1. Introduction
This is a digital device, able to measure all the variables associated with an electrical line, as is
shown in the following table. It accepts the three current and three voltages signals in a 4 wire
configuration. It is also possible to use it in 3 wire configuration, using two or three current
transformers.
2. Features and Technical Parameters
2.1 Features
The operating hours& the consuming power are shown in a alternate display but have
synchronous display—to be displayed at the same time on the same screen.
The meter has the function to memorize all the data when the power off .When the machine is
switched on again after the power off ,the measurement data should continue running on and
show the summing up amount in numbers. ( Note:the meter can not show the data when power
off )
The meter has the displaying of the voltage, current, power, MD.
The meter has reset function. People can reset the data through Modbus RTU communication
