Function Feature
	It is used to real-time measure the multiple electric parameters of the three-phase electricity 
lines at the same time, and adopts the five-row or four-row LED to display. It has the 
following types: 
★Three-phase V or three-phase A combination meter: it can measure the three-phase voltage and three-phase current at the same time. Thereinto, three-phase voltage takes the fourth row figure to automatically loop display or manually switching display. 
★Three-phase V+A+Hz combination meter: it can measure the three-phase voltage, three-phase current, and frequency at the same time. Thereinto, the three-phase voltage takes the fourth row figure to automatically loop display or manually switching display. 
★Three-phase V+A+Hz+W combination meter: it can measure the three-phase voltage, three-phase current, frequency, power and power factor at the same time. Thereinto, the fourth rowfigure can be switched to display the phase voltage and line voltage of each phase, the fifth row figure can be switched to display the frequency, active power and power factor.

	Basic Parameter
	★测量范围: 
★  Measuring range:
Current: AC 0.05 ~ 6A, when it is more than 6A, it needs to connect a */5A or */1A CT externally and set the display multiply power. Voltage: AC 25~600V,Frequency: 40~70Hz 
★  Accuracy class: 0.5 
★  Power consumption of input loop: <0.5VA / phase
★  Resolving ability: for voltage, maximum is 0.1V; for current, maximum is 0.001A, decimal point will shift automatically; for frequency, maximum is 0.01Hz
★  Measuring rate: about 1 time / s
★  Auxiliary power supply: AC220V(+10%-20%)or AC 380V(+10%-20%)
★  Power consumption of auxiliary power supply: <3VA
★  Working environment: temperature is +10~+50℃, humidity <85% RH,without any corrosive gas
★  Safety withstand voltage: using the AC 2kV withstand voltage test to measure between the input terminal and the power supply terminal
