Yuav ua li cas siv tus multimeter los kuaj xyuas circuits
Lub motatal anlotive hom kev muag khoom, uas txhais tau tias siv ob txoj kev sim ntsuas tib lub xaim. Yog tias muaj lub luv luv ntawm Circuit Court, yuav tsis muaj lus teb. Yog tias muaj Circuit Court, yuav muaj lub suab nrov nrov. Qee zaum, thaum lub ntaus ntawv nws tus kheej tsis zoo nyob rau hauv lub plhaub thiab daim paib liab tuaj yeem tso rau hauv av los ntsuas lub zog ntawm lub plhaub xau tam sim no. Hauv kev ua haujlwm uas tshuav, nws kuj tuaj yeem txuas tau rau hauv cov Circuit Court ntsuas AC thiab DC.
Txheeb xyuas cov hluav taws xob xau hauv Circuit Court, ib meGOhmermeter (Shaker) yuav tsum tau siv vim tias hluav taws xob multadage yog qis dua (9V) thiab MorgehmMeter voltage yog siab dua (500v). Raws li kev ua haujlwm voltage ntawm Circuit Court yog 220v, nws yog qhov nyuaj rau kev kuaj pom cov kab ke nrog tsis meej cov hluav taws xob tsis meej. Txhawm rau tshuaj xyuas cov xau ntawm lub voj voog nrog lub ntsuas kub digital, cov khoom siv hluav taws xob yuav tsum tau txiav ua ntej. Tom qab rho tawm ntawm Circuit Court, ntsuas nws nrog hom tsis kam thiab 2m hom. Cov zaub ib txwm yog 1 (infinite).
Ntsuas seb puas yog Circuit Court yog nyob rau hauv lub xeev sib txuas los ntawm kev siv ntau ntau hauv OHM ntau. Thaum ntsuas ntsuas, xaiv cov ntau qhov chaw uas 'meter tus pointer yog ze rau deflection ntawm 0 ohms. Yog tias lub Circuit Court yog nyob rau hauv Circuit Court, txuas ib qho kawg (qhov kawg ntawm lub Circuitalim rau 100 Ohm ntau yam ntawm kev sojntsuam dub mus rau lwm qhov kawg (b kawg) ntawm Circuit Court raug ntsuas. Yog tias ntsuas cov txiaj ntsig yog xoom, nws txhais tau tias lub Circuit Court tau txuas nrog, tseem hu ua txoj kev. Tsuas yog ib txoj kev tso cai rau tam sim no dhau los ntawm Circuit Court; Yog hais tias rultimeter Ohm khwv tau ntau zaus pointer ntawm a to b kawg ntawm cov kab tsis yog hu ua lub xeev qhib lossis qhib Circuit Court lossis qhib Circuit Court lossis qhib Circuit Court.
