Yuav kho tus pointer multimeter thaum nws hlawv (GVDA Digital multimeter)
Nyob zoo, Kuv zoo siab los teb koj cov lus nug. Qhov hluav taws xob thaiv kev puas tsuaj ntawm multimeter feem ntau yog tshwm sim los ntawm qhov tsis ncaj ncees lawm kev ntsuas ntawm qhov hluav taws xob nrog cov hluav taws xob thaiv. Cov khoom puas lawm feem ntau yog cov resistors ntawm cov khoom siv tiv thaiv. Koj tuaj yeem disassemble lub multimeter thiab saib nws. Feem ntau, koj yuav pom tias cov xim ntawm qhov tsis kam ntawm lub iav qhov twg qhov voltage tau ntsuas nrog cov iav tsis kam hloov. Tsuas yog hloov qhov tsis kam. . Yuav ua li cas kho lub multimeter Txoj kev kho ntawm lub pointer multimeter yog raws li nram no: 1: Yog hais tias lub multimeter puas los ntawm kev tsoo lub iav tsis ncaj ncees lawm, feem ntau koj tuaj yeem tshawb xyuas seb lub fuse hauv multimeter puas tau tawg. Yog tias nws tawg, tsuas yog hloov nws. Yog tias nws tsis tawg, nws yog qhov teeb meem hauv Circuit Court. Nws feem ntau yog kho zoo li no: thawj zaug qhib lub multimeter, muab lub iav rau lub iav thaum koj hlawv tawm, thiab tom qab ntawd xyuas seb qhov kev tiv thaiv ntawm lub iav puas puas. Yog tias nws puas lawm, tsuas yog hloov nws. [Vim cov resistors nyob rau hauv lub multimeter yog tag nrho cov tsis-tus qauv resistors, thiab lawv yog tag nrho cov high-precision resistors nrog 5- xim rings, nws yog ib qhov nyuaj rau yuav lawv. Koj tuaj yeem siv cov kev sib txuas thiab cov kev sib txuas kom tau txais qhov yuav tsum tau muaj tus nqi tiv thaiv], yog tias nws tsis zoo, nws feem ntau yog lub taub hau 'meter' raug puas tsuaj los ntawm overload.
