Siv ib lub multimeter txhawm rau txheeb xyuas cov kab hluav taws xob tsis raug thiab nrhiav cov khoom tsis raug
Capacitance nrhiav pom
Kauj Ruam 1: Teem lub multimeter mus rau qhov muaj peev xwm thiab xaiv qhov tsim nyog
Kauj Ruam 2: Muab cov khoom ntsuas ntsuas ntsuas ntawm ob qho kawg ntawm ob tus pins
Tom qab kuaj nrog lub multimeter, peb tuaj yeem pom meej tias qhov me me tau ntsuas los ntawm kev nyeem ntawv. Nyeem cov ntawv nyeem ntawm lub multimeter, thiab tom qab ntawd sib piv cov txiaj ntsig tiag uas tau cim rau ntawm lub peev xwm. Yog tias ob qhov tseem ceeb no nyob ze, nws qhia tau hais tias qhov capacitance yog qhov qub. Peb lub capacitance tau sau tias yog 10uf, thiab ntsuas tus nqi yog 13.8uf, uas tuaj yeem hais tau ze.
Nws yog pom tseeb tias qhov kev nyeem ntawv ntawm lub multimeter yog xoom ncaj qha, uas yog txaus los qhia tias lub capacitor ntawm lub nruas no tau hlawv tiag tiag. Yog tias koj xav kho nws, koj tuaj yeem hloov nws nrog lub capacitor nrog tib qhov tsis muaj.
Diode nrhiav pom
Tom qab sib tham txog capacitance, cia peb txav mus rau qhov ntsuas diode. Txoj kev tshawb nrhiav diode yog ib qho yooj yim me ntsis tshaj li qhov kev kuaj pom lub peev xwm vim tias peb cov multimeter tuaj nrog lub diode nres thiab tsuas muaj ib txoj hauj lwm xwb, yog li peb tsis tas yuav xav txog qhov ntau. Peb muab nws tso rau ntawm lub diode nres thiab tom qab ntawd txuas tus ncej zoo ntawm lub multimeter mus rau lub anode ntawm lub diode, thaum tus ncej tsis zoo ntawm lub multimeter txuas nrog tus ncej zoo ntawm lub diode, Yog tias koj pom kev nyeem ntawv ntawm lub vijtsam multimeter. , nws qhia tau hais tias lub diode hauv Circuit Court yog ib txwm (qee lub multimeter yuav suab) thiab tsis tau tawg.
Kev kuaj xyuas inductance
Inductance yog ib qho tseem ceeb heev hauv lub xov tooj ntawm tes chargers, thiab yuav luag txhua lub charger tsis tuaj yeem ua yam tsis muaj nws. Yog li ntawd, nws yog ib qho tsim nyog rau peb kawm ib txoj hauv kev los ntsuas qhov inductance. "Inductance", uas peb kawm nyob rau hauv high school, yog sib npaug rau ib tug luv luv Circuit Court rau direct tam sim no. Peb tuaj yeem siv tau zoo ntawm qhov no thiab muab nws nrog lub diode thaiv ntawm lub tshuab multimeter.
Peb txhua tus paub tias yog lub diode thaiv liab thiab dub sojntsuam ncaj qha mus rau lub multimeter, nws yuav ua suab nrov, thiab yog tias nws tsis txuas nrog lub multimeter, nws yuav tsis ua suab. Ib yam li ntawd, yog tias nws txuas nrog lub inductor, nws yog tib yam. Sim nws, txhua leej txhua tus yuav tsum nco ntsoov tias ua ntej kev sib txuas, tshwj tsis yog lub buzzer, tsuas muaj ib lub cim diode nyob rau sab xis sab xis ntawm lub vijtsam multimeter.
