Taw qhia rau kev tiv thaiv kev ceev faj rau kev ntsuas hluav taws xob muaj peev xwm nrog kev sib ntxiv
Ua ntej ntsuas kev ntsuas, nws yog qhov tsim nyog los txiav tawm lub zog thiab paug. Cov qauv ntawm kev rho tawm yog nrhiav cov khoom hlau xws li lub hau ntswj, tuav nws ntawm cov hlau ntawm insulating siv, thiab muab ob txhais ceg ntawm cov ntsuas ntsuas ntawm ob txhais ceg. Qhov ntsuas ntsuas ntsuas ntsuas yog ntsuas nrog cov digital motimeter, thiab tom qab ntawd tshem tawm cov capacitor. Ob txhais ceg tau tso rau hauv kev ntsuas ntsuas ntsuas lub twj tso tawm lossis lwm lub vijtsam LCD. Kev nyeem ntawv ruaj khov yog lub peev xwm ntawm lub ntsuas ntsuas ntsuas ntsuas. Yog kuaj pom, cov tshuaj tiv thaiv, cov kev tiv thaiv ntau ntawm cov taw tes ntau yam yuav siv tau rau kev ntsuas. Thaum ntsuas qhov ntsuas, lub peev xwm me me muaj peev xwm muab tso rau hauv Rx1k lossis Rx100 thaum ntsuas cov khoom siv ob txhais ceg, tus pointer deflecs clockwise. Tom qab ntawd, raws li lub capacitor tau raug them siab rau sab hauv, vim tsis muaj qhov ntws tawm tam sim no, tus pointer yuav tso tawm cov khoom noj tau zoo thiab rov qab mus rau infinity. Qhov loj dua lub kaum sab xis ntawm tus pointer, lub peev xwm loj dua. Thaum lub sij hawm deflection txheej txheem, tus pointer xav tau viav vias ntawm qhov ceev tsis tu ncua kom nws rov qab mus rau infinity, qhia tias lub capacitor tsis xau hluav taws xob. Yog hais tias tus pointer dheev qeeb qeeb los yog tsis rov qab los ntawm qee txoj haujlwm ntawm lub xov tooj, nws qhia tias lub capacitority nyob rau qee ntu. Yog tias thaum kawg qhia raws li infinity, nws qhia tau tias tsis muaj hluav taws xob lav. Txawm li cas los xij, qhov no tsuas yog txiav txim siab. Txhawm rau nrhiav tus nqi raug, nws yog ib qho tsim nyog los soj ntsuam cov yam ntxwv nrog lub peev xwm capacitchat meter, capacence tokter lossis oscilloscope. Qhov no ua tsis tau rau cov neeg zoo tib yam. muaj. Peev xwm capactracitors kuj tseem muaj fasand voltage, thiab tiv thaiv cov nqi hluav taws xob ntawm electrolytic capacitors feem ntau yog sau rau ntawm nws. Thaum xaiv cov ceramic ceracitors, nws yog ib qho tseem ceeb kom nco ntsoov tias qee tus tsis tau sau nws.
