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.
