Yuav ua li cas paub qhov tsis zoo thiab qhov zoo hlau (2 Txoj Kev Qhia)
Txheem
Hauv lub neej tiag tiag, tsis yog txhua cov xov hlau raug cim / xim liab (cov xov hlau zoo) lossis dub (tsis zoo xov hlau). Yog li ntawd, koj yuav tsum paub lwm txoj hauv kev los txiav txim qhov polarity ntawm cov xov hlau.
Kuv tuaj yeem siv ob lub xov hlau ntawm tib xim li qhov zoo thiab qhov tsis zoo? Yog nws ua tau. Qee lub tuam txhab lossis cov tib neeg tuaj yeem xaiv siv cov xov hlau ntawm tib xim rau kev sib txuas zoo thiab tsis zoo. Hauv qhov xwm txheej zoo li no, nws yuav nyuaj rau kev paub qhov txawv ntawm cov xov hlau ntawm ib leeg.
Kuv siv ntau cov xov hlau ntawm cov xim sib txawv thiab qee zaum txawm tias tib xim rau cov xov hlau zoo thiab tsis zoo. Kuv ua qhov no vim kuv tuaj yeem qhia lawv sib nrug yam tsis muaj fuss, raws li kuv lub xyoo dhau los ntawm kev siv hluav taws xob.
Hauv phau ntawv qhia no, kuv yuav qhia koj seb yuav txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm txhua hom kev sib txuas.
Feem ntau cov xov hlau zoo yog cim liab thiab cov xov hlau tsis zoo dub. Txawm li cas los xij, cov xov hlau ribbed, cov xov hlau nyiaj, lossis cov xaim liab liab kuj tuaj yeem siv rau cov xov hlau tsis zoo. Nyob rau hauv ib lub teeb pom kev zoo, cov hlau dub yog qhov zoo, thiab cov xaim dawb yog qhov tsis zoo. Copper wires yog pluses ntawm tus hais lus. Thov nco ntsoov tias cov khoom siv plugs muaj qhov kub thiab nruab nrab - cov no yog sab zoo thiab tsis zoo, tsis yog cov xov hlau tiag. Qee lub sij hawm cov xov hlau zoo thiab tsis zoo tau sau tias "+" lossis "-" thiab koj tuaj yeem txheeb xyuas lawv yooj yim.
Txoj Kev 1: Yuav ua li cas txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm cov xaim hauv cov xwm txheej
Cia peb kawm seb koj tuaj yeem txheeb xyuas cov xov hlau uas nqa qhov hluav taws xob hauv av - Kuv tab tom tham txog cov xov hlau tsis zoo hauv cov xwm txheej. Tsis txhob kov cov xov tooj liab qab nrog txhais tes liab qab. Caw koj tus kheej nrog tus neeg kuaj ua haujlwm - qee tus neeg sim yog dag, yog li xyuas kom koj sim lawv rau cov xov hlau nqa cov nqi.
Plugs rau cov khoom siv hauv tsev
Cov khoom siv hluav taws xob tsis muaj qhov zoo thiab tsis zoo ntawm cov xov hlau lossis sab. Plugs muaj qhov kub thiab nruab nrab tsis siv cov xov hlau zoo thiab tsis zoo lossis sab.
Extension cords thiab tooj liab
Saib rau ribbed xov hlau ntawm lub extension qaum - lawv feem ntau tsis zoo. Yog tias koj cov xov hlau zoo tib yam xim, feem ntau yog tooj liab, qhov tsis zoo ntawm cov hlau yog cov ribbed zoo nkauj. Taug qab qhov ntev ntawm cov xaim nrog koj txhais tes kom hnov txog qhov chaw ridged uas yuav yog cov xaim tsis zoo.
Teeb
Txhawm rau txiav txim siab qhov xwm txheej ntawm cov xov hlau hauv lub teeb pom kev zoo, nco ntsoov tias yuav muaj peb lub xov hlau - zoo, tsis zoo thiab hauv av. Cov hlau dub yog qhov zoo, cov hlau dawb yog qhov tsis zoo, thiab cov xaim ntsuab yog hauv av. Yog li thaum koj xav dai ib lub chandelier, xyuam xim rau cov kab hluav taws xob no, tab sis ceev faj. Koj tuaj yeem tua cov keyboards lossis lub ntsiab hloov. (1)
Txawm li cas los xij, tooj liab tuaj yeem siv rau hauv av.
Hais lus thiab amplifier xov hlau
Feem ntau cov xov tooj tooj liab yog qhov zoo hauv cov lus hais lossis amplifier xov hlau. Cov kab tsis zoo yog cov xov nyiaj.
Tshawb xyuas koj Tus Tswv Phau Ntawv Qhia
Koj tuaj yeem siv koj phau ntawv los txiav txim qhov xwm txheej ntawm koj cov xov hlau. Ntau hom tsheb muaj sib txawv hlau coding, yog li yuav tsum tau yuav cov phau ntawv raug.
Txoj Kev 2: Siv lub ntsuas ntsuas ntsuas ntsuas qhov zoo thiab qhov tsis zoo
Siv lub tshuab multimeter los xyuas qhov polarity ntawm cov xov hlau, analog multimeters tau yooj yim puas yog tias qhov kev sojntsuam txuas tsis raug.
Teem lub multimeter rau tam sim no-voltage - tig lub pob qhov rooj xaiv rau taw tes rau ib feem nrog "V" nyob ib sab ntawm nws. Txuas cov hlau lead dub mus rau qhov chaw nres nkoj sau npe COM, thiab tom qab ntawd txuas cov hlau lead liab mus rau qhov chaw nres nkoj cim "V". Thaum kawg, txuas cov probes ua ke los kho cov multimeter, nws yuav tsum beep (multimeter) yog tias nws ua haujlwm. Txhawm rau txheeb xyuas qhov polarity ntawm cov xov hlau, ua cov hauv qab no:
- Txuas ib qho kev sojntsuam mus rau ib lub xaim thiab tom qab ntawd lwm qhov kev sojntsuam mus rau lwm qhov kawg ntawm lwm cov hlau. Koj tuaj yeem siv cov kab nuv ntses ntawm cov xov hlau.
- Txheeb xyuas qhov kev nyeem ntawv multimeter. Yog tias tus nqi yog qhov zoo, cov xaim txuas nrog cov xaim liab ntawm lub sensor yog qhov zoo. Koj yuav tau txais kev nyeem ntawv txog 9.2V. Nyob rau hauv rooj plaub no, cov hlau txuas nrog cov hlau dub yog qhov tsis zoo.
- Yog tias qhov kev nyeem ntawv tsis zoo, koj cov xov hlau raug thim rov qab - cov xaim ntawm cov xaim liab tsis zoo thiab cov xaim ntawm cov hlau dub yog qhov zoo, sib pauv cov kev sojntsuam coj mus. (2)
- Yog hais tias tus nqi tsis zoo voltage tseem, ces koj multimeter faulty. Hloov nws.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Yuav ua li cas los txiav txim qhov nruab nrab hlau nrog ib tug multimeter
- Qhov tsis zoo voltage txhais li cas ntawm multimeter
- Yuav ua li cas txheeb xyuas lub tsheb hauv av xaim nrog lub multimeter
