Q&A

Q : After I configure it with App , why App shows 'shutdown' ?
A : Only if you put a device's wire (either live wire or neutral wire, not both) in the clamp, and turn on the device, then the clamp can sense the current, and App will show it is working

Q : I suppose P= U*I, why the value shows on App is not correct ?
A : Please consider the cos(Φ).
Because As resistances do not produce any phasor difference (phase shift) between voltage and current waveforms, all the useful power is delivered directly to the resistance and converted to heat, light and work. Then the power consumed by a resistance is real power which is fundamentally the circuits average power.
To find the corresponding value of the real power the rms voltage and current values are multiplied by the cosine of the phase angle, Φ as shown.
Real Power P = I2R = V*I*cos(Φ) Watts, (W)
