Dab tsi zoo dua analog multimeters thiab digital multimeters muaj dua ib leeg?
Tus pointer multimeter yog qhov ntsuas tus nqi nruab nrab Nws yog intuitive Visual nyeem ntawv qhia
(Feem ntau, tus nqi nyeem ntawv yog ze ze rau lub pointer viav vias lub kaum sab xis, yog li nws yog qhov yooj yim heev)
Ib qho digital multimeter yog ib qho kev ntsuas tam sim no Nws yuav siv sij hawm ib qho qauv txhua 0.3 vib nas this los tso saib cov txiaj ntsig ntsuas qee zaus cov txiaj ntsig ntawm txhua qhov piv txwv tsuas yog zoo ib yam Tsis zoo ib yam Qhov no tsis yooj yim rau kev nyeem cov txiaj ntsig raws li cov txheej txheem taw qhia.
Ib tug pointer multimeter feem ntau tsis muaj lub amplifier nyob rau hauv Yog li ntawd lub internal kuj kuj yog me me Piv txwv li, lub MF-10 qauv muaj ib tug DC voltage rhiab heev ntawm 100 kiloohms ib volt Qhov no yuav xam tau tias yog ib tug zoo nkauj tus DC voltage rhiab heev ntawm MF-500 qauv yog 20 kiloohms ib volt.
Cov multimeter digital siv lub tshuab hluav taws xob ua haujlwm hauv lub cev Lub zog sab hauv tuaj yeem ua kom loj heev Feem ntau ntawm 1M euros lossis ntau dua (piv txwv li tuaj yeem ua tiav siab dua) Qhov no ua rau muaj kev cuam tshuam rau qhov ntsuas hluav taws xob me me siab ntsuas qhov tseeb.
Pointer multimeters muaj qhov tsis kam sab hauv thiab feem ntau siv cov khoom sib cais los tsim cov shunt thiab voltage divider circuits Yog li cov yam ntxwv zaus tsis sib xws (piv rau cov digital) Cov yam ntxwv zaus ntawm tus pointer multimeter kuj zoo dua.
Tus pointer hom multimeter muaj ib qho yooj yim sab hauv cov qauv, yog li tus nqi kuj tsis tshua muaj tsawg functionality Ib qho yooj yim kom muaj zog overcurrent thiab overvoltage muaj peev xwm.
Cov multimeter digital siv ntau yam oscillations thiab amplifiers internally division Cov kev tiv thaiv Circuit Court muaj ntau lub zog, xws li ntsuas qhov kub thiab txias Frequency (nyob rau hauv ib tug qis ntau yam) Capacitors, inductors los yog ua ib tug teeb liab generator, thiab lwm yam
Vim yog kev siv cov kev sib xyaw ua ke hauv cov qauv sab hauv, lub peev xwm dhau los tsis zoo (Txawm li cas los xij, qee qhov tam sim no muaj kev hloov pauv tsis siv neeg, kev tiv thaiv tsis siv neeg, thiab lwm yam, tab sis kev siv ntau dua) Nws feem ntau tsis yooj yim kho tom qab kev puas tsuaj.
Cov zis hluav taws xob ntawm lub tshuab hluav taws xob digital yog qhov tsawg (feem ntau tsis tshaj 1 volt) Nws tsis yooj yim rau kev sim qee yam khoom siv hluav taws xob tshwj xeeb, xws li thyristors, lub teeb -emitting diodes, thiab lwm yam.
Cov zis voltage ntawm tus pointer multimeter yog qhov siab (suav nrog 10.5 volts, 12 volts, thiab lwm yam)
Tam sim no kuj loj (xws li MF-500 * 1 Euro ntau * nrog rau qhov siab tshaj plaws ntawm 100mA), uas ua rau nws yooj yim rau kev sim thyristors, lub teeb-emitting diodes, thiab lwm yam.
Rau beginners yuav tsum tau siv ib tug pointer multimeter
Rau cov tsis pib, ob hom twj paj nruag yuav tsum tau siv
