Taw qhia rau txoj kev ntsuas Circuit Court luv luv, qhib Circuit Court thiab to nrog multimeter
1. Ntsuas luv Circuit Court nrog multimeter
Txoj kev ua haujlwm:
Ntxig cov xim dub ntawm cov khoom siv multimeter rau hauv "com" qhov, ntxig cov hlau kuaj liab rau hauv "VΩ" qhov, thiab tig lub pob qhov rooj mus rau qhov chaw buzzer.
Tshem tawm cov khoom siv hluav taws xob ntawm cov kab sim, thiab sim ob kab ntawm kab nrog ob txoj kev xeem. Yog tias qhov tsis kam ntawm multimeter qhia tau tias 0 thiab muaj lub suab nrov, nws txhais tau hais tias muaj ib qho luv luv hauv kab.
Los yog siv cov ntaub ntawv ohm 1k lossis 10k cov ntaub ntawv, txiav tawm lwm qhov kawg ntawm kab, thiab sim ob kab nrog ob txoj kev xeem. Yog hais tias qhov tsis kam ntawm multimeter qhia 0, nws txhais tau hais tias muaj luv luv Circuit Court nyob rau hauv kab.
2. Multimeter los ntsuas qhov qhib Circuit Court
Txoj kev ua haujlwm:
Thaum kuaj cov kab txuas txuas ntxiv, nco ntsoov txiav lub hwj chim ua ntej kuaj.
Tig lub pob qhov rooj mus rau txoj hauj lwm buzzer, thiab kuaj xyuas tias ob qhov kawg ntawm kab yog nyob rau hauv kev sib cuag nrog cov koob hlau ntawm tus cwj mem xeem. Yog tias muaj qee yam tsis kam thiab muaj lub suab nrov, nws txhais tau hais tias txoj kab txuas nrog; yog tias qhov kev tiv thaiv tsis muaj qhov kawg, nws yuav tshwm sim raws li 1. Thiab tsis muaj lub suab nrov, txoj kab raug txiav.
Los yog xaiv qhov 10k ntau yam ntawm multimeter, luv rau lwm qhov kawg ntawm kab, thiab sim ob kab nrog cov kev xeem coj ntawm multimeter. Yog hais tias qhov tsis kam ntawm multimeter qhia 1, nws txhais tau hais tias qhib Circuit Court; yog tias nws qhia 0, kab yuav txuas nrog.
3. Multimeter los ntsuas qhov to
Muaj cov xau hauv kab, feem ntau tsis pom zoo kom siv multimeter los kuaj, yog tias tsis muaj lwm yam ntsuas, nws kuj tseem tuaj yeem siv multimeter.
Txoj kev ua haujlwm:
Tig lub multimeter mus rau AC voltage txoj hauj lwm, ntsuas nrog hluav taws xob, thiab ntsuas cov hlau casing ntawm cov cuab yeej xav tias yuav to.
Thaum ntsuas, ib qho kev xeem txhuas txuas nrog lub plhaub, thiab lwm qhov kev xeem cov hlau lead yog hauv av. Yog tias qhov tso tawm voltage siab dua 30V, sim dua. Yog tias cov khoom siv hluav taws xob tau lees paub tias siab dua 30V, nws txhais tau hais tias muaj cov xau. Feem ntau, nws yog qhov qub yog tias nws qis dua 30V. Koj tseem tuaj yeem txuas cov kab nruab nrab, Tom qab thim rov qab ntawm lub ntsuas hluav taws xob nyob, nws tuaj yeem lees paub los ntawm kev ntsuas ib zaug.
