Tsis tiv tauj voltage nrhiav tau nrog ib tug multimeter
Tsis tiv tauj voltage nrhiav kom tau
Lub Fluke 117DMM kuj suav nrog cov khoom siv hluav taws xob uas tsis sib cuag hluav taws xob tswj hluav taws xob engineering network, txhua txoj cai tshwj tseg, VoltAlert. Nws nyob saum lub LCD zaub screen ntawm lub ntsuas vaj huam sib luag, thiab lub induction Circuit Court tuaj yeem kuaj pom muaj AC voltage, emit ib lub suab, thiab ua rau lub teeb qhia LED nyob rau hauv nruab nrab ntawm lub LCD zaub screen kom emit liab teeb. Rau AC voltage nrhiav pom, qhov ntsuas no tuaj yeem muab ob qho kev teeb tsa rhiab heev. Ntawm lawv, qhov "Lo" (qis) qhov teeb tsa yog siv los ntsuas cov embedded phab ntsa sockets, wiring boards, embedded industrial sockets, thiab ntau yam xov hlau. Nyob zoo rhiab qhov chaw tso cai rau
Tshawb xyuas qhov hluav taws xob ntawm lwm cov khoom siv hluav taws xob zais lossis cov qhov (sockets), uas nws qhov hluav taws xob AC feem ntau muab zais hauv qhov txuas nws tus kheej. Nyob rau hauv qhov "Nyob zoo", VoltAlert? Nws tuaj yeem txheeb xyuas seb cov xov hlau tsis muaj hluav taws xob tsawg li 4V nyob. Qhov tshwj xeeb no tso cai rau cov kws tshaj lij los txiav txim siab sai sai seb lub vaj huam sib luag, tswj txee, lossis cov khoom siv tau muaj kev ntseeg siab. Yog tias AC voltage raug kuaj pom, cov neeg ua haujlwm daws teeb meem tuaj yeem siv Auto-V / LoZ los txiav txim seb qhov ntsuas hluav taws xob puas yog qhov tsis muaj hluav taws xob lossis qhov hluav taws xob nyuaj.
Ua ntej ntsuas kev sib cuag, ua ntej siv lub ntsuas hluav taws xob tsis sib cuag los xyuas seb qhov muaj qhov hluav taws xob. Txhua txoj cai tshwj tseg los ntawm Control Engineering Network tuaj yeem muab kev tiv thaiv ntxiv rau kev ntsuas.
