Teem lub multimeter los ntsuas hluav taws xob . Ntxig aprobe rau hauv txhua qhov los ntsuas kab hluav taws xob . Lub qhov hluav taws xob ua haujlwm zoo muab kev nyeem ntawv ntawm 110 txog 120 volts. Yog tias tsis muaj kev nyeem ntawv, kuaj cov kab hluav taws xob thiab qhov hluav taws xob.

Nyob rau hauv tas li ntawd, yuav ua li cas los xyuas qhov voltage nrog ib tug multimeter?

Txuas cov tshuaj ntsuam dub rau hauv COM thiab cov tshuaj ntsuam liab liab rau hauv lub qhov (socket) cim VΩ. Teem lub sijhawm rau DC lossis AC hluav taws xob thiab kov cov lus qhia sojntsuam mus rau ob lub ntsiab lus ntawm qhov twg hluav taws xob yuav tsum ntsuas.

Tsis tas li ntawd, koj yuav ua li cas paub yog tias qhov voltage yog ib theem? Ntsuas Ib Theem Voltage (115 Volt Systems)

  1. Siv cov txheej txheem ntawm kev xeem, Ntxig cov kev sojntsuam dub ntawm lub testlead rau hauv lub 'meter''s Common (COM) chaw nres nkoj thiab cov liab sojntsuam ntawm cov hlau lead rau hauv qhov chaw nres nkoj cim rau voltage thiab ohms.
  2. Teem koj qhov tseeb RMS hluav taws xob ntau lub ntsuas kom nyeem "Ohms" lossis "Continuity."

Kuj nug, ua li cas koj sim 240 volts?

Tig lub dial ntawm koj lub multimeter thiab teem rau 120 hluav taws xob . Ntxig lub hau hlau ntawm qhov kev sojntsuam liab rau hauv ib qho ntawm 120- hluav taws xob slots, thiab plam lub hau hlau ntawm blackprobe rau hauv nruab nrab (hauv av) qhov. Koj lub multimeter yuav tsum nyeem kwv yees li 120 hluav taws xob AC. Yog tias nws tsis yog, ces qhov circuit no puas lawm.

Dab tsi yog cov cim qhia ntawm tus rhuav tshem tsis zoo?

Circuit Breaker Warning Signs

  • Hluav taws kub tsw nyob rau hauv hluav taws xob vaj huam sib luag. Ib txoj hauv kev los qhia yog tias koj xav tau qhov hloov hluav taws xob hloov hluav taws xob yog hnia ib puag ncig thiab pom tias koj hnov tsw tsw ntxhiab los ntawm lub vaj huam sib luag.
  • Breaker yuav tsis rov pib dua.
  • Lub cev puas tsuaj.
  • Breakers Tripping nquag.
  • Hnub nyoog laus.
