Kev kho ntawm tus pointer ntawm Multimeter tsis rov pib dua
Tom qab siv lub multimeter rau ib lub sijhawm, nws tau pom tias tus pointer tsis tuaj yeem rov pib dua rau xoom, thiab qee zaum tus pointer yuav nyob ntawm qhov chaw deflected. Yog vim li cas yog tias rooj plaub ntawm multimeter yog ua los ntawm plexiglass. Txij li thaum cov hmoov av nyob rau saum npoo feem ntau so nrog tes los yog lwm yam flannelettes thaum siv, raws li lub sij hawm siv nce thiab cov xov tooj ntawm kev sib txhuam nce, cov ntaub ntawv tsim hluav taws xob zoo li qub yog nyiam, tshwj xeeb tshaj yog nyob rau lub caij nplooj zeeg thiab lub caij ntuj no thaum huab cua qhuav, yog li lub pointer yuav nyob ntawm ib qho chaw thaum ntsuas.
Thaum ntsib qhov tsis ua haujlwm ntawm tus ntsuas hluav taws xob electrostatic adsorption, koj tuaj yeem dilute 5 feem pua ntawm cov tshuaj bromogeramine (muaj nyob rau hauv cov khw muag tshuaj) nrog 30 feem pua ntawm cov dej distilled, thiab tom qab ntawd siv cov paj rwb los txhuam cov tshuaj npaj sib npaug ntawm sab hauv thiab sab nraud ntawm rooj plaub multimeter. Txhuam ib txheej, muab tso rau hauv qhov chaw uas muaj qhov kub ntawm 38 ~ 40 degree kom qhuav, thiab qhov txhaum tuaj yeem raug tshem tawm.
Nws tuaj yeem raug tshem tawm los ntawm kev ntxiv glycerin thiab ntsev kom tshem tawm cov hluav taws xob zoo li qub ntawm lub xov tooj.
