Cov lus piav qhia txog tsib txoj hauv kev rau kev daws teeb meem digital multivers
Ib qho digital pululation yog qhov ntsuas ntsuas uas siv txoj ntsiab cai ntawm kev ntsuas ntsuas rau cov ntaub ntawv ntsuas rau hauv cov ntawv ntsuas digital. Piv nrog pointer multimeters, digital multiv yog qhov tseeb, kev nyeem ntawv digital, muaj zog tshaj tawm, thiab kev ntsuas tsheb siab. Tab sis yog tias siv tsis raug, nws tuaj yeem ua rau ua tsis tau zoo.
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, Pom kev tshuaj xyuas: koj tuaj yeem kov lub roj teeb, resistor, thiab kev sib xyaw nrog koj txhais tes kuaj yog qhov ntsuas kub 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, kuaj cov haujlwm hluav taws xob ntawm txhua theem: kuaj pom qhov chaw ua haujlwm ntawm txhua kis thiab sib piv nws nrog tus nqi ib txwm muaj. Firstly, qhov tseeb ntawm kev siv hluav taws xob yuav tsum muaj kom ntseeg tau. Nws yog qhov zoo tshaj plaws los siv cov digital puv ntawm tib cov qauv lossis cov qauv zoo sib xws rau kev ntsuas thiab kev sib piv.
3, Kev Ntsuam Xyuas WaveForm: Siv hluav taws xob hluav taws xob oscilloscope saib lub voltage waveforcope mus saib lub zog hluav taws xob, lub sijhawm (zaus), thiab lwm yam. 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 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 kev sib xyaw ua ke: rau cov khoom siv hauv cov khoom txhaum cai, online lossis cov 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, Muab kev ua txhaum kev ua txhaum cai: zais zais kev ua yuam kev uas tshwm sim thiab ploj mus sib tshuam, thiab lub cuab yeej ntsuas muaj qee zaum zoo lossis tsis yog. Qhov kev txhaum no yog qhov nyuaj heev, thiab cov ua ke muaj suav nrog cov pob qij txha sib txawv, kev sib cuag ntawm cov khoom siv hloov chaw, thiab cov khoom noj khoom haus tsis ruaj khov. 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.
