Main features:
·           Automatic/manual measurement of single phase, three phase three wire, three phase four wire active and reactive induction energy meters and static energy meters (by sampling pulse)
·           Comparison measurement of voltage, current, power, power factor, phase, frequencyof other electric instruments and transmitter by
·           Measurement of secondary burden of PT and CT; proofreading of constant of energy meter; energy measurement of four quadrants
·           Simultaneous measurement of errors for active and reactive energy meters; simultaneous measurement of errors of master and sub meter; automatic calculation of standard deviation estimates
·           Simultaneous measurement of active and reactive errors for load management terminal and distribution/ substation monitoring terminals; measured data can be read and stored via RS 485 port or IR port
·           Equipped with RS485,RS232, IR and USB port
-       Via the USB port, information of customers and energy meter can be downloaded from the marketing management system; measured data can also be uploaded to the management system
-       KWh, voltage, current, power and phase angle ect of energy meter and management terminals can be read via RS485(RS232) or IR port; also, broadcasting or command (according to the reference meter) time pairing provided
·           Self adjusted clamp-on CT’s enable long term accuracy; minimum measuring range of current to 1mA (with 1A/5A clamp-on CT’s)
·           Wiring testing is accessible on a new no-load field (with PT/CT)
