Yuav ua li cas ntsuas tam sim no nrog multimeter
1. Xaiv qhov ntau
DC tam sim no ntau yam ntawm multimeter yog cim nrog peb ntau yam: 1mA, 10mA, thiab 100mA. Xaiv qhov loj me hauv Circuit Court, thiab yog tias koj tsis paub, siv qhov ntau tshaj plaws.
2. Kev ntsuas ntsuas
(1) Txuas lub voj voog kom lub teeb-emitting diode emit lub teeb ib txwm.
(2) Xaiv qhov ntau ntawm cov multimeter.
(3) Tshem tawm cov hlau lead ntawm qhov nruab nrab ntawm cov potentiometer thiab cov ncej tsis zoo ntawm lub teeb-emitting diode, thiab lub teeb-emitting diode yuav tawm mus.
(4) Txuas lub multimeter nyob rau hauv series ntawm breakpoint. Lub breakpoint txuas nrog lub zoo ncej ntawm lub hwj huam mov yuav tsum tau txuas nrog lub liab xeem lead, thiab lub breakpoint txuas nrog rau cov tsis zoo ncej ntawm lub hwj chim mov yuav tsum tau txuas nrog rau cov dub xeem lead. Lub diode yuav ci dua. Qhov ntsuas tus nqi taw qhia los ntawm tus pointer ntawm multimeter yog tus nqi tam sim no ntawm lub teeb-emitting diode.
(5) Nyeem tawm tus nqi tam sim no dhau los ntawm lub teeb-emitting diode.
