B. Appearance and Key function description
The description of keys/LCD function
1. In normal display state, short press UP key will reversed circularly display time, power, energy, current, voltage.
2. In power alarm threshold setting state, press the UP key will +1.
3. Short press the UP key will exit the reset state when energy and time are in the reset state.
1. In normal display state, short press DOWN key will sequential circularly display voltage, current, energy, power, time.
2. In power alarm threshold setting state, press the DOWN key will -1.
3. Short press the DOWN key will exit the reset state when energy and time are in the reset state.
1. In power display state, long press 3 seconds will enter into the power alarm threshold setting state
2. In energy or time display state, long press 3 seconds will enter into the energy or time reset state.
1. In normal display state, short press OK key will turn on or off the backlight.
2. In power alarm threshold setting state, press OK key to switch the setting digits
3. In energy or time reset state, press OK key will clear the energy or time and quit the reset state

E. Wiring diagram
F. Dimension diagram
There are three types of power: active power (P represents / unit W), reactive power (Q represents / unit Var), apparent power (S represents / unit VA).
And the power of our product is active power.
Active power is calculated as: P = U * I * cosφ, cosφ represents the power factor, for purely resistive loads (such as incandescent, heater, etc.) the power factor is generally close to 1, for inductive load and capacitive load, the power factor is between 0-1; so when you test the purely resistive load, the power(P) is substantially equal to or close to U * I; but when you test inductive or capacitive loads (such as refrigerators, washing machines, televisions, computers, etc.), P <U * I . As for the specific number is related to the power factor, for each appliance has different power factor, so please believe the value of our product.
