Kev daws teeb meem ntawm zais qhov yuam kev hauv digital multimeters
Muaj ntau ntau hom digital multimeter, Scope ntawm daim ntawv thov kuj dav heev, tab sis tom qab tag nrho, lub multimeter belongs rau ib yam ntawm cov khoom siv hluav taws xob, tej zaum nyob rau hauv tus txheej txheem ntawm kev siv ib co teeb meem me me, ntawm no qhia ob peb lub ntsiab lus ntawm kev daws teeb meem me me. txoj kev.
1, waveform tsom xam.
Nrog lub tshuab hluav taws xob oscilloscope los saib xyuas lub voj voog ntawm txhua lub ntsiab lus tseem ceeb ntawm qhov hluav taws xob waveform, amplitude, lub sij hawm ( zaus) thiab lwm yam. Piv txwv li, xws li ntsuas seb lub moos oscillator vibration, oscillation zaus yog 40 kHz. Yog hais tias lub oscillator tsis muaj qhov tso zis, TSC7106 sab hauv inverter puas lawm, kuj yuav yog ib qho khoom siv sab nraud qhib Circuit Court. Saib TSC7106 ko taw {21} waveform yuav tsum yog 50Hz square nthwv dej, txwv tsis pub, nws yuav yog 200 zaus faib kev puas tsuaj.
2, ntsuas qhov ntsuas qhov ntsuas.
Rau cov khoom nyob rau hauv qhov kev ua txhaum, kev ntsuas hauv online lossis kev ntsuas offline, qhov ntsuas qhov ntsuas yuav tsum raug tshuaj xyuas. Rau kev ntsuas kev tiv thaiv online, yuav tsum xav txog qhov cuam tshuam ntawm cov khoom sib txuas nrog nws.
3, kev daws teeb meem zais.
Hidden fault hais txog qhov txhaum yog muab zais, qhov ntsuas yog qee zaum zoo thiab qee zaum ua txhaum. Xws li kev ua tsis tiav yog qhov nyuaj dua, feem ntau ua rau muaj kev sib koom ua ke ntawm cov pob qij txha, xoob, xoob txuas, kev sib cuag tsis zoo nrog kev hloov pauv, cov khoom siv tsis ruaj khov, cov hlau lead yuav tawg thiab lwm yam. Tsis tas li ntawd, kuj suav nrog qee yam sab nraud tshwm sim los ntawm. Xws li kub ambient kub, cov av noo ntau dhau los yog muaj zog cuam tshuam cov teeb liab nyob ze thiab lwm yam.
4, saib xyuas.
Koj tuaj yeem kov lub roj teeb, resistor, transistor, integrated block kub nce siab heev. Yog hais tias lub roj teeb tshiab uas tau muab tso rau yog kub, qhia tau hais tias lub Circuit Court yuav luv luv. Tsis tas li ntawd, yuav tsum tau soj ntsuam seb lub Circuit Court puas, desoldering, mechanical puas.
5, ntsuas qhov ua haujlwm voltage ntawm txhua qib.
Tshawb xyuas qhov kev khiav hauj lwm voltage ntawm ntau lub ntsiab lus, thiab sib piv nrog tus nqi ib txwm, ua ntej ntawm tag nrho cov, yuav tsum xyuas kom meej qhov tseeb ntawm qhov siv hluav taws xob, nws yog qhov zoo tshaj plaws los siv ib daim ntawm tib cov qauv los yog cov digital multimeter zoo sib xws rau kev ntsuas thiab sib piv.
