Yuav Ua Li Cas Siv Multimeter txhawm rau txheeb xyuas luv luv, qhib Circuit Court, thiab tam sim no leakage?
Nrhiav qhov luv luv
Lub voj voog luv luv yog hais txog qhov qis -impedance kev sib txuas ntawm ob lub ntsiab lus Circuit Court uas muaj peev xwm sib txawv. Txhawm rau txheeb xyuas qhov luv luv, koj yuav tsum ua raws li cov kauj ruam hauv qab no:
1. Disconnect lub Circuit Court: Ua ntej, disconnect lub Circuit Court nyob rau hauv kev sim thiab xyuas kom meej tias lub hwj chim mov yog muab tua. Qhov no yog ib kauj ruam tseem ceeb los xyuas kom muaj kev nyab xeeb.
2. Teem hom kev ntsuas: Teem lub multimeter rau DC kuj ntsuas hom. Rau ib qho digital multimeter, xaiv qhov tsim nyog; Rau ib qho analog multimeter, xaiv qhov chaw qis tshaj plaws.
3. Kev ntsuas kev sib txuas: Txuas ob txoj hauv kev ntawm multimeter mus rau ob lub ntsiab lus sib txawv ntawm lub voj voog nyob rau hauv kev sim. Yog hais tias lub multimeter qhia infinite kuj (piv txwv li, infinite resistance), nws qhia tias tsis muaj luv luv Circuit Court. Yog hais tias lub multimeter qhia tus nqi tsis kam ze rau xoom, nws tuaj yeem txiav txim siab tias muaj qhov luv luv.
4. Narrowing down the Scope: Yog tias kuaj pom qhov luv luv, koj yuav tsum rov qab tshem tawm qhov chaw ntawm lub voj voog kom paub meej qhov chaw ntawm qhov luv. Koj tuaj yeem ua qhov no los ntawm kev txiav cov khoom siv lossis cov xov hlau hauv Circuit Court ib los ntawm ib qho thiab rov ua cov kauj ruam 3, maj mam txo qis ntawm qhov chaw luv luv. Thov xyuas kom meej tias tom qab txiav tawm txhua qhov kev sib txuas hauv Circuit Court, koj txiav lub voj voog nyob rau hauv kev sim thiab tos rau lub sijhawm kom paub meej tias cov nqi hauv Circuit Court tau depleted.
5. Kev ceev faj: Thaum ua qhov ntsuas hluav taws xob luv luv, xyuas kom meej tias cov khoom siv hluav taws xob raug kaw thiab tag nrho cov kev ntsuas kev nyab xeeb rau lub ntsuas tau raug coj los ua. Tsis tas li ntawd, ceev faj tsis txhob kov qhov siab - qhov hluav taws xob thaum lub sijhawm ntsuas - lub sijhawm ntsuas kom tsis txhob muaj kev pheej hmoo ntawm hluav taws xob poob
Tshawb xyuas qhov qhib Circuit Court
Ib qho qhib Circuit Court yog hais txog kev cuam tshuam ntawm kev sib txuas hauv ib lub voj voog, tiv thaiv qhov ntws ntawm qhov tam sim no. Txhawm rau txheeb xyuas qhov qhib Circuit Court, koj tuaj yeem ua raws li cov kauj ruam hauv qab no:
1. Disconnect lub Circuit Court: Ua ntej, disconnect lub Circuit Court nyob rau hauv kev sim thiab xyuas kom meej tias lub hwj chim mov yog muab tua.
2. Teem lub ntsuas ntsuas: Teem lub multimeter mus rau qhov tsim nyog tam sim no lossis voltage ntsuas hom raws li hom Circuit Court yuav ntsuas. Rau cov multimeters digital, xaiv qhov tsim nyog; rau analog multimeters, xaiv qhov chaw siab tshaj plaws.
3. Kev ntsuas kev sib txuas: Txuas ib qho txhuas ntawm multimeter mus rau qhov taw tes ntawm lub voj voog ntawm lub voj voog nyob rau hauv kev sim, thiab txuas rau lwm tus ua rau qhov kev xav tau ntawm lub zog ntawm lub voj voog. Yog hais tias lub multimeter qhia ib tug tam sim no los yog voltage tus nqi ze rau xoom, nws qhia tau hais tias ib tug qhib Circuit Court.
4. Narrowing down the Scope: Yog tias pom muaj qhov tawg, koj yuav tsum rov qab tshem tawm qhov chaw ntawm lub voj voog kom pom qhov tawg tshwj xeeb. Koj tuaj yeem siv daim duab kos duab kos duab thiab tshuaj xyuas cov khoom lossis cov xaim hauv Circuit Court ib los ntawm ib qho, rov ua cov kauj ruam 3 kom maj mam nqaim qhov chaw ntawm qhov tawg. Nco ntsoov tshem tawm lub Circuit Court nyob rau hauv kev sim tom qab disconnecting txhua Circuit Court tivthaiv, thiab tos ib pliag kom ntseeg tau tias cov nqi nyob rau hauv Circuit Court tau depleted.
5. Kev ceev faj: Thaum kuaj xyuas qhov hluav taws xob tawg, xyuas kom meej tias cov khoom siv hluav taws xob tau raug muab tua thiab kev ntsuas kev nyab xeeb rau lub ntsuas tau raug siv. Tsis tas li ntawd, ua tib zoo ceev faj thaum qhib lossis tawm lub hwj chim. Rau siab -voltage circuits, yuav tsum muaj kev tiv thaiv tsim nyog.
Tshawb xyuas cov hluav taws xob xau
Kev xa hluav taws xob yog hais txog qhov xwm txheej uas tam sim no tsis tuaj yeem rov qab mus rau nws txoj kev qub hauv ib lub voj voog, uas ua rau cov dej ntws mus rau hauv av lossis lwm yam kev txawv txav. Txhawm rau kuaj xyuas hluav taws xob, koj tuaj yeem ua raws li cov kauj ruam hauv qab no:
1. Npaj lub voj voog: Rov txuas lub voj voog nyob rau hauv kev sim rau lub hwj huam mov thiab xyuas kom meej tias tag nrho cov khoom tsis yog -tseem ceeb raug muab tua kom txo tau qhov yuam kev.
2. Teem hom kev ntsuas: Teem lub multimeter rau AC tam sim no ntsuas hom. Xaiv qhov chaw tsim nyog.
3. Kev ntsuas tam sim no: Ua ntej, txuas ib qho ntawm cov khoom siv multimeter mus rau theem kab ntawm lub zog hluav taws xob (feem ntau yog cov xaim nyob) thiab txuas rau lwm cov hlau lead mus rau qhov chaw hauv av lossis qhov xav tau rov qab taw tes ntawm lub voj voog. Nyeem cov nqi tam sim no tso tawm ntawm lub multimeter. Yog tias tsis yog - xoom tam sim no tus nqi raug kuaj pom, nws qhia tias muaj cov dej xau.
4. Kev ua kom qis qis: Yog tias pom muaj cov dej xau, koj yuav tsum rov qab tshem tawm qhov chaw ntawm lub voj voog txhawm rau txheeb xyuas qhov chaw xau tshwj xeeb. Koj tuaj yeem siv daim duab kos duab hauv Circuit Court thiab tshuaj xyuas cov khoom lossis cov xaim hauv Circuit Court ib los ntawm ib qho, rov ua cov kauj ruam 3 kom maj mam txo qis ntawm qhov chaw xau. Xyuas kom meej tias lub Circuit Court nyob rau hauv kev ntsuam xyuas yog disconnected tom qab txhua lub Circuit Court yog disconnected, thiab tos rau ib lub sij hawm ntawm lub sij hawm kom paub tseeb tias cov nqi nyob rau hauv Circuit Court tau depleted.
5. Kev ceev faj: Thaum kuaj xyuas cov dej xau, xyuas kom meej tias cov khoom siv hluav taws xob raug kaw thiab kev ntsuas kev nyab xeeb rau lub ntsuas tau raug siv. Tsis tas li ntawd, ua tib zoo ceev faj thaum qhib lossis tawm lub hwj chim. Rau siab -voltage circuits, yuav tsum muaj kev tiv thaiv tsim nyog.
