Dab tsi yog cov khoom siv multimeter
1. Tso cov lej thiab qhov tseeb ntawm multimeter
Cov lej tso saib thiab qhov tseeb yog qhov yooj yim tshaj plaws thiab tseem ceeb ntsuas ntsuas ntawm multimeter. Feem ntau hais lus, ntau dua tus lej tso tawm los ntawm multimeter, qhov tseeb dua, thiab rov ua dua.
2. Txoj kev ntsuas thiab AC zaus teb ntawm multimeter
Txoj kev ntsuas ntawm multimeter feem ntau yog rau kev ntsuas ntawm AC cov cim. Nrog rau kev hloov pauv ntawm qhov zaus ntawm AC teeb liab, ntau cov lus teb zaus tshwm sim, uas cuam tshuam rau kev ntsuas ntawm multimeter. Feem ntau muaj ob txoj hauv kev rau multimeters los ntsuas AC signals: tus nqi nruab nrab thiab qhov tseeb RMS ntsuas.
3. Muaj nuj nqi thiab ntsuas ntau yam
Multimeters sib txawv, lawv cov tuam txhab yuav tsim cov kev ntsuas kev ua haujlwm sib txawv. Ordinary multimeters tuaj yeem kuaj AC thiab DC voltage, tam sim no, tsis kam, on-off, thiab lwm yam, tab sis qee qhov multimeters tsis muaj qhov ua haujlwm tam sim no txhawm rau txo cov nqi.
4. Ntsuas kev ruaj ntseg thiab kev tiv thaiv
Multimeter zoo muaj kev tiv thaiv tus kheej zoo. Piv txwv li, thaum ib co multimeters tau muab tso rau hauv qhov tsis ncaj ncees lawm xeem kab, nws yuav cia li tsim ib tug buzzer tswb... Thaum muas ib tug multimeter, tsis txhob blindly ntshaw pheej yig, tab sis yuav siv tau thiab yooj yim rau siv.
