FSD4-AC 6 in 1 AC electric parameter gauge with two LED screens, measure active power watt, estimated annual electricity consumption KWH (power electricity consume by 365days*8hours per one year), power factor, Voltage, Current, frequency, actual electricity consumption KWH and time counting.
Pressing switch button in the back can choose different parameter display.
Memory store after power off: Meter can store the last switch button setting even after power down. Fox example, you set the switch button to power watt, then power off. after power on, the meter will be still in the status of power watt measure.
