Kev ntsuas txoj kev ohm thaiv ntawm digital multimeter
Lub hom phiaj tseem ceeb ntawm cov ntaub ntawv digital ohm yog ntsuas qhov tsis kam ntawm lub cev muaj zog winding, ntsuas seb cov hlau puas tawg, ntsuas qhov txuas ntxiv ntawm lub ntsaws, thiab lwm yam. Tus naj npawb 1 txhais tau hais tias: qhov ntsuas ntsuas tus nqi yog siab dua li tus nqi tiv thaiv los ntawm lub xov tooj ntawm lub tshuab multimeter (piv txwv li, thaum ntsuas 1K tsis kam, thiab koj tig lub xov tooj mus rau 200Ω, kev nyeem ntawv yuav pom 1) infinity ( kab rov tav 8 cim) yog tus nqi tiv thaiv ntawm lub insulator .
Kev ntsuas txoj kev ntawm digital multimeter ohm block
1. Xaiv qhov loj kom haum. Thaum ntsuas qhov tsis kam nrog lub ohmmeter, qhov kev nthuav dav tsim nyog yuav tsum raug xaiv kom tus pointer qhia ze rau tus nqi nruab nrab. Nws yog qhov zoo tshaj kom tsis txhob siv sab laug thib peb ntawm qhov ntsuas, uas tsis zoo scaled.
2. Kho rau xoom ua ntej siv.
3. Tsis txhob ntsuas nrog lub hwj chim rau.
4. Qhov kev tiv thaiv nyob rau hauv kev sim tsis tuaj yeem muaj ceg sib npaug.
5. Thaum ntsuas qhov sib npaug ntawm cov khoom siv polar xws li transistors thiab electrolysis, koj yuav tsum xyuam xim rau qhov polarity ntawm ob lub cwj mem.
6. Thaum ntsuas qhov sib npaug ntawm cov khoom tsis sib xws nrog lub ohm thaiv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, qhov ntsuas qhov ntsuas tsis sib txawv. Qhov no yog vim qhov nruab nrab tsis kam thiab qhov ntsuas tam sim no ntawm txhua lub iav sib txawv. Nyob rau hauv mechanical watches, qhov me dua qhov magnification, qhov me me ntawm qhov ntsuas tsis kam.
