Vim li cas qhov tseeb RMS tseem ceeb heev rau clamp meters?
Thaum xaiv lub ntsuas ntsuas clamp, cov lus nug feem ntau yog "yuav ua li cas" thiab "qhov tseeb". Muaj ntau yam cuam tshuam rau qhov tseeb ntawm lub ntsuas ntsuas clamp, xws li kev tsim / kev ua haujlwm, kev siv bandwidth, zaus teb, suav nrog seb puas yog xaiv ntau yam, txhua yam yuav cuam tshuam rau kev nyeem ntawv. Txawm li cas los xij, ntawm tag nrho cov xwm txheej no, ib qho tseem ceeb tshaj plaws yog qhov tseeb RMS ntsuas, tshwj xeeb tshaj yog rau cov neeg siv khoom lag luam nrog ntau yam khoom siv hluav taws xob thiab cov khoom siv hluav taws xob nyuaj.
Tus nqi tsis muaj tseeb, uas yog, qhov ntsuas nruab nrab teb, feem ntau yog rau kev ntsuas ntawm sine yoj ntawm tus qauv fais fab zaus. Ib txoj hauv kev siv feem ntau yog los hloov cov ntsuas ntsuas ntsuas ntsuas qhov ntsuas x1.1 rau hauv sine yoj 'tus nqi zoo' kev nyeem ntawv. Qhov no tsis muaj teeb meem nyob rau hauv ib puag ncig uas ib puag ncig hluav taws xob yog qhov yooj yim, xws li cov tsev thiab cov khoom.
Nyob rau hauv ib puag ncig kev lag luam dav, tshwj xeeb tshaj yog siv ntau thiab ntau cov cuab yeej xws li kev hloov pauv zaus, rectifiers, thiab inverters, qhov tseeb waveforms tau dhau los ua ntau thiab ntau haiv neeg, thiab ntau thiab ntau lub suab nrov nrov tau qhia, yog li nws yog qhov tsim nyog. kom raug ntsuas, qhov tseeb muaj txiaj ntsig zoo dhau los ua ib qho tseem ceeb tshaj plaws.
Thaum nws los txog rau lub suab nrov lossis kev sib haum xeeb, lwm lub tswv yim tseem ceeb yuav tsum tau hais txog: low-pass filter (LPF). Qhov cuam tshuam yog tias tsuas yog qhov tsawg zaus tam sim no thiab qhov hluav taws xob tuaj yeem ntsuas tau, thiab qhov siab zaus yuav raug txiav tawm thiab tsis suav. Nws tuaj yeem hais tau tias tsuas yog qhov tseeb tus nqi clamp meter nrog qis-pass filtering yog qhov muaj txiaj ntsig tiag tiag 'tus nqi zoo tiag tiag'
