Yuav ua li cas los txheeb xyuas lub multimeter?
Lub multimeter yog tib yam li lwm yam ntsuas. Thaum nws tawm hauv lub Hoobkas, cov chaw tsim khoom tau kho nws, yog li yog tias tsis muaj teeb meem loj, thov tsis txhob kho nws ntawm qhov xav tau. Lub taub hau ntawm lub multimeter tam sim no feem ntau yog voltmeter, yog li thaum koj xav calibrate lwm lub zog, koj yuav tsum xub kho DC voltage iav. Cov iav no yog qhov kev lag luam hu ua cov iav yooj yim. Txhua lub iav thiab txhua txoj haujlwm (tshwj tsis yog cov iav tiv thaiv) tej zaum yuav tsis raug. Feem ntau, ib tug multimeter yuav teem ib lub potentiometer (xws li DC voltage file) los yog ntau lub potentiometers (xws li cov ntaub ntawv kub) rau txhua txoj haujlwm, thiab qee qhov tsis muaj potentiometer (xws li cov ntaub ntawv tsis kam). Nws yog ib qho yooj yim los tuav nrog lub potentiometer, nkag mus rau qhov teeb meem nrhiav pom, thiab tom qab ntawd kho nws ncaj qha; yog tias tsis muaj potentiometer, feem ntau nws yuav tsis raug, yog tias qhov tsis raug, nws yuav tshwm sim los ntawm kev puas tsuaj rau cov twj paj nruag lossis kev sib cuag tsis zoo ntawm cov kab.
