Yuav ua li cas calibrate ib tug multimeter?
A: Zoo li lwm yam ntsuas ntsuas, lub multimeter yog ntsuas los ntawm cov chaw tsim khoom thaum nws tawm hauv lub hoobkas, yog li yog tias tsis muaj teeb meem loj, thov tsis txhob kho nws ntawm qhov xav tau. Lub taub hau ntawm lub tshuab hluav taws xob tam sim no feem ntau yog voltmeter, yog li thaum koj xav ntsuas lwm lub zog, koj yuav tsum xub kho DC voltage iav, uas yog hu ua cov iav yooj yim los ntawm kev lag luam sab hauv. Txhua lub iav thiab txhua txoj haujlwm (tshwj tsis yog cov iav tiv thaiv) tuaj yeem tawm ntawm kev sib tw. Feem ntau, multimeter yuav teeb ib lub potentiometer (xws li cov ntaub ntawv DC voltage) lossis ntau lub potentiometers (xws li cov ntaub ntawv kub) hauv txhua qhov haujlwm, thiab qee qhov tsis muaj potentiometer (xws li cov ntaub ntawv tsis kam). Yog hais tias muaj ib lub potentiometer, nws yog ib qho yooj yim mus lis, nkag mus rau lub teeb pom kev, thiab ces kho nws ncaj qha; Yog tias tsis muaj potentiometer, nws yuav tsis tawm ntawm kev sib tw.
