Yuav ua li cas kuaj qhov zoo ntawm rectifier diodes nrog analog multimeter
Rectifier diodes feem ntau yog siv nyob rau hauv rectifier circuits los hloov alternating tam sim no rau hauv ncaj qha tam sim no los ntawm kev siv lub unidirectional xwm ntawm lub diode. Cov ntaub ntawv rectification muaj xws li ib nrab-wave rectification thiab puv-yoj rectification.
Rectifier diodes kuj tuaj yeem ua tsis tiav, uas tuaj yeem tshwm sim raws li diode luv Circuit Court, qhib Circuit Court, thiab lwm yam.
Koj tuaj yeem siv lub pointer multimeter lossis digital multimeter los kuaj xyuas qhov zoo ntawm diode. Cia peb tham txog kev siv lub ntsuas ntsuas ntsuas los ntsuas thiab txiav txim qhov zoo ntawm rectifier diodes.
Pointer multimeter pom qhov zoo ntawm rectifier diodes
Diodes ua hluav taws xob hauv ib qho kev taw qhia. Ntawd yog, thov rau pem hauv ntej voltage tig nws thiab thov rov qab voltage tig nws tawm. Nws qhov kev tiv thaiv pem hauv ntej yog me me thiab nws qhov rov qab tsis kam yog loj, uas yog lub hauv paus rau kev tshawb nrhiav.
Nquag, rau ib qho rectifier diode, thawj zaug teeb lub multimeter rau Rx100 lossis Rx1K ohm ntau yam thaum kuaj. Txuas ob qhov kev xeem coj mus rau ob lub taub hau ntawm lub diode thiab ntsuas tus nqi tsis kam. Tom qab ntawd pauv ob qhov kev xeem coj mus kuaj thiab ntsuas tus nqi tiv thaiv dua. Thaum kawg, sib piv cov txiaj ntsig ntawm ob qhov kev ntsuas.
Yog tias thawj qhov kev tawm tsam loj thiab thawj qhov kev tawm tsam me me, nws txhais tau hais tias lub rectifier diode yog qhov qub. Thaum qhov kev tiv thaiv me me, cov hlau kuaj dub txuas nrog lub anode ntawm diode, thiab cov hlau kuaj liab txuas nrog lub cathode ntawm diode.
Yog tias qhov kev tiv thaiv siab heev ob zaug, nws txhais tau hais tias lub diode qhib.
Yog tias qhov kev tiv thaiv tsawg heev ob zaug, nws txhais tau hais tias lub diode yog luv luv.
Nws yuav tsum raug sau tseg tias qhov ntsuas ntsuas qhov ntsuas yuav txawv yog tias xaiv cov iav sib txawv.
Thaum lub sij hawm tu, lub diode feem ntau yuav tsum tau soldered tawm ntawm Circuit Court, uas yog teeb meem. Qhov tseeb, koj tuaj yeem ntes nws ncaj qha hauv online yam tsis tas siv lub tshuab rectifier diode. Txoj kev yog yooj yim thiab cov nyhuv yog zoo. Tam sim no kuv qhia rau siv.
Fais fab ntawm cov khoom siv hluav taws xob ib txwm muaj (AC), teeb lub multimeter mus rau AC voltage ntau, xaiv ib qho tshwj xeeb raws li cov khoom siv hluav taws xob rectifier, txuas cov kev ntsuam xyuas liab coj mus rau tus ncej zoo ntawm lub rectifier diode, thiab qhov kev sim dub ua rau tus ncej tsis zoo, thiab ntsuas tus nqi AC voltage. Tom qab ntawd thim rov qab qhov kev xeem coj thiab ntsuas lwm tus nqi hluav taws xob. Siv tib txoj kev, teeb lub multimeter's range rau DC voltage ntau thiab ntsuas tus nqi DC voltage. Tom qab ntawd sib piv cov txiaj ntsig.
Yog tias tus nqi AC voltage ntsuas thawj zaug yog kwv yees li ob npaug ntawm DC voltage tus nqi, thiab AC voltage ntsuas rau lub sijhawm thib ob yog xoom, nws txhais tau hais tias lub rectifier diode yog qhov qub.
Yog tias qhov ntsuas AC voltage ntsuas ob zaug tsis txawv ntau, nws txhais tau hais tias lub diode tau tawg.
Yog hais tias tus nqi voltage ntsuas ob zaug yog xoom, nws txhais tau hais tias lub diode yog luv luv.
Yog tias tus nqi ntsuas thib ob tsis yog xoom lossis sib npaug ntawm tus nqi ntawm thawj zaug, nws txhais tau tias qhov kev ua tau zoo ntawm diode tau deteriorated.
