Multimeter ntsuas DC voltage
Kev ntsuas cov kauj ruam:
1. Xaiv qhov ntau. DC voltage ntau ntawm multimeter yog cim nrog "V" thiab muaj tsib yam ntawm 2.5 volts, 10 volts, 50 volts, 250 volts thiab 500 volts. Xaiv qhov ntau raws li qhov hluav taws xob muab hluav taws xob voltage hauv Circuit Court. Txij li thaum lub hwj chim mov voltage nyob rau hauv lub Circuit Court tsuas yog 3 volts, 10 volts yog xaiv. Yog tias koj tsis paub qhov voltage, koj yuav tsum xub ntsuas nrog lub siab tshaj plaws voltage range, thiab maj mam hloov mus rau qhov qis voltage ntau.
2. Cov txheej txheem ntsuas. Lub multimeter yuav tsum tau txuas nrog nyob rau hauv parallel nrog lub Circuit Court nyob rau hauv kev sim. Tus cwj mem liab yuav tsum tau txuas nrog kev sib txuas ntawm lub voj voog nyob rau hauv kev sim thiab tus ncej zoo ntawm lub hwj chim, thiab tus cwj mem dub yuav tsum tau txuas nrog kev sib txuas ntawm lub voj voog nyob rau hauv kev sim thiab cov ncej tsis zoo ntawm lub hwj huam mov.
3. Kev nyeem ntawv raug. Ua tib zoo saib lub dial, DC voltage nplai kab yog kab thib ob, thaum siv 10V nplai, qhov ntsuas qhov ntsuas hluav taws xob tuaj yeem nyeem ncaj qha nrog kab thib peb ntawm cov lej hauv qab kab. Thaum them nyiaj mloog mus rau kev nyeem ntawv, kab ntawm qhov pom yuav tsum ncaj qha rau ntawm tus taw tes.
