Kho Txoj Kev thiab Kev Txawj Ntse rau Fluke Digital Multimeters
Fluke cov cuab yeej siv digital muaj qhov nkag siab zoo thiab raug, thiab lawv cov ntawv thov yuav luag txhua qhov chaw lag luam. Txawm li cas los xij, vim muaj ntau qhov xwm txheej ntawm nws qhov ua tsis tau zoo thiab qhov siab randomness ntsib teeb meem, kho nws yog qhov nyuaj. Kuv tau sau qee qhov kev kho kho uas tau sau los ntawm ntau xyoo ntawm kev ua haujlwm rau koj siv thiab vam tias yuav pab tau rau txhua tus.
1, Cov ntsiab lus ntawm kev kho cov txheej txheem
Nrhiav qhov txhaum yuav tsum pib nrog sab nraud thiab tom qab ntawd sab hauv, pib nrog qhov yooj yim thiab tom qab ntawd qhov nyuaj, rhuav tshem tag nrho rau hauv me me thiab tsom mus rau kev tawg. Cov txheej txheem tuaj yeem kwv yees faib ua pawg hauv qab no:
1. Txoj kev hnov lus cia siab rau qhov kev nkag siab ntawm kev nkag siab ncaj qha los txiav txim qhov ua txhaum. Los ntawm kev tshuaj xyuas qhov muag, nws tuaj yeem kuaj pom cov teeb meem xws li cov xov hlau tawg, desoldering, luv Circuit Court hauv av, tawg fuse hlab, cov khoom siv hluav taws xob, kev puas tsuaj rau cov khoom siv, tooj liab ntawv ci warping thiab tawg ntawm cov ntawv luam tawm, thiab lwm yam; Koj tuaj yeem kov qhov kub thiab txias ntawm lub roj teeb, resistor, transistor, thiab kev sib xyaw ua ke, thiab xa mus rau daim duab hluav taws xob kom pom qhov ua rau qhov kub tsis txawv txav. Tsis tas li ntawd, koj tuaj yeem tshawb xyuas los ntawm txhais tes seb cov khoom puas yog xoob, puas yog cov pins sib xyaw ua ke tau ruaj khov, thiab seb qhov hloov pauv hloov tau daig; Koj tuaj yeem hnov thiab hnov cov suab txawv txawv lossis tsw ntxhiab.
2. Txoj kev ntsuas qhov ntsuas hluav taws xob ntsuas seb qhov ua haujlwm voltage ntawm txhua qhov tseem ceeb yog qhov qub, uas tuaj yeem txheeb xyuas qhov ua txhaum ntawm qhov taw tes sai. Ntsuas qhov kev khiav hauj lwm voltage, siv voltage, thiab lwm yam ntawm A / D converter.
3. Txoj kev luv luv Circuit Court feem ntau yog siv rau hauv kev tshuaj xyuas ntawm A / D converters tau hais ua ntej, thiab txoj kev no feem ntau siv los kho cov twj tsis muaj zog thiab micro hluav taws xob.
4. Txoj kev rhuav tshem Circuit Court cuam tshuam qhov tsis txaus ntseeg los ntawm tag nrho lub tshuab lossis lub tshuab hluav taws xob. Yog hais tias qhov txhaum ploj mus, nws qhia tau hais tias qhov txhaum yog nyob rau hauv lub disconnected Circuit Court. Txoj kev no yog qhov tsim nyog rau cov xwm txheej uas muaj luv luv hauv Circuit Court.
5. Thaum qhov txhaum tau nqaim mus rau ib qho lossis ob peb yam, nws tuaj yeem ntsuas hauv online lossis offline siv txoj kev ntsuas kev tivthaiv. Yog tias tsim nyog, hloov nrog cov khoom zoo. Yog tias qhov txhaum ploj mus, nws qhia tau hais tias cov khoom puas lawm.
6. Kev cuam tshuam txoj kev siv tib neeg induced voltage raws li lub teeb liab cuam tshuam los soj ntsuam cov kev hloov hauv LCD zaub, feem ntau yog siv los xyuas seb lub input Circuit Court thiab cov zaub ib feem puas lawm.
2, Kho kev txawj ntse
Rau cov cuab yeej faulty, thawj kauj ruam yog los xyuas thiab paub qhov txawv ntawm qhov kev ua txhaum yog qhov tshwm sim (tag nrho cov haujlwm tsis tuaj yeem ntsuas) lossis tus kheej (tus kheej lub luag haujlwm lossis tus kheej ntau yam), thiab tom qab ntawd sib txawv qhov xwm txheej thiab daws nws raws li.
Yog tias txhua lub zog tsis tuaj yeem ua haujlwm, lub hwj chim muab hluav taws xob thiab A / D converter circuit yuav tsum tau xyuas kom zoo. Thaum kuaj xyuas cov khoom siv hluav taws xob, tshem tawm cov roj teeb uas tau teem tseg, nias lub hwj huam hloov, txuas qhov kev sojntsuam zoo rau qhov tsis zoo ntawm lub ntsuas hluav taws xob, thiab txuas cov kev sojntsuam tsis zoo rau lub zog zoo (rau digital multimeter). Tig qhov hloov mus rau qhov ntsuas diode. Yog hais tias cov zaub qhia qhov zoo voltage ntawm lub diode, nws qhia tau hais tias lub hwj chim mov yog zoo. Yog tias qhov sib txawv loj, nws qhia tau hais tias muaj teeb meem nrog cov khoom siv hluav taws xob. 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 kev cuam tshuam luv luv, nws yuav tsum siv txoj hauv kev sib tsoo kom maj mam txiav cov khoom siv hluav taws xob, nrog rau kev tsom mus rau kev tshuaj xyuas lub tshuab ua haujlwm, lub sijhawm, thiab A / D converter.
