Ib is basic current, Imax is maximum current.


3 Starting:

Under conditions of reference voltage,reference frequency and power factor is 1.0, the meter should be able to start and measure the electric energy normally when meter of class 1 is 0.4%Ib and meter of class 2 is 0.5%Ib.


4 Creeping: 

Anti-creeper logical design, apply a reference voltage of 1.15 times to the voltage circuit, while there is no current in current circuit, testing output of the meter shall not produce more than one pulse.


5 Power consumption: 

≤2W (10VA)


6 Ambient conditions Standard working temperature:

-25℃~55℃Limiting working temperature: -25℃~60℃ Note: limiting working temperature for special requirements: -40℃~70℃
