Ua ntej, kev sib txuas hluav taws xob ntawm lub tshuab hluav taws xob muaj plaub lub xov hlau: peb nyob ntawm cov xov hlau thiab ib qho xaim hauv av. Cov no yog siv los tswj lub tshuab hluav taws xob lub zog qhov chaw ceev 1, 2, thiab 3. Txhawm rau ntsuas qhov tsis kam, koj yuav tsum ntsuas qhov tsis kam ntawm txhua qhov ntawm peb cov xov hlau sib cais. Nov yog cov txheej txheem ntxaws:
1: Npaj ib lub multimeter. Txuas cov hlau lead dub ntawm multimeter mus rau COM chaw nres nkoj thiab cov hlau lead liab rau qhov chaw nres nkoj voltage. Tom qab ntawd, nrhiav plaub txoj hlua ntawm lub tshuab hluav taws xob lub cev muaj zog hauv qab lub thawv ntim khoom ntawm tus neeg caij tsheb.
2: Muab cov hlau lead dub ntawm lub multimeter mus rau lub tshuab hluav taws xob lub tshuab hluav taws xob, thiab cov hlau lead liab rau ntawm ib qho ntawm cov xov hlau nyob. Txheeb xyuas qhov kev nyeem ntawv ntawm multimeter's zaub kom pom tus nqi tiv thaiv, thiab yog tias xav tau, kos nws.
3: Tom qab ntawd, sim cov hlau lead liab ntawm ob lub xov hlau nyob, rov ua cov kauj ruam dhau los. Yog hais tias tus nqi kuj qhia raws li 0, nws muaj peev xwm hais tias muaj kev puas tsuaj rau lub blower lub cev muaj zog tsis kam. Nyob rau hauv cov ntaub ntawv no, lub tsheb lub tshuab blower yuav tsis tuaj yeem kho nws qhov chaw, thiab tsuas yog tuaj yeem ua haujlwm ntawm nws qhov chaw siab tshaj plaws. Hloov qhov kev tiv thaiv tej zaum yuav tsim nyog.
Tsis tas li ntawd, ua ntej ntsuas qhov kev tiv thaiv, xyuas kom tua lub tsheb thiab disconnect lub hwj chim. Txwv tsis pub, qhov ntsuas tsis kam yuav muaj qhov tsis raug tseem ceeb. Yog tias muaj tam sim no ntau dhau, lub multimeter yuav raug hlawv. Kuj tseem muaj kev pheej hmoo ntawm hluav taws xob poob siab yog tias tsis ua haujlwm ceev faj, ua rau muaj kev phom sij rau tus kheej. Yog li ntawd, yuav tsum ceev faj thaum ntsuas.
