Multimeter ntes cov xov hlau luv luv
1. Kev txheeb xyuas txoj kev
Cais cov cores ntawm ob qhov kawg ntawm cov hlau, ceev faj tsis txhob hla los yog kov ib leeg, ces ntaus lub multimeter mus rau txoj hauj lwm saum toj no (daim duab 1), thiab muab cov cwj mem xeem rau ntawm ob qhov sib txawv xim xaim. Short-circuit ntsuas kev ua haujlwm.
Lub multimeter kuaj pom qhov luv luv ntawm cov xaim thiab muab qhov tshwm sim hauv vib nas this yam tsis muaj kev siv zog
2. Cov ntawv xeem
Kev ntsuas ntawm 0 qhia tias luv luv ntawm ob lub xov hlau. Yog tias qhov ntsuas ntsuas pom tau tias tsis muaj qhov kawg, nws txhais tau tias tsis muaj teeb meem nrog kab.
3. Cov teeb meem xav tau kev saib xyuas
Thaum ntsuas qhov luv luv ntawm Circuit Court, thawj zaug tua lub qhov rooj tseem ceeb ntawm cov khoom siv hluav taws xob, tom qab ntawd kho qhov hloov ntawm multimeter mus rau 1 lossis 10 ohms, thiab ntsuas ob lub xaim kawg ntawm tib pab pawg ntawm circuits. . Yog tias qhov tsis kam yuav luag 0, nws txhais tau tias luv luv Circuit Court.
Txoj kev ntsuas yooj yim:
Siv lub ohm x1 iav ntawm multimeter los ntsuas ob kawg ntawm kab. Yog hais tias tus nqi kuj nyob ze rau xoom, nws yog luv luv Circuit Court. Thaum muaj qee qhov kev tiv thaiv tus nqi (nyob ntawm qhov thauj khoom hauv kab), nws tsis tuaj yeem txiav txim siab seb nws puas yog luv luv lossis tsis yog. Thaum qhov hluav taws xob tsis tu ncua, tus nqi tiv thaiv Qhov me me, qhov loj dua qhov tam sim no ntws los ntawm txoj kab.
Siv lub ohm 1k lossis 10k iav ntawm multimeter los ntsuas ob qhov kawg ntawm kab. Yog hais tias tus nqi kuj yog infinite, nws txhais tau hais tias ib tug qhib Circuit Court.
