Multimeter ntsuam xyuas thiab raug
Puas yog qib thiab qhov tseeb ntawm multimeter yog tib yam? Thaum xam qhov siab tshaj qhov txheeb ze yuam kev, koj tsuas paub yuav ua li cas xam cov precision?
Qib ntawm qhov tseeb ntawm cov ntaub ntawv ntsuas, hu ua "precision level", qhia raws li qhov feem pua ntawm qhov yuam kev ntxiv lossis rho tawm.
Piv txwv li, ib theem ntawm 2.5 txhais tau tias nws qhov kev ua yuam kev yog 2.5 feem pua. Lub multimeter ntau lub zog feem ntau muaj qhov sib txawv ntawm qhov tseeb. Piv txwv li, DC iav thiab ohm iav yog av 1.5, thiab AC iav tej zaum yuav av 3.0, uas yog cim rau ntawm lub xov tooj ntawm lub moos.
