Kev daws teeb meem thiab tuav cov txuj ci ntawm digital multimeter
1. Kho txoj kev ntawm digital multimeter
Thaum nrhiav kev txhaum, koj yuav tsum pib los ntawm sab nraud thiab tom qab ntawd sab hauv, ua ntej yooj yim thiab tom qab ntawd nyuaj, tawg tag nrho rau hauv qhov chaw, thiab ua kom tawg ntawm cov ntsiab lus tseem ceeb. Cov txheej txheem tuaj yeem kwv yees faib ua pawg hauv qab no:
1. Txoj kev xav
Siv qhov kev nkag siab los txiav txim ncaj qha rau qhov ua rau tsis ua haujlwm. Los ntawm kev tshuaj xyuas qhov muag, koj tuaj yeem pom xws li kev sib txuas, desoldering, luv luv Circuit Court, tawg fuse tube, burnt Cheebtsam, mechanical puas, tooj liab ntawv nyiaj lifting thiab puas nyob rau hauv lub luam Circuit Court, thiab lwm yam.; Koj tuaj yeem kov qhov kub thiab txias ntawm lub roj teeb, resistors, transistors, thiab kev sib xyaw ua ke, thiab koj tuaj yeem xa mus rau daim duab kos duab kom paub seb yog vim li cas rau qhov kub tsis txawv txav.
Tsis tas li ntawd, los ntawm txhais tes, koj tuaj yeem tshawb xyuas seb cov khoom puas yog xoob, seb cov pins sib xyaw ua ke tau ruaj khov, thiab seb qhov hloov pauv hloov yog daig; koj tuaj yeem hnov thiab hnov txog seb puas muaj suab txawv txav thiab tsw.
2. Txoj kev ntsuas hluav taws xob
Kev ntsuas seb qhov ua haujlwm voltage ntawm txhua qhov tseem ceeb yog qhov qub tuaj yeem tshawb pom qhov yuam kev. Xws li ntsuas qhov ua haujlwm voltage thiab siv voltage ntawm A / D converter.
3. Txoj kev luv luv
Nyob rau hauv txoj kev tshawb xyuas A / D converter uas tau hais los saum toj no, feem ntau siv luv luv-circuit txoj kev, thiab txoj kev no feem ntau siv thaum kho cov twj tsis muaj zog thiab micro-hluav taws xob.
4. Txoj kev rhuav tshem Circuit Court
Tshem tawm qhov tsis txaus ntseeg los ntawm tag nrho lub tshuab lossis lub tshuab hluav taws xob. Yog hais tias qhov txhaum ploj mus, nws txhais tau hais tias qhov txhaum nyob rau hauv lub disconnected Circuit Court. Cov qauv no feem ntau haum rau qhov xwm txheej uas muaj qhov luv luv hauv Circuit Court.
5. Kev ntsuas cov txheej txheem
Thaum qhov ua txhaum tau nqaim mus rau ib lossis ob peb yam, nws tuaj yeem ntsuas hauv online lossis offline. Yog tias tsim nyog, hloov nws nrog qhov zoo. Yog tias qhov txhaum ploj mus, cov khoom tawg.
6. Txoj kev cuam tshuam
Siv tib neeg lub cev induced voltage raws li lub teeb liab cuam tshuam los soj ntsuam cov kev hloov ntawm cov kua siv lead ua kua zaub. Nws yog feem ntau siv los xyuas seb qhov input Circuit Court thiab cov khoom siv puas zoo lawm.
Thib ob, kev txawj kho digital multimeter
Rau cov cuab yeej faulty, thawj zaug xyuas thiab txiav txim seb qhov kev ua txhaum tshwm sim puas muaj tshwm sim (tag nrho cov haujlwm tsis tuaj yeem ntsuas) lossis tus kheej (kev ua haujlwm ntawm tus kheej lossis tus kheej ntau), thiab tom qab ntawd paub qhov txawv qhov xwm txheej thiab daws nws cov tsos mob.
1. Yog tias txhua lub zog tsis ua haujlwm, tsom mus xyuas lub zog hluav taws xob thiab A / D converter circuit.
Thaum kuaj xyuas cov khoom siv hluav taws xob, koj tuaj yeem tshem tawm cov roj teeb laminated, nias lub hwj huam hloov, txuas qhov kev ntsuam xyuas zoo ua rau qhov tsis zoo ntawm lub zog hluav taws xob ntawm lub ntsuas hluav taws xob nyob rau hauv kev sim, thiab qhov ntsuas tsis zoo ua rau lub zog zoo (rau digital. multimeters), thiab hloov mus rau qhov ntsuas diode. Yog hais tias qhov hluav taws xob pem hauv ntej ntawm lub diode yog siab dua, nws txhais tau hais tias lub hwj huam mov yog qhov zoo. Yog hais tias qhov sib txawv loj, nws txhais tau hais tias muaj teeb meem nrog lub hwj huam mov.
Yog tias muaj qhov qhib Circuit Court, tsom mus rau kev kuaj xyuas lub hwj chim hloov thiab cov roj teeb coj.
Yog tias muaj qhov luv luv, koj yuav tsum siv txoj kev qhib Circuit Court kom maj mam txiav cov khoom siv hluav taws xob, thiab tsom mus rau kev kuaj xyuas lub tshuab ua haujlwm, lub sijhawm thiab A / D converter. Nyob rau hauv qhov kev tshwm sim ntawm ib tug luv luv Circuit Court, feem ntau ntau tshaj ib tug integrated tivthaiv yog puas.
