire ndi ma terminals ake. M'magalimoto ambiri, batire ili pansi pa hood mu chipinda cha injini kumbali imodzi ya injini. Komabe, pakhoza kukhala mabatire mu thunthu la magalimoto amakono. Ngati simuchipeza, mutha kulozera ku bukhu la eni galimoto yanu kapena tsamba la opanga magalimoto kuti mupeze.

Mabatire m'magalimoto amakono ali ndi chivundikiro cha pulasitiki chomwe mungafunikire kumasula kuti mupeze mabatire. Onetsetsani kuti palibe zinthu zachitsulo, monga zida, zomwe zingagwirizane ndi ma terminals, chifukwa angafupikitse.

4. Lumikizani ma multimeter amatsogolera ku ma terminals a batri.

Lumikizani chitsogozo chilichonse cha DMM ku ma terminals a batri agalimoto olakwika mpaka oyipa komanso abwino kupita ku zabwino. Onse ma multimeter ndi batri ali ndi mitundu. Ma terminal opanda pake ndi probe adzakhala akuda, ndipo positi ndi probe adzakhala ofiira. Ngati simukupeza kuwerenga kwabwino kwa DMM, muyenera kusintha.

Ngakhale ma probes ena ndi zidutswa zachitsulo zomwe zimatha kukhudzidwa, zina ndi zomangira zomwe ziyenera kumangirizidwa.

5. Onani kuwerenga

Multimeter ikuwonetsani kuwerenga. Chonde lembani. Momwemo, ngakhale mutatha kuyatsa nyali zamoto kwa mphindi ziwiri, voliyumu iyenera kukhala pafupi ndi 2 volts, mwinamwake mungakhale ndi batri yoipa. Ngati mtengo wa voteji ndi wapamwamba kwambiri kuposa 12.6 volts, ndiye kuti izi ndizabwinobwino. Batire ikatsikira ku 12.6 volts, imakhala ndi 12.2% yokha.

Chilichonse chomwe chili pansi pa 12 volts chimatchedwa chakufa kapena kutulutsidwa.

Ngakhale batire yanu ili bwino, ndikwanzeru kuyang'ana ngati galimotoyo imatha kugwiritsa ntchito mphamvu.

6. Uzani wina kuyambitsa injini

Kenako, ndi ma multimeter omwe amatsogolera ku batri yagalimoto, funsani mnzanu kuti ayatse kuyatsa kwagalimoto. Musanayambe kuyendetsa galimoto, onetsetsani kuti galimotoyo ilibe ndale ndipo mabuleki oimitsa magalimoto ali oyaka. Kuphatikiza apo, chiwongolero chilichonse cha multimeter sichiyenera kupachikidwa pa malamba osuntha kapena ma pulleys amagalimoto.

Iyi ndi ntchito ya anthu awiri; Mmodzi ayenera kuyang'anira ma oscillation a multimeter, ndipo winayo ayenera kuyang'anira kuyatsa. Yesetsani kuti musachite izi nokha, apo ayi mutha kulemba zowerengera zolakwika.

7. Yang'ananinso kuwerenga kwanu

Moyenera, pamene galimoto ikuyesera kuyambitsa, magetsi ayenera kutsika mpaka 10 volts. Ngati kuwerengera kutsika pansi pa 10 volts koma kumakhala pamwamba pa 5 volts, batire idzafa pang'onopang'ono ndipo posachedwa. Ngati igwetsa ma volts ena 5, ndi nthawi yoti musinthe.

Kupitilira apo, injini ikayamba, jenereta imatulutsa mphamvu, ndipo kuwerengera kwa batri kumayambanso kuwuka. Kuwerenga kudzabwereranso pamtengo wapamwamba wa pafupifupi 14 volts pansi pamikhalidwe yabwino. (1)

Mtengo uliwonse kunja kwa batireli ukuwonetsa batire yocheperako kapena yochulukitsidwa. Chifukwa chake, alternator iyenera kuyang'aniridwa apo ayi ingawononge batri yagalimoto yanu.

Kodi zizindikiro za batire yoyipa yagalimoto ndi chiyani?

Mutha kukumana ndi zotsatirazi zomwe zikuwonetsa batire yoyipa:

• Batire yotsika pakuwonetsa dashboard
• Dinani pa injini mukayatsa galimoto
• Kufunika kodumpha pafupipafupi
• Kuchedwa kuyatsa
• Nyali zakumutu siziyatsa, zimakhala zocheperako ndipo sizitha kupirira ntchito kwa mphindi ziwiri.

Kodi batire lagalimoto liyenera kukhala nthawi yayitali bwanji?

Mabatire ambiri amagalimoto amakhala ndi chitsimikizo cha zaka zinayi, koma sangakhale nthawi yayitali. Nthawi zambiri amatumikira zaka 3-4, pambuyo pake ayenera kusinthidwa ndi zatsopano.

Ndi liti pamene sindingagwiritse ntchito multimeter kuyesa batire yagalimoto?

Ngati mulibe mabatire osakonza, mutha kugwiritsa ntchito hydrometer kuyesa mabatire amgalimoto awa. Ngati mukufuna kuwazindikira, mabatire osasamalira amakhala ndi zipewa zapulasitiki pa selo lililonse. (2)

Chigamulo chomaliza

Simufunika thandizo la akatswiri kuti mumalize zomwe zili pamwambapa, ndipo kuyang'ana batri yanu ndi ma multimeter ndi imodzi mwa njira zosavuta komanso zotsika mtengo.
