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.
Ntsuas qhov kev tiv thaiv pem hauv ntej ntawm lub diode.
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.
Ntsuas qhov rov qab tsis kam ntawm lub diode.
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.
