Piav qhia luv luv piav qhia txog kev ua haujlwm theem pib ntawm kev siv ntau ntau yam kev ntsuas tiv thaiv tsis kam
1. Ua ntej, txuas cov kev sim. Kev xaiv ntawm pululation tuaj yeem yog tus pointer lossis cov digital. Ntxig cov kev sojntsuam liab rau hauv V ω ntau thiab cov kev sojntsuam dub rau hauv com thaum xaus kom ntseeg tau tias qhov kev haus kom zoo.
2. Rotate lub multimatai iav kom ntsuas tsis kam. Yog tias koj tsis paub tseeb ntawm tus nqi tiv, koj yuav tsum xub muab cov khoom loj tshaj plaws mus rau qhov ntau tshaj plaws rau cov khoom loj me, yog li ntawd cov ntsuas tes taw qhia tsawg kawg 1/2 ntawm tag nrho cov nplai. Tom qab xaiv cov khoom tsim nyog tshaj plaws, kov ob qhov kev sim ua kom tus pointer taw rau xoom. Yog hais tias tus pointer deviates los ntawm xoom, kho qhov "xoom hloov" pob qhov rooj kom cov pointer rov qab los ua kom ntsuas tau.
3. Txuas ob ntu ntawm lub resistor, txuas cov kev sim cia li tsis muaj qhov sib txawv ntawm lossis tsis zoo, thiab nco ntsoov ua kom muaj kev sib cuag zoo.
4. Nyeem cov ntaub ntawv tso tawm ntawm pululation. Yog tias tsis muaj cov ntaub ntawv tshwm nyob rau ntawm multimeter, nws yog qhov ua tau hais tias lub resistor tau tawg. Tau kawg, tseem muaj qhov ua tau tias qhov ntau yog tsis txaus thiab xav tau hloov.
5. Nce qhov ntau. Yog tias tseem tsis muaj ntaub ntawv, nws tsuas yog qhia tau tias lub resistor tau tawg. Yog tias muaj cov ntaub ntawv tso tawm, ua tib zoo mloog ntxiv cov khoom ntawm cov iav.
Tus txheej txheem tseem ceeb ntawm kev sib ntxiv:
Nws siv rhiab heev Magneto Fais DC Ammeter (microampere meter) thaum ntsuas lub taub hau. Thaum ib qho kev hla me me dhau los ntawm lub ntsuas, yuav muaj kev qhia tam sim no. Tab sis lub taub hau meter tsis tuaj yeem hla dhau los yog txo qhov kev tsim tawm los ntawm kev ntsuas lub taub hau lossis ntsuas qhov ntsuas qhov tam sim no, hluav taws xob, thiab kev tawm tsam, thiab kev tawm tsam, thiab kev tawm tsam, thiab kev tawm tsam, thiab kev tawm tsam, thiab kev tawm tsam, thiab kev tawm tsam, thiab kev tawm tsam, thiab kev tawm tsam thiab kev tawm tsam.
Kev ceev faj rau kev siv ntau tshaj:
1. Ua ntej siv compultimeter, nws yog ib qho tsim nyog los ua "kev siv kho tshuab txhais tau tias thaum tsis muaj lub zog ntsuas, qhov kev ntsuas tus pointerage lossis xoom txoj haujlwm tam sim no.
2. Thaum lub sijhawm siv ntawm kev siv ntau, tsis txhob kov cov hlau ib feem ntawm kev sojntsuam nrog koj txhais tes. Qhov no ua kom pom tseeb kev ntsuas kev nyab xeeb thiab kev nyab xeeb ntawm tus kheej.
3. Thaum ntsuas ib qho hluav taws xob tsawg, nws tsis yog xav ua haujlwm hloov pauv tib lub sijhawm, tshwj xeeb yog thaum ntsuas cov hluav taws xob ntau lossis siab tam sim no. Txwv tsis pub, nws yuav ua rau kev puas tsuaj rau multometer. Yog tias koj xav tau hloov lub zog, txiav cov kev sojntsuam ua ntej thiab tom qab ntawd ntsuas kev ntsuas tom qab hloov zog.
4. Thaum siv multimeter, nws yuav tsum tau muab kab rov tav kom tsis txhob raug. Nyob rau tib lub sijhawm, nws tseem yog ib qho tseem ceeb kom tsis txhob muaj cov kab sib sib sib nqus ntawm sab nraud ntawm cov multimeter.
