Momwe Mungayesere Nyali za Kalavani ndi Multimeter (Guide)

Ndikofunika kwambiri kuti kuyatsa kalavani yanu kumagwira ntchito bwino. Kuyendetsa galimoto popanda iwo kumaika pangozi moyo wanu ndi wa ena. Komabe, ngakhale mutawasamalira, nthawi zambiri amasiya kugwira ntchito.

Pansipa taphatikiza kalozera wamomwe mungayesere nyali za ngolo ndi multimeter. Izi zidzakuthandizani kupewa zolakwika zamtsogolo ndikupangitsa kuti ntchitoyi ichitike molondola.

Chifukwa chiyani kuwala kwa ngolo sikukugwira ntchito?

Kuyika kwapansi kolakwika kumayambitsa mavuto ambiri opangira ma waya. Nthawi zambiri waya woyera amatuluka cholumikizira ngolo. Magetsi amatha kugwira ntchito pafupipafupi kapena osagwira ntchito konse ngati nthaka ili yoyipa.

Ngakhale mawaya a socket ndi abwino, yang'anani pansi pa chimango cha ngolo. Iyenera kukhala yonyezimira ndi yoyera, yopanda utoto ndi dzimbiri, komanso yokhazikika. Ngati mukugwiritsa ntchito siginecha imodzi ndipo yayatsidwa koma osawala momwe imayenera kukhalira, ganizirani kuti ndi malo oti mukayikire.

Momwe mungayesere nyali za trailer ndi multimeter

Nthawi zambiri, kuwonekera kwa kalavani kumatope, chipale chofewa, mvula, dzuwa, ndi mchenga kumatha kuwononga kuyatsa kwa kalavaniyo, chifukwa izi zimapangitsa kuti pakhale zovuta zosiyanasiyana. Chifukwa chake, nthawi zonse muyenera kuyang'ana ngati nyali za ngolo yanu zikuyenda bwino. 

Nambala 1. kuyezetsa matenda

Musanatulutse multimeter, yang'anani vuto ndi maulumikizidwe, osati china. Kodi kuchita izo? 

• Bwezerani mababu poyamba, chifukwa izi zikhoza kukhala gwero la vuto, osati nyali zamoto.
• Ngati sichikugwirabe ntchito, vuto likhoza kukhala ndi waya.
• Chotsani zingwe zomwe zimagwirizanitsa galimoto yaikulu ku ngolo. 
• Ikani magetsi akutsogolo ku kalavani kuti muyese izi.
• Ngati zizindikiro sizikugwirabe ntchito, muyenera kugwiritsa ntchito multimeter.

#2 Ground Test

Tsopano muyenera kuyang'ana pansi ndi multimeter.

• Gwirani njira ziwiri za multimeter, zakuda ndi zofiira kapena zoipa ndi zabwino motsatana.
• Kuti muwone kukhazikika, multimeter iyenera kukhazikitsidwa ku ohms kapena kukana.
• Lumikizani masensa kuti muwonetsetse kuti akugwira ntchito.
• Lumikizani kafukufuku wofiyira pansi ndikusaka kwakuda ku terminal yoyipa. Ma multimeter ayenera kuwerenga pafupifupi 0.3 ohms.

Nambala 3. Mayeso a trailer plugs

Pambuyo powunika nthaka ndikuzindikira kuti ili si vuto, muyenera kupitiliza kuyang'ana pulagi ya ngolo. Izi ndizofunikira kuti zitsimikizire kuti magetsi ofunikira akupezeka. Komanso, onetsetsani kuti mwamvetsetsa cholumikizira chanu ndi mawaya onse kuti musasokonezeke. Kuchita zimenezi kungachititse ngozi kapena kuchitidwa opaleshoni yolakwika. Kumbali ina, ma multimeters nthawi zambiri amalembedwa, pomwe ena amakhala ndi mitundu yosiyana. (1)

Kuyesa pulagi ya trailer.

• Khazikitsani ma multimeter kukhala ma volts a Direct current (DC) ndikulumikiza ku lead negative lead. 
• Lumikizani waya wakutsogolo ku terminal yabwino ndikuyatsa nyali yoyendetsedwa ndi piniyo.
• Ngati multimeter ikuwonetsa kuchuluka kwa ma volt monga pulagi ikuyesedwa, pulagiyo si gwero la vuto.

Mwachitsanzo, ngati mumangiriza probe yanu yofiyira kumanja kwa cholumikizira chamanzere, muyenera kuyatsa kuwala kwake. Zotsatira zake, multimeter yanu iwonetsa pafupifupi 12 volts. Ngati ipitiliza kuwonetsa izi mutayesanso, zikutanthauza kuti mapulagi a trailer spark akugwira ntchito bwino.

Nambala 4. Mayeso a Voltage

Uku ndikuwunika mphamvu yamagetsi ngati simunapeze vuto kale.

• Yang'anani kulumikizana kwanu kuti muwone mawaya omwe amapita ku kuwala. Monga lamulo, pali mawaya anayi amitundu yosiyanasiyana ndi waya woyera pansi.
• Khazikitsani ma voltage pa multimeter kuti muyese voteji. Onetsetsani kuti yayikidwa kuti iyeze zonse za DC ndi AC zapano. Mzere wowongoka umagwiritsidwa ntchito kuimira molunjika.
• Lumikizani njira yoyeserera yakuda ku terminal yoyipa ndipo mayeso ofiira amatsogolera ku imodzi mwawaya zowunikira. Kenako yatsani kuwala.
• Samalani kuwerenga. Multimeter yanu iyenera kuwonetsa mtengo womwe umafanana ndi mphamvu ya batri yomwe mukugwiritsa ntchito. Chifukwa chake ngati batire ndi 12 volts, kuwerenga kuyenera kukhala 12 volts.

No. 5. Mayeso a Kuwala kwa Cholumikizira

Muyenera kuyeza kukana kuti muwunikire kugwirizana kwa kuyatsa. Kuti muchite izi, tsatirani njira zomwe zili pansipa:

• Onetsetsani kuti ma multimeter akhazikitsidwa kuti ayese kukana (ohms).
• Lumikizani ma multimeter otsogolera ku multimeter.
• Lumikizani kafukufuku wofiyira kumalo aliwonse okhudzana ndi kafukufuku wakuda pansi.
• Samalani kuwerenga. Ngati mtengo ndi 3 ohms, makina anu opangira ma waya akugwira ntchito bwino. (2)

Komabe, mawaya, monga kuyatsa magetsi otembenuka ndi kuyatsa, amafunikira kuwongolera kopitilira kumodzi. Komanso, kumbukirani kuti mawayawa ali ndi mndandanda wolumikizana. Multimeter yanu ikhoza kukhala ikuwonetsa kuwerengeka kocheperako.

Kuti mupewe mavuto, patulani mawayawa pochotsa mababu ndikuyang'ana iliyonse payekha. Kuti muwunike chizindikiro cholondola, masulani magetsi a brake kuti multimeter iwerenge zizindikiro zolondola zokha. Bwerezani njirayi pamagetsi ena, ndikulemba zomwe zikuwonetsedwa.

Kufotokozera mwachidule

Mukawerenga nkhaniyi, muyenera kudziwa momwe mungayesere nyali za ngolo ndi multimeter. Zotsatira zake, simuyenera kuda nkhawa chifukwa cha zomwe magetsi anu amalephereka.

Maphunziro ena a multimeter ali pansipa. Mpaka nkhani yathu yotsatira!

• Momwe mungayang'anire mitengo ya Khirisimasi ndi multimeter
• Momwe Mungagwiritsire Ntchito Cen-Tech Digital Multimeter Kuwona Voltage
• Momwe mungayesere ma amps ndi multimeter
