Kev tshem tawm txoj kev zais zais ntawm digital multimeter
Muaj ntau ntau hom digital multimeters, thiab lawv daim ntawv thov kuj dav heev. Txawm li cas los xij, tom qab tag nrho, multimeters yog ib qho ntawm cov khoom siv hluav taws xob, thiab tej zaum yuav muaj qee qhov teeb meem me me hauv kev siv. Nov yog qee cov lus qhia rau kev daws teeb meem.
1. Kev tsom xam Waveform.
Saib xyuas qhov voltage waveform, amplitude, lub sij hawm (frequency) ntawm txhua lub ntsiab lus tseem ceeb ntawm Circuit Court nrog ib qho hluav taws xob oscilloscope. Piv txwv li, yog lub moos oscillator pib vibrate los yog tsis, lub oscillation zaus yog 40kHz. Yog hais tias lub oscillator tsis muaj cov zis, nws txhais tau hais tias lub internal inverter ntawm TSC7106 puas, los yog lwm yam khoom yuav qhib. Saib xyuas tias lub waveform ntawm {21st} tus pin ntawm TSC7106 yuav tsum yog 50Hz square nthwv dej, txwv tsis pub, nws yuav yog kev puas tsuaj ntawm sab hauv 200 zaus faib.
2. Ntsuas qhov ntsuas qhov ntsuas.
Rau cov khoom nyob rau hauv qhov kev ua txhaum ntau, kev ntsuas hauv online lossis kev ntsuas offline yuav tsum tau ua, thiab qhov ntsuas qhov ntsuas yuav tsum raug txheeb xyuas. Thaum ntsuas qhov kev tawm tsam hauv online, qhov cuam tshuam ntawm cov khoom sib txuas hauv qhov sib npaug yuav tsum raug txiav txim siab.
3. Kev daws teeb meem zais.
Kev txhaum implicit hais txog qhov txhaum thaum qhov txhaum raug muab zais, thiab qhov ntsuas qhov zoo lossis qhov tsis zoo. Qhov kev ua txhaum no yog qhov nyuaj, thiab cov laj thawj feem ntau suav nrog kev sib txuas virtual ntawm cov pob qij txha, xoob ntawm cov khoom sib txuas, kev sib cuag tsis zoo ntawm kev hloov pauv hloov, kev ua haujlwm tsis ruaj khov ntawm cov khoom, thiab kev tawg txuas ntxiv ntawm cov hlau lead. Tsis tas li ntawd, nws kuj suav nrog qee yam sab nraud. Piv txwv li, ambient kub yog siab dhau lawm, cov av noo siab dhau lawm los yog muaj cov teeb liab muaj zog cuam tshuam nyob ze.
4. Kev tshuaj xyuas qhov tshwm sim.
Koj tuaj yeem kov seb qhov kub ntawm cov roj teeb, cov resistors, transistors thiab cov blocks sib xyaw yog siab dhau ntawm tes. Yog tias lub roj teeb uas tau nruab tshiab yog kub, lub voj voog yuav luv luv. Tsis tas li ntawd, koj yuav tsum tau soj ntsuam seb lub Circuit Court puas lawm, soldered, mechanically puas, thiab lwm yam.
5, kuaj xyuas qhov ua haujlwm voltage ntawm txhua qib.
Txhawm rau kuaj xyuas qhov ua haujlwm voltage ntawm txhua qhov taw tes thiab sib piv nrog tus nqi ib txwm muaj, qhov tseeb ntawm qhov siv hluav taws xob yuav tsum tau ua kom ntseeg tau ua ntej, thiab nws yog qhov zoo tshaj plaws los siv cov multimeter digital ntawm tib tus qauv lossis zoo sib xws los ntsuas thiab sib piv.
