Yuav ua li cas siv lub vijtsam digital los tso saib ntau tus cwj mem hluav taws xob
Neon noob cwj mem
Qhov loj tshaj plaws ntawm neon teeb hluav taws xob cwj mem yog thaum tus cwj mem kov cov khoom siv, lub teeb neon yuav teeb, thiab lub taub ntawm tus cwj mem tsuas yog me me, uas tuaj yeem siv thaum muaj xwm txheej ceev. Tam sim no muaj cov khoom lag luam hauv kev lag luam uas tuaj yeem tshem tau thiab muaj ob lub taub hau uas tuaj yeem hloov tau ntawm qhov xav tau, uas yog qhov ua tau zoo heev.
Cov lus qhia
Tuav tag nrho ib feem ntawm tus cwj mem hluav taws xob nruab nrab ntawm koj tus ntiv tes ntiv tes thiab ntiv tes nruab nrab, nias cov hlau nyob tom qab kawg ntawm tus cwj mem hluav taws xob nrog koj tus ntiv tes xoo kom tau txais hluav taws xob poob siab, thiab maj mam kov cov khoom them nrog lub hau ntawm tus cwj mem.
txoj cai ua haujlwm
Siv tib neeg lub cev ua ib lub voj voog, nws teeb thaum lub zog nce mus txog qhov ua haujlwm ntawm lub teeb neon.
Cov kev ceev faj
1. Ua ntej kuaj hluav taws xob, thawj zaug lees paub qhov zoo ntawm tus cwj mem hluav taws xob ntawm cov khoom nyob kom paub tseeb tias tsis muaj qhov yuam kev.
2. Thaum kuaj hluav taws xob, tsis txhob kov cov hlau ntawm lub hauv ntej kawg ntawm tus cwj mem hluav taws xob nrog koj lub cev kom tsis txhob muaj hluav taws xob poob.
3. Ua tib zoo nyeem cov lus qhia ua ntej siv thiab ua tib zoo saib xyuas qhov ntsuas ntsuas. Qee qhov yog 50v-500v, thiab qee qhov yog 110v500v.
4. Ua tib zoo saib qhov txawv ntawm AC thiab DC.
5. Thaum tsis ntseeg siab, siv lub tshuab multimeter thiab tsis txhob siv sijhawm.
6. Lub cev yog insulated los ntawm lub ntiaj teb.
digital display cwj mem.
Tus cwj mem digital yuav tso saib qhov voltage ntawm qhov screen thaum ntsuas. Feem ntau tus lej loj tshaj plaws tshwm sim ntawm qhov screen ntawm tus cwj mem yog qhov ntsuas qhov ntsuas hluav taws xob. Tab sis kuv ib txwm xav tias me ntsis tsis ntseeg.
Cov lus qhia.
Muaj ob qhov kev sim nyees khawm ntawm tus cwj mem, ntsuas ncaj qha thiab induction breakpoint test. Thaum peb siv nws, peb tsuas yog yuav tsum xaiv kov ob lub khawm no raws li lub hom phiaj ntawm peb tus kheej kev sim.
Ntsuas qhov txuas ntxiv.
Qhov kev ua haujlwm no yog qhov kom zoo dua ntawm cov cwj mem digital tshaj li neon noob cwj mem. Thaum ntsuas, koj yuav tsum tau txiav lub hwj huam mov, tuav ib kawg ntawm cov hlau nrog ib txhais tes, kov lub sensor khawm nrog koj tus ntiv tes xoo ntawm qhov tod tes, thiab kov lwm qhov kawg ntawm cov hlau nrog me ntsis ntawm tus cwj mem hluav taws xob. Lub teeb lub teeb ci, qhia tias cov hlau txuas nrog.
Ntsuas cov ntsiab lus tawg.
Qhov kev ua haujlwm no tsis yooj yim rau kev siv, tshwj xeeb tshaj yog cov tub ntxhais cables, uas tsis tuaj yeem ntsuas thiab tsis nkag siab.
Txawm hais tias hom hluav taws xob cwj mem no ncaj qha qhia qhov hluav taws xob, nws qhov tseeb yog questionable. Ntau tus phooj ywg hluav taws xob tau tshaj tawm tias qee zaum nws tsis yog txhua yam thiab tseem ua rau kev txiav txim tsis raug.
Lub teeb muaj zog heev kom pom meej, thiab lub teeb tsaus heev kom pom meej. Cov ntawv nyeem qee zaum flicker rau thiab tawm. Qhov no yog nws qhov shortcoming. Yog li kuv feem ntau tsis siv cov cwj mem digital.
Lub suab thiab lub teeb tswb sensor cwj mem.
Hom hluav taws xob cwj mem no yog ib yam khoom tshiab tso tawm xyoo tas los no. Nws yog qhov yooj yim heev los txiav txim seb qhov khoom puas raug them. Nws tseem yog qhov tseeb kom paub qhov txawv ntawm xoom nyob kab. Nws tsis txwv los ntawm ambient teeb yam. Nws yog qhov tshwj xeeb tshaj yog siv tau rau kev ntsuas qhov tawg. Qhov tsis zoo yog tias nws tsis pom qhov voltage. Tsawg kawg kom deb li deb, qhov kuv siv tsis muaj qhov haujlwm no.
Cov cwj mem hluav taws xob no muaj tag nrho lub cev yas casing kom txo tau qhov hluav taws xob poob siab. Nws yog super yooj yim siv. Thaum ntsuas, qhib lub hwj chim ua ntej. Ib txhia ntawm lawv tsuas yog nias thiab tuav lub hwj chim khawm. Yog tias qhov hluav taws xob hluav taws xob muaj zog, lub tswb yuav tshwm sim yam tsis tau kov cov khoom raug them, uas tseem tuaj yeem txo qhov muaj peev xwm ntawm kev them nyiaj.
Los ntawm tus kheej kev paub dhau los, peb hom hluav taws xob cwjmem saum toj no muaj lawv tus kheej qhov zoo, tab sis lawv tsuas tuaj yeem kuaj seb cov khoom puas raug them, thiab tsis tuaj yeem txiav txim siab qhov voltage. Thaum peb yuav tsum ntsuas qhov tseeb qhov hluav taws xob ntawm cov khoom siv, lub multimeter yog qhov txhim khu kev qha.
