Qhov zoo thiab qhov tsis zoo ntawm digital multimeter thiab pointer multimeter
Multimeters, muab faib ua digital multimeters thiab pointer multimeters, 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. Nws yog ib qho kev ntsuas ntau yam thiab ntau yam ntsuas. Txawm hais tias nws yog digital lossis ib txwm muaj, lawv txhua tus ua lub luag haujlwm tseem ceeb hauv kev ntsuas, tab sis qhov zoo thiab qhov tsis zoo ntawm ob qhov sib piv yog dab tsi?
Pointer Multimeter:
1. Lub pointer multimeter yog ib qho nruab nrab meter, uas muaj ib qho intuitive thiab vivid nyeem ntawv qhia.
2. Feem ntau, tus pointer multimeter tsis muaj amplifier nyob rau hauv, yog li lub internal kuj tseem 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 Court, 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 ntawm tus pointer multimeter yog qhov siab, thiab tam sim no kuj loj, uas tuaj yeem yooj yim sim thyristors thiab lub teeb-emitting diodes.
Digital Multimeter:
1. Digital multimeter yog ib qho ntsuas ntsuas tam sim. Nws yuav siv ib qho piv txwv txhua 0.3 vib nas this los tso saib cov txiaj ntsig ntsuas. Nws tsis yooj yim los nyeem cov txiaj ntsig raws li hom pointer.
2. Txij li cov digital multimeter siv lub tshuab hluav taws xob ua haujlwm sab hauv, qhov kev tiv thaiv sab hauv tuaj yeem ua rau loj heev, uas ua rau muaj kev cuam tshuam rau hauv Circuit Court hauv kev sim me me thiab qhov ntsuas qhov tseeb yog siab dua.
3. Cov multimeter digital siv ntau yam oscillation amplification, zaus faib, kev tiv thaiv thiab lwm yam circuits hauv, yog li nws muaj ntau yam haujlwm.
4. Txij li cov qauv sab hauv ntawm cov digital multimeter feem ntau siv cov kev sib xyaw ua ke, lub peev xwm dhau los kuj tsis zoo, thiab feem ntau tsis yooj yim 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), thiab nws tsis yooj yim rau kev sim qee yam khoom siv nrog cov yam ntxwv tshwj xeeb, xws li thyristors thiab lub teeb-emitting diodes.
