Yuav ua li cas yog tias qhov tsis kam ntawm ib qho digital multimeter tsis mus rau 0 thaum luv?
Tuav lub HOLD + RANGE cov yuam sij ib txhij rau 10 vib nas this rau xoom.
Cov multimeters digital muaj nyob rau hauv cov khoom siv nqa tau yooj yim rau kev daws teeb meem yooj yim lossis raws li lub rooj zaum hauv tsev, 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.
Txawm li cas los xij ntawm cov lus digital, 20MΩ lossis 200MΩ thaiv, uas yog, ntau tshaj 20MΩ iav tiv thaiv thaiv txawm tias muaj kev tiv thaiv siab, siab tiv thaiv luv luv tus cwj mem qhia 0.9 feem ntau yog ib txwm, Nyob rau hauv rooj plaub ntawm kev txiav txim siab 7106 siv voltage yog qhov qub, luv luv tus cwj mem 0.9 tsis suav tias yog qhov txhaum. Vim tias 200MΩ belongs rau lub siab tiv thaiv thaiv.
Digital multimeter kuj ntsuas cov kauj ruam
Kauj ruam 1: Ntxig tus cwj mem dub rau hauv "COM" qhov, tus cwj mem liab rau hauv "VΩ" qhov.
Kauj Ruam 2: Xaiv cov kev tiv thaiv uas tsim nyog, cov cwj mem dub thiab xim liab tau txuas nrog ob qho kawg ntawm cov resistor, ua tib zoo mloog kom tsis txhob siv koj txhais tes tib lub sijhawm los tiv tauj ob qhov kawg ntawm cov resistor, vim tib neeg lub cev. yog ib tug loj heev resistive conductor, uas muaj feem xyuam rau qhov tseeb ntawm kev ntsuas tsis kam.
Kauj Ruam 3: Muab cov ntaub ntawv qhia ntawm cov zaub nrog cov kev tiv thaiv kom tau txais qhov ntsuas qhov kawg.
