Tsib lub peev txheej daws teeb meem rau cov kev sib sau digital
Cov digital motimeter (DMM) yog qhov ntsuas ntsuas uas siv cov qauv hloov pauv hloov mus rau cov kev ntsuas ntsuas rau hauv cov ntawv ntsuas digital. Piv nrog pointer multimeters, cov multiver tau dav lawm, kev nyeem ntawv tshiab, muaj zog anti {}}} sib cuam tshuam, thiab muaj peev xwm
Qib ntsuas kev ntsuas tshuab ntsuas. Tab sis yog tias siv tsis raug, nws tuaj yeem ua rau ua tsis tau zoo.
Kab lus no yuav siv digital puv ntuas piv txwv piv txwv los tham txog cov kev daws teeb meem dav dav rau cov qauv kev sib cuam tshuam rau digital.
Kev daws teeb meem Cov digital puv feem ntau pib nrog lub zog hluav taws xob. Piv txwv li, tom qab txuas cov hluav taws xob muab, yog tias lub roj teeb ntawm 9V stacked yuav tsum tau kuaj ua ntej kom pom tias nws qis dhau; Yog lub roj teeb ua disrged. Kev tshawb nrhiav rau kev ua txhaum yuav tsum ua raws li kev txiav txim ntawm "sab hauv ua ntej, ces sab nraud, yooj yim ua ntej, ces nyuaj". Cov teeb meem daws teeb meem ntawm cov digital motimeter tuaj yeem yog kwv yees raws li hauv qab no.
1, kev tshuaj xyuas zoo nkauj.
Koj tuaj yeem kov cov roj teeb, tiv taus, transistor, thiab sib xyaw nrog koj txhais tes los kuaj seb nws puas siab dhau. Yog tias cov roj teeb uas tau teeb tsa tshiab dua, nws qhia tau tias lub Circuit Court kuj yuav yog luv dua ci ntsa iab. Tsis tas li ntawd, nws yog ib qho tsim nyog los saib seb lub Circuit Court yog tawg, demoldered, mechanically puas, thiab lwm yam.
2, Txheeb xyuas qhov kev ua haujlwm hluav taws xob ntawm txhua qib.
Txhawm rau txhawm rau ua haujlwm voltage ntawm txhua qhov taw tes thiab sib piv nws nrog tus nqi ib txwm muaj, qhov tseeb ntawm cov ntaub ntawv voltage yuav tsum ua ntej. Nws yog qhov zoo tshaj plaws los siv cov digital mottimeter ntawm tib yam lossis zoo sib xws rau kev ntsuas thiab kev sib piv.
3, Kev Ntsuam Xyuas WetForm.
Saib lub voltage waveforms, amplitude, sijhawm (zaus (zaus), thiab lwm yam ntawm txhua qhov tseem ceeb hauv kev siv hluav taws xob oscilloscope. Piv txwv li, txhawm rau ntsuas seb lub moos oscillator pib oscillating thiab seb puas zaus tshuaj esScillation yog 40kHz. Yog tias tus oscillator tsis muaj qhov zis, nws qhia tau tias TSC7106 sab hauv inverter raug puas tsuaj, lossis nws yuav yog qhov qhib Circuit Court hauv sab nraud. Cov nthwv dej uas pom ntawm Pin {21} ntawm TSC7106 yuav tsum yog 50Hz square yoj, txwv tsis pub nws yuav yog vim kev puas tsuaj rau sab hauv 200 zaus divider.
4, ntsuas cov khoom tsis sib xws.
Rau cov khoom siv hauv cov khoom txhaum cai, online lossis kev ntsuas offline yuav tsum tau ua, thiab ntsuas qhov tseem ceeb yuav tsum tau tshuaj xyuas. Thaum ntsuas kev tiv thaiv online, muaj feem xyuam ntawm cov khoom sib txuas hauv cov parallel yuav tsum tau txiav txim siab.
5, zais kev daws teeb meem.
Muab zais cov kev ua txhaum cai uas tshwm sim thiab ploj cov sib npaug, nrog lub twj paj nruag sib txuas hloov ntawm qhov zoo thiab tsis zoo. Qhov kev txhaum no yog qhov nyuaj heev, thiab cov ua ke sib txawv, xoob txuas, tsis ruaj khov ntawm cov khoom lag luam, thiab tawg tom qab ua haujlwm. Tsis tas li ntawd, nws tseem suav nrog cov xwm txheej tshwm sim los ntawm cov sab nraud yam. Xws li cov huab cua siab huab cua, siab vaum, lossis sib quas ntus muaj zog cuam tshuam cov phiajcim ntawm cov phiajcim uas nyob ze.
