Ib qho multimeter hauv tsev yuav pab koj txiav txim siab qhov hluav taws xob hauv qhov hluav taws xob, txheeb xyuas qhov tsim nyog ntawm lub roj teeb, thiab tseem paub seb qhov tam sim no nyob hauv qhov hluav taws xob nyob qhov twg. Yog lawm, ua qhov tsis muaj cov txuj ci tshwj xeeb tsis tsim nyog.
Nws yog qhov tsim nyog
- - multimeter;
- - kev txawj ntse hauv kev ua haujlwm nrog cov cuab yeej hluav taws xob.
Cov Lus Qhia
Kauj ruam 1
Siv cov kab xev xaim kom paub txog qhov hluav taws xob ntawm cov xaim, ntxiv rau kev tiv thaiv winding thiab tam sim no. Nrhiav cov cua ntsawj. Txhawm rau ua qhov no, teeb lub cuab yeej mus rau kev ntsuas tiv thaiv hom lossis hu. Txheeb xyuas cov pawg ntawm cov xov hlau hauv qhov cua. Ntswj cov xov tooj sib txuas ua ke, koj tuaj yeem paub lawv los ntawm kev tsis kam qis ntawm lawv.
Kauj ruam 2
Thov voltage rau cov xov hlau tuab. Koj yuav tsis ua kev hloov pauv, txawm hais tias muaj qee yam ua tsis yog. Yog tias koj ntshai tias hlawv cov hlau no, siv 6.3 V ntawm qhov tam sim no mus rau lwm cov xov hlau, ntsuas qhov ntsuas ntawm qhov hluav taws xob tuab. Nws tus nqi yuav tsum yog 220. Teem lub AC voltage ntsuas hom ntawm qhov multimeter.
Kauj ruam 3
Tom qab sib txuas, ntsuas qhov ntsuas ntawm lwm pab pawg lossis pawg ntawm cov xov hlau. Muaj cov ntawv ntawm daim ntawv ntsia hlau rau ntawm cov xov hlau, kos npe rau cov txiaj ntsig tau los ntawm lawv. Ntsuas cov tam sim no. Txhawm rau ua qhov no, ntawm multimeter, txav qhov kev sojntsuam los ntawm vr rau 10 A, ntsuas hauv khub ntawm cov xov hlau, qhov twg yog tus nqi tam sim no.
Kauj ruam 4
Xyuas cov xov hluav taws xob ntau. Ua ntej tshaj, tshawb xyuas lawv, piv txwv li, rau kev deformation ntawm daim plhaub yas. Yog tias nws tawg lossis yaj, ces cov xaim yuav tsum tau hloov. Sab nraud cov xov hlau tsis zoo ua tau lub ntsej muag tawm nrog ib tus multimeter. Cov cuab yeej no laij cov tsis kam ntawm cov hlau thiab muab piv nrog cov nqi tsim nyog tau txais
Kauj ruam 5
Teem lub multimeter rau 20K, muab ib tus pin rau txhua kawg ntawm qhov txuas. Tom qab ntawv, nyeem qhov muab tiv. Piv nrog rau qhov muaj peev xwm lees paub qhov tseem ceeb. Rau cov xov hluav taws xob hluav taws xob siab nrog cov tub ntxhais tooj liab, tus nqi no tuaj yeem nyob ntawm 1 txog 6.5K. Rau cov xov hlau muaj cov xaim hluav taws xob, qhov ntsuas no tuaj yeem yog los ntawm 2.2K txog 8K. Yog tias koj xaim cov xaim xov hluav taws xob nrog kev faib tawm tsis kam, tus nqi yog li ntawm 10K thiab 23K.
