3, display:
(1) JYS-2S4 4 3 row LED digital tube display, instrument of electric parameter display is a measurement of power parameters of the PT,CT value (ie: voltage = PTx input voltage values of voltage ratio, current ratio = current input current value for CTx, x display power = power voltage x current ratio). Through Panel switch button to toggle the display of voltage (first display indicator light), front row, second row, third row LED display represent the contents of UA,UB,UC or UAB,UBC,UCA readings. The unit V. Light k or m KV or MV. Displays the current (but the second display indicator lights), front row, second row, third row contents of LED display represent the IA, IB, IC readings. Its unit a. Light k or m and MA KA utility (second show at this time led) front row, second row, third row LED display the contents of the p, Q,COS ∮, The unit for w, Var. light k or m Kw, KVar, and Mw, Mvar. Points are displayed using front row, second row LED display
(2) communications: 4800/9600 programmable serial communication RS485 baud rate settings. Communication protocol using MODBUS Protocol
