Qhov sib txawv ntawm megohmmeter thiab multimeter
Lub megohmmeter yog siv los ntsuas qhov rwb thaiv tsev, xws li ntsuas lub cev muaj zog, vim tias nws tuaj yeem tso tawm qhov hluav taws xob siab tshaj 500V, thaum qhov tso zis hluav taws xob ntawm lub multimeter yog qhov tsawg heev, yog li nws tsis tuaj yeem ntsuas qhov ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob.
Megger feem ntau hu ua shaking table, feem ntau ntawm megger yog siv los ntawm tes generator, yog li nws tseem hu ua co rooj. Nws yog ntsuas hauv megaohms (MΩ). -- Lub Tsev ntawm Electrotechnical Technology
Megohmmeter yog ib qho cuab yeej ntsuas uas feem ntau siv los ntawm cov kws hluav taws xob. Lub megohmmeter feem ntau yog siv los xyuas qhov kev tiv thaiv hluav taws xob ntawm cov khoom siv hluav taws xob, cov khoom siv hauv tsev lossis cov kab hluav taws xob hauv av thiab nruab nrab ntawm theem kom ntseeg tau tias cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob thiab cov kab no ua haujlwm hauv lub xeev ib txwm muaj thiab zam kev raug mob xws li hluav taws xob poob siab thiab cov khoom siv. kev puas tsuaj.
Multimeters, tseem hu ua multiplex meters, multimeters, triple meters, multimeters, thiab lwm yam, yog indispensable ntsuas ntsuas nyob rau hauv lub hwj chim electronics thiab lwm yam departments. Feem ntau, lub hom phiaj tseem ceeb yog ntsuas qhov voltage, tam sim no thiab tsis kam.
Lub multimeter muab faib ua pointer multimeter thiab digital multimeter raws li hom zaub. Nws yog ib tug multi-function thiab ntau yam ntsuas ntsuas. Feem ntau, lub multimeter tuaj yeem ntsuas DC tam sim no, DC voltage, AC tam sim no, AC voltage, tsis kam thiab suab qib, thiab lwm yam, thiab qee qhov kuj tuaj yeem ntsuas AC tam sim no, capacitance, inductance thiab qee qhov tsis sib xws ntawm semiconductors (xws li ), thiab lwm yam.
Lub megohmmeter yog ntsuas qhov tsis kam, thiab lub multimeter kuj muaj qhov ua haujlwm ntawm kev ntsuas tsis kam. Los ntawm qhov kev pom no, zoo li nws tuaj yeem hloov tau; tab sis lub megohmmeter yog siv los ntsuas qhov ua haujlwm loj, thiab nws feem ntau yog siv los ntsuas qhov rwb thaiv tsev ntawm cov khoom siv hluav taws xob. Chav tsev yog nyob rau hauv pes tsawg megaohms los yog ntau tshaj, thiab qhov ntau ntawm cov multimeter feem ntau yog nyob rau hauv lub ohm theem, yog li thaum lub kuj loj, nws yuav tso saib infinity, thiab cov ntaub ntawv yuav tsis nyeem tau.
Yog li ntawd, ib tug multimeter tsis tuaj yeem hloov lub megohmmeter.
Lub megohmmeter yog lub ntsuas ntsuas siab, thiab qhov dav dav multimeter yog qhov ntsuas nruab nrab tsis kam. Lub rwb thaiv tsev tsis kam ntawm cov av thiab hauv av yog lub hauv paus rau kev txiav txim ua ntej seb cov khoom puas tuaj yeem muab tso rau hauv kev ua haujlwm.
Lub ohm iav ntawm lub multimeter feem ntau yog siv los ntsuas qhov ntsuas tus nqi ntawm cov khoom siv, thiab nws tseem tuaj yeem siv los ntsuas qhov txuas ntxiv ntawm cov xov hlau. Thaum tsis muaj megohmmeter hauv kev saib xyuas, nws tseem tuaj yeem ntsuas qhov ntsuas hauv av rwb thaiv tsev ntawm cov khoom siv (lossis cov khoom siv hluav taws xob).
Txuas 2, lub megohmmeter yog siv rau kev ntsuas rwb thaiv tsev, xws li ntsuas lub cev muaj zog, vim tias nws tuaj yeem tso tawm qhov hluav taws xob siab tshaj 500V, thiab qhov tso zis hluav taws xob ntawm multimeter yog qhov tsawg heev, yog li nws tsis tuaj yeem ntsuas qhov ntsuas hluav taws xob ntawm hluav taws xob. khoom siv.
Lub megohmmeter yog siv los ntsuas kev tiv thaiv rwb thaiv tsev, feem ntau hu ua shaker. Muaj cov tshuab hluav taws xob sab hauv, feem ntau siv yog 250V, 500V, 1000V, 2500V. -- Lub Tsev ntawm Electrotechnical Technology
Multimeter yog siv los ntsuas AC thiab DC voltage, DC tam sim no, tsis kam, thiab tuaj yeem ntsuas qhov loj ntawm triodes, nrog rau diodes, capacitors, inductances, thiab lwm yam.

Lub megohmmeter yuav tawm 500V, tab sis tam sim no tsawg heev. Lub multimeter yuav tawm hluav taws xob thaum ntsuas qhov tsis kam, thiab qhov hluav taws xob tsawg heev; Thaum ntsuas qhov voltage thiab tam sim no, nws yuav tsis tawm qhov hluav taws xob.
