Quick Details
Description
1.1 Wide measuring range :current 0.01A-100A,voltage:40V-480V
1.2 The measure ratio is about 2 to insure the meter has the highest accuracy in the measuring range.
1.3 Strong measuring functions: three phase four wires active energy, three phase three wires active energy, three phase three wires sine reactive energy, three phase four wire 90° reactive energy, three phase three wires 60°reactive energy.
1.4 Easy to operate: there are 5 operating buttons at the bottom of the screen, which are corresponding with the reminding symbols on the screen.
1.5 The standard meter has RS-232 communication interface, which can communicate with PC in two ways. It can transmit the measuring data to PC as well as measure automatically controlled by PC.
