Tham txog cov kev daws teeb meem uas nquag siv ntawm cov digital puv
Cov teeb meem daws teeb meem ntawm cov motsisters digital feem ntau pib nrog lub zog hluav taws xob. Piv txwv li, tom qab txuas cov hluav taws xob muab, yog tias LCD cell tshwm sim, thawj qhov kev tshawb xyuas yog seb tus hluav taws xob ntawm 9V stacked roj teeb yog tsawg dhau; Yog lub roj teeb ua disrged. Kev tshawb nrhiav cov teeb meem yuav tsum ua raws li kev txiav txim ntawm "hauv 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.
Yog qhov ntsuas kub nce ntawm lub roj teeb, resistor, transistor, thiab kev sib xyaw uas tuaj yeem kov tau los ntawm txhais tes 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. Ib qho ntxiv, nws yog ib qho tsim nyog los tshawb xyuas seb qhov Circuit Court tau tawg, desoldered, mechanically puas, thiab lwm yam.
2, khij qhov hluav taws xob ntawm txhua theem ntawm kev ua haujlwm.
Txheeb xyuas cov kev ua haujlwm hluav taws xob ntawm txhua qhov taw tes thiab sib piv nws nrog tus nqi ib txwm muaj. Firstly, xyuas kom qhov tseeb ntawm cov hluav taws xob siv hluav taws xob, nyiam dua siv cov digital pultimeter ntawm tib hom lossis ib qho sib txawv rau kev ntsuas thiab kev sib piv.
3, Kev Ntsuam Xyuas WetForm.
Siv cov hluav taws xob oscilloscope kom tshawb xyuas cov voltage wavefore, hloov pauv, lub sijhawm (zaus), thiab lwm yam ntawm txhua qhov tseem ceeb hauv Circuit Court. Piv txwv li, yog tias lub moos vibrator tabtom pib tshee thiab qhov ntau zaus yog 40kHz. Yog hais tias lub vibrator tsis muaj kev tsim tawm, 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 cov khoom tsis sib xws.
Rau cov khoom siv nyob rau hauv cov teeb meem ntawm cov teeb meem, online lossis cov kev ntsuas offline yuav tsum tau coj, thiab ntsuas qhov tseem ceeb yuav tsum raug tshuaj xyuas. Thaum ntsuas kev tiv thaiv online, cov cawv ntawm kev sib txuas ntawm cov Cheebtsam sib txuas yuav tsum tau txiav txim siab.
5, Tshem tawm cov teeb meem zais zais.
Cov mob uas zais rau qhov xwm txheej uas cov teeb meem tshwm sim thiab ploj, thiab qee zaum yog qee zaum zoo thiab qee zaum tsis zoo. Cov teeb meem no yog cov txheej txheem sib txawv, nrog cov khoom sib koom ua ke, cov kev sib txuas tsis ruaj khov, thiab cov khoom sib txawv ntawm cov thawj coj. Tsis tas li ntawd, nws tseem suav nrog qee yam sab nraud uas tsim. Xws li cov huab cua siab huab cua, siab vaum, lossis sib quas ntus muaj zog cuam tshuam cov teeb tsa kev cuam tshuam ntawm cov phiajcim hauv ib puag ncig.
