Dab tsi yog qhov sib txawv ntawm digital multimeter thiab oscilloscope?
Multimeters thiab oscilloscopes feem ntau siv cov cuab yeej. Multimeters thiab oscilloscopes paub txog cov tshuab hluav taws xob. Nws tuaj yeem hais tias yog ib qho cuab yeej tseem ceeb rau kev tshawb fawb thiab kev tsim kho, kev debugging, thiab kev saib xyuas. Tau kawg, kev ua haujlwm ntawm multimeter thiab oscilloscope yog txawv kiag li.
multimeter
Muaj ob hom multimeters: hom pointer thiab hom digital; Cov pointer hom tau pib raug tshem tawm, thiab tam sim no digital multimeters feem ntau yog siv.
Multimeter tuaj yeem siv los ntsuas qhov tsis kam, AC / DC voltage, AC / DC tam sim no, diodes, capacitors, zaus, thiab lwm yam. Lub multimeter yog qhov yooj yim thiab siv tau yooj yim. Ntev npaum li lub iav tau teeb tsa rau qhov xav tau kev ntsuas kev ua haujlwm iav, qhov ntsuas tuaj yeem ua tiav.
Thaum siv multimeter los ntsuas tam sim no, yuav tsum tau them nyiaj tshwj xeeb. Txhawm rau ntsuas qhov tam sim no, lub tshuab hluav taws xob yuav tsum tau txuas nrog hauv series rau hauv Circuit Court, thiab cov kev sojntsuam liab yuav tsum tau muab tso rau hauv qhov chaw tsim nyog. Yog tias qhov tam sim no tshaj qhov ntau, lub fuse ntawm multimeter yuav raug hlawv.
oscilloscope
Oscilloscope thiab multimeter sib txawv, multimeter tsuas tuaj yeem tso saib cov ntsuas ntsuas. Oscilloscope tuaj yeem ntsuas cov teeb liab sai thiab tsis tu ncua, thiab piav qhia lawv li nkhaus, uas tau tshwm sim ntawm qhov screen.
Oscilloscopes muaj ntau yam kev siv. Nws tuaj yeem hloov cov teeb liab uas tsis pom ntawm qhov muag liab qab rau hauv cov duab. Peb tuaj yeem txheeb xyuas qhov kev hloov pauv ntawm ntau lub teeb liab thiab cov ntaub ntawv raws li ntsuas lub teeb liab waveform.
Oscilloscope muaj ntau lub luag haujlwm thiab cov ntawv qhia zaub mov, thiab yuav tsum muaj qee theem ntawm kev paub yooj yim siv.
Multimeters muab faib ua ob hom: analog thiab digital.
Lub pointer ntawm analog meter swings flexibly, ua rau nws yooj yim los txiav txim cov kev hloov hauv Circuit Court.
Lub ntsuas hluav taws xob digital muaj cov lus teb ceev ceev, nyeem tau yooj yim, thiab me me parallax.
Lub multimeter ntse ntsuas DC cov cim qhia thiab qis -frequency AC signals nrog qhov raug siab. Rau feem ntau AC thiab cov teeb liab digital, lawv tsuas tuaj yeem kuaj pom siv oscilloscope. Vim lub oscilloscope lub peev xwm los tso saib ntau yam teeb liab waveforms pom nyob rau hauv hluav taws xob circuits ntawm lub oscilloscope raj, tib neeg muaj peev xwm txiav txim siab seb lub Circuit Court puas zoo li qub thaum lub sij hawm tu thiab Circuit Court debugging.
Nyob rau hauv circuits, tshwj xeeb tshaj yog nyob rau hauv tsis muaj zog hluav taws xob circuits, hluav taws xob signals yuav complex, random, thiab ib ntus. Hauv qhov no, ib qho oscilloscope tuaj yeem siv los txheeb xyuas cov yam ntxwv ntawm lub teeb liab thiab kwv yees nws cov hluav taws xob tsis zoo. Lub multimeter tsuas tuaj yeem ntsuas qhov ntsuas hluav taws xob tsis tu ncua ntawm- lub xeev cov teeb liab hluav taws xob, uas tsis yooj yim rau kev ntsuas thiab tshuaj xyuas cov teeb meem hluav taws xob nyuaj. Lub multimeter yog tsim los ntsuas ob qho tib si cov kab muaj zog tam sim no thiab qee qhov tsis muaj nyob hauv cov kab tsis muaj zog tam sim no. Oscilloscopes tau siv dav hauv cov hluav taws xob hluav taws xob, thiab tsis tshua haum rau siab -voltage circuits.
