Digital multimeter resistor tsis rov pib dua rau xoom
Digital Multimeter Resistance Tsis Zeroing
Qhov no yog qhov teeb meem calibration nrog lub multimeter.
Nws yog ib qho uas cov multimeters tsis rov qab mus rau xoom.
Nws muaj tsawg heev ua rau kub, av noo thiab ib puag ncig.
Yog tias nws nyob hauv 5 dhia, nws feem ntau suav hais tias tsim nyog.
Piv txwv li, Festech FT368 multimeter, tsib kaum-phav ntawm ib nti raug.
Qhov tsis kam ntawm qhov luv-circuit ntawm lub meter koob ntawm -0.02 ~ 0.02 ohm yog tsim nyog.
Qhov koj hais saum toj no tej zaum yuav muaj teeb meem calibration thaum lub 'meter' raug xa los ntawm lub Hoobkas.
Yuav ua li cas ua kom tsis kam ntawm digital multimeter tsis 0 thaum luv?
Tuav tus yuam sij HOLD+RANGE rau 10 vib nas this tib lub sijhawm kom tau mus rau 0.
Cov multimeters digital muaj nyob rau hauv cov khoom siv nqa tau yooj yim rau kev daws teeb meem, lossis raws li lub rooj ntev zaum tso, qee qhov kev daws teeb meem txog li xya lossis yim tus lej.
Digital multimeter yog ib qho khoom siv hluav taws xob siv los ntsuas hluav taws xob. Nws tuaj yeem muaj ntau yam haujlwm tshwj xeeb, tab sis lub luag haujlwm tseem ceeb yog ntsuas qhov voltage, tsis kam thiab tam sim no. Digital multi-meters, raws li niaj hnub multi-purpose electronic ntsuas ntsuas, feem ntau yog siv nyob rau hauv lub cev, hluav taws xob thiab hluav taws xob ntsuas.
Digital multi-meter hais txog kev nyab xeeb nta
1, Fuse tam sim no input tiv thaiv.
2, Siv lub zog siab fuse tawm (600 volts lossis siab dua).
3, Kev tiv thaiv hluav taws xob siab hauv hom tsis kam (500 volts lossis siab dua).
4, Kev tiv thaiv voltage (6000 volts lossis siab dua).
5, Kev nyab xeeb tsim kev xeem coj, kev nyab xeeb tuav, thiab lwm yam.
6, Independent kev ruaj ntseg ntawv pov thawj.
