Lub cav tsuj hluav taws xob yog cov kauj ruam hloov hluav taws xob. Nws hloov qis qhov tsawg kawg ntawm lub tsheb hluav taws xob sib txuas rau qhov hluav taws xob siab. Cov phiajcim ntawm lub laj kab hluav taws xob tsis zoo nkauj feem ntau tsis yog txhua lub txim nyob rau kev ua haujlwm. Ringing lub kauj tiv thaiv roj yog yooj yim heev. Koj tsuas yog xav tau ohmmeter lossis multimeter.

Chev tshem tawm cov ciaj ntswj, ohmmeter lossis multimeter
Cov Lus Qhia
Kauj ruam 1
Qhib cov hood thiab nrhiav qhov chaw nyob ntawm lub tshuab pa taws. Sib txuas ntawm cov xov hluav taws xob high-voltage los ntawm nws. Nws feem ntau yog mus rau qhov chaw sib cuag. Txheeb txuas rau cov txuas ntxiv (+) thiab rho tawm (-) cov xaim los ntawm lub kauj. Tshem cov kauj los ntawm lub cev tsheb.
Kauj ruam 2
Tom ntej no, xyuas cov tsis kam ntawm kev sib hloov ntawm lub caij ob. Txhawm rau ua qhov no, txuas ib qho ohmmeter rau qhov tsis zoo (-) thiab siab siv hluav taws xob. Qhov tsis kam ntawm lawv yuav tsum tsis pub dhau 4.5 kOhm - 6.5 kOhm.
Kauj ruam 3
Cov kauj ruam tom ntej yog xyuas lub kauj rau rwb thaiv tsev lossis hauv av. Txuas ib qho kev sib cuag ntawm ohmmeter rau lub cev ntawm lub log tiv thaiv, thiab tus thib ob hauv nyeg mus rau txhua qhov tiv tauj: ntxiv rau, rho tawm thiab qhov ntsuas hluav taws xob siab. Cov tawm tsam ntawm txhua tus tiv tauj thiab lub cev coil yuav tsum muaj tsawg kawg yog 50 mΩ.
