Yuav ua li cas ntsuas DC tam sim no nrog multimeter
Ib qho, DC tam sim no ntsuas txoj kev
1. Ntxig qhov kev kuaj dub rau hauv COM jack. Thaum ntsuas qhov siab tshaj plaws tam sim no ntawm 200mA, ntxig cov hlau kuaj liab rau hauv mA jack. Thaum ntsuas qhov siab tshaj plaws tam sim no ntawm 20A, ntxig cov hlau kuaj liab rau hauv 20A jack.
2. Teem txoj haujlwm hloov mus rau DC tam sim no thaiv A-tsim nyog.
3. Txuas cov kev xeem coj mus rau hauv cov khoom thauj mus kuaj, ua kom ruaj khov, thiab tom qab ntawd nyeem. Yog tias nws tshwm sim li "1.", ces qhov ntau yuav tsum tau nce. Yog tias "-" tshwm nyob rau sab laug ntawm tus nqi, nws txhais tau hais tias tam sim no ntws los ntawm qhov kev sim dub coj mus rau hauv multimeter.
ob, cov lus qhia ua haujlwm
1. Xaiv lub DC tam sim no iav rau lub iav txoj hauj lwm. Thaum tsis paub qhov ntau yam tam sim no, nws yuav tsum raug xaiv los ntawm qhov siab tshaj plaws.
2. Ua tib zoo saib xyuas cov kev taw qhia tam sim no, uas yog, cov hlau kuaj liab txuas nrog rau tus ncej zoo ntawm cov khoom siv hluav taws xob (lossis muaj peev xwm siab), thiab cov hlau lead kuaj dub txuas nrog rau qhov tsis zoo ntawm cov khoom siv hluav taws xob (lossis qis. muaj peev xwm).
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, tshwj tsis yog tias tsis muaj qhov txwv polarity.
Peb, DC tam sim no ntsuas cov kauj ruam
Kauj Ruam 1: Tig lub iav ntawm multimeter mus rau qhov ntau ntawm DC tam sim no 200mA.
Kauj Ruam 2: Kaw S1 ntawm lub cev hluav taws xob.
Kauj Ruam 3: Txuas cov ntawv xeem liab mus rau 1 thiab qhov kev xeem dub coj mus rau 2, soj ntsuam kev nyeem ntawv, thiab ntsuas tam sim no ntawm cov ntsiab lus 1 thiab 2 hauv ceg Circuit Court yog 20mA.
plaub, qhov teeb meem xav tau kev saib xyuas
1. Yog tias koj tsis paub qhov ntsuas tam sim no ua ntej siv, teeb tsa lub zog hloov mus rau qhov siab tshaj plaws thiab maj mam txo nws.
2. Yog tias nws tso tawm raws li "1.", nws txhais tau hais tias qhov ntau me me dhau lawm, thiab qhov hloov pauv yuav tsum tau teem rau ntau dua.
3. Nws txhais tau tias qhov siab tshaj plaws input tam sim no yog 200mA. Tshaj tam sim no yuav hlawv tawm lub fuse, uas yuav tsum tau hloov dua. 20A ntau yam tsis muaj kev tiv thaiv fuse, thiab qhov ntsuas tsis tuaj yeem tshaj 15 vib nas this.
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 qhov ntsuas tam sim no tiav lawm, tus cwj mem liab yuav tsum tau muab tso rau hauv lub qhov "VΩ". Yog tias koj tsis nco qab cov kauj ruam no thiab ntsuas qhov hluav taws xob ncaj qha, qhov taw qhia lossis lub zog hluav taws xob yuav raug muab pov tseg, thov ua haujlwm ceev faj!
