Yuav ua li cas kho lub zog hloov hluav taws xob siv lub oscilloscope, uas txoj kev
Feem ntau hais lus, hauv av ntawm kev sib txuas hloov hluav taws xob muaj ob, uas yog "kub av" thiab "kub av". Siv lub voj voog nyob hauv daim duab 1 ua piv txwv, "◇" hauv daim duab sawv cev rau "kub av", qhov av no yog av ntawm thawj sab ntawm lub zog hloov hluav taws xob, thiab cov khoom siv hluav taws xob txuas nrog "kub. av" txuas nrog lub hauv paus phaj yog hu ua "kub puag phaj"; lub "sab sauv" nyob rau hauv daim duab sawv cev rau "kub puag phaj"; lub "sab sauv" hauv daim duab sawv cev rau "kub puag phaj". Lub "sab sauv" nyob rau hauv daim duab qhia tias "txias hauv av", qhov av no yog av ntawm ob sab ntawm lub zog hloov hluav taws xob, thiab cov load txuas nrog lub phaj hauv qab txuas nrog lub "txias hauv av" yog hu ua "kub av". . Cov av no yog cov av ntawm ob sab ntawm cov khoom siv hluav taws xob hloov hluav taws xob, uas txuas nrog lub nra, thiab lub hauv paus phaj txuas nrog "txias hauv av" yog hu ua "txias puag phaj".
Qhov tseem ceeb sib txawv ntawm "kub av" thiab "kub av" yog nyob rau hauv lub zero-potential reference point ntawm lub tshuab puag phaj thiab cov hluav taws xob daim phiaj nrog los yog tsis muaj "direct hluav taws xob kev twb kev txuas". Muaj kev sib txuas ncaj qha ntawm hauv av yog "kub av", lub tshuab "kub av" rau lub ntiaj teb muaj qhov hluav taws xob ntawm 100 volts, yog tias koj yuam kev ntawm lub tshuab "kub av" thiab "kub av" nrog lub Yog tias koj tsoo lub "kub av" hauv lub tshuab thiab cov khoom txuas nrog "kub av", nws yuav raug kev txom nyem los ntawm hluav taws xob poob siab, lossis txawm tias muaj kev phom sij rau lub neej; ntawm qhov tsis sib xws, "cov av txias" thiab daim phiaj siv hluav taws xob tsis muaj "kev sib txuas hluav taws xob ncaj qha", kov lub "qhov txias" nrog koj txhais tes tsis yog lub tswv yim zoo. Ntawm qhov tsis sib xws, "cov av txias" tsis muaj "kev sib txuas hluav taws xob ncaj qha" nrog rau daim phiaj siv hluav taws xob, thiab kov lub "txias hauv av" thiab cov khoom txuas nrog "qhov txias" los ntawm txhais tes feem ntau yuav tsis ua rau hluav taws xob poob siab.
Rau series hloov fais fab mov, tsuas yog ib qho "kub av", uas yog hais tias, lub hauv paus thiab theem nrab ntawm lub series hloov fais fab mov yog tib av, tag nrho rau "kub av". Vim hais tias lub LCD saib los ntawm cov teeb liab cable ncaj qha txuas nrog lub computer host, yog li ntawd, lub LCD saib switching fais fab mov tsis tuaj yeem siv nyob rau hauv series switching power supply, txwv tsis pub, lub computer host yuav raug them, uas yog tsis tso cai.
Cov teeb meem yuav tsum tau sau tseg hauv kev siv:
1, siv tus thawj fais fab qaum ntawm oscilloscope;
2, paub meej tias qhov ruaj khov ntawm daim phiaj hluav taws xob. Thaum muaj cov khoom siv hluav taws xob muaj zog nkag mus rau hauv daim phiaj hluav taws xob, tua lub oscilloscope ua ntej, tshem tawm cov hlua hluav taws xob, thiab siv nws tom qab daim phiaj hluav taws xob ruaj khov;
3, Thaum hloov ntawm oscilloscope: Plug rau hauv AC fais fab qaum ua ntej, thiab tom qab ntawd nias lub hwj huam khawm hloov ntawm oscilloscope;
Thaum hloov tawm: hloov lub oscilloscope los ntawm nias lub khawm hloov pauv ua ntej, thiab tom qab ntawd tshem tawm cov hlua hluav taws xob AC;
4, xyuam xim rau kev siv cov cuab yeej ib puag ncig, ntxuav cov plua plav tsis tu ncua.
