Display format: 0.00~99.99

Key

1.Backlight control

Short pre the key to turn on or off the backlight, the backlight has memory function, it can store the on or off state when power off.

2.Reset energy

Step1: Long pre the key until the power display area display “CLr”, then release the key.

Step2: At this moment, the energy is fing to prompt this is the energy reset state, if short pre the key again, then the energy value is cleared and exit the reset fing state.

Step 3: If there is no operation within 5 seconds, it means the energy value is not cleared and will exit the reset state.

3.Set voltage alarm threshold

Step1: Long pre the key until the power display area display “SET”, then release the key.

Step2: After enter this state, the voltage area display the current high voltage alarm value, the current area display the current low voltage alarm value and the last digit begin to f, then you can short pre to plus 1, when there is no operation over 3 seconds, it will switch the digit position automatically, from the high voltage alarm value to the low voltage alarm value, there are total six digits, the range of the voltage alarm threshold is 6.5~99.9V;

Step3: After finish the setting, long pre the key until the screen display “P” ,that means you set succefully and will exit the setting state automatically.

Note:

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 hines, televisions, computers, etc.), P
