Kuj tsis paub meej zaus lub hwj chim sensor txhais
Cov ntsuas hluav taws xob zaus hloov ua hluav taws xob ua piv txwv AC ntsuas ntawm qhov ntsuas voltage thiab cov cim tam sim no, thiab tom qab ntawd txuas cov nqi piv txwv rau digital input theem nrab meter los ntawm cov kab xa hluav taws xob xws li cable lossis hluav taws xob optical, thiab digital input theem nrab ntsuas cov piv txwv qhov tseem ceeb ntawm qhov hluav taws xob thiab tam sim no. Nws tuaj yeem tau txais cov tsis xws li voltage RMS, RMS tam sim no, lub pib siv hluav taws xob, lub hauv paus tam sim no, cov pa hluav taws xob, harmonic tam sim no, lub zog tseem ceeb, lub zog tseem ceeb, thiab lub zog harmonic.
