Raws li tus kws tshaj lij hluav taws xob lossis ib tus neeg ua haujlwm nrog cov khoom siv hluav taws xob, nws yog ib qho tseem ceeb kom muaj cov cuab yeej zoo ntawm tes. Ib qho ntawm cov cuab yeej tseem ceeb uas yuav tsum muaj nyob rau hauv koj cov khoom siv yog multimeter, ib qho cuab yeej uas tuaj yeem pab koj kuaj amperage thiab voltage. Txawm li cas los xij, yog tias koj tsis paub yuav ua li cas siv lub multimeter, kev ntsuas yuav yog ib txoj haujlwm txaus ntshai. Hauv tsab xov xwm no, peb yuav piav qhia yuav ua li cas kuaj amperage thiab voltage siv lub multimeter.
Ua ntej peb delve rau hauv cov kauj ruam hauv kev kuaj xyuas amperage thiab voltage, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias koj yuav tsum tsis txhob sim lub voj voog nyob tshwj tsis yog tias koj paub tseeb tias koj tuaj yeem ua tau yam xyuam xim. Nco ntsoov hloov hluav taws xob ua ntej kuaj thiab siv PPE tsim nyog (cov cuab yeej tiv thaiv tus kheej).
Yuav Ua Li Cas Ntsuas Voltage nrog Multimeter
Ib qho ntawm cov kev siv yooj yim tshaj plaws ntawm multimeter yog los xyuas qhov voltage. Nov yog yuav ua li cas:
Kauj Ruam 1: Teem lub multimeter rau qhov teeb tsa voltage
Qhov no feem ntau yog qhia los ntawm lub cim "V" lossis "DCV" rau qhov hluav taws xob ncaj qha tam sim no. Nyob ntawm koj lub multimeter, koj tuaj yeem muaj lwm yam kev xaiv xws li AC voltage lossis millivolts.
Kauj ruam 2: Txuas lub Multimeter
Txhawm rau ntsuas qhov ntsuas hluav taws xob, koj yuav tsum txuas lub multimeter coj mus rau lub voj voog. Txuas cov hlau lead liab mus rau sab zoo ntawm lub voj voog lossis cov khoom siv thiab cov hlau lead dub mus rau sab tsis zoo. Xyuas kom cov kev sib txuas ruaj ntseg.
Kauj Ruam 3: Siv qhov ntsuas
Thaum cov kev sib txuas muaj kev ruaj ntseg, koj tuaj yeem qhib lub zog thiab ntsuas qhov ntsuas.
Thaum kuaj qhov hluav taws xob, nws yog ib qho tseem ceeb los txheeb xyuas qhov xav tau voltage ua ntej. Qhov no tuaj yeem ua tiav los ntawm kev siv schematic lossis daim ntawv ntsuas hluav taws xob. Yog tias qhov hluav taws xob siab dhau los yog qis dhau, koj yuav tsum tau teeb meem hauv Circuit Court.
Yuav Ua Li Cas Xyuas Amperage nrog Multimeter
Kev kuaj amperage yog qhov nyuaj me ntsis dua li kuaj xyuas qhov voltage. Nov yog yuav ua li cas:
Kauj ruam 1: Teem lub Multimeter rau Amperage Setting
Txhawm rau kuaj amperage, teeb lub multimeter mus rau qhov chaw amperage. Qhov no feem ntau yog qhia los ntawm lub cim "A". Xyuas kom meej tias qhov ntau yam xaiv tau txaus rau qhov amperage raug kuaj. Yog tias tsis paub meej, xaiv qhov ntau tshaj plaws.
Kauj ruam 2: Txuas lub Multimeter
Txhawm rau ntsuas amperage, koj yuav tsum tau txuas lub multimeter hauv series nrog lub voj voog. Qhov no txhais tau hais tias koj yuav tsum tau ua txhaum lub voj voog thiab txuas cov hlau lead dub mus rau qhov tsis zoo ntawm lub hwj chim, thiab cov hlau lead liab rau cov khoom siv los yog cov khoom raug ntsuas.
Kauj Ruam 3: Kaw lub Circuit Court thiab ntsuas ntsuas
Thaum lub multimeter txuas nrog, koj tuaj yeem kaw lub voj voog thiab ntsuas qhov ntsuas. Nyob ntawm qhov ntsuas amperage, koj yuav tsum tau tos ob peb feeb ua ntej nyeem ntawv.
Hauv kev xaus, siv multimeter los ntsuas amperage thiab voltage yog txheej txheem yooj yim thaum koj muaj kev paub thiab nkag siab txog nws ua haujlwm li cas. Nco ntsoov ua txhua yam khoom siv hluav taws xob nrog kev saib xyuas zoo tshaj plaws thiab ceev faj vim tias lawv tuaj yeem ua rau muaj kev phom sij yog tias ua tsis raug.
