Digital multimeter PK pointer multimeter, leej twg zoo dua!
Multimeter, mloog lub npe, peb paub tias nws muaj ntau lub luag haujlwm, yog tus kws tshaj lij hluav taws xob * kev hlub. General multimeter tuaj yeem ntsuas DC tam sim no, AC thiab DC voltage, tsis kam, thiab lwm yam, muaj qee qhov tuaj yeem ntsuas lwm qhov ntsuas, xws li AC tam sim no, capacitance, inductance, thiab lwm yam, tshwj xeeb tshaj yog ntsuas kub.
Raws li kev sib txawv ntawm nws cov zaub, multimeter tuaj yeem muab faib ua digital multimeter thiab pointer multimeter.
Niaj hnub no, qhov nrov ntawm kev ua lag luam feem ntau yog digital multimeter, pointer multimeter maj mam hloov.
Yog li yog vim li cas cov digital multimeter ntau thiab nrov dua, thaum lub pointer multimeter yog ntau thiab ntau tshem tawm?
Pointer multimeter sab hauv cov qauv yog qhov yooj yim, yog li txheeb ze rau digital multimeter, tus nqi tsim khoom qis dua, kev ua haujlwm kuj tseem me me, thiab digital multimeter sab hauv yog ntau lub hom phiaj kev sib txuas, txawm hais tias tus nqi siab dua li tus pointer hom. , tab sis nws txoj haujlwm ntau dua, xws li capacitance, inductance, zaus, kub thiab lwm yam tuaj yeem ntsuas.
Niaj hnub nimno kev lag luam tshuab yog ntau thiab ntau dua, lub sij hawm xav tau ib tug multi-functional hwj chim detector meter yug, thiab yuav dhau los ua mainstream, pointer hom multimeter yuav ib txwm raug tshem tawm, tab sis txheeb ze rau cov multimeter, nws kuj muaj nws tus kheej zoo!
Ua ntej ntawm tag nrho cov, lub internal pointer multimeter yog feem ntau tsis muaj amplifier, yog li ntawd lub internal kuj yog me me, uas ua rau nws siab rhiab heev.
Qhov thib ob, raws li tau hais los saum toj no, cov qauv sab hauv ntawm lub pointer multimeter yog qhov yooj yim, yog li tus nqi qis dua.
Thaum kawg, qhov tso zis hluav taws xob ntawm tus pointer multimeter yog siab dua, thiab tam sim no kuj loj dua, yog li nws tuaj yeem yooj yim heev los ntsuas lub teeb-emitting diode.
Hauv kev xaus, txhua yam muaj nws tus kheej zoo, tsuas yog digital multimeter thiab pointer multimeter ib qho kev sib piv, qhov zoo yog muaj zog, yog li nws yuav dhau los ua cov khoom lag luam tseem ceeb!
