Yuav ua li cas ntsuas tam sim no thiab hloov pauv ntawm digital clamp meter
Clamp meters tuaj yeem hloov mus rau ntau qhov sib txawv los ntawm kev hloov lub zog ntawm qhov hloov pauv hloov. Txawm li cas los xij, nws tsis raug tso cai ua haujlwm nrog hluav taws xob thaum hloov cov iav. Clamp meter dav dav tsis siab, feem ntau 2.5 ~ 5 qib. Txhawm rau kom yooj yim rau kev siv lub rooj, muaj ntau qhov sib txawv ntawm kev hloov pauv rau kev ntsuas qhov sib txawv ntawm qhov ntsuas tam sim no thiab qhov ntsuas hluav taws xob muaj nuj nqi.
Clamp meter tau pib siv los ntsuas AC tam sim no, tab sis tam sim no lub multimeter muaj cov haujlwm nws kuj muaj, tuaj yeem ntsuas AC thiab DC voltage, tam sim no, capacitance, diode, transistor, tsis kam, kub, zaus thiab lwm yam.
Lub tshuab hluav taws xob digital yog cov cuab yeej siv hluav taws xob ntau lub hom phiaj, qee zaum hu ua multimeter, multi-meter, multi-meter, lossis tri-meter, uas feem ntau muaj cov haujlwm ntawm ammeter, voltmeter, ohmmeter, thiab lwm yam. Lub luag haujlwm tseem ceeb yog ntsuas qhov voltage, tsis kam thiab tam sim no. Digital multimeter, raws li niaj hnub siv ntau lub hom phiaj ntsuas hluav taws xob, feem ntau yog siv hauv kev ntsuas lub cev, hluav taws xob thiab hluav taws xob.
Clamp Meter Measure Wire Resistance Yuav Ntsuas Li Cas
Ib feem ntawm lub clamp-on ammeter yog nrog kev ntsuas kev ua haujlwm, yog tias koj muaj lub clamp-on ammeter ntawm tes nrog txoj haujlwm no, koj tuaj yeem ua raws li cov kauj ruam hauv qab no los ntsuas.
Kev ntsuas hluav taws xob:
① Tig qhov hloov mus rau qhov tsim nyog ntawm kev tiv thaiv thaiv.
② Khaws qhov hloov pauv hauv lub xeev tso tawm.
③ Txuas tus cwj mem liab mus rau Ω davhlau ya nyob twg thiab tus cwj mem dub rau COM davhlau ya nyob twg.
④ cov cwj mem liab thiab dub txuas nrog ob kawg ntawm cov xaim nyob rau hauv kev sim, ntsuas qhov tsis kam ntawm cov xaim siv, cov kab yuav tsum raug txiav tawm ntawm lub hwj chim, thiab lub capacitor txuas nrog cov xaim yuav tsum tau tso tawm tag nrho ua ntej ntsuas. .
Hlau on-off test
① Tig qhov hloov mus rau 200Ω (los yog buzzer) thaiv.
② Cov cwj mem liab thiab dub txuas nrog Ω kawg COM kawg.
③ Yog tias qhov kev tawm tsam ntawm cov cwj mem liab thiab xim dub tsawg dua (50s25) Ω, lub suab nrov nrov nrov.
