Multimeter siv - automotive voltage ntsuas
1. Lub pob qhov rooj yuav tsum tau teem rau V thaum ntsuas qhov hluav taws xob DC ntawm lub tsheb, thiab lwm qhov kev taw qhia yuav tsum tau siv thaum ntsuas qhov hluav taws xob AC, thiab qhov sib npaug ntawm qhov ntsuas hluav taws xob ntawm lub tsheb yuav tsum tau xaiv. Yog tias qhov ntsuas tsis paub qhov voltage, qhov siab tshaj plaws yuav tsum raug xaiv rau qhov ntsuas.
2. Thaum ntsuas DC voltage nyob rau hauv ib lub tsheb, qhov kev ntsuam xyuas zoo ntawm cov multimeter yuav tsum tau txuas nrog lub siab muaj peev xwm kawg ntawm cov khoom nyob rau hauv kev ntsuam xyuas, thiab qhov kev ntsuam xyuas tsis zoo ua rau qhov tsis muaj peev xwm kawg. Yog tias koj tsis tuaj yeem txiav txim siab qhov kawg twg muaj peev xwm tshaj plaws, koj tuaj yeem kov qhov kev sim ua rau ob qhov kawg ntawm cov khoom siv kuaj. Yog hais tias tus taw tes yog biased rau "-" sab ntawm xoom kab ntawm DC voltage V, nws ua pov thawj tias cov kev xeem coj rov qab.
Nws yog ib qho yooj yim rau khoov tus pointer thaum tus cwj mem xeem rov qab, ua rau kev nyeem tsis raug. Txhawm rau tiv thaiv kev thim rov qab, qhov ntau yuav tsum tau xaiv ntau dua thaum sim kov, thiab qhov kev txiav txim yuav tsum ceev.
