Kev daws teeb meem zais zais hauv cov lej digital
Lo lus multimeter muaj ntau cov kev siv ntawm cov ntawv thov tseem dav, tab sis tom qab tag nrho cov teeb meem me me, ntawm no los qhia ob peb cov ntsiab lus ntawm cov hau kev me me.
1, kev soj ntsuam nthwv dej.
Nrog rau hluav taws xob oscilloscope kom saib cov Circuit Court ntawm txhua tus tseem ceeb ntawm cov hluav taws xob ntub, amplitude, zaus (zaus) thiab lwm yam. Piv txwv li, xws li ntsuas seb puas cai moos oscillator kev co, qhov ntau oscillation zaus yog 40 kHz. Yog tias tus oscillator tsis muaj qhov zis, lub TSC7106 sab hauv inverter raug puas ntsoog, kuj tseem yog ib qho kev tiv thaiv sab nraud qhib Circuit Court. Soj ntsuam TSC7106 ko taw {21} WaveForm yuav tsum yog 50hz square yoj, txwv tsis pub, nws yuav yog qhov kev puas tsuaj sab hauv.
2, ntsuas cov tshuaj sib txuas.
Rau cov khoom siv hauv cov qauv ntawm qhov ua txhaum, kev ntsuas online lossis kev ntsuas offline lossis kev ntsuas offline, ntsuas qhov tseem ceeb yuav tsum tau tshuaj xyuas. Rau kev tiv thaiv online, yuav tsum xav txog qhov cuam tshuam ntawm cov tib yam txuas nrog rau nws.
3, zais kev daws teeb meem.
Muab kev txhaum hais txog qhov txhaum yog muab zais, qhov ntsuas yog qhov ua tau zoo lossis ua phem. Xws li kev ua tsis tiav yog qhov nyuaj ntxiv, cov pob qij txha sib txawv, xoob nrog kev hloov tsheb hloov, cov hmoov txhuas tsis ruaj khov, cov hmoov txhuas tsis ruaj khov, cov hmoov txhuas yuav tawg thiab lwm yam. Tsis tas li ntawd, tseem suav qee cov ntsiab lus sab nraud los ntawm. Xws li cov huab cua siab ambient kub, ntau dhau noo lossis sib txawv muaj zog cuam tshuam cov phiajcim ntawm cov phiajcim uas nyob ze thiab lwm yam.
4, pom kev kos duab.
Koj tuaj yeem kov lub roj teeb, resistor, transistor, sib koom ua ke ntsuas kub nce siab dhau lawm. Yog tias lub roj teeb lo tshiab yog kub, qhia tias qhov Circuit Court kuj yuav luv-taws. Ib qho ntxiv, yuav tsum tau saib ntsoov seb lub Circuit Court yog tawg, desoldering, tshuab puas tsuaj.
5, sim cov haujlwm ua haujlwm ntawm txhua qib.
Tshawb nrhiav cov kev ua haujlwm dav dav ntawm ntau cov ntsiab lus, thiab piv nrog tus nqi ib txwm muaj, nws yog qhov zoo tshaj plaws, nws yog qhov zoo tshaj plaws los siv ib qho qauv ntawm tib cov qauv lossis cov digital zoo sib xws rau kev ntsuas thiab kev sib piv.
