1.Measuring Range: Voltmeter Ammeter the voltage range is AC80V-260V,the current range is 0-20A,the power test range is 0-4.5KW,the energy range is 0-9999Kwh.
2.Built-in Current Shunt and LCD screen: The voltmeter is built-in current shunt, so you do not need to spend money in other items, and it simplifies the wiring diagram. And the amperage meter can display voltage, current, active power and energy at the same time.
3.Protection function: The AC voltmeter is designed with power alarm threshold ,overload alarm function(over power alarm threshold, backlight and power flashing to alarm) and The reset function of energy key.
4.Application: The meter can not only work with a generator, solar panel setup but also monitor energy usage on machine like refrigerator, dehumidifier, washing machine.
5.Data storing function: Short press 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.
