Yuav ua li cas txheeb xyuas ib qho -theem lub qhov (socket) uas tsis yog- tiv tauj voltage tester cwj mem tshuaj xyuas teeb
Ib zaug -theem ob puas thiab ob lub qhov (socket) feem ntau muab faib ua ob lub qhov thiab peb qhov. Sab laug, nruab nrab thiab sab xis ntawm ob lub qhov yog theem, thiab sab laug, nruab nrab thiab sab xis yog hauv av.
Ib qho -theem 220 qhov (sockets), hla- txuas cov teeb tshuaj ntsuam xyuas kom paub tseeb. Sab laug, nruab nrab thiab sab xis yog txuas nrog lub teeb tshuaj ntsuam xyuas, yog tias lub teeb zoo li qub, nws yog qhov tseeb. Lub teeb hluav taws xob qhib hluav taws xob raug kaw, thiab lub teeb pom kev tsis zoo flashes.
Peb qhov - qhov (socket) tau sim, thiab lub teeb hauv av sab saud ntawm txoj cai theem kuj tseem nyob, thiab lub teeb nruab nrab sab laug thiab sab saud tsis nyob, txwv tsis pub cov xaim tsis raug.
