Yuav Ua Li Cas Xaiv Ntawm Ib Lub Handheld Multimeter thiab Benchtop Multimeter?
Ib qho digital multimeter yog ntau yam khoom siv hluav taws xob ntsuas nrog ntau cov duab thiab cov lus qhia tshwj xeeb, uas tuaj yeem dhau ntawm lwm yam ntsuas. Feem ntau cov khoom siv tes tuav thiab desktop multimeters. Yog li ntawd, thaum xaiv, koj yuav tsum xaiv ib tug handheld los yog desktop multimeter? Hnub no, Antai Testing yuav qhia rau koj:
Handheld digital multimeters feem ntau yog siv rau hauv - qhov chaw ib puag ncig uas muaj nuj nqis rau kev txav mus los thiab roj teeb lub zog. Nyob rau hauv ib puag ncig zoo li no, cov neeg siv tuaj yeem ntsuas qhov yooj yim voltage, tam sim no, thiab tiv thaiv sai thiab yooj yim thaum tsiv ntawm ib qho chaw mus rau lwm qhov. Rau cov ntawv thov no, kev daws teeb meem, qhov tseeb, kev ntsuas ceev, lossis kev sib txuas hauv computer tsis tseem ceeb npaum li roj teeb lub neej, kav ntev, thiab qhov loj me.
Desktop multimeters yog loj dua handheld multimeters vim hais tias lawv yog tsuas yog siv nyob rau hauv designer workstations los yog automation system xeem racks. Cov kws qhia txuj ci engineering, cov kws tshawb fawb, cov tsim khoom tsim khoom, thiab txhua hom kev sim engineers yog cov neeg siv cov duab multimeters. Rau cov neeg siv no, rhiab heev, qhov tseeb, ntau yam, kev ua haujlwm siab tshaj plaws, kev ntsuas ceev, thiab kev sib txuas rau tus kheej lub khoos phis tawj tseem ceeb dua.
Desktop digital multimeters muaj tag nrho cov yam ntxwv no, muab qhov kev daws teeb meem ntawm 5 thiab ib nrab ntawm cov khoom rau 8 thiab ib nrab ntawm cov khoom, siab tshaj qhov raug 3 thiab ib nrab ntawm cov khoom mus rau 4 thiab ib nrab cov khoom daws teeb meem ntawm tes multimeters. Lub rhiab heev ntawm desktop multimeters tuaj yeem ncav cuag qhov tsawg kawg nkaus ntawm 100nV, 0.1 µ Ω, thiab 1pA, thaum siab -kawg handheld multimeters muaj rhiab heev ntawm 10 µ V, 0.1 Ω, thiab 0.01 µ A. Lub DCV qhov tseeb ntawm multimeters yog 0%. 0.0025% DCV thiab qhov tseeb dua.
Desktop multimeters feem ntau yog siv rau kev ntsuas tsis siv neeg thiab xav tau kev sib txuas los tswj cov multimeter thiab xa / txais cov ntaub ntawv siv lub computer. Kev ntsuam xyuas tsis siv neeg feem ntau yuav tsum tau ntsuas ceev ceev thiab muaj peev xwm los ua piv txwv cov waveforms nyuaj, raws li qhia hauv daim duab hauv qab no. Yog tias txoj haujlwm ntawm tus kws kho mob yog ua kom lub tshuab hluav taws xob ua haujlwm, ces nws tsis xav tau cov haujlwm no. Thiab cov yam ntxwv ntawm lub desktop no yog qhov tseem ceeb rau cov kws tshawb fawb, cov kws tsim qauv, thiab cov kws tshaj lij kev sim.
