Name: JYS-2S4 (CDJ194-2S4) Multifunction Power Meter
Dimensions: Dimensions: 120x120mm opening size: 112x112mm
Features: 4-digit 3-row LED digital tube display, through the switch can be displayed commonly used parameters such as electricity.
At rated voltage, reference frequency and COS ∮=1.0Of the conditions, the load current is 0.001In, the meter can start and continuous measurement of power.
When 115% of the rated voltage is applied, the current loop is de-energized and no current is drawn.

3, display:
(1) JYS-2S4 uses 4-bit 3-row LED digital tube display, the instrument's power parameter display is PT, CT a measured power parameters of the actual value (ie: voltage = voltage ratio PT × input voltage, current = Current ratio CT × input current value, display power = power value × voltage ratio × current ratio.) Through the panel switch button to switch the display voltage (at this time the first indicator light) the first row, The display of UA, UB, UC or UAB, UBC, UCA is shown in unit V. The indicator light K or M indicates KV and MV. Display current (but the second display indication The first row, the second row, the third row of LED display content, respectively, IA, IB, IC readings. The unit is A. indicator K or M light that KA and MA real utility (this time the second Display indicator light) The first row, the second row, the third row of LED display of the contents of the representative of P, Q, COS ∮, The unit is W, Var. Indicator K or M light that Kw, KVar and Mw, Mvar. Point through the first row, the second row of LED display
(2) communication: serial communication port for the RS485 baud rate 4800/9600 programmable settings. Communication protocol using MODBUS communication protocol
