Txoj kev txiav txim qhov zoo ntawm DC tam sim no cov ntaub ntawv (DCA) ntawm multimeter
Qhia koj paub txiav txim qhov zoo ntawm multimeter's DC tam sim no cov ntaub ntawv (DCA). Yog tias muaj qhov paub tam sim no, nkag ncaj qha rau hauv cov ntaub ntawv tam sim no. Yog tias tsis yog, koj tuaj yeem nkag siab qhov voltage hauv cov ntaub ntawv tam sim no. Tsis tas li ntawd, qee qhov kev ceev faj tau qhia rau koj siv.
Txoj kev txiav txim qhov zoo ntawm DC tam sim no cov ntaub ntawv (DCA) ntawm multimeter
Yog tias muaj qhov paub tam sim no, nkag ncaj qha rau hauv cov ntaub ntawv tam sim no. Yog tias tsis yog, tsuas yog nkag mus rau qhov hluav taws xob hauv lub iav tam sim no, yog tias nws yog 1, hu rau lub iav mus rau lub iav qis kom txog thaum tus nqi zoo tshwm.
Cov kev ceev faj:
1. Thov tsis txhob muab cov hluav taws xob ntau dhau, kom tsis txhob muaj qhov tam sim no ntau dhau thiab ua rau lub ntsuas hluav taws xob puas. Cov khoom siv uas tuaj yeem nkag tau yog cov roj teeb zoo tib yam, xws li No. 5, No. 7, thiab lwm yam;
2. Thaum ntsuas qhov tam sim no ntawm cov khoom siv hluav taws xob, vim tias qhov kev tiv thaiv (load) ntawm qhov kev tiv thaiv sab hauv ntawm lub 'meter' yog me me, yog tias cov tswv yim ntev dhau lawm, qhov chaw yuav raug puas tsuaj, yog li sim tsis txhob ntau tshaj 5 vib nas this. ib qho kev tawm tswv yim;
3. Txhua qhov siab thiab qis qis, qhov nyob ib sab, feem ntau yog 10 npaug ntawm kev sib raug zoo.
Cov saum toj no yog cov qauv siv los txiav txim qhov zoo ntawm DC tam sim no cov ntaub ntawv ntawm multimeter. Kev ua haujlwm yooj yim ib-kauj ruam tuaj yeem txiav txim siab seb DC tam sim no cov ntaub ntawv ntawm multimeter yooj yim siv.
