Ntawm no yog cov lus piav qhia ntxaws txog kev siv lub multimeter los ntsuas qhov zoo thiab qhov tsis zoo ntawm lub diode.
1. Kuv tsis tuaj yeem pom meej cov qauv ntawm koj lub multimeter;
2. Rau cov digital multimeters zoo tib yam, qhov ntsuas hluav taws xob ntawm qhov teeb tsa diode tsawg dua 2V, thiab qhov koj ntsuas yog P6KE36, uas yog bidirectional diode. Rau hom diode no, qhov hluav taws xob ntawm qhov chaw diode ntawm multimeter yuav tsum yog tsawg kawg 6V ua ntej nws tuaj yeem ntsuas tau, thiab qhov dav dav Diode ntau ntawm digital multimeter tsis tuaj yeem ncav cuag qhov voltage no txhua;
3. Txhawm rau muab nws yooj yim, nws tsuas yog ua tau los ntsuas qhov diode thaum qhov hluav taws xob ntawm ob qhov kev sim ntawm diode ntau tshaj 6V, thiab koj lub multimeter tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua;
4. Txhawm rau siv koj lub multimeter los ntsuas qhov diode, koj yuav tsum siv lub tshuab hluav taws xob tswj hluav taws xob nrog qhov hluav taws xob ntau tshaj 10V, txuas lub resistor hauv series, thiab tom qab ntawd txuas rau hauv series nrog lub diode ntsuas seb nws puas zoo lossis phem;
5. Raws li kev tiv thaiv thiab lub zog ntawm cov resistor hauv series, nws yuav tsum tau txiav txim siab raws li qhov kev khiav hauj lwm tam sim no ntawm koj lub diode. Kuv tsis tuaj yeem muab ib qho kev suav tshwj xeeb rau koj ntawm no.
6. Vim tias qhov voltage ntawm diode ntau ntawm koj lub multimeter tsis ua raws li qhov yuav tsum tau ua, kev ntsuas rau pem hauv ntej thiab rov qab tsis zoo, tab sis qhov no tsis ua pov thawj tias bidirectional diode tawg.
7. Txhawm rau muab nws yooj yim, hom diode no tsis tuaj yeem ntsuas ncaj qha nrog lub diode teeb tsa ntawm multimeter.
Tus nqi ntsuas los ntawm diode thaiv ntawm digital multimeter ntawm lub rectifier diode yog dab tsi?
Siv hom diode ntawm lub tshuab multimeter, ntxig cov hlau kuaj liab rau hauv VΩ lub qhov thiab ntxig cov hlau kuaj dub rau hauv COM qhov. Peb paub tias nyob rau hauv lub multimeter digital, qhov kev ntsuam xyuas liab tau hu rau qhov zoo electrode ntawm lub roj teeb sab hauv, thiab qhov kev ntsuam xyuas dub ua rau cov hluav taws xob tsis zoo ntawm lub roj teeb sab hauv. Nyob rau hauv lub analog multimeter, hluav taws xob teeb meem yog hais tias cov liab xeem lead tiv tauj cov roj teeb sab hauv. Txuas qhov tsis zoo electrode ntawm lub roj teeb thiab qhov kev sim dub coj mus rau qhov zoo electrode ntawm lub roj teeb sab hauv. Kov cov liab xeem lead ntawm cov digital multimeter mus rau qhov zoo electrode ntawm lub diode thiab qhov kev ntsuam xyuas dub ua rau qhov tsis zoo electrode ntawm diode. (Kev ntsuas tus nqi pem hauv ntej tsis kam) Tus nqi ib txwm yog 300-600Ω. Tom qab ntawd kov qhov kev sim liab ua rau qhov tsis zoo electrode ntawm lub diode thiab qhov kev sim dub coj mus rau qhov zoo electrode ntawm diode. ( Ntsuas tus nqi rov qab los), tus nqi ib txwm yog "1". Yog tias ob qho kev ntsuas pom 001 lossis 000 thiab lub suab nrov, nws txhais tau tias lub diode tau tawg lawm. Yog tias qhov ntsuas qhov ntsuas rov qab thiab rov qab ntsuas ob zaug yog ob qho tib si "1" Nws txhais tau hais tias lub diode qhib Circuit Court. Yog tias ob qhov ntsuas qhov ntsuas zoo sib xws, nws txhais tau hais tias qhov zoo ntawm lub raj yog qhov tsis zoo. Tus nqi rov qab yuav tsum yog "1" lossis ntau dua 1000, thiab tus nqi rov qab yuav tsum yog 300-600Ω. Tom qab ntawd lub diode zoo.
