Cov khoom siv hluav taws xob yog cov cuab yeej tseem ceeb rau txhua tus neeg koom nrog hauv cov khoom siv hluav taws xob. Nws tshwm sim rau kuv kom muaj Korad, uas yog kab tawm (hnyav) lub zog muab khoom uas yog tus nqi zoo thiab tau txais kev tshuaj xyuas zoo.
Dab tsi yog lub hwj chim thiab dab tsi yog qhov teeb meem qhov kev qhia qhia daws qhov no
Lub luag haujlwm tseem ceeb ntawm lub zog siv hluav taws xob yog txhawm rau txhawm rau thauj khoom nrog teeb tsa qhov teeb meem tas mus li lossis qhov tam sim no. Txawm li cas los xij yog tias cov xov tooj uas peb siv tau ntev lossis tsis zoo, thiab tam sim no ntawm peb lub Circuit Court yog qhov txiav txim siab, ces yuav muaj qhov tseem ceeb (nyob ntawm daim ntawv thov) qhov hluav taws xob poob thoob plaws cov xov hlau. Qhov ntawd yuav ua rau qis qis dua li tau teev tseg thoob plaws lub nra. Ib qho kev daws teeb meem, yog siv cov xov hluav taws xob luv nrog qhov ua haujlwm me me (qhov ua tau zoo), tab sis qhov ntawd ib txwm tsis ua tiav.
Ntau yam khoom siv hluav taws xob, kim dua li korad, txhawm rau tshem tawm qhov teeb meem no muaj peev xwm ua rau pom kev deb.
Kev ua haujlwm nyob deb li cas
Kuv tsis tuaj yeem piav qhia qhov chaw hnov zoo dua tias tinbin ntawm no:
community.keysight.com/community/keysight-…
Kuv pom zoo tsab xov xwm no, yog li rau koj cov uas nyem qhov txuas no lossis paub txog qhov teeb meem koj tuaj yeem hla ob nqe lus hauv qab no.
Los ntawm cov khoom siv hluav taws xob tsis zoo nkag siab qhov hluav taws xob hla qhov ntsuas qhov ntsuas ntawm psu. Piv txwv li yog tias peb tau teeb tsa qhov hluav taws xob tso tawm kom yog 5V thiab vim li cas los xij psu nkag siab hauv zos 4.8 volts ntawm nws cov zis, tom qab ntawd yuav nce qhov hluav taws xob kom txog thaum nws hnov dua 5V. Txawm li cas los xij yog tias muaj qhov hluav taws xob poob ntawm 0.2 volts hla cov xov hlau, yog li hauv qhov kev thauj khoom "pom" tsuas yog 4.8 volts, psu yuav tsis nce qhov hluav taws xob ntawm nws cov zis vim nws tseem hnov 5V hauv zos ua ntej cov xov hlau khiav.
Vim li ntawd cov qauv kawg siab dua tuaj yeem muaj peev xwm paub qhov deb. Ntawd yog lawv muaj qhov chaw nres nkoj tso tawm ntxiv uas peb tuaj yeem ntsaws ib khub ntawm cov xov hlau rau kev hnov qhov chaw deb. Lwm qhov kawg ntawm kev hnov xov hlau txuas rau lub nra. Yog li yog vim li cas los xij (suav nrog poob ntawm cov xov hlau) qhov hluav taws xob hla qhov thauj khoom tsawg dua qhov tau teev tseg, psu yuav nkag siab nws (thaum thauj khoom lub sijhawm no) thiab nce qhov hluav taws xob ntawm nws qhov tso tawm kom txog rau thaum qhov ntsuas hluav taws xob rov ua dua qhov tshwj xeeb. Piv txwv li yog tias peb pom 5V qhov hluav taws xob tso tawm thiab qhov hluav taws xob poob hla cov xov hlau yog 0.2V tom qab ntawv lub zog hluav taws xob yuav nyob deb ntawm 4.8 volts ntawm kev thauj khoom yog li yuav nce qhov tso tawm hluav taws xob kom txog thaum qhov hluav taws xob rov ua dua 5V. Kuv rov hais dua kuv tus kheej Kuv paub!
