Taw qhia rau qhov voltage Gear ntawm multimeter:
Thaum kev sim lossis kev tsim khoom, nws tuaj yeem siv los ntsuas qhov voltage ntawm txhua tus pin ntawm lub cuab yeej thiab muab piv rau qhov qub voltage los txiav txim seb puas puas. Nws kuj tseem tuaj yeem siv los txheeb xyuas tus nqi ntsuas hluav taws xob ntawm Zener diode nrog tus nqi hluav taws xob me me. Lub hauv paus ntsiab lus yog raws li nram no: R yog 1K, thiab qhov voltage ntawm lub hwj chim mov davhlau ya nyob twg nyob ntawm lub nominal voltage regulator tus nqi ntawm lub Zener raj, uas yog feem ntau loj tshaj lub nominal voltage. Tshaj 3V, tab sis tsis ntau tshaj 15V. Tom qab ntawd siv lub multimeter txhawm rau txheeb xyuas tus nqi hluav taws xob ntawm ob qho kawg ntawm D raj, tus nqi no yog qhov tseeb voltage tswj tus nqi ntawm D raj.
