Cov khoom siv thiab xaiv cov hauv paus ntsiab lus rau cov neeg coob coob
Ib qho digital pulultimeter yog tam sim no feem ntau siv hom digital ntsuas. Nws lub ntsiab tseem ceeb yog qhov yog qhov yog qhov tseeb, ua tiav kev sim ua kom nrawm, muaj peev xwm sim nrawm, thiab kev siv hluav taws xob tsis muaj zog, thiab kev sib txuas tsis muaj zog, thiab kev sib txuas tsis muaj zog, thiab kev tsis muaj zog thiab yooj yim. Txij li thaum xyoo 1990, cov multiver digital tau nrawm thiab siv cov khoom siv hluav taws xob ua niaj hnub no, thiab maj mam hloov cov tsoos analog (piv txwv li pointer) multipeters) multimeters.
Digital multiveters, tseem hu ua cov multiveters digital (dmms), muaj ntau hom hom thiab cov qauv. Txhua tus neeg ua haujlwm hluav taws xob cia siab tias yuav muaj cov digital zoo tagnrho. Muaj ntau cov hauv paus ntsiab lus rau kev xaiv digital motimeter, thiab qee zaum nws kuj yuav txawv ntawm ib tus neeg mus rau lwm tus. Tab sis rau Handheld (Pocket loj) Cov neeg muaj kev tiv thaiv digital, kev tiv thaiv zoo nkauj, muaj zog ua kom muaj zog, kev siv hluav taws xob yooj yim, qhov chaw tsis muaj zog, cov nqi yooj yim, nqe lus yooj yim, ntsuas nqi, thiab lwm yam.
Cov ntsuas ntsuas tseem ceeb, tso cov lej, thiab tso saib cov yam ntxwv ntawm cov digital motimeter
Tus lej zaub ntawm cov digital motimeter feem ntau {{{{{}} {{2} {2}} / 2 tus lej. Muaj ob lub ntsiab cai rau kev txiav txim rau cov zaub lej digital: ua ntej, tus lej uas tuaj yeem tso txhua tus lej ntawm {4}} yog cov lej lej zauv; Qhov thib ob taw tes yog tias tus nqi ntawm cov zauv feem yog ua raws cov lej siab tshaj plaws hauv qhov muaj txiaj ntsig tshaj plaws uas yog cov lej. Thaum ntsuas txhua yam, tus nqi yog 2 {13}}} {19}} 0, qhia tias qhov ntsuas muaj 3 tus lej. Cov lej ntawm cov fractional yog 1, thiab nws yog hu ua {{{9}, uas yog nyeem raws li "peb thiab ib nrab lej". Tus lej siab tshaj plaws tsuas yog tso saib 0 lossis 1 (0 feem ntau tsis tso tawm). Tus lej siab tshaj plaws ntawm 3 2 / 3 tus lej (muaj qhov ntau tshaj plaws ntawm 0 3 thiab 2% kev ntsuas tus nqi "
Universal digital multimeters generally belong to handheld multimeters with 3 1/2 digit displays, while 4 1/2 and 5 1/2 digit (below 6 digits) digital multimeters are divided into handheld and desktop types. Ntau tshaj li {{6 1 / 2 tus lej yog feem ntau desigtop digitalers.
Cov digital motions advanced siab cov duab tshuab, nrog cov qauv ntshiab thiab intuitive thiab kev nyeem ntawv raug. Nws tuaj yeem ua kom ntseeg tau lub hom phiaj ntawm kev nyeem thiab ua raws rau tib neeg txoj kev nyeem ntawv, uas tuaj yeem ua rau lub sijhawm nyeem ntawv luv lossis kaw sijhawm. Cov txiaj ntsig zoo no tsis muaj los ntawm kev analog (piv txwv li pointer) multimeters.
