Multimeter voltage ntsuas kev txawj: multimeter voltage ntsuas cov kauj ruam thiab ceev faj
1. Cov txheej txheem thiab cov kauj ruam ntawm kev ntsuas hluav taws xob nrog multimeter
Ua ntej tshaj plaws, qhov hloov pauv yuav tsum tau ua raws li tsib lub zog cim nrog V (AC voltage yuav tsum tau ua raws li AC voltage iav, thiab DC voltage yuav tsum tau ua raws li DC voltage iav thaum kuaj DC voltage).
Qhov thib ob, thaum ntsuas qhov voltage, tus cwj mem ammeter yuav tsum txuas nrog lub voj voog hauv kev sim. Raws li qhov kwv yees tus nqi ntawm Circuit Court nyob rau hauv kev sim, xaiv ib qho chaw tsim nyog. Tus nqi siab tshaj plaws ntawm txhua lub roj teeb qhuav yog 1.5V, yog li nws tuaj yeem muab tso rau hauv 5V ntau yam. Lub sijhawm no, 500 ntawm qhov ntsuas tag nrho ntawm txhais tes ntawm lub vaj huam sib luag yuav tsum tau nyeem raws li 5. piv txwv li scaled los ntawm ib qho ntawm 100. Yog tias tus pointer nyob ntawm 300 nplai, nws yuav raug nyeem raws li 3V. Nco ntsoov tias qhov ntsuas tus nqi ntawm qhov ntxeev ntawm qhov hloov pauv yog tus nqi sib thooj ntawm kev nyeem tag nrho ntawm tus pointer ntawm lub taub hau 'meter'. Thaum nyeem cov 'meter', koj tsuas yog yuav tsum tau hloov nws raws li kev nyeem tus nqi tiag tiag. Tsuas yog rau qhov kev tiv thaiv ntau yam, txhua qhov kev hloov pauv hloov tau tuaj yeem nyeem cov txiaj ntsig ntsuas hauv txoj kev no.
Thaum kawg, hauv qhov kev ntsuas tiag tiag, thaum kwv yees tus nqi ntawm qhov ntsuas qhov ntsuas tsis tuaj yeem txiav txim siab, qhov hloov pauv tuaj yeem hloov mus rau qhov siab tshaj plaws ua ntej, thiab tom qab ntawd qhov ntau tuaj yeem txo qis mus rau ib qho chaw tsim nyog. Ua tib zoo saib xyuas qhov zoo thiab qhov tsis zoo polarity thaum ntsuas DC voltage. Yog tias qhov kev xeem coj tau thim rov qab, cov koob xeem yuav thim rov qab. Yog tias koj tsis paub qhov zoo thiab qhov tsis zoo ntawm lub voj voog, koj tuaj yeem tsim qhov ntau ntawm Wantian meter mus rau qhov siab tshaj plaws, sim nws sai sai ntawm lub voj voog hauv kev sim, thiab saib seb tus cwj mem deflects, koj tuaj yeem txiav txim qhov zoo. thiab tsis zoo polarity.
2. Cov teeb meem xav tau kev saib xyuas thaum ntsuas qhov voltage nrog multimeter
1. Ua ntej siv lub tshuab multimeter, "txhim kho xoom xoom" yuav tsum tau ua ua ntej, uas yog, thaum tsis muaj hluav taws xob ntsuas, ua tus pointer ntawm multimeter taw tes rau txoj hauj lwm ntawm xoom voltage lossis xoom tam sim no.
2. Nyob rau hauv tus txheej txheem ntawm kev siv lub multimeter, tsis txhob kov cov hlau ib feem ntawm kev xeem txhuas nrog koj ob txhais tes, yog li ntawd nyob rau hauv ib tes, qhov tseeb ntawm kev ntsuas yuav tau guaranteed, thiab ntawm qhov tod tes, tus kheej kev nyab xeeb kuj muaj. yuav lav.
3. Thaum ntsuas qee qhov hluav taws xob, nws tsis tuaj yeem hloov lub zog thaum ntsuas, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis tam sim no loj. Txwv tsis pub, lub multimeter yuav puas. Yog tias koj xav tau hloov lub zog, koj yuav tsum txiav tawm qhov kev xeem ua ntej, thiab tom qab ntawd ntsuas tom qab hloov lub zog.
4. Thaum siv lub multimeter, nws yuav tsum tau muab tso rau kab rov tav kom tsis txhob ua yuam kev. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau zam kom tsis txhob muaj kev cuam tshuam ntawm sab nraud magnetic teb ntawm lub multimeter.
5. Tom qab siv lub multimeter, qhov hloov pauv yuav tsum tau muab tso rau hauv qhov siab tshaj plaws ntawm AC voltage. Yog tias nws tsis siv sijhawm ntev, lub roj teeb hauv lub tshuab hluav taws xob yuav tsum tau muab tshem tawm los tiv thaiv lub roj teeb ntawm corroding lwm yam khoom hauv lub ntsuas.
Lub multimeter tuaj yeem siv tsis tau tsuas yog los ntsuas qhov tsis kam ntawm cov khoom yuav tsum tau ntsuas, tab sis kuj ntsuas AC thiab DC voltages thiab DC voltage.
Txawm hais tias qee qhov multimeters tuaj yeem ntsuas qhov tseem ceeb ntawm cov transistors thiab cov capacitance ntawm capacitor. Los ntawm: Electrician World
Qhia cov multimeter los ntawm ob yam ntawm cov kev paub yooj yim ntawm multimeter thiab kev txawj ntsuas qhov voltage nrog lub multimeter, thiab pab txhua tus paub cov kev txawj ntse ntawm multimeter.
