Tsib Txoj Kev daws teeb meem rau Digital Multimeters
1. Kev tshuaj xyuas qhov muag thiab lub cev
Kov cov khoom xws li roj teeb, resistors, transistors thiab integrated-circuit chips los ntawm tes los xyuas seb qhov kub thiab txias ntau dhau. Yog hais tias lub roj teeb uas tau nruab tshiab kub, qhov luv-circuit yuav muaj nyob rau hauv Circuit Court. Tsis tas li ntawd, tshawb xyuas lub voj voog rau cov xov hlau tawg, cov pob qij txha txias thiab cov neeg kho tshuab puas.
2. Kev ntsuas kev khiav hauj lwm voltage ntawm txhua theem
Ntsuas qhov kev khiav hauj lwm qhov hluav taws xob ntawm txhua qhov ntsuas thiab sib piv cov ntawv nyeem tawm tsam cov nqi siv ib txwm muaj. Ua ntej xyuas qhov tseeb ntawm qhov siv voltage. Nws raug nquahu kom ua qhov ntsuas thiab sib piv siv lwm qhov digital multimeter ntawm tib lossis zoo sib xws
3. Kev tsom xam Waveform
Siv ib qho oscilloscope los soj ntsuam qhov voltage waveform, amplitude, lub sij hawm (frequency) thiab lwm yam tsis muaj nyob rau ntawm qhov tseem ceeb Circuit Court nodes. Piv txwv li, xyuas seb lub moos oscillator pib oscillation thiab seb nws cov zaus oscillation mus txog 40 kHz. Yog hais tias lub oscillator tsis tsim tawm, lub internal inverter nyob rau hauv lub TSC7106 tej zaum yuav puas, los yog lwm yam khoom yuav qhib-circuited. Lub waveform ntawm tus pin 21 ntawm TSC7106 yuav tsum yog 50 Hz square-wave; txwv tsis pub, qhov sib faib sab hauv-by-200 zaus sib faib yuav ua yuam kev.
4. Kev ntsuas ntawm cov khoom tsis sib xws
Ua cov kev ntsuas hauv-circuit lossis off-circuit rau cov khoom nyob rau hauv faulty seem thiab txheeb xyuas lawv cov nqi parameter. Thaum ntsuas cov resistors nyob rau hauv-circuit, coj mus rau hauv tus account qhov cuam tshuam los ntawm cov khoom sib txuas ua ke.
