ETCR4400 Multifunction Three-Phase Phase Voltammeter

ETCR4400 Multifunction Three-Phase Phase Voltammeter
Product Main Function
Simultaneously measurement the voltage amplitude, current amplitude, voltage phase, current phase, the phase between voltage and current, frequency, power, active power, reactive power, display the vector diagram of three-phase voltage and three-phase current in real time.The meter can judge the three-phase phase sequence, sensibility and capacitance circuit, test the secondary circuit, check whether the wiring of the watt-hour meter is correct or not, overhaul the line equipment and so on.
Simultaneously two-channel AC current measurement, range: 0.001A-20A
Simultaneously two-channel AC voltage measurement, range: 2V-700V
Simultaneously phase test among UI, II, UU, range: 0°~360°
Product features
1.High measurement accuracy, voltage and current accuracy upt to class 0.3; phase accuracy is ±0.3°.
2.A variety of measurement modes, can be single-phase, two-phase and three-phase measurement mode;Three-phase 4-wire and three-phase 3-wire measurement mode.
3.The measuring personnel only need the wiring operation, the instrument automatic measurement, and real-time update data, which is convenient the field analysis; The instrument adopts complete isolation technology to avoid safety accidents.
4.Touch color screen, easy and convenient operation, large capacity lithium battery, USB interface, data upload function and so on.
