Current Ac 1a/5a Digital Multi - Function Meter Easy Operating 48 * 48mm Mini Size
1. Product Description:
Series of WD-DIUH Single-phase current/voltage/power factor meters are used for measuring and monitoring the power distribution system. This series of meter can measure the voltage, current, active power, reactive power, apparent power, power factor, frequency, active energy, reactive energy and some other power parameters.
It combines the measurement, the analysis and the operation together, makes the information become clearer, and the operation become easier.

4. How to Set the Meter?
CT=Current transformer primary current value/Current transformer secondary current value
DC current CT Value:
CT=Shunt primary current value/5(Signal input DC 75mV)
CT=Display value/1(signal input DC 20mA,DC 4-20mA)
PT=Voltage transformer primary voltage value/Voltage transformer secondary voltage value
PT=display value/input value
1)Indicator light:"k":thousand,K means that the practical value is display is 1000 times.
2)Display character explanation:
- Character Instruction Parameter and specification
SET Setting 0000-9999
CT Current ratio 0001-9999
PT Voltage ratio 0001-9999
