Txoj kev ntsuas qhov zoo ntawm rectifier diode nrog pointer multimeter

Pointer multimeter los xyuas seb lub rectifier diode puas zoo lossis phem
Diodes muaj unidirectional conductivity. Ntawd yog, qhov hluav taws xob rau pem hauv ntej yog siv rau kev coj ua, thiab qhov hluav taws xob rov qab yog siv los txiav tawm. Nws cov kev tiv thaiv pem hauv ntej yog me me thiab rov qab tsis kam yog loj, uas yog lub hauv paus rau kev tshawb nrhiav.
1. Raws li ib txwm muaj, rau ib lub diode rectifier, ua ntej tso lub multimeter hauv Rx100 lossis Rx1K ntau ntawm ohm ntau yam thaum kuaj. Txuas ob qhov kev xeem coj mus rau ob lub taub hau ntawm lub diode los ntsuas qhov ntsuas qhov 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. Yog tias qhov kev tiv thaiv me me, cov hlau lead kuaj dub txuas nrog tus ncej zoo ntawm lub diode, thiab cov hlau kuaj liab txuas nrog rau qhov tsis zoo ntawm lub diode.
Yog tias ob qhov kev tiv thaiv qhov tseem ceeb loj, nws txhais tau hais tias lub diode qhib Circuit Court.
Yog tias ob qhov kev tiv thaiv qhov tseem ceeb tsawg heev, nws txhais tau hais tias lub diode luv luv Circuit Court.
Nws yuav tsum raug sau tseg tias qhov ntsuas qhov ntsuas qhov ntsuas yuav txawv thaum xaiv cov iav sib txawv.
2. Thaum lub sij hawm tu, feem ntau yuav tsum tau solder lub diode los ntawm Circuit Court, uas yog teeb meem. Qhov tseeb, nws kuj tseem tuaj yeem tshawb xyuas 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 qhia rau siv.
Fais fab ntawm cov khoom siv hluav taws xob ib txwm muaj (hloov tam sim no), tig lub multimeter mus rau AC voltage ntau, xaiv cov iav tshwj xeeb raws li qhov ntsuas qhov ntsuas hluav taws xob ntau, txuas cov kev ntsuas liab coj mus rau tus ncej zoo ntawm lub rectifier diode, thiab cov hlau kuaj dub mus rau tus ncej tsis zoo los ntsuas tus nqi AC voltage. Tom qab ntawd thim rov qab qhov kev xeem coj, thiab ntsuas tus nqi hluav taws xob. Nyob rau hauv tib txoj kev, teeb qhov ntau ntawm cov multimeter mus 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 diode rectifier yog qhov qub.
Yog tias ob qhov ntsuas AC voltage qhov tseem ceeb tsis txawv ntau, nws txhais tau hais tias lub diode tau tawg lawm.
Yog hais tias tus nqi voltage ntsuas ob zaug yog xoom, nws txhais tau hais tias lub diode tau luv luv-circuited.
Yog tias tus nqi ntsuas rau lub sijhawm thib ob tsis yog xoom lossis sib npaug ntawm tus nqi ntawm thawj zaug, nws txhais tau tias qhov kev ua haujlwm ntawm diode tau deteriorated.
