Yuav ua li cas siv cov tshuaj mullamatal coures seb puas yog Circuit Court yog hluav taws xob
Lub Tawv Circuit Court breaker yog teem rau ib qho kev nyab xeeb tripping txiaj ntsig txog 30mA. Nrog xws li qhov siab tam sim no, txawm tias koj siv AC hom kev sib sau ua ke lossis lub hom resisteter yooj yim lossis koj tuaj yeem yooj yim pom cov dej xau.
Thaum them, xub siv cov ntsuas ntsuas digital digital rau ntsuas cov xaim sab nraud ntawm cov hlau. Yog tias tsuas yog "n" yog tso tawm, nws yog qhov qub. Yog tias cov ntaub ntawv tso tawm pom muaj qee qhov voltage, nws qhia cov hlau tsis zoo lossis kev laus. Muaj peev xwm ntawm hluav taws xob tougically.
Tig rau ntawm ntau multatateter rau ace 250V thiab ntsuas qhov hluav taws xob ntawm 220V {2}} xoom} xoom rau hluav taws thiab hauv av. Saib seb lub zog siv hluav taws xob ntau npaum li cas, thiab ib qho hluav taws xob ntawm 5V mus rau ob peb kaum ntawm volts yuav ntsuas tau. Nov yog Circuit Court impedance tshwm sim los ntawm txoj kab uas hla me me ntawm nruab nrab xaim, uas ua rau qhov nruab nrab xaim nyob. Yog tias xoom av cov zaub ua yeeb yam qhia txog kev ntsuas hluav taws xob siab, nws qhia tau tias xoom lub taub hau, thiab nws tsis haum rau lub zog ntawm cov khoom siv hauv tsev. Muaj zog cov khoom siv hauv tsev yuav tsum tau siv nyob rau lub sijhawm sib txawv.
Tua lub ntsiab hloov thiab disconnect lub hloov pauv, tsis tau siv Ohm 10k ntau yam los kuaj xyuas yog tias tsis tig mus, uas yog suav tias yog ib txwm
Yog hais tias lub cub hluav taws tsis txav mus thaum rov qab ua dua, nws suav hais tias yog qhov qub
Thaum kawg, yog tias lub voj voog pob zeb pointer tsis txav, nws suav hais tias yog qhov qub
Yog hais tias cov kev ntsuas saum toj no qhia kev txav me me ntawm tus pointer, nws qhia tau tias muaj towakage. Qhov tshwm sim no yog tshwm sim los ntawm kev xau dej hauv chav ua noj thiab chav dej, ua rau muaj cov pob qij txha me thaum raug cov av noo. Thaum kuaj xyuas cov Circuit Court, xub thawj tua lub chav ua noj thiab chav dej Circuit Court Furner thiab ntsuas kev ntsuas seb puas muaj to.
Yuav tsum tau siv nruj me ntsis, tus melohmeter yuav tsum tau siv los ua kev ntsuas yog hlau to, tab sis rau kev xau nyob rau hauv 30k ntau yuav ntsuas nws. Yog tias cov digital motimeter yog siv, nws yuav rhiab dua.
