Daws daws teeb meem, tus lej ntawm cov lej thiab khoom loj
Kev daws teeb meem yog hais txog lub peev xwm ntawm ib tug multimeter kom paub qhov txawv ntawm cov cim me me thaum ntsuas ntsuas. Paub txog kev daws teeb meem ntawm kev sib raug zoo ntawm kev ua kom koj xav paub seb nws puas tuaj yeem kuaj seb puas hloov pauv me me hauv lub teeb liab ntsuas. Piv txwv li, yog tias cov digital motimeter muaj kev daws teeb meem ntawm 4 v, nws tuaj yeem pom qhov hloov ntawm 1 MV (1/1000 V).
Yog tias koj yuav tsum ntsuas ib ntev li 1/4 nti (lossis 1 millimeter), koj yuav tsis yuav ib tus pas ntsuas nrog qhov tsawg tshaj plaws ntawm 1 nti (lossis 1 ib xo). Yog tias qhov ntsuas kub ib txwm yog 98.6 degrees Fahrenheit, tus pas ntsuas kub uas muaj peev xwm tsuas yog ntsuas cov qib tsis muaj txiaj ntsig. Koj xav tau tus pas ntsuas kub nrog kev daws teeb meem ntawm 0.1 degree.
Cov lus cog lus "me ntsis" thiab "tus lej" yog siv los piav qhia txog kev daws teeb meem ntawm kev sib xyaw. Ntau tus tuaj yeem ua pawg raws li tus lej ntawm cov lej lossis cov khoom ntim ntawm cov digital motimeter.
Ib tug 3½ {{- Digit MULLICALS tuaj yeem tso peb tus lej tag nrho (0 txog 9) thiab tsuas yog tso tawm ib qho "1" lossis tso tawm sab laug). Cov zaub daws teeb meem ntawm ib qho 3½- Digit Multimeter yog txog 1,999 tus lej. Cov zaub daws teeb meem ntawm ib qho 4½ {{{{{{{}} Digit Multimeter yog txog 19,999 tus lej. Piv nrog "me ntsis", siv "tus lej" tuaj yeem piav qhia qhov tseeb dua ntawm kev daws teeb meem ntawm kev sib raug zoo ntawm kev sib raug zoo. Tam sim no, kev daws teeb meem ntawm ib tug 3½-} lej lej multimeter tej zaum yuav yog li 3,200, 4,000 lossis 6,000 tus lej.
Rau qee qhov kev ntsuas, ib qho 3,200-tus lej sib sau tuaj yeem muab cov kev daws teeb meem zoo dua. Piv txwv li, yog tias koj xav ntsuas qhov hluav taws xob ntawm 200 60 V. Ua ntej qhov ntsuas hluav taws xob tsis tau mus txog 0.1 V, qhov kev daws teeb meem no yog tib yam li cov lej nqi ntau dua 20,000 tus lej ntxiv.
