Kev daws teeb meem yooj yim ntawm kev ua yuam kev ntawm digital multimeter
Hais txog kev daws teeb meem ntawm kev ua txhaum ntawm cov multimeters, raws li peb txhua tus paub, kev daws teeb meem ntawm digital multimeters feem ntau yuav tsum pib nrog lub hwj huam mov, suav nrog kev tshuaj xyuas cov duab digital multimeters, nrhiav kom pom kev ua haujlwm voltages ntawm txhua theem, waveform tsom xam, ntsuas. tivthaiv parameter thiab zais teeb meem txoj kev, thiab lwm yam.
Txoj kev daws teeb meem rau kev ua txhaum ntau ntawm digital multimeters
Kev daws teeb meem digital multimeter feem ntau yuav tsum pib nrog lub hwj chim mov. Piv txwv li, tom qab lub hwj chim qhib, yog tias cov kua siv lead ua kua cell qhia, koj yuav tsum xub xyuas seb qhov hluav taws xob ntawm 9V stacked roj teeb tsawg dhau lawm; seb lub roj teeb leads puas raug txiav.
Kev daws teeb meem yuav tsum ua raws li cov theem ntawm "hauv thawj, thawj zaug yooj yim thiab tom qab ntawd nyuaj". Kev daws teeb meem ntawm digital multimeter tuaj yeem ua raws li hauv qab no.
1. Kev tshuaj xyuas qhov tshwm sim
Koj tuaj yeem kov los ntawm tes seb qhov kub ntawm cov roj teeb, cov resistors, transistors, thiab cov blocks sib xyaw yog siab dhau. Yog tias lub roj teeb uas tau nruab tshiab yog kub, lub voj voog yuav luv. Nyob rau hauv tas li ntawd, lub Circuit Court yuav tsum tau soj ntsuam rau disconnection, desoldering, mechanical puas, thiab lwm yam.
2. Kev kuaj xyuas qhov ua haujlwm voltage ntawm txhua qib
Tshawb xyuas qhov ua haujlwm voltage ntawm txhua qhov taw tes thiab sib piv nrog tus nqi ib txwm muaj. Ua ntej, xyuas qhov tseeb ntawm qhov siv voltage. Nws yog qhov zoo tshaj plaws los siv digital multimeter ntawm tib tus qauv lossis zoo sib xws los ntsuas thiab sib piv.
3. Kev tsom xam Waveform
Siv lub tshuab hluav taws xob oscilloscope los soj ntsuam qhov voltage waveform, amplitude, lub sij hawm (frequency), thiab lwm yam ntawm txhua qhov tseem ceeb ntawm lub voj voog.
Piv txwv li, yog lub moos oscillator pib oscillate thiab 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 cov khoom sab nraud yuav qhib.
Saib xyuas tias lub waveform ntawm {21} ko taw ntawm TSC7106 yuav tsum yog 50Hz square nthwv dej, txwv tsis pub, sab hauv 200 zaus faib yuav raug puas tsuaj.
Plaub, qhov ntsuas qhov ntsuas qhov ntsuas
Rau cov khoom nyob rau hauv qhov kev ua txhaum ntau, ua kev ntsuas hauv online lossis off-line, thiab txheeb xyuas qhov ntsuas qhov ntsuas. Rau kev ntsuas kev tiv thaiv hauv online, kev cuam tshuam ntawm cov khoom sib txuas ua ke nrog nws yuav tsum tau txiav txim siab.
5. Kev daws teeb meem zais
Recessive faults hais txog qhov txhaum uas tshwm sim thiab ploj mus ib ntus, thiab qhov ua txhaum ntawm qhov ntsuas yog qhov zoo thiab qhov tsis zoo. Qhov kev ua txhaum no yog qhov nyuaj dua, thiab cov laj thawj feem ntau suav nrog cov pob qij txha, xoob, xoob cov khoom sib txuas, kev sib cuag tsis zoo ntawm kev hloov pauv hloov, kev ua haujlwm tsis ruaj khov, thiab cov hlau lead yuav tawg tsis tu ncua.
Tsis tas li ntawd, nws kuj suav nrog qee yam sab nraud. Piv txwv li, ambient kub siab dhau lawm, cov av noo siab dhau lawm, los yog muaj cov teeb liab muaj zog cuam tshuam nyob ze.
