Multimeter qhia luv luv Circuit Court tsis kam, nws yog dab tsi?
Ua ntej lub Circuit Court yog thawj zaug powered, kuv siv ib tug multimeter nyob rau hauv lub on/off txoj hauj lwm los ntsuas cov kab rau tej yam luv luv ua ntej kaw lub Circuit Court. Lub sij hawm no yog ib txwm, lub multimeter tsis beep, kuj qhia infinity.
Tom qab ob peb lub hlis ntawm kev siv, kev saib xyuas niaj hnub, nrog lub multimeter los ntawm kev ntsuas luv luv, tus cwj mem ntawm ob kab uas yuav beep rau ib pliag, thiab tom qab ntawd tsis muaj suab nrov, lub vijtsam multimeter qhia ntau dua 60 txog 80 tsis kam. .
Yog li tsis tuaj yeem txiav txim siab seb qhov no yog qhov luv luv lossis tsis, thiab lub rooj vag tuaj yeem raug kaw, nws xav tias tsis paub meej.
1, thaum pib ntawm ob kab tsis muaj kev tiv thaiv, thaum siv rau ib lub sijhawm thiab rov qab los tshuaj xyuas, tua hluav taws xoom kab yeej muaj kev tiv thaiv, thiab lub buzzer horn tseem hu ua, hauv kev xyaum ib txwm, Kuv pom qhov xwm txheej no, qhov kev txiav txim yog raws li nram no:
2, cov xwm txheej paub yog kev teeb tsa sab hauv tsev thiab kev ua haujlwm tom qab muab kev siv cov tsev neeg ntawm cov kab tsis muaj kev tiv thaiv, tus neeg siv yuav siv li cas rau ib lub sijhawm tom qab txoj kab nrog cov kab tsis muaj kev tiv thaiv? Qhov no puas yog xaim xaim? Qhov tshwm sim no yog lub teb chaws tus kws tshaj lij hluav taws xob yog qhov teeb meem rhiab tshaj plaws, nws thawj cov tshuaj tiv thaiv yog siv lub rooj sib tsoo, tsis muaj megohmmeter tsis tuaj yeem pom qhov teeb meem. Qhov tshwm sim no kuj zoo ib yam li cov kws kho mob laus thiab cov kws kho mob hluas, cov kws kho mob laus mloog cov lus tsis txaus siab yuav paub tias muaj kab mob dab tsi, cov kws kho mob hluas yog vam khom cov cuab yeej.
3, Kuv feem ntau siv lub teeb txuag hluav taws xob ntawm 400V electrodeless capacitor ua tus resistor, cov roj fluorescent qub ntawm lub raj neon coj mus rau qhov ci los ntawm cov koob thaum qhov ntsuas, vim tias daim ntawv qhia no hauv lub qhov (socket) tau pom. Ib qho electrodeless capacitor muaj tus yam ntxwv, tuaj yeem khaws qee qhov nqi, yog tias koj dhau hluav taws xob, tsis txhob mloog rau tib neeg tes nrog hluav taws xob induction.
4, muab ob npaug rau-xyuas qhov kev tiv thaiv, tsuas yog ob qho kev xav, thiab tom qab ntawd tsis muaj ntxiv, uas yog, kuv tau hais txog qhov piv txwv saum toj no.
5, thaum tus neeg siv lub qhov (socket) muaj lub qhov (socket) lub xov tooj ntawm tes, lub qhov (socket) lub xov tooj ntawm tes no muaj qhov hloov pauv thiab qhov taw qhia, tom qab kaw lub qhov hluav taws xob tseem ceeb, lub qhov (socket) lub xov tooj ntawm tes no tsis tau muab tshem tawm, (Kuv qhov kev paub dhau los, tsab xov xwm hais txog hluav taws xob tau hais kom hu rau txhua lub ntsaws thiab indicators) yog tias qhov ntsuas no yog tshwm sim los ntawm qhov hluav taws kub thiab xoom xaim txuas nrog.
Kuv tsis paub tias kab ntawd yog dab tsi specification qauv, ntev, erection ib puag ncig, cov kab tshiab tsis muaj suab tsis muaj zog qhia tau hais tias nws yog ib txwm zoo heev, nrog rau cov hlau energized vim hais tias ntawm inter-wire hluav taws xob yog ib qho yooj yim rau digital multimeter cuam tshuam. , nws raug pom zoo tias cov xaim raug kuaj rau kev kho luv luv thiab tom qab ntawd ntsuas, lossis nrog lub ntsuas pob zeb los ntsuas qhov tseeb dua.
Yog tias koj xav ntsuas tus nqi tiv thaiv tiag tiag, koj yuav tsum siv lub rooj sib tsoo lossis lub rooj tiv thaiv rwb thaiv tsev, thiab tom qab ntawd koj yuav tsum tau hloov kho rau cov iav tiv thaiv, dab tsi yog qhov teeb meem nrog tus nqi tiv thaiv ntawm lub iav tawm?
Tseem xav ntsuas tus nqi tiv thaiv, feem ntau xav kom tshem tawm lub zog, thiab tom qab ntawd tshem tawm cov load, txwv tsis pub nws tsis muaj txiaj ntsig los ntsuas ncaj qha.
Piv txwv li, yog tias nws tshwm sim los ntawm kev sib txuas ntawm xoom xaim thiab hluav taws xob hluav taws xob tsuas yog lub teeb incandescent xwb, ces ntsuas tawm yog qhov tsis kam ntawm lub teeb incandescent filament, yog tias nws yog lub teeb fluorescent, ces ntsuas tawm yog qhov sib npaug ntawm qhov sib npaug. fluorescent teeb nyob rau hauv Circuit Court ntawm tag nrho cov kuj.
