Yuav ua li cas txiav txim seb qhov DC voltage ntawm multimeter yog qhov qub?
Txhawm rau txiav txim siab seb DCV ntau yam ntawm multimeter yog qhov qub, hloov lub multimeter mus rau qhov yuav tsum tau muaj DC voltage ntau thaum kuaj, ntxig qhov kev xeem ua raws li cov lus qhia, txuas qhov chaw tshawb nrhiav, thiab nyeem cov ntawv nyeem ntawm LCD.
Tus txheej txheem ntawm kev txiav txim seb lub DC voltage iav DCV ntawm lub multimeter yog qhov qub
DC voltage ntau ntawm multimeter yog DCV
Thaum kuaj, koj yuav tsum xub nrhiav qhov chaw sim. Vim tias nws yog qhov zoo thiab qhov ntsuas qhov ntau, muaj ntau qhov kev ntsuam xyuas muaj. Cov chaw kuaj hauv tsev muaj xws li 1.5V alkaline / carbon roj teeb (No. 1, No. 5 / AA, No. 7 / AAA), 1.2V rechargeable roj teeb, xov tooj ntawm tes charger, fais fab adapter, thiab lwm yam.
Thaum kuaj, tig lub multimeter mus rau qhov yuav tsum tau DC voltage theem, ntxig rau qhov kev xeem ua raws li cov lus qhia, txuas lub xeem qhov chaw, thiab nyeem cov ntawv nyeem ntawm lub LCD, tsuav yog tus nqi ntsuas nyob ib ncig ntawm lub nominal voltage. .
Nco ntsoov, rov hais dua, nws yog qhov zoo ntxiv rau qhov ntsuas me ntsis, yog li cov peev txheej no tuaj yeem siv tau, vim tias qhov hluav taws xob ntawm cov peev txheej no tsis ruaj khov, zoo li 1.5V roj teeb, lub roj teeb tshiab tuaj yeem ncav cuag ntau dua 1.6V, thiab cov cov roj teeb qub yuav tsuas muaj xoom point ob peb volts.
