Txoj kev ntsuas DC tam sim no ntawm multimeter
1. Ntxig cov hlau lead dub rau hauv COM jack. Thaum ntsuas qhov siab tshaj plaws tam sim no ntawm 200mA, ntxig cov hlau lead liab rau hauv mA jack. Thaum ntsuas qhov siab tshaj plaws tam sim no ntawm 20A, ntxig cov hlau lead liab rau hauv 20A jack.
2. Muab qhov hloov pauv ua haujlwm hauv DC tam sim no ntau A - qhov tsim nyog.
3. Txuas cov kev sojntsuam kuaj hauv series mus rau qhov kev thauj khoom mus kuaj, tswj kev ruaj ntseg, thiab tom qab ntawd nyeem. Yog tias nws qhia tau tias "1", ces qhov ntau yuav tsum tau nce. Yog tias "-" tshwm rau sab laug ntawm tus nqi, nws qhia tau tias tam sim no ntws los ntawm kev sojntsuam dub mus rau hauv multimeter.
Cov lus qhia ua haujlwm
1. Xaiv lub DC tam sim no iav, thiab thaum lub sijhawm tam sim no tsis paub, pib los ntawm qhov siab tshaj plaws.
2. Ua tib zoo saib xyuas cov kev taw qhia ntawm qhov tam sim no, uas yog, cov hlau lead liab txuas nrog tus ncej zoo (lossis muaj peev xwm siab), thiab cov hlau lead dub txuas nrog rau cov ncej tsis zoo (lossis tsis muaj peev xwm) ntawm cov khoom siv hluav taws xob.
3. Lub 'meter' yuav tsum tau txuas nrog nyob rau hauv series nyob rau hauv lub Circuit Court ntawm lub ntsuas tam sim no.
4. Txoj kev ntsuas AC tam sim no zoo ib yam li ntsuas DC tam sim no, tab sis tsis muaj kev txwv polarity.
Kev ntsuas cov kauj ruam rau DC tam sim no
Kauj ruam 1: Tig lub multimeter mus rau 200mA DC tam sim no ntau yam.
Kauj Ruam 2: Kaw S1 ntawm lub cev hluav taws xob.
Kauj Ruam 3: Txuas cov hlau lead liab mus rau 1 thiab cov hlau lead dub rau 2, soj ntsuam kev nyeem ntawv, thiab ntsuas qhov tam sim no ntawm cov ntsiab lus 1 thiab 2 hauv ceg yog 20mA.
4, Kev ceev faj
1. Yog tias qhov ntsuas tam sim no tsis paub ua ntej siv, teeb tsa txoj haujlwm hloov mus rau qhov siab tshaj plaws thiab maj mam txo qis.
2. Yog tias cov zaub yog "1.", nws qhia tau hais tias qhov ntau me me dhau lawm thiab qhov kev ua haujlwm hloov yuav tsum tau teem rau ntau dua.
3. Qhov siab tshaj plaws input tam sim no yog 200mA. Tshaj tam sim no yuav hlawv tawm lub fuse thiab nws yuav tsum tau hloov. 20A ntau yam tsis muaj kev tiv thaiv fuse thiab tsis tuaj yeem tshaj 15 vib nas this thaum ntsuas.
4. Txoj kev ntsuas ntawm AC tam sim no yog tib yam li ntawm DC, tab sis lub iav yuav tsum tau teem rau AC iav A ~. Tom qab kev ntsuas tam sim no, tus cwj mem liab yuav tsum tau muab tso rau hauv qhov "V Ω" qhov. Yog tias koj tsis nco qab cov kauj ruam no thiab ntsuas qhov hluav taws xob ncaj qha, lub ntsuas hluav taws xob lossis lub zog hluav taws xob yuav raug muab pov tseg. Thov ua tib zoo ua haujlwm!
Yuav siv lub tshuab hluav taws xob digital li cas los ntsuas DC tam sim no _ Digital multimeter
Cov lus qhia rau kev ntsuas tam sim no siv lub multimeter
Qhov zoo tshaj plaws, qhov kev tiv thaiv sab hauv ntawm qhov tam sim no yuav tsum sib npaug rau xoom, tab sis qhov tseeb nws tsis tuaj yeem ua tiav. Vim tias muaj kev tiv thaiv sab hauv, yuav muaj qhov cuam tshuam tsis zoo thaum siv multimeter los ntsuas tam sim no, ua rau kev ntsuas yuam kev.
Qhov me me ntawm qhov kev tiv thaiv sab hauv ntawm qhov tam sim no, qhov qis hluav taws xob siv los ntawm multimeter thaum ntsuas tam sim no.
1. Thaum qhov ntau yam tam sim no zoo ib yam, qhov me me nyob rau hauv qhov tsis kam ntawm multimeter, qhov qis dua qhov ntsuas qhov ntsuas hluav taws xob poob qis, thiab qhov me dua qhov yuam kev hauv kev ntsuas tam sim no. Rau tib lub multimeter, tag nrho qhov ntsuas hluav taws xob poob qhov tseem ceeb rau txhua qhov tam sim no tuaj yeem sib txawv.
2. Rau tib lub multimeter, qhov loj dua qhov tam sim no, qhov me me ntawm qhov tsis kam sab hauv, thiab qhov me me ntawm qhov ntsuas qhov yuam kev. Yog li ntawd, txhawm rau txo qhov yuam kev hauv kev ntsuas tam sim no, qee zaum nws yog qhov zoo dua los xaiv qhov ntau dua tam sim no. Tau kawg, qhov ntau yuav tsum tsis txhob siab dhau kom tsis txhob muaj qhov nce ntxiv hauv kev nyeem ntawv yuam kev thaum ntsuas cov dej me me.
3. Thaum qhov kev tiv thaiv sab hauv ntawm qhov tam sim no yog kwv yees li 1 feem pua ntawm tag nrho cov kev tiv thaiv ntawm lub Circuit Court raug kuaj, tsis tas yuav xav txog qhov multimeter voltage.
