Kho lub teeb chav pw hauv qab ob chav tswj kev hloov nrog lub cwj mem hluav taws xob thiab lwm yam.
Lub teeb hauv chav pw dheev tawm mus thiab txiav txim siab kho nws. Lub teeb yog tswj los ntawm ob-tswj mus. Lub teeb Ameslikas muaj qhov sib txawv ntawm qhov ci. Muaj peb lub teeb taub hau rau, N siv lead ua teeb rau, thiab tag nrho cov teeb nyob rau. Nws tau kwv yees tias cov khoom siv hluav taws xob hauv lub teeb yog kev laus, thiab nws tau npaj yuav hloov mus rau lub teeb taub hau nkaus xwb, thiab cov haujlwm dazzling ntawm lub teeb me me tsis muaj txiaj ntsig rau peb.
Multi-function test cwj mem (digital display type) muab faib ua 12V, 36V, 55V, 110V, 220V, tuaj yeem ntsuas qhov hloov pauv tam sim no thiab ncaj qha tam sim no (12-250V), thiab muaj cov haujlwm ntawm kev ntsuas hluav taws xob induction (tes kev tiv tauj yog "Induction" hauv daim duab saum toj no xxxx Test"), qhov siab tshaj qhov voltage ntau yog tso tawm raws li qhov kwv yees qhov ntsuas hluav taws xob ntsuas thaum lub sijhawm ntawd, qhov ntsuas inductive breakpoint yog siv los ntsuas qhov twg cov cable tawg, nws tau hais tias nws tsis tuaj yeem. muab tso rau hauv dej, thiab nws yuav raug tshaj tawm tias nws puas tau muab tso rau hauv dej (qhia tias nws tsis nkag siab, leej twg tuaj yeem sim nws).
Yog tias nws tshwm sim li 12V36V55V110V220, nws txhais tau tias qhov voltage yog 220 volts; Yog tias nws tshwm sim li 12V36V55V110, nws txhais tau tias qhov voltage yog 110 volts; Yog tias nws tau tso tawm ua 12V36V55, nws txhais tau hais tias qhov voltage yog 55 volts; Yog tias nws tau tso tawm ua 12V36, nws txhais tau tias qhov hluav taws xob yog 36 volts; Yog tias nws tshwm sim li 12, nws txhais tau tias qhov voltage yog 12 volts.
Thaum ntsuas qhov hloov pauv tam sim no, nias koj tus ntiv tes ntawm qhov kev sib cuag uas raug kuaj ncaj qha ("Direct Test"); Thaum ntsuas qhov hluav taws xob ncaj qha, nias thiab tuav "Direct Test", nias qhov zoo electrode ntawm lub roj teeb nrog rau sab tes, thiab nias qhov tsis zoo electrode nrog tus cwj mem taub.
Lub hauv paus ntsiab lus ua haujlwm ntawm ob hom hluav taws xob cwj mem yog tib yam: Ohm txoj cai I=U / R thiab tag nrho cov kev sib raug zoo ntawm cov kab hluav taws xob: R=R1 (tib neeg) ntxiv rau R2 (siv hluav taws xob) . Kev ua haujlwm ntawm tib neeg lub cev feem ntau me me, feem ntau tsuas yog ob peb puas mus rau ob peb txhiab ohms, thaum qhov kev tawm tsam hauv tus cwj mem xeem feem ntau yog hais txog ntau megohms. Tam sim no los ntawm kev xeem tus cwj mem (uas yog, tam sim no los ntawm tib neeg lub cev) yog qhov me me, feem ntau tsawg dua 1 mA, Thaum cov tam sim no me me dhau los ntawm tib neeg lub cev, nws tsis ua mob rau tib neeg, tab sis nws tuaj yeem ua rau hluav taws xob. cwj mem zaub (los yog lub teeb neon yog nyob rau, los yog cov duab digital).
Qhov hluav taws xob ntawm cov hlau nyob yuav tsum yog 220V. Thaum qhov hloov pauv tau qhib, cov kab nruab nrab yuav tsum tsis muaj qhov hluav taws xob; Thaum lub kaw lus kaw, cov kab nruab nrab yuav pom qhov hluav taws xob ntawm 55 volts lossis tsawg dua (txuas nrog cov khoom siv hluav taws xob), lossis 110V (qhov no yog cov khoom siv hluav taws xob ntawm lub teeb hauv kuv lub tsev). Cov khoom tsis ua hauj lwm qhia tau hais tias 110V, nws kuj yuav yog qhov nruab nrab ntawm cov hlau nyob yog thim rov qab, luv luv, them sai sai).
Nrog rau tus cwj mem hluav taws xob, ua ntej txiav txim siab seb puas muaj teeb meem nrog kev tswj xyuas ob, thiab thaum kawg xyuas seb puas muaj teeb meem nrog lub teeb ntawm lub ru tsev (lub teeb nyob hauv nruab nrab ntawm lub ru tsev yog qhov nyuaj rau kev khiav lag luam). Tsis ntev, nws tau raug kuaj xyuas tias tsis muaj teeb meem nrog kev xaim ntawm kev tswj ob npaug, thiab tsis muaj teeb meem ntawm kev qhib thiab tawm. Dual tswj txhais tau hais tias 2 pawg ntawm cov keyboards tuaj yeem tswj tau 1 lub teeb yam tsis muaj kev cuam tshuam rau ib leeg (uas yog, hloov ntawm lub qhov rooj ntawm chav pw, hloov ntawm lub txaj, thiab tswj lub teeb saum toj ntawm chav pw tib lub sijhawm)
Kuv yuav tsum disassemble lub ru tsev teeb. Feem ntau muaj 3 yam khoom siv hluav taws xob hauv lub teeb. Raws li cov lus qhia ntawm lub plhaub, kuv tsuas paub qhov kwv yees muaj nuj nqi (seg tswj (sib npaug rau outputting 3 lub xeev), hloov mus rau DC 3V, AC 12V, thiab lwm yam), vim kuv tsuas yog yuav tsum tau siv 3 lub zog txuag teeb nrog 220V. input, Kuv tshem tawm 3 cov khoom siv hluav taws xob no thiab txuas ntxiv siv cov xov hlau sab hauv. Cov xaim hauv lub teeb lub qhov (socket) thiab cov xaim ntawm phab ntsa yog fastened los ntawm screwing, yog li kuv tau sawv ntawm tus ntaiv ib leeg, thiab nws siv zog heev los kho nws.
