Dab tsi yog kev siv ncv ua haujlwm ntawm multimeter
Ntawm lub multimeter, ncv yog lub ntsiab lus ntawm Non contact voltage. Nws siv lub hauv paus ntsiab lus ntawm electromagnetic los yog hluav taws xob teb induction los txiav txim seb puas muaj hluav taws xob. Nws zoo ib yam li kev ua haujlwm ntawm induction test cwj mem, thiab tus cwj mem xeem tsis tas yuav hu ncaj qha rau cov khoom raug them.
Nws yog siv los nrhiav cov xov hlau faus nyob rau hauv phab ntsa (koj tuaj yeem tshawb xyuas cov ntsia hlau ntawm phab ntsa ua ntej), lossis nrhiav cov faus cov hlau tawg, thiab lwm yam. Nws yog tsim rau siv nrog AC voltage siab dua. Nws tsuas yog txiav txim seb puas muaj qhov voltage, thiab tsis tuaj yeem ntsuas qhov tshwj xeeb voltage.
Yog tias koj nyiam peb Smart multimeter GVDA GD138B koj tuaj yeem nias qhov txuas hauv qab no rau cov khoom lag luam:
