Multimeter, muab faib ua digital multimeter thiab pointer multimeter, yog ib qho tseem ceeb ntsuas ntsuas hauv hluav taws xob hluav taws xob thiab lwm yam haujlwm. Nws feem ntau yog siv los ntsuas qhov voltage, tam sim no thiab tsis kam ua lub hom phiaj tseem ceeb. Txawm hais tias digital lossis ib txwm muaj, lawv ob leeg ua lub luag haujlwm tseem ceeb hauv kev ntsuas, tab sis dab tsi yog qhov zoo thiab qhov tsis zoo ntawm ob?
Pointer Multimeter:
1. Tus pointer multimeter yog qhov ntsuas tus nqi nruab nrab, uas muaj qhov ntsuas kev nyeem ntawv zoo thiab pom tseeb.
2. Lub pointer multimeter feem ntau tsis muaj lub tshuab hluav taws xob sab hauv, yog li kev ua haujlwm sab hauv me me.
3. Vim lub me me nyob rau hauv tsis kam ntawm tus pointer multimeter thiab siv cov discrete Cheebtsam los tsim ib tug shunt thiab voltage divider circuit, zaus cov yam ntxwv tsis sib xws.
4. Cov qauv sab hauv ntawm lub pointer multimeter yog qhov yooj yim, yog li tus nqi qis dua, kev ua haujlwm tsawg dua, kev saib xyuas yooj yim, thiab lub peev xwm overcurrent thiab overvoltage muaj zog.
5. Cov zis voltage thiab tam sim no ntawm tus pointer-type multimeter yog siab, uas tuaj yeem kuaj tau yooj yim thyristors, lub teeb-emitting diodes, thiab lwm yam.
Digital Multimeter:
1. Digital multimeter yog ib qho cuab yeej tam sim no. Nws yuav siv ib qho piv txwv txhua txhua 0.3 vib nas this los tso saib cov txiaj ntsig ntsuas, thiab cov txiaj ntsig kev nyeem ntawv tsis yooj yim npaum li hom pointer.
2. Kev tiv thaiv sab hauv ntawm cov digital multimeter tuaj yeem ua kom loj vim yog siv sab hauv ntawm kev ua haujlwm amplifier Circuit Court, uas ua rau muaj kev cuam tshuam rau hauv Circuit Court hauv kev sim me me thiab qhov ntsuas qhov tseeb dua.
3. Digital multimeter txais ntau yam oscillation amplification, zaus faib, tiv thaiv thiab lwm yam circuits, yog li nws muaj ntau yam haujlwm.
4. Vim hais tias cov qauv sab hauv ntawm cov digital multimeter siv cov kev sib txuas sib txuas, lub peev xwm dhau qhov tsis zoo, thiab feem ntau nws nyuaj rau kho tom qab kev puas tsuaj.
5. Cov zis hluav taws xob ntawm cov digital multimeter yog qhov tsawg (feem ntau tsis tshaj 1 volt), uas tsis yooj yim rau kev sim ntawm qee yam khoom siv nrog cov yam ntxwv tshwj xeeb, xws li thyristors, lub teeb-emitting diodes, thiab lwm yam.
Yog li ntawd, los ntawm kev sib piv saum toj no, peb paub qhov zoo thiab qhov tsis zoo ntawm digital multimeters thiab ib txwm siv multimeters. Yog li ntawd, thiaj li yuav zoo dua noj cov multimeter, tus editor pom zoo tias rau beginners yuav tsum tau siv ib tug analog multimeter. , uas tuaj yeem pab cov kws tshawb fawb tshiab nyeem cov ntaub ntawv zoo dua thiab paub txog kev siv.
