Multimeter's Accuracy Class
Qhov tseeb ntawm multimeter feem ntau yog qhia los ntawm qhov tseeb, uas qhia txog qhov loj ntawm qhov yuam kev ntawm qhov ntsuas. Qhov siab dua qhov tseeb, qhov me me qhov ntsuas qhov yuam kev.
Qhov tseeb ntawm multimeter muab faib ua 7 theem: 0.1, 0.2, 0.5, 1.0, 1.5, 2.5, 5.{ {14}}. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm kev lag luam ntsuas, kuv lub teb chaws muaj peev xwm tsim tau 0 05- theem qhia cov cuab yeej.
Qib raug qhia txog qhov loj ntawm qhov yuam kev ntawm lub 'meter'. Qhov tseeb ntawm cov khoom siv hauv tsev MF18 multimeter rau ntsuas DC voltage (DC V), DC tam sim no (DC A) thiab tsis kam (Ω) yog tag nrho 1.0, uas tuaj yeem siv hauv chav kuaj.
Lub 500-hom multimeter, uas tseem siv dav tam sim no, yog 2.5- ntsuas ntsuas. Nws yuav tsum tau muab sau tseg tias vim muaj kev cuam tshuam ntawm circuits xws li voltage dividers, shunts, thiab rectifiers, qhov yuam kev ntawm txhua lub iav ntawm tib lub multimeter tsis zoo ib yam.
Qhov tseeb ntawm qhov dav dav multimeter feem ntau yog 2.5 (xws li MF47, MF30, thiab lwm yam). Lub multimeter qhov raug yog sawv cev ntawm lub dial raws li qhia.
