Yuav ua li cas nrhiav tau ib tug luv luv Circuit Court nrog ib tug multimeter (6-kauj ruam qhia)
Txheem
Koj puas tau ntsib teeb meem ntawm qhov luv luv thaum ua haujlwm nrog cov khoom siv hluav taws xob lossis cov khoom siv? Thaum ib lub voj voog luv luv ua rau koj lub voj voog hluav taws xob puas tsuaj los yog lub rooj tsav xwm hauv Circuit Court, nws yuav muaj teeb meem ntau dua. Kev txheeb xyuas thiab kho qhov luv luv yog qhov tseem ceeb.
Txawm hais tias muaj ntau txoj hauv kev los txheeb xyuas qhov luv luv, siv multimeter yog ib qho yooj yim tshaj plaws. Yog li ntawd, peb tau ua qhov kev piav qhia ntawm yuav ua li cas nrhiav tau ib qho luv luv Circuit Court nrog multimeter.
Qhov luv luv Circuit Court yog dab tsi?
Ib qho luv luv Circuit Court yog ib qho cim ntawm cov hlau tawg lossis tawg, ua rau muaj kev ua haujlwm tsis zoo hauv cov hluav taws xob. Nws yog tsim thaum lub xaim nqa tam sim no los rau hauv kev sib cuag nrog nruab nrab lossis hauv av hauv Circuit Court.
Tsis tas li ntawd, nws tuaj yeem yog lub cim ntawm lub voj voog luv yog tias koj pom cov fuses tshuab tsis tu ncua lossis lub Circuit Court breaker tripping nquag. Thaum lub Circuit Court raug tsim, koj tuaj yeem hnov suab nrov nrov.
Lub multimeter yog ib qho ntawm cov cuab yeej yooj yim uas koj tuaj yeem siv los xyuas cov luv luv hauv koj lub tsev cov xaim. Nrog nws, koj tuaj yeem tshawb xyuas cov teeb meem hluav taws xob xws li luv luv rau hauv av. Ib tug multimeter tuaj yeem tshawb xyuas qhov luv luv ntawm lub rooj tsav xwm Circuit Court, xws li ntawm lub khoos phis tawj desktop. Tsis tas li ntawd, nws tseem tuaj yeem kuaj xyuas qhov luv luv hauv koj lub tsheb cov xov hluav taws xob.
Cov kauj ruam los nrhiav qhov luv luv nrog lub digital multimeter
Los ntawm kev kho lub luv luv Circuit Court kom sai li sai tau, koj yuav txo tau qhov kev pheej hmoo ntawm kev puas tsuaj rau cov hlau thiab rwb thaiv tsev thiab tiv thaiv lub Circuit Court breaker los ntawm hlawv tawm. (1)
Txhawm rau nrhiav qhov luv luv nrog lub multimeter, ua raws li cov kauj ruam no:
Kauj Ruam 1: Nyob nyab xeeb thiab npaj
Nws yog ib qho tseem ceeb heev kom paub tseeb tias txhua yam ua tau zoo ua ntej siv multimeter los txiav txim qhov luv luv. Qhov no ua kom paub tseeb tias tsis yog koj lub voj voog hluav taws xob lossis koj lub multimeter puas raug puas tsuaj thaum tshawb nrhiav qhov luv luv.
Ua ntej tshawb xyuas ib yam dab tsi, xyuas kom tseeb tias koj cov hluav taws xob hluav taws xob tsis raug. Qhov no suav nrog tshem cov roj teeb thiab lub hwj chim adapters.
Nco ntsoov: Yog tias koj tsis tua txhua lub zog rau lub voj voog ua ntej kuaj nws, koj tuaj yeem tau txais hluav taws xob loj lossis hluav taws xob poob siab. Yog li ntawd, muab ob npaug rau xyuas tias cov hluav taws xob hauv Circuit Court yog tawm.
Kauj Ruam 2 Qhib koj lub multimeter thiab teeb tsa.
Qhib lub multimeter tom qab muab ob npaug rau xyuas txhua yam muaj kev nyab xeeb siv. Tom qab ntawd siv lub pob khawm hloov los teeb tsa mus rau qhov kev sim txuas ntxiv lossis hom kev tawm tsam, nyob ntawm qhov muaj peev xwm ntawm koj lub multimeter.
Tswv yim: Yog tias koj lub multimeter muaj lwm qhov chaw tiv thaiv, nws raug nquahu kom xaiv qhov ntsuas qis tshaj plaws.
Kauj Ruam 3: Tshawb xyuas thiab kho lub Multimeter
Txhawm rau kom ntseeg tau tias koj lub multimeter yuav muab tag nrho cov kev ntsuas koj xav tau, koj yuav tsum sim thiab ntsuas nws ua ntej siv. Txhawm rau ua qhov no, txuas cov lus qhia sojntsuam ntawm koj lub multimeter.
Yog tias nws nyob rau hauv hom tsis kam, qhov kev nyeem ntawv ntawm koj lub multimeter yuav tsum yog 0 lossis ze rau xoom. Yog tias qhov kev nyeem ntawv multimeter siab dua li xoom, ntsuas nws kom thaum ob qhov kev sojntsuam kov, tus nqi yuav yog xoom. Ntawm qhov tod tes, yog tias nws nyob hauv hom txuas ntxiv, lub teeb yuav flash lossis buzzer yuav suab thiab kev nyeem ntawv yuav yog 0 lossis ze rau xoom.
Kauj Ruam #4: Nrhiav cov Schematic Cheebtsam
Tom qab teeb tsa thiab ntsuas lub ntsuas ntsuas, koj yuav tsum nrhiav thiab txheeb xyuas cov khoom siv hluav taws xob uas koj yuav tau sim rau luv luv circuits.
Qhov hluav taws xob tsis kam ntawm cov khoom no, feem ntau yuav, yuav tsum tsis txhob sib npaug rau xoom. Piv txwv li, lub tswv yim ntawm lub suab amplifier nyob rau hauv koj chav nyob ib sab ntawm koj lub TV yuav luag yeej muaj ib tug impedance ntawm ob peb puas ohms (tsawg kawg).
Lawm: Xyuas kom tseeb tias txhua yam khoom muaj tsawg kawg yog qee qhov kev tiv thaiv thaum xaiv cov khoom no, txwv tsis pub nws yuav nyuaj rau kev kuaj xyuas qhov luv luv.
Kauj Ruam 5: Tshawb xyuas Circuit Court
Tom qab nrhiav cov khoom siv no uas koj yuav sim rau lub voj voog luv luv, txuas cov xov tooj liab thiab dub ntawm koj lub multimeter mus rau lub voj voog.
Cov hlau taub ntawm qhov kev sojntsuam dub yuav tsum tau txuas nrog hauv av lossis hluav taws xob hluav taws xob chassis.
Tom qab ntawd txuas cov hlau taub ntawm qhov kev sojntsuam liab rau cov khoom uas koj tab tom sim lossis rau thaj tsam koj xav tias luv luv. Xyuas kom tseeb tias ob qhov kev sojntsuam yog nyob rau hauv kev sib cuag nrog cov khoom siv hlau xws li cov hlau, cov khoom siv lead ua, lossis cov ntawv ci PCB.
Kauj Ruam 6: Tshawb xyuas cov zaub multimeter
Thaum kawg, xyuam xim rau kev nyeem ntawv ntawm multimeter's zaub thaum koj nias qhov liab thiab dub probes tiv thaiv cov hlau ntawm lub voj voog.
- Hom Kev Tiv Thaiv - Yog tias qhov kev tiv thaiv qis thiab qhov kev nyeem ntawv yog xoom lossis ze rau xoom, ntsuas tam sim no ntws los ntawm nws thiab lub voj voog txuas ntxiv. Txawm li cas los xij, yog tias muaj qhov luv luv, cov khoom siv multimeter yuav qhia 1 lossis OL (qhib Circuit Court), qhia tias tsis muaj kev txuas ntxiv thiab luv luv hauv lub cuab yeej lossis Circuit Court raug ntsuas.
- Continuity Mode - Lub multimeter qhia xoom lossis ze rau xoom thiab beeps los qhia qhov txuas ntxiv. Txawm li cas los xij, tsis muaj qhov txuas ntxiv yog tias lub multimeter nyeem 1 lossis OL (qhib voj) thiab tsis beep. Tsis muaj kev txuas ntxiv qhia tau hais tias luv luv hauv lub cuab yeej hauv kev sim.
Cov lus qhia siv DMM los nrhiav qhov luv luv
Lub multimeter tuaj yeem siv los kuaj xyuas luv luv thiab cov yam ntxwv ntawm koj lub voj voog raws li nws tuaj yeem ua haujlwm raws li voltmeter, ohmmeter thiab ammeter.
Xaiv lub cuab yeej zoo
Txhawm rau txheeb xyuas qhov luv luv hauv Circuit Court, xyuas kom tseeb tias koj siv hom multimeter tsim nyog. Thaum tag nrho cov multimeters tuaj yeem ntsuas qhov tam sim no, qhov hluav taws xob, thiab qhov tsis kam, siab dua-kawg multimeters tuaj yeem ua ntau yam haujlwm. Rau ntau yam multimeter, nws yuav muaj kev nyeem ntawv ntxiv, txuas, thiab hom.
Tshawb xyuas cov yam ntxwv thiab cov ntsiab lus
Cov zaub loj, xaiv pob qhov rooj, cov chaw nres nkoj thiab kev sojntsuam yog cov khoom tseem ceeb ntawm koj lub multimeter. Txawm li cas los xij, yav dhau los analog multimeters suav nrog lub xov tooj thiab koob es tsis txhob siv cov duab digital. Muaj peev xwm muaj txog li plaub qhov chaw nres nkoj, ib nrab ntawm lawv yog liab thiab ib nrab yog dub. Qhov chaw nres nkoj dub yog rau COM chaw nres nkoj thiab lwm qhov peb yog rau kev nyeem ntawv thiab ntsuas.
Paub koj lub cuab yeej cov chaw nres nkoj
Thaum lub chaw nres nkoj dub siv rau kev sib txuas COM, lwm qhov chaw nres nkoj liab ua haujlwm sib txawv. Cov chaw nres nkoj hauv qab no suav nrog:
- VΩ yog ib chav ntsuas rau kev tiv thaiv, qhov hluav taws xob, thiab kev ntsuas txuas ntxiv.
- µAmA yog ib chav ntsuas rau qhov tam sim no hauv Circuit Court.
- 10A - siv los ntsuas tam sim no ntawm 200 mA thiab siab dua.
Cov npe hauv qab no yog lwm cov lus qhia thiab cov khoom qhia uas koj tuaj yeem tshawb xyuas;
- Yuav ua li cas kuaj lub Circuit Court breaker nrog multimeter
- Yuav ua li cas los txiav txim qhov nruab nrab hlau nrog ib tug multimeter
- Qhov zoo tshaj plaws multimeter
