momwe mungayesere mawaya abwino ndi oyipa ndi ma multimeter

Ubwino wa mawu omvera a sipikala wanu chinthu chimodzi chomwe simuchiwona mopepuka, makamaka kwa okonda nyimbo. 

Nthawi zina mungafunike kukweza mawu anu onse, m'malo mwa oyankhula, kapena kusintha zomwe mumamvetsera kuti zikhale zopindulitsa. Chilichonse chomwe chili, mtundu wa mawu omaliza amatengera momwe zida zoyankhulira zimayikidwira. wawaya.

Nkhaniyi ikutsogolerani zonse zomwe muyenera kudziwa za speaker polarity, kuphatikizapo momwe mungayang'anire ngati mawaya alumikizidwa bwino komanso zotsatira za mawaya osauka. Tiyeni tiyambe.

Kodi polarity ndi chiyani ndipo chifukwa chake ndikofunikira

Polarity ya okamba anu imagwirizana ndi mawaya oyipa ndi abwino a okamba anu ndipo ndikofunikira pamawu agalimoto yanu. 

Chigawo chilichonse cha makina omvera chimadutsa mu amplifier. Izi zikuphatikizapo RCA / telefoni zingwe zopita ku mutu wa wailesi komanso zingwe zamagetsi zomwe zikubwera, zingwe zapansi ndipo ndithudi mawaya amachokera ku okamba anu. 

Makina ena omvera agalimoto ndi ovuta kwambiri chifukwa amaphatikiza zigawo zambiri ndipo amakhala ndi zingwe zovuta komanso mawaya. Komabe, kukhazikitsidwa kofunikiraku kumakhalabe maziko a ntchito zofunika kwambiri zamawu anu.

Mawaya awiri amabwera molunjika kuchokera kwa okamba anu ndipo mwina ndi abwino kapena oyipa. Kawirikawiri, okamba akagwiritsidwa ntchito payekha, palibe chodetsa nkhawa, chifukwa amagwira ntchito mopanda waya.

Komabe, pogwiritsira ntchito okamba mawu aŵiri m’mawu ofanana (omwe ndi makonzedwe achibadwa), kupotoza kapena kusalankhula kungachitike. Komanso, popeza mufunika kulumikiza okamba anu ku chokulitsa kuti mumveke bwino, mutha kukumananso ndi kusokoneza kapena kusokoneza phokoso. Izi ndichifukwa choti amplifier yapereka ma terminals abwino komanso oyipa.

Ndiye mungadziwe bwanji waya womwe uli wabwino komanso woyipa? Pali njira zingapo zochitira izi, koma zabwino kwambiri komanso zopanda cholakwika ndikugwiritsa ntchito multimeter.

Momwe mungayesere mawaya abwino ndi oyipa ndi ma multimeter

Kuti muwone polarity ya mawaya a speaker, mumalumikiza mawaya olakwika (wakuda) ndi abwino (ofiira) pawaya iliyonse. Ngati multimeter ikuwonetsa zotsatira zabwino, ndiye kuti mawaya anu amalumikizidwa ndi mawaya a polarity omwewo, ndiye kuti, kafukufuku wofiyira wofiyira amalumikizidwa ndi waya wabwino, komanso mosemphanitsa.. 

Mafotokozedwe owonjezera pankhaniyi adzaperekedwa pansipa.

Multimeter ya digito ndi chida chomwe chimagwiritsidwa ntchito kuyesa zida zingapo zamagetsi ndi mayunitsi angapo amiyezo. Mukayang'ana mawaya oyankhula kapena china chilichonse mgalimoto, muyenera kuyika ma multimeter anu ku DC voltage.

Lumikizani zoyeserera zabwino (zofiira) ndi zoyipa (zakuda) ndikupitilira motere.

1. Letsani zigawo zonse

Musanayese chilichonse, onetsetsani kuti zida zonse zoyankhulirana zachotsedwa pamawu anu. Izi ndizofunikira kuti mutetezeke ku kugwedezeka kwamagetsi.

Chimodzi mwazochita zabwino ndikujambula chithunzi cha makina omvera musanadutse chilichonse mwa zigawozo. Chithunzichi chimagwiritsidwa ntchito ngati chiwongolero polumikizanso zigawo kuti musalakwitse.

2. Ikani mawaya pa mawaya oyankhula

Pali mawaya awiri akubwera kuchokera ku ma sipika. Nthawi zambiri mawayawa sadziwika kotero simudziwa kuti ndi yabwino kapena yoyipa.

Tsopano muyenera kulumikiza njira zolakwika ndi zabwino za multimeter ku waya uliwonse. Mumalumikiza waya wofiyira wabwino ku waya wina, kulumikiza waya wakuda woyipa ku winayo, ndikuwona kuwerenga kwa ma multimeter. Apa ndipamene mumapanga chisankho.

3. Yang'anani kuwerenga kolimbikitsa kapena kolakwika

Ngati chiwongolero chabwino chilumikizidwa ndi waya wabwino ndipo chowongolera choyipa chikulumikizidwa chimodzimodzi ndi waya woyipa, DMM imawerenga zabwino.

Kumbali ina, ngati chiwongolero chabwino chikugwirizana ndi waya wolakwika ndipo chowongolera choyipa chikugwirizana ndi waya wabwino, multimeter idzawonetsa kuwerenga kolakwika.

wosewera mpira

Mulimonsemo, mukudziwa waya womwe uli wabwino komanso womwe uli woyipa. Kenako mumawalemba moyenera kuti mudzafune kulumikizana nawo nthawi ina.

Mukayika mawaya pamawaya, kugwiritsa ntchito tatifupi za ng'ona kumathandizira kuti ntchitoyi ikhale yosavuta. Tepi imathandizanso polemba mawaya.

4. Lumikizaninso zigawozo ku makina omvera

Pambuyo polemba mawaya moyenera kuti ndi abwino komanso oyipa, mumalumikizanso zida zonse zoyankhulira ku makina omvera. Chithunzi chomwe mudajambula kale chingakhale chothandiza apa.

Monga tafotokozera kale, pali njira zina zoyesera mawaya abwino ndi oipa a okamba anu.

Kuwunika kwa batri polarity

Mawaya olankhula amatha kuyang'aniridwa pongogwiritsa ntchito batire yotsika. Apa ndipamene mumayikapo mfundo zabwino ndi zoipa pa batri yomwe mukufuna kugwiritsa ntchito ndikugwirizanitsa mawaya kuchokera kwa okamba nkhani kupita kwa aliyense.

Ngati cholankhulira chikatuluka, mawaya abwino ndi oyipa amalumikizidwa bwino. Ngati cone ikanikizidwa mkati, ndiye kuti mawaya amasakanikirana. 

Mulimonse momwe zingakhalire, mumadziwanso waya kapena terminal yomwe ili yabwino kapena yoyipa. Ngati simukumvetsetsa, vidiyoyi ikuthandizani kuwunikira. 

Kuyang'ana ndi ma code amitundu

Njira ina yodziwira polarity ya speaker ndiyo kugwiritsa ntchito ma coding amtundu woyenera. 

Waya wabwino nthawi zambiri amakhala wofiyira ndipo waya wopanda pake amakhala wakuda. Komabe, izi sizili choncho nthawi zonse chifukwa zimatha kusakanikirana kapena kungophimbidwa ndi mtundu womwewo. Yang'anani bukhu la ogwiritsa ntchito ngati iyi ndi wokamba watsopano.

Njira imeneyi si yothandiza nthawi zonse.

Pomaliza

Kuzindikira polarity ya mawaya a sipikala sikovuta kusweka. Mukungoyang'ana zizindikiro zamtundu ndipo ngati palibe, mumayang'ana kayendedwe ka ma cones oyankhula ndi batri kapena zowerengera ndi multimeter.

Njira iliyonse yomwe mumagwiritsa ntchito, kulumikizana koyenera kumatsimikizira kumveka bwino komwe mungapeze pamawu anu.

Mafunso ofunsidwa kawirikawiri

Mumadziwa bwanji kuti waya woyankhulirana ndi wabwino ndi iti?

Kuti mudziwe kuti ndi waya iti yolankhulira yomwe ili yabwino komanso yolakwika, mutha kugwiritsa ntchito ma code amtundu kapena gwiritsani ntchito multimeter kuti muwone polarity. Kuwerenga kwabwino kwa ma multimeter kumatanthauza kuti zotsogola zimalumikizidwa ndi mawaya oyenera. Ndiko kuti, kafukufuku wakuda wakuda amalumikizidwa ndi waya wa wokamba nkhani komanso mosinthanitsa.

Kodi mungadziwe bwanji ngati speaker polarity ndi yolondola?

Kuti mudziwe ngati polarity ya wokamba nkhani ndi yolondola, mumagwirizanitsa mawaya a multimeter ku ma terminals awiri a wokamba nkhani ndikudikirira kuwerenga. Mtengo wabwino umatanthawuza kuti polarity ya okamba ndiyolondola.

Kodi ndingadziwe bwanji ngati oyankhula anga alumikizidwa kumbuyo?

Kuti mudziwe ngati choyankhulira chanu chalumikizidwa chakumbuyo, mumalumikiza ma multimeter ku waya uliwonse kuchokera ku ma terminals a speaker. Kuwerenga koyipa pa multimeter kumatanthauza kuti olankhula amalumikizidwa mobwerera.

Kodi A ndi B pa okamba amatanthauza chiyani?

Mukamagwiritsa ntchito zolandilira za A/V, Olankhula A ndi B amakhala ngati masitayilo osiyanasiyana otulutsa ma audio okhala ndi olankhula osiyanasiyana olumikizidwa kwa iwo. Mwina mukusewera kudzera pa oyankhula pa tchanelo A, kapena mukusewerera okamba pa tchanelo B, kapena mukusewera matchanelo onse awiri.

Kodi mumadziwa bwanji kuti wolankhula kumanzere ndi yemwe ali wolondola?

Kuti mudziwe amene ali kumanzere kapena kumanja, ndi bwino kuyesa mawu. Mumayimba mawu oyeserera kudzera mwa okamba ndikumvetsera komwe zotulutsa zomvera zoyenera zimachokera.
