Qhov sib txawv tseem ceeb ntawm tus pointer thiab digital multimeters
Digital multimeter tshaj pointer multimeter nyob rau hauv kev ntsuas, kev nyeem ntawv qhov tseeb thiab rhiab heev yog siab dua, lub internal kuj yog loj, nyob rau hauv kev ntsuas ntawm voltage, digital ze rau qhov zoo tagnrho ntsuas tej yam kev mob. Nyob rau tib lub sij hawm lub digital multimeter ntsuas muaj nuj nqi ntau dua, xws li ntsuas lub peev xwm, ntsuas kub, zaus thiab lwm yam.
Thaum cov multimeter ntsuas cov txheej txheem dynamic, tus lej dhia, uas tsis tuaj yeem cuam tshuam cov txheej txheem hloov pauv zoo. Pointer multimeter tuaj yeem cuam tshuam qhov kev hloov pauv tas mus li thiab hloov pauv ntawm qhov ntau, thiab saib cov txheej txheem dynamic ntau intuitively.
Thaum ntsuas DC voltage lossis tam sim no, yog tias lub polarity ntawm pointer hom multimeter thim rov qab, tus pointer yuav thim rov qab, thaum hom digital tuaj yeem txheeb xyuas thiab tso saib cov polarity, xws li cov duab tsis zoo, muaj "-" kos npe rau pem hauv ntej. cov duab tsis zoo.
Thaum lub pointer multimeter yog siv los ntsuas qhov voltage thiab tam sim no tshaj qhov ntau, tus pointer yuav deviate mus rau txoj cai mus rau qhov txwv txoj hauj lwm, uas yog ib qho yooj yim rau kev puas tsuaj rau lub taub hau 'meter' los yog ua kom qhov tseeb yog tsawg. Cov multimeter digital qhia 1, qhia tias nws tawm ntawm qhov ntau, uas yog tib yam thaum ntsuas kev tiv thaiv.
Pointer multimeter raws li tus pointer thiab dial nyeem, yooj yim los tsim tib neeg yuam kev, thaum lub digital tshem tawm tib neeg kev ua yuam kev, tab sis cov digital multimeter muaj qhov cuam tshuam rau kev cuam tshuam, thiab digital jumps, txiav txim siab tus nqi digital ntawm qhov teeb meem, feem ntau coj tus nqi nruab nrab. , nyob rau hauv tej rooj plaub yuav tsum tau qhov tsawg kawg nkaus los yog siab tshaj tus nqi.
Nyob rau hauv qhov kev pom ntawm pointer multimeter thiab digital multimeter muaj lawv tus kheej zoo, yog li nws pom zoo tias ob lub rooj nrog qhov zoo tshaj plaws, feem ntau, lossis digital multimeter yog qhov zoo dua, ua haujlwm ntau dua, yuav tsum yog thawj qhov kev xaiv.
Pointer multimeter xaiv kev txawj:
Multimeter kab rov tav, ntsug, tiaj tus lub xeev muab tso rau ntawm lub pointer nyob rau hauv lub xoom txoj hauj lwm, qhia tau hais tias qhov tseeb ntawm lub multimeter yog siab dua, thiab ces ib co kuj, voltage ntsuas, saib seb cov hauj lwm ntawm cov ntaub ntawv yog zoo, npaum li cas yog, yog tias tsim nyog, koj kuj yuav tsum tau ua tib zoo saib ntawm phau ntawv qhia.
