Cov txheej txheem txheej txheem rau kev daws teeb meem nrog digital multimeters
1, Kev tshuaj xyuas qhov tshwm sim.
Koj tuaj yeem kov qhov kub thiab txias ntawm lub roj teeb, resistor, transistor, thiab kev thaiv nrog koj txhais tes los xyuas seb nws siab dhau lawm. Yog tias lub roj teeb uas tau nruab tshiab sov, nws qhia tau hais tias lub voj voog yuav luv luv. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam seb lub Circuit Court puas tawg, desoldered, mechanically puas, thiab lwm yam.
2, Tshawb xyuas qhov ua haujlwm voltage ntawm txhua qib.
Txhawm rau txheeb 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 ua kom ntseeg tau ua ntej. Nws yog qhov zoo tshaj plaws los siv ib qho digital multimeter ntawm tib lossis zoo sib xws rau kev ntsuas thiab kev sib piv.
3, Kev tsom xam Waveform.
Saib xyuas qhov voltage waveform, amplitude, lub sij hawm (frequency), thiab lwm yam ntawm txhua qhov tseem ceeb hauv Circuit Court siv lub tshuab hluav taws xob oscilloscope. Piv txwv li, txhawm rau kuaj seb lub moos oscillator pib oscillating thiab seb qhov oscillation zaus yog 40kHz. Yog tias lub oscillator tsis muaj qhov tso tawm, nws qhia tau tias TSC7106 sab hauv inverter puas lawm, lossis nws yuav yog qhov qhib Circuit Court hauv cov khoom sab nraud. Lub waveform pom ntawm tus pin {21} ntawm TSC7106 yuav tsum yog 50Hz square nthwv dej, txwv tsis pub nws yuav yog vim kev puas tsuaj rau sab hauv 200 zaus faib.
4, Ntsuas qhov ntsuas qhov ntsuas.
Rau cov khoom nyob rau hauv qhov txhaum ntau, kev ntsuas hauv online lossis offline yuav tsum tau ua, thiab qhov ntsuas qhov ntsuas yuav tsum tau txheeb xyuas. Thaum ntsuas kev tiv thaiv hauv online, qhov cuam tshuam ntawm cov khoom sib txuas hauv qhov sib npaug yuav tsum raug txiav txim siab.
5, Kev daws teeb meem zais zais.
Nkaum faults hais txog qhov txhaum uas tshwm sim thiab ploj mus tsis tu ncua, nrog lub ntsuas vaj huam sib luag hloov pauv ntawm qhov zoo thiab qhov tsis zoo. Hom kev ua haujlwm tsis zoo no yog qhov nyuaj heev, nrog rau cov laj thawj xws li virtual soldering ntawm cov pob qij txha, loosening, xoob connectors, kev nyab xeeb ntawm kev hloov pauv hloov, kev ua haujlwm tsis ruaj khov, thiab kev ua haujlwm tsis tu ncua. Tsis tas li ntawd, nws kuj suav nrog cov xwm txheej tshwm sim los ntawm lwm yam. Xws li ambient kub, high humidity, los yog intermittent muaj zog cuam tshuam teeb liab nyob ze.
