PZEM-020 10A AC Digital Display Power Monitor Meter Voltmeter Ammeter Frequency Factor Meter (Without CT) is a  monitoring system for parameters like voltage, current, active power, energy, frequency, power factor, etc. The display comes with a high-quality current sensor with the help of which you can easily measure the current flowing through the wire by using the noncontact method, which means there is no physical contact between the wire and the meter.

Backlight control:

  Short press the key to turning on or off the backlight, the backlight has a memory function, it can store the on or off state when power off. 

Reset energy

• Step1: Long press the key for 5 seconds until the energy value flashes, then release the key.
  
•  Step2: Short press the key again, then the energy value is cleared, and exit the reset flashing state.
•  Step3: If there is no operation on the key within 5 seconds, it means the energy value is not cleared and will exit the reset state.

   Set power alarm threshold

•   Step1: Long press the key until the LCD screen display “SET CLR”, then release the key to enter the setting state
•   Step2: Power window displays the current power alarm value and the last digit begins to flash, then you can short press to plus 1, when there is no operating over 3 seconds, it will switch the digit position automatically, the setting method is as same as the above.
•   Step3: After finish, the setting, long press the key over 5 seconds will store automatically and exit, the range of active power threshold is 0.0~2.5kW.
