Kev daws teeb meem digital multimeter hauv tsib txoj hauv kev
Digital multimeter yog ib hom kev ntsuas ntsuas uas siv analogue/digital conversion hauv paus ntsiab lus los hloov cov ntsuas kom muaj nuj nqis rau hauv digital kom muaj nuj nqis thiab tso saib cov txiaj ntsig ntsuas hauv daim ntawv digital. Piv nrog rau lub pointer multimeter, digital multimeter muaj qhov zoo ntawm high precision, ceev, loj input impedance, digital zaub, nyeem kom raug, muaj zog tiv thaiv kev cuam tshuam, ntsuas automation thiab yog dav siv. Txawm li cas los xij, yog tias tsis siv kom raug, nws yooj yim ua rau tsis ua haujlwm.
Kev daws teeb meem digital multimeter feem ntau yuav tsum pib los ntawm lub hwj chim mov. Piv txwv li, tom qab tig lub hwj huam mov, yog lub LCD yuan zaub, koj yuav tsum xub xyuas seb qhov voltage ntawm 9V laminated roj teeb tsawg dhau lawm; seb lub roj teeb txhuas puas raug txiav tawm. Nrhiav kev txhaum yuav tsum ua raws li "thawj sab hauv thiab sab nraud, ua ntej yooj yim tom qab qhov nyuaj" kev txiav txim. Kev daws teeb meem digital multimeter tuaj yeem ua raws li hauv qab no.
Digital multimeter daws teeb meem dav dav tsib txoj hauv kev
Ua ntej, kev kuaj pom: koj tuaj yeem kov lub roj teeb, resistor, transistor, integrated block kub nce siab dhau. Yog hais tias lub roj teeb tshiab uas twb tau ntim lawm yog kub, lub Circuit Court yuav luv. Tsis tas li ntawd, lub Circuit Court yuav tsum tau saib xyuas seb puas yog cov hlau tawg, desoldering, mechanical puas, thiab lwm yam.
Thib ob, sim ntsuas qhov ua haujlwm voltage ntawm txhua qib: ntsuas qhov ua haujlwm voltage ntawm txhua lub ntsiab lus, thiab piv nrog tus nqi ib txwm, ua ntej ntawm tag nrho, qhov tseeb ntawm qhov siv hluav taws xob yuav tsum tau ua kom ntseeg tau, nws yog qhov zoo tshaj plaws los siv tib lub qauv lossis zoo sib xws. digital multimeter rau kev ntsuas thiab sib piv.
Thib peb, kev tsom xam waveform: siv lub tshuab hluav taws xob oscilloscope los soj ntsuam cov hluav taws xob hluav taws xob hauv hluav taws xob, amplitude, lub sijhawm (ntau zaus) ntawm cov ntsiab lus tseem ceeb. Piv txwv li, xws li ntsuas seb lub moos oscillator vibration, oscillation zaus yog 40 kHz. Yog hais tias lub oscillator tsis muaj cov zis, qhia tias TSC7106 sab hauv inverter puas lawm, nws kuj yuav yog ib qho khoom siv sab nraud qhib Circuit Court. Saib TSC7106 ko taw {21} waveform yuav tsum yog 50Hz square yoj, txwv tsis pub, nws yuav yog sab hauv 200 zaus faib kev puas tsuaj.
Plaub, kev ntsuas ntawm cov khoom tsis sib xws: rau cov khoom nyob rau hauv qhov kev ua txhaum, kev ntsuas hauv online lossis kev ntsuas offline, qhov ntsuas qhov ntsuas yuav tsum tau txheeb xyuas. Rau kev ntsuas kev tiv thaiv online, yuav tsum xav txog qhov cuam tshuam ntawm nws cov khoom sib txuas.
Thib tsib, kev daws teeb meem zais: zais qhov yuam kev yog hais txog qhov txhaum raug muab zais, qhov ntsuas qhov zoo lossis qhov tsis zoo. 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 connectors, hloov pauv kev sib cuag **, kev ua haujlwm 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.
