It is used in the real-time measurement and indication of voltage, current, and frequency in the three-phase electrical line and displays the values with serval-row LED. One meter can finish the measuring tasks of several common meters. It can be added the analog, transmitting, higher/lower limit alarm, RS485 communication according to the customer's requirement. And it is with the display and detection functions of max. value, min. value current demand and max. demand value.
