Qhov tseem ceeb ntawm Clamp Meters
Lub clamp ammeter yog kev sib xyaw ua ke ntawm tam sim no transformer thiab ammeter. Cov tub ntxhais hlau ntawm qhov tam sim no transformer tuaj yeem qhib thaum lub qhov ciaj ntswj yog nyem; cov hlau los ntawm kev ntsuas tam sim no tuaj yeem dhau los ntawm cov tub ntxhais hlau. Lub ntsuas hluav taws xob ntsuas hluav taws xob dhau los ua lub hauv paus kauj ntawm tam sim no transformer, thiab tam sim no yog induced nyob rau hauv lub thib ob kauj tam sim no.
Feem ntau, thaum ntsuas qhov tam sim no nrog lub ammeter zoo tib yam, nws yog ib qho tsim nyog yuav tsum tau txiav tawm Circuit Court thiab kaw lub voj voog ua ntej txuas lub ammeter rau kev ntsuas. Qhov no yog teeb meem heev, thiab qee zaum lub cev muaj zog hauv kev ua haujlwm ib txwm tsis tso cai rau qhov no. Lub sijhawm no, nws yooj yim dua los siv lub clamp ammeter, uas tuaj yeem ntsuas qhov tam sim no yam tsis muaj kev txiav tawm Circuit Court.
Lub clamp meter tuaj yeem hloov mus rau ntau qhov sib txawv los ntawm kev hloov lub iav ntawm qhov hloov. Tab sis nws tsis raug tso cai ua haujlwm nrog hluav taws xob thaum hloov cov iav. Lub clamp meter feem ntau tsis siab qhov tseeb, feem ntau yog 2.5 txog 5 qib. Rau qhov yooj yim ntawm kev siv, muaj cov keyboards ntawm ntau yam hauv lub 'meter' rau kev ua haujlwm ntawm kev ntsuas qhov sib txawv ntawm qhov tam sim no thiab ntsuas voltage.
Clamp meters yog thawj zaug siv los ntsuas alternating tam sim no. , tab sis tam sim no lub multimeter kuj muaj qee qhov haujlwm, uas tuaj yeem ntsuas AC thiab DC voltage, tam sim no, capacitance, diode, triode, tsis kam, kub, zaus thiab lwm yam.
Lub clamp ammeter tuaj yeem ntsuas lub photovoltaic DC tam sim no thiab cov zis AC tam sim no ntawm inverter. Kev saib xyuas tshwj xeeb yuav tsum tau them rau: qee qhov clamp ammeters tsis muaj DC muaj nuj nqi, thiab lub puab tsaig yuav tsum raug kaw kom nruj, thiab qhov ntau yam tsis tuaj yeem hloov nrog lub hwj chim.
