Txoj kev loj hlob ntawm digital multimeter
1) Kev sib koom ua ke
Lub handheld digital multimeter siv ib-chip A / D converter, thiab lub peripheral Circuit Court yog yooj yim, yuav tsum tau tsuas yog ib tug me me ntawm pab chips thiab Cheebtsam. Nyob rau hauv xyoo tas los no, cov chips tshwj xeeb rau ib leeg-chip digital multimeters tau tawm mus tas li, thiab qhov ua tiav tsis siv neeg ntau yam digital multimeter tuaj yeem tsim los ntawm kev siv ib qho IC, uas tau tsim cov kev mob zoo rau kev tsim kom yooj yim thiab txo cov nqi.
2) Kev siv hluav taws xob tsawg
Tshiab digital multimeters feem ntau siv CMOS loj-scale integrated circuit A/D converters, thiab lub hwj chim noj ntawm tag nrho cov tshuab yog tsawg heev.
