Txoj kev ntsuas diode nrog cov ntaub ntawv multimeter diode
Siv lub diode iav ntawm cov digital multimeter los ntsuas qhov pem hauv ntej thiab thim rov qab tsis kam (voltage poob) ntawm diode kom txiav txim siab qhov zoo ntawm ntau yam diodes. Txoj kev ntsuas tshwj xeeb yog qhia hauv qab no.
Thaum ntsuas qhov zoo ntawm lub diode, ua ntej kho qhov hloov pauv ntawm digital multimeter mus rau diode txoj hauj lwm, thiab tom qab ntawd kov cov ncej zoo thiab tsis zoo ntawm lub diode nrog cov xim liab thiab dub coj mus kuaj (feem ntau, tus pin nrog lub nplhaib xim ntawm lub diode. diode plhaub yog tus ncej tsis zoo). Rau qhov zoo silicon diodes, cov kev nyeem tau pom los ntawm multimeter yog feem ntau nyob rau hauv qhov ntau ntawm {{0}}.500 mus rau 0.700 (qhov loj me muaj feem xyuam rau hom diode thiab kev xeem tam sim no ntawm multimeter); rau qhov zoo Schottky diodes thiab germanium diodes, cov kev nyeem pom los ntawm multimeter feem ntau yog nyob rau hauv 0.150-0.300. Daim duab saum toj no qhia tau hais tias cov kev nyeem tau nthuav tawm los ntawm multimeter ntsuas qhov zoo silicon rectifier diode.
Thaum ntsuas qhov kev tiv thaiv pem hauv ntej ntawm lub diode, yog tias qhov kev nyeem pom los ntawm multimeter yog "0.00" lossis "OL (overflow)", nws txhais tau tias lub diode puas lawm.
Tom qab ntsuas qhov kev tiv thaiv pem hauv ntej ntawm lub diode, sib pauv cov xim liab thiab xim dub, kov cov electrode tsis zoo ntawm diode nrog cov hlau kuaj liab, thiab kov cov electrode zoo ntawm diode nrog cov xim dub kuaj, raws li qhia hauv daim duab saum toj no . Nyob rau lub sijhawm no, rau cov diodes zoo, cov kev nyeem tau pom los ntawm multimeter feem ntau yog "OL".
Thaum ntsuas lub pem hauv ntej thiab thim rov qab tsis kam ntawm diode nrog multimeter, yog tias cov ntawv nyeem rau pem hauv ntej thiab rov qab pom los ntawm ib qho diode yog ob qho tib si "0.00" lossis "OL", nws txhais tau hais tias lub diode. puas lawm.
Yuav ua li cas ntsuas voltage nrog multimeter? Yuav ua li cas ntsuas voltage nrog multimeter
Txoj kev ntsuas hluav taws xob yog qhov yooj yim dua thiab muaj kev nyab xeeb dua li txoj kev tam sim no, vim tias qhov qub Circuit Court tsis tas yuav tsum tau hloov pauv thaum ntsuas kev tiv thaiv, tsuas yog txuas tus cwj mem multimeter rau ob qho kawg ntawm cov khoom hauv qab kev sim. Yuav tsis muaj luv luv Circuit Court, qhov tam sim no ntau yam txawv, thiab sab hauv kuj yuav luag xoom. Yog tias qhov kev sib txuas tsis raug, cov khoom seem yuav raug hlawv.
Txiav txim siab hom khoom siv hluav taws xob raws li kev sim
Ua ntej ntsuas qhov hluav taws xob ntawm ob qho kawg ntawm cov khoom, ua ntej txiav txim siab hom hluav taws xob, seb nws yog AC voltage lossis DC voltage. Lub multimeter rau AC thiab DC tsis nyob hauv tib lub iav, yog li txiav txim siab hom ua ntej ntsuas. Siv DC iav rau DC thiab siv AC iav rau AC. me ntsis.
Tom qab txiav txim, xaiv qhov tsim nyog. Yog tias koj tsis paub qhov voltage yuav tsum ntsuas, koj tuaj yeem xaiv qhov loj tshaj plaws thiab hloov qhov ntau raws li qhov pom qhov voltage.
ntsuas voltage
Tom qab kev npaj ua haujlwm ntawm thawj ob kauj ruam ua tiav, tom qab ntawd koj tuaj yeem muab qhov kev xeem coj mus kuaj ntawm ob qho kawg ntawm lub zog hluav taws xob los kuaj. Yog tias qhov ntsuas tau raug, qhov voltage ntawm lub sijhawm no yuav raug muab tso rau ntawm qhov screen ntawm multimeter.
