Qhov txawv ntawm ib tug multimeter thiab ib tug megohmmeter
Lub megohmmeter yog siv los ntsuas qhov rwb thaiv tsev, xws li kev ntsuas ntawm 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 cov khoom siv hluav taws xob tsawg heev, yog li nws tsis tuaj yeem ntsuas qhov ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob.
Megger (Megger) feem ntau hu ua shaker, thiab feem ntau ntawm megger yog siv los ntawm lub tshuab hluav taws xob tes, yog li nws tseem hu ua shaker. Nws qhov ntsuas yog nyob rau hauv megohms (MΩ). -- Lub Tsev ntawm Hluav Taws Xob Technology
Megohmmeter yog ib hom kev 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 rau hauv av thiab nruab nrab ntawm theem, txhawm rau xyuas kom meej tias 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. shock casualties thiab khoom puas.
Multimeters, tseem hu ua multimeters, multimeters, peb-meters, multimeters, thiab lwm yam, yog qhov tseem ceeb ntsuas ntsuas hauv hluav taws xob hluav taws xob thiab lwm lub tuam tsev. 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 qho kev ntsuas ntau yam thiab ntau yam 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 ).
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 pes tsawg megohms lossis ntau dua, thiab qhov ntau ntawm multimeter feem ntau yog nyob rau theem ohm, yog li thaum qhov kev tawm tsam loj, nws yuav tso saib infinity, thiab cov ntaub ntawv tsis tuaj yeem nyeem tau.
Yog li ntawd, lub multimeter tsis tuaj yeem hloov lub megohmmeter.
Lub megohmmeter yog lub ntsuas ntsuas siab. General multimeter yog lub ntsuas ntsuas nruab nrab. Lub megohmmeter tsuas tuaj yeem ntsuas qhov tsis kam. Ntxiv nrog rau kev ntsuas kev tiv thaiv, multimeter kuj tuaj yeem ntsuas qhov voltage, tam sim no, transistors, thiab lwm yam. Megger feem ntau yog siv los ntsuas ob qho khoom siv hluav taws xob Lub rwb thaiv tsev ntawm cov av thiab hauv av yog lub hauv paus rau kev txiav txim siab ua ntej seb cov khoom puas tuaj yeem muab tso rau hauv kev ua haujlwm. .
Lub ohm ntau yam ntawm lub multimeter yog tsuas yog siv los ntsuas qhov ntsuas tus nqi ntawm cov khoom siv, thiab nws kuj tuaj yeem siv los ntsuas qhov on-off ntawm cov hlau. Thaum tsis muaj megger thaum lub sijhawm tu, nws kuj tuaj yeem ntsuas qhov ntsuas hluav taws xob ntawm cov khoom siv (lossis cov khoom siv hluav taws xob) rau hauv av.
Txuas 2, lub megohmmeter yog siv los ntsuas qhov rwb thaiv tsev, xws li rau lub cev muaj zog, vim tias nws tuaj yeem tso tawm qhov hluav taws xob siab tshaj 500V, thiab cov zis hluav taws xob ntawm multimeter yog qhov tsawg heev, yog li nws tsis tuaj yeem ntsuas qhov ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob.
Lub megohmmeter yog siv los ntsuas cov rwb thaiv tsev tiv thaiv, feem ntau hu ua lub ntsuas ntsuas. Muaj lub tshuab hluav taws xob sab hauv, thiab cov khoom siv feem ntau yog 250V, 500V, 1000V, thiab 2500V. -- Lub Tsev ntawm Hluav Taws Xob Technology
Multimeter yog siv los ntsuas AC thiab DC voltage, DC tam sim no, tsis kam, thiab tuaj yeem ntsuas qhov loj ntawm triode, nrog rau diodes, capacitors, inductance, thiab lwm yam.
Lub megohmmeter yog siv los ntsuas cov rwb thaiv tsev tiv thaiv, feem ntau hu ua lub ntsuas ntsuas. Muaj lub tshuab hluav taws xob sab hauv, thiab cov khoom siv feem ntau yog 250V, 500V, 1000V, thiab 2500V. Multimeter yog siv los ntsuas AC thiab DC voltage, DC tam sim no, tsis kam, thiab tuaj yeem ntsuas qhov loj ntawm triode, nrog rau diodes, capacitors, inductance, thiab lwm yam.
Thaum siv megohmmeter, qhov hluav taws xob ntawm 500V tau tawm, tab sis tam sim no me me heev. Lub multimeter yuav tawm hluav taws xob thaum ntsuas qhov tsis kam, thiab qhov hluav taws xob tsawg heev; Nws yuav tsis tawm qhov hluav taws xob thaum ntsuas qhov hluav taws xob thiab tam sim no.
European meter yog siv los ntsuas cov rwb thaiv tsev tiv thaiv, feem ntau hu ua shaker meter. Muaj lub tshuab hluav taws xob sab hauv, thiab cov khoom siv feem ntau yog 250V, 500V, 1000V, thiab 2500V.
Multimeter yog siv los ntsuas AC thiab DC voltage, DC tam sim no, tsis kam, thiab tuaj yeem ntsuas qhov loj ntawm triode, nrog rau diodes, capacitors, inductance, thiab lwm yam.
